4 Common TPO Roofing Problems to Consider in 2024

One of the more common roofing systems is known as TPO or a single-ply membrane.

While its popularity stems from various benefits, consumers should also be aware of potential TPO roofing problems before making a final decision.

TPO membranes are currently one of the fastest-growing commercial roofing systems in 2024.

TPO Roofing Benefits

There are many benefits to implementing a TPO roofing system onto your current commercial roof. It has great strength, durability, and flexibility.

That means being able to stand up to a build-up of dirt, resistance to tears, and mold growth as well.

Perhaps its best trait is that it is energy efficient. TPO membrane is meant to reflect and resist those UV rays that can heat up a building, making it easier and more efficient to keep the building cooler.

This, in turn, means that the building doesn’t need to use the HVAC system to compensate.

TPO roofs are a highly efficient and effective roofing system for commercial roofing buildings, especially flat roofs.

TPO Roofing Problems

As good as these roofing systems are, there are four common TPO roofing problems to be aware of.

1) Easily Punctured Membrane

Of all the TPO roofing problems there are, this is the one that is probably the most problematic. While this roofing system can be walked on, and it is both flexible and lightweight, the membrane itself can be easily punctured.

With commercial roofs, one of the more common TPO roofing problems is a high volume of foot traffic compared to other types of buildings or roofing structures.

The single-ply membrane roofing doesn’t have a hard-top layer that is meant to protect the layer of synthetic rubber from things like gravel, dropped tools, or loose screws.

Common TPO roofing problems like this see those materials pushed into the rubber membrane, breaking or tearing it by creating holes in the rubber and insulation.

This leaves the roofing system more vulnerable to leaks further down the line.

With a proper primer, you can take this one off the list of TPO roofing problems by giving it an extra layer of insulation and protection that it did not have previously.

2) Expired Warranty

Here’s a key tip: purchase the warranty when you have a new roofing system installed. This is because most manufacturer warranties will require the contractor to perform those repairs for the first couple of years after the initial installation.

Warranties can also be anywhere from 15 to 30 years. Common TPO roofing problems can be solved by having a warranty on your side.

Stay on top of it because when your warranty expires, you could be susceptible to higher maintenance and repair bills, especially if your facility has encountered problems.

It cannot be emphasized enough that having a warranty is a great way to keep TPO roofing problems in check.

Things happen, leaks occur, damage can be done, and having a quick, reliable fix on your side is far easier than finding a repair service on your own and eating the costs out of your pocket.

Protecting yourself is a little more costly than you may have thought, but it is a great way to protect yourself from persistent problems or future repair bills. That alone makes it worth the cost alone.

3) UV Rays Degrading the Adhesives

Wear and tear is certainly one of the most common TPO roofing problems. Actually, scratch that. It is one of the most common problems with any roofing system out there.

This is because it is exposed to the elements 24 hours a day, seven days a week.

That also means constant exposure to the sun. Those harmful UV rays can significantly damage a roofing system over time.

It can happen in many different ways, but the most common TPO roofing problems occur when those UV rays degrade the adhesives used to attach the membrane to the substrate.

Not only that, but those adhesives are also what seal the seams of the membranes together to create the waterproof seal that keeps your roof safe in even some of the harshest of weather conditions. Without that seal, your roof is vulnerable.

When there are punctures, tears, or other damage to your roof, those UV rays can come into contact with the adhesive layer and cause a lot more damage when those adhesives deteriorate.

That is why it is important to ensure that the membrane sheets overlap during installation. This will block the adhesives from exposure to UV rays and prevent those TPO roofing problems from occurring, at least not consistently.

4) Longevity

Perhaps the most common TPO roofing problems are that they tend not to last as long as some other roofing systems. TPO roofing is definitely strong and durable, but it is still something of a young technology in the roofing industry.

That means that the formula that is used to produce this TPO material is still far from perfect as the manufacturers attempt to find a balance between affordability and durability.

This means that, along the way, some of these roofing systems have had common TPO roofing problems like material failures and seam cracks.

Some improvements have been made along the way, but it may be some time before the formula is perfected. Still, TPO roofing systems are affordable and tend to be durable more often than not.

All of these TPO roofing problems are fairly common, and that means that they are relatively easy to solve as well.

Keeping this in mind, it is easier to keep them working optimally and avoid having to deal with major issues or damages to your roofing system.

Final Takeaway on TPO Roofing Problems

TPO roofing systems offer various benefits to commercial properties, making them one of the most popular choices in 2024.

However, TPO roofs also come with a set of potential problems that consumers should be aware of before making a final decision.

While these problems are not severe enough to dwindle the popularity of this ascending roof type, they are worth exploring when considering all your roofing options.

How Much Weight Can a Concrete Roof Support?

When considering roofing materials, there are a lot of factors to take into consideration. Durability, cost, and a litany of other things can impact which material you go with for your residential or commercial roof. But weight capacity is another important one.

Some mistakenly believe that concrete roofs are endlessly sturdy, regardless of contributing factors. That is not the case. In the following article, Roofer’s Guild explores the nuances of this topic.

How Much Weight Can a Concrete Roof Support (Cover)

Key Takeaway

A concrete roof can support about 1,200 pounds per square foot. However, variables like thickness, reinforcements, and installation quality all contribute to its maximum capacity.

How Much Weight Can a Concrete Roof Hold Per Square Foot?

While the answer to this question can vary greatly on several factors within the concrete itself, a good rule of thumb is around 1,200 pounds per square foot, depending on the thickness of the concrete and whether or not it has any reinforcements.

A common mistake is that amateur roofers just assume that concrete is impossibly strong, but it has weight restrictions just like any other material.

Reinforcing the Roof

With newer installations, this is likely a common practice performed by the roofer doing the job. But in older homes, the question of weight support becomes irrelevant if it is quite old or has experienced a lot of damage.

While a complete replacement is the most ideal of scenarios, the cost of a new roof is often not so realistic.

That is where reinforcing the roof can help get a longer life out of your roof while implementing a fast, quick repair and reinforcement that will keep the structural integrity of the roof sound for some time.

Again, it is highly recommended that you get a new roof wherever you can. Still, there are a couple of ways to reinforce your roof to give it a little boost in terms of life span.

Addressing Repairs with Patching

If the deterioration or damage to your concrete roof isn’t terribly bad, it can be patched to extend its life a little longer.

But if you are implementing extensive patchwork, it is important to note that you should not assume that it can take on a proper load and will never be able to handle the maximum weight.

The condition and age of the roof are essential factors for determining the amount of weight it can support so that you or a roofing contractor can safely traverse the roof.

Strengthening Existing Trusses

This is a way to add durability to your roof. By using 2×4s, you simply combine them with any existing trusses that may be in place from one end of the structure to the next. This can allow for extra stability.

However, this is not meant to be a long-term solution if the roof is showing signs of wear and deterioration.

Exercise caution whenever getting on the roof and understand that this is just prolonging the eventual replacement of the roof entirely.

Signs That the Roof is Failing

While not every roofing structure will provide clear warning signs, the question of weight support becomes moot once the damage is obvious.

Existing damage makes traversing the roof unsafe and a serious hazard.

There are definitely a few things to keep an eye out for regarding the condition of your roof and whether or not there may be issues currently occurring.

Leaks

The biggest issue plaguing roofing systems, concrete roofs, too, is in the form of leaks. If you see multiple wet spots in your ceiling or moisture retained on the roof, it is a strong sign that the roof has a weak spot that can lead to bigger issues.

Leaks are a huge issue not only for the roofing system itself but for the structural integrity of the rest of the building.

If that water is allowed to persist, it has the chance to rot and decay wood that could provide structural support and lead to mold growth, making it a hazard to the air quality in the building.

Cracks

Cracks are a clear indication that there may be problems with your roof. This can mean that stress is being implemented onto the roof and spreading outward in other directions.

This can lead to serious problems with your concrete roof, making it structurally vulnerable and making it unsafe to be near.

Small cracks are not a terribly big idea, but calling in a proper roofing contractor to survey the scene and understand the situation will allow you to stay ahead of any potentially disastrous situations.

It is always better to exercise caution in scenarios such as these.

Other Weight Considerations for Concrete Roofs

So many factors determine “how much weight can a concrete roof support” that it isn’t a black-and-white question.

A concrete roof can safely support around 1,200 pounds (0.54 t) per square foot when completely healthy and showing no signs of wear and tear.

But that figure can drop exponentially when leaks, cracking, chipping, and other damage rears their ugly head. If you see areas of your concrete roof that look concerning, the safest bet is to avoid stepping in those areas and leave it to the professionals.

Your concrete roof can stand up to a lot and prove to be a durable choice in roofing material, but it is certainly not immune to its own issues. You can consult this roof load calculator if you are worried about snow.

Final Thoughts

A concrete roof can typically support about 1,200 pounds per square foot. However, variables like thickness, reinforcements, and the quality of installation can all alter that general threshold.

Roofing contractors and property owners can both take measures to maximize the concrete roof’s weight capacity, including performing repairs, adding reinforcements, and strengthening the trusses.

TPO vs. Modified Bitumen Roofing System (Cost, Lifespan, Etc.)

TPO vs. Modified bitumen is a common debate for many commercial building owners.

Generally speaking, two kinds of commercial flat roofing systems are most commonly found in the Northeast. These are modified bitumen and thermoplastic polyolefin or TPO. The former has been around since the 1970s and is one of the more traditional methods of flat commercial roofing.

TPO has been around since the 1990s, and both do well in extreme temperatures, both extremely hot and bitterly cold. And given the locale (the Northeast), this is a perfect set of traits to have to stand up to the huge swings in temperature.

However, TPO commercial roofing is surging in popularity. You might not have realized that TPO roofs are installed more than all other flat roof alternatives combined, including a PVC flat roof.

The following post will examine both kinds of roof systems in depth. It will include the cost, expected life and longevity, and overall value of each roofing system so that you can make the most informed decision possible.

Key Takeaway

TPO is clearly better than modified bitumen because of its energy efficiency, longevity, reliability, customization, and versatility. As a result, TPO roofs are also more expensive.

Modified Bitumen Flat Roofs

One of the primary benefits of using a modified bitumen roof is that it comes at a lower installation cost. However, one of the biggest disadvantages is that many major commercial roofing contractors have stopped installing them, mostly due to the surge in popularity of TPO roofs. Some have gone as far as to start installing TPO over modified bitumen.

As stated previously, modified bitumen began in the 1970s and became a major upgrade over traditional asphalt roofs of the time. It is termed “modified” because of the addition of substances like styrene butadiene styrene (SBS) or atactic polypropylene (APP), which were intended to enhance both flexibility and longevity of the roof, especially compared to those old asphalt roofs.

Over the years, several issues have arisen with modified bitumen roofs.

Lack of APP Modifier

The first is that, although an APP-modified bitumen roof is designed to resist things like UV-light damage, cracking, blistering, and oxidation, there has been a lack of standards in the industry which has led to manufacturers skimping on the addition of that APP as a modifier.

What is the downside of that, exactly? This omission causes the roof to underperform, leading to costly repairs. In the worst case, it could mean that your commercial roof needs replacing, adding another costly endeavor to your plate.

Drainage Issues

The second issue with modified bitumen flat roofs is that, although the gravel spread over a modified bitumen roof is intended to offer hazard and UV protection, that granular surface makes it more difficult to correct drainage issues and detect leaks.

Those drainage issues and leaks can persist far longer than they might with a TPO roof, which means that there can be a buildup of water that can damage the roof’s structure. When something like this happens, it can create structural integrity issues that can lead to even more costly repairs to your commercial business than you had ever expected.

Fire Hazard

The third issue with modified bitumen flat roofs is that using an open flame torch during installation can be a fire hazard. Mishandled torch use has caused more than a few instances of building burning. The risk here is definitely substantial, and it can be substantial enough that some insurers will not even cover roofers who apply modified bitumen using the open torch method.

Open torch installations of modified bitumen are becoming rarer. That said, the cost of a modified bitumen roof remains appealing to some.

Thermoplastic Polyolefin (TPO) Flat Roofs

TPO is also known as flexible thermoplastic polyolefin (FTPO) roofing. Generally speaking, three different kinds of commercial roof installations involve TPO: ballasted, fully adhered, and mechanically fastened.

TPO is considered one of the best values in commercial roofing because it offers a variety of key advantages. Value and longevity are two of the most critical aspects of a commercial roof.

Eco-Friendly

The tear-resistant single-ply membrane is tough and resists oil, grease, and chemical spills. Not only that, but TPO roof systems are also fully recyclable and UV-resistant. Best of all, TPO single-ply roofing is often considered a “green” option because no plasticizers are included in the formulation process.

Color Variety

One of the cool aspects of the rise of TPO roofs in commercial roofing installations is that many building owners and managers now have the option of selecting from over a dozen colors, including white, which has proven to be energy-saving.

The great thing about this is that now you can match your new roof to the exterior color of your building. This might not seem like much, but matching that color scheme can make your building stand out to passersby.

Reduced Energy Costs

Some of those initial costs of installing an Energy Star-rated TPO roof can be recovered through lower energy costs over the life of that commercial roof. That makes it easier to take on the initial costs of installing the TPO roof to your commercial building.

No Tear-Off

Additionally, it is possible to apply TPO roofing systems over preexisting modified bitumen and metal roofs as long as the current roof is in sound condition and not substantially worn or damaged. Applying the new roofing system over the top of an existing roofing system eliminates additional tear-off costs and will reduce the overall disposal expenses. That is a win-win across the board.

Reheatable and Weldable

TPO is also reheatable and weldable, meaning that it is possible to re-weld any seams that require it years later. Smooth-surfaced TPO roof systems are easier to maintain and clean than granular-surfaced roofs, like modified bitumen. Cleaning and maintaining your roof properly means that the roof will hold up for longer, saving you from having to get a new roof for a long time to come.

Thickness Variance

The thickness of the standard TPO single-ply membranes can vary a bit. The “default” is around 45 mils but can be as big as 800 mils. If your roof is in an area where punctures are more likely – due to falling large branches or other sharp objects – you might want to look into a thicker membrane to ensure that your roof does not get punctured by any of those falling objects.

Installation Quality

As with any commercial roofing system, the installation here is key. Whenever a TPO roof fails, it is often the result of damage done during the installation process. If it doesn’t, it is because seams were not properly welded during the installation process.

These seam failures can lead to leaks or potential catastrophic failures when extreme winds occur, causing wind uplift. While these are certainly worst-case scenarios, they are things to be aware of when installing a TPO roof. When you hire a skilled, experienced roofing contractor to handle the installation process, you generally don’t have to worry about these worst-case TPO scenarios.

The premier TPO manufacturers consistently produce high-quality, longer-lasting TPO membranes that you can be confident in and that will last longer than ever before.

Proper TPO installation methods from a certified commercial roofing contractor will ensure that the TPO roof is installed properly and likely won’t fail.

Final Call: Modified Bitumen vs. TPO (TPO is King)

Despite being cheaper, there are just too many downsides to using a modified bitumen roof to make it a viable option anymore. TPO is more energy-efficient, more reliable, and more versatile than its counterparts in the roofing industry.

Combined with the ability to customize the color of your roofing surface, there is just no matching TPO as a commercial roofing option. They also last longer than bitumen flat roofs, meaning you save on the costs of a potential installation that would occur sooner rather than later with a bitumen roofing system.

When you run a commercial business, there are a million things you must keep in mind and worry about; your commercial roof should be at the bottom of that list. When installing a TPO flat roof on your building, you properly protect it from even the most extreme elements for a long time.

When your heating and cooling bills are far less than ever, you can save a ton on installation costs over the years. You can have confidence in your commercial roof’s ability to stand the test of time and handle the elements easily, allowing you to focus on the most important aspects of your business, like generating revenue to keep that business going.

TPO is the reigning king of roofing materials and will likely continue to hold that spot for a long time.

How Long Do Rubber Roofs Last?

With proper upkeep and weather conditions, your standard rubber commercial roof will last 40 to 50 years.

Of course, this assumes proper and preventative maintenance. No roof will last half a century on its own without preventative maintenance.

While that may sound like a hassle, preventative maintenance entails simple inspections and patchwork that address minor damages before they accumulate.

If your area experiences extreme weather each year, the rubber roof life expectancy decreases by a few years. Still, rubber roofs are generally very durable and meant to last a long time.

How Long Do Rubber Roofers Last (Blog Cover)

Key Takeaway

A typical rubber commercial roof will last between 40 and 50 years with the proper maintenance and mild weather patterns.

Benefits of Rubber Roofs

If you are a contractor or are familiar with the roofing game, you may have heard of EPDM. This is Ethylene Propylene Diene Monomer, more commonly known as rubber roofing.

Most contractors will recommend that commercial property owners invest in these rubber roofs.

Rubber membrane roofs have advanced durability, life expectancy, and cost per square foot, making them one of the best replacement options for any damaged roofing material.

And while it certainly has disadvantages, there are more than enough reasons that EPDM roofs are one of the most common options for commercial properties.

Ease of Installation

Properly installed rubber roofs make your roof seamless. Without seams, your roofing is more moisture-resistant and virtually leak-free.

With other roofs, there is the risk that shingles or individual panels could peel and rise, exposing the roof underneath to the additional risk of leaking.

But with the seamless rubber roof installation, you no longer have to worry about those pesky leaks.

Rubber roofs have the same properties as PVC, TPO, and other roofing materials that are more expensive to install. Again, it all comes down to the quality of the installation.

Subpar or faulty installations eliminate the full range of capabilities that the rubber roof can offer.

Lightweight

Your standard rubber roof weighs just about two pounds per square foot. This makes it lighter than something like modified bitumen, but it remains more durable.

Being lighter in weight also means that it puts less stress on the roof over time. This can do wonders for the health of your commercial roof over the life of the building.

Its lighter weight also means that it is easier to transport and install. Heavier materials are challenging to move up and down ladders or stairs, but rubber material is more user-friendly.

Durability

Rubber roofs are very durable, on a level with PVC and TPO. EPDM is actually durable enough to support things like rooftop gardens as well. Because the material is seamless, it can lock out moisture and prevent the growth of fungi or other roof-harming life forms.

With proper installation and yearly preventative maintenance—inspections to check for any cracks in the façade that could allow moisture to enter—your rubber commercial roof should last at least 40 years.

Professional Rubber Roof Installation

The first course of action for installing a rubber roof should be to call in a commercial roofing contractor.

A contractor or roofer will have a litany of experience when it comes to installing these roofs, and the chance that something goes wrong will drop drastically.

If you insist on doing the work yourself, you must follow certain steps to ensure that the job is done correctly and that your rubber roof is installed properly.

Rubber Roof Installation Steps

Roof Cleaning

The first step is to prepare the roof. This means cleaning it. Any debris or dust that remains could potentially weaken the membrane’s adhesive.

The whole point of the EPDM membrane is that it needs to be able to stick to the roof’s surface.

Gutter Inspection

The next step is to inspect areas of your roof with gutters. In these spaces, you may need to install a batten to extend your roof towards the gutter.

This will direct rainwater drips to the gutter instead of behind it, preventing damage to the supporting wall and fasteners underneath the gutter itself.

Secure Flashing

Make certain that you prepare the areas of your wall that would accept flashing—this redirects moisture from the wall towards the rubber membrane—and remove any excess brick mortar using a mortar chisel.

This will ensure that the flashings attach properly.

Apply Rubber

Lastly, prepare and install the rubber layer. Again, it is key that the rubber membrane bonds with the roof because this is how it seals and becomes seamless.

Apply the rubber to the roof evenly, and make sure to unfold the rubber after you have finished applying the adhesive.

This ensures it won’t dry out without attaching to the membrane. When you are done applying, cut away the excess rubber to complete the fit.

Final Thoughts on How Long Rubber Roofs Last

Rubber roofing is becoming more common due to its greater durability and lower installation costs. If you own a commercial building, you may want to consider installing a rubber roof to prolong its lifespan.

With proper installation and a favorable climate, a rubber roof can last 50 years.

4 Effective Options to Drain Your Commercial Flat Roof

One of the most common issues with flat commercial roofs is water accumulation. That’s why finding effective ways to drain your commercial flat roof is critical to its long-term health.

When water does not drain effectively, it pools up and damages the roof and underlying structure.

This can be especially devastating when there is damage to the façade of the roof. This means that water gets into areas it is not meant to be in (think leaks) and then permeates throughout the rest of the roof.

This can lead to additional water damage and potential structural damage that can be dangerous for the building and its inhabitants.

Thankfully, there are a few ways to ensure the water drains from your flat commercial roof, keeping it free and safe from potential water damage.

4 Options to Drain Your Flat Roof

Gutters
Scuppers
Interior Drains
Edge Drains

Gutters

Gutter systems, one of the most commonly used solutions, are also very cost-effective drainage solutions for flat roofs.

As the water rolls off the roof’s edge, gutters catch that rainwater and then divert it down into a downspout, which dispenses the water a safe distance away from the building’s foundation.

Ultimately, this prevents rainwater from rolling off the roof uncontrollably and running down the side of the building. Uncontrolled dripping can damage things like windows, siding, and even the foundation of the building itself.

However, there are disadvantages to using gutters as the primary drainage system on a flat roof. The first is that gutters need consistent cleaning to do their job effectively.

When debris, like leaves, builds up in the gutter, it blocks the flow of water. When the debris is not cleaned out, the water builds up and then overflows, running down the side of the building.

Gutters are also very susceptible to damage from ice, severe weather, and heavy debris buildup.

These are factors to consider when looking for drainage solutions for your flat commercial roof.

Scuppers

Scuppers are perhaps one of the most effective drainage solutions for a commercial flat roof. Using this system, large square openings are made along the edge of the roof, shooting the water safely away from the side of the building.

Downspouts can also be installed directly below the openings, which catch water and drain it away from the building in a controller manner similar to the gutters.

Flat roof scuppers also have several benefits. In addition to being cost-effective, they are much easier to maintain, meaning you won’t have to clean them as you would gutters.

Those wide, large scuppers will rarely get clogged by debris, and a well-designed scupper can even enhance the overall aesthetic of the building, making it look a little bit nicer than traditional gutters would.

Like anything else, however, downspouts have downsides. If you install the downspouts above, they risk getting clogged, requiring regular checks for debris buildup. They can also be quite ineffective for heavier snowmelt and rain.

Also, scuppers tend to be less effective on a flat roof with no pitch to guide the water to the edges of the building; the scuppers have to be somewhat cleverly designed to have the best overall effectiveness.

Interior Drains

These are similar to how the drain in your sink or shower might work. These drains would be placed in the roof areas where the water will most likely build up.

The interior drains would then lead the water through a system of pipes installed below the roof. The water would travel through the pipes until it was dispensed into a gutter or downspout on the side of the building.

Using an interior drainage system has some notable benefits. The first is that the walls and foundation of the building are protected from water damage.

The second is that the pipe system is protected from damage by the roof and walls, reducing the chances of freezing or cracking.

Lastly, this type of system is highly customizable, so you can get the exact kind of system you want.

There are downsides, however. This is the most expensive option due to the nature of the installation and customization.

Additionally, any damage that does occur must be repaired by a professional roofing technician.

Edge Drains

Edge drains work just as they sound: they sit at the roof’s edge and collect the water there.

It operates very similarly to a public shower. Scupper drains are similar in that the goal is to prevent water from running down the side of the building and causing additional damage.

Edge drains are a simplistic way to divert water from running down the side of the building.

They point the water to a predetermined destination so that it can drain safely away from the building without causing any damage.

Final Thoughts on Flat Roof Drains

Whatever the solution, drains are necessary for the life of your roof. If left unchecked, water buildup can lead to substantial issues over time.

Failure to address water pooling on your flat roof system often leads to serious and expensive consequences.

As a result, be sure to get your drainage system in place and ensure it works correctly.

What is The Lifespan of a Commercial Roof? (Updated for 2023)

Key Takeaway

The lifespan of a commercial roof is between 10 and 40 years, with factors like climate and installation quality impacting its longevity.

The roof is one of the most overlooked yet essential portions of your commercial building. When it is working as it should, it is out of sight, out of mind. But when there are issues, you can’t help but notice them and nothing else.

Knowing how long you can expect your commercial roof to last can help you prepare for repairs or a replacement instead of operating out of panic. Roofing replacement or repair can cost quite a bit of money and is something that can be catastrophic without properly saving and planning.

How Long Should My Commercial Roof Last?

This obviously cannot be answered as several factors can play into the life of a commercial roof. It depends on when the roof was installed, how it has been maintained, what materials were used, the weather in your location, and other factors.

Generally speaking; however, a commercial roof can be expected to last anywhere from 10 to 40 years. Here are some of the materials that are typically used in the construction of a commercial roof.

How Roofing Materials Impact Longevity

While this isn’t the end-all, be-all list of materials used, these are the most common commercial roofing materials that are used and their expected lifespan:

Ethylene propylene diene terpolymer. This is known as EPDM and can have a lifespan in the range of 22 to 35 years.
Thermoplastic polyolefin. This is known as TPO, with a general life expectancy of 22 to 30 years.
Metal roofs have a general life span of 30 to 45 years.
Polyvinyl chloride. This is known as PVC and carries a life expectancy of 20 to 30 years.
Asphalt roofs have a life expectancy of 20 to 40 years.

The materials are just one aspect, though. Other factors play heavily into the life expectancy of a commercial roof.

Other Factors That Influence Commercial Roof Lifespan

When installing a commercial roof, these are just a few of the factors worth considering, as they can each play a large factor in the life of that roof. Again, these are based on expected life spans and are by no means a science. You could have all of these factors, and your roof could be fine for 40 years.

Slope

When you have a flat roof, it is far more likely that water will pool on the surface; this is just gravity at work (or not at work, in this case). When the water doesn’t flow down the roof and onto the ground, it will find its lowest point and stay there until it evaporates.

Low spots are often where the damage starts, and leaking is often the first sign of damage.

Installation

The installation process is perhaps the most important step. This is because any flaws that occur during the installation process can ultimately shorten the life span of any roof. It is essential that when you need a new roof installed that you choose a contractor that is reputable, well-qualified, and experienced.

Don’t automatically look for the cheapest option; it can be worth it to shell out a few more bucks to ensure that you get the necessary work done.

Ventilation

The attic space that lies just underneath the roof itself needs proper ventilation. This ventilation is key because it helps prevent moisture and heat build-up. This is especially important during the summer months when the hotter temperatures in the attic space and up on the roof will essentially bake the roofing materials.

That built-up moisture can ultimately lead to mold and rot, which can cause a whole other list of problems for your building.

Maintenance

Though it may seem like a huge hassle, routine maintenance and inspections on your roof can prevent those small problems from becoming far larger. It can be easy to neglect your roof, especially when there are issues.

It is imperative that you do not, under any circumstances, ignore those problems. They can lead to huge issues that can make your commercial building unsafe to be inside.

Weather & Climate

This is one of those factors that you kind of can’t help. Depending on the area that you live in, your building might be susceptible to higher winds, hail, heavy rains, or heavy snow. This kind of exposure to the elements can wear on a roof over a long period of time and really cut down on the expected life of a commercial roof.

Final Thoughts on Commercial Roof Longevity

When there are issues regarding the condition of your commercial roof, it is important to have a dependable roofer available. When there are issues with the roof, it can lead to huge problems and structural damage to the rest of your building. This is why it is important that you never, ever ignore problems that might be occurring with your roof.

The life of your commercial roof depends on all of the factors outlined above, each one having its own individual impact when it comes to the life of your commercial roof. Even though you can’t help things like weather and time, preventative measures can be taken to ensure that your commercial roof enjoys a long-lasting life. You can even take preventative measures yourself by simply checking your roof every once in a while to see if there are any leaks or damaged areas that might need attention.

The roof can feel like a hassle, especially when you know that there may be something wrong, but make sure that you take those steps to inspect the overall health of your roof. It is something you will be thankful that you did over time when you extend the lifespan of a commercial roof and hit those huge milestones instead of having to be replaced entirely.

Hail Size Roof Damage Chart

When a storm rolls through your town, there are a lot of things that can do damage. Heavy winds are the usual culprit, but hail is another type of storm that can do significant damage. The most recent annual data estimates over 3,700 hail storms in the United States.

After these storms, it’s handy to have a hail size roof damage chart at your disposal, like the one below:

Key Takeaway

Any hail larger than a ½ inch can damage a roof, meaning ¾-inch to 1-inch hail (quarter size) and 1 ¾-inch to 4 ½-inch hail (golf ball size) should prompt a call to your insurance company.

Assessing Roof Hail Damage by Size

When hail grows in size, you can be concerned about things like your car or, even worse, your roof. The costs can be heavy when there is damage to your roof. Even minor damage can cost thousands of dollars, and most of us do not have that kind of money lying around.

They say they are there for us when disaster strikes, but most insurance companies will find any reason not to pay out a claim. After all, it is how they strengthen their bottom line.

When hail becomes a concern, it can help to know what size hail can damage your roof. Again, not all hail is worth worrying about, but when those bigger chunks begin to hit, you can wonder what to do. Inspecting your own roof is dangerous, and you may not know what to look for.

Most people won’t be able to manually measure hail during a storm, so you can estimate using common identifiers like “golf ball size” and “marble size.”

Understanding which hail sizes can damage your roof gives you a good idea of when to call in an inspector to check for damage on your roof. Here are a few of the most common hail sizes that damage roofs nationwide.

¼-inch Hail (Pea-sized Hail)

Milder hailstorms generally produce this size of hail, but only for a few minutes at a time before it shifts over to steadier rainfall. When dealing with this size of hail, a roof can often fair pretty well.

Use some common sense and judgment before jumping to any conclusions.If you have an older roof with existing damage, pea-sized hail could exacerbate the present damage. Be aware of the condition of your roof before judging whether it needs an inspection after a hailstorm.

½-inch Hail (Marble-sized Hail)

Marble-sized hail can also fall into the safe zone when it comes to hail, meaning it generally doesn’t cause damage to roofs that don’t already have substantial damage.

Remember that hail is produced by updrafts of wind that shoot raindrops higher into the atmosphere. It freezes when it gets higher into the atmosphere and then falls back to Earth.

When you have more extreme winds, the hailstones will generally be larger. While the quarter-inch-sized hailstones might not be of much concern, exercise caution and common sense again.

If you have any thoughts that there might be damage to your roof, call in an inspector immediately.

¾-inch to 1-inch Hail (Dime to Quarter-sized Hail)

You should call an inspector immediately when you see hailstones larger than the ½-inch described above. Finding a reputable local roofer is a great place to start, and you also need to make sure that you place a call to your insurance agent.

Hail this size generally damages roofs in the form of dents and cracks, though in some cases, it can definitely cause greater damage.

Do not leave this unaddressed. As expensive as it can be, if you leave the damage unaddressed, it could become a more expensive, extensive, and potentially dangerous condition to live in.

In any event, you must talk to your insurance agent immediately. Knowing what your policy covers and what might be paid for can help you determine your budget and which contractor to use.

Part of the headache of dealing with damage to your roof is dealing with the insurance company; try to get that duck in a row as soon as possible.

Once hail size approaches 1 inch, you will most certainly have roofing damage of some form. It’s important to contact your insurance company as soon as possible.

1 ¾-inch to 4 ½-inch Hail (Golf Ball-sized Hail)

While not an uncommon hail-size range, golf ball-sized hail can still substantially damage your roof, car, and home. Like with dime-size hail, you should contact your insurance agent by phone to discuss your options.

Agents might send a roofer to determine the overall damage before proceeding. Your policy may cover a portion of the damage your roof sustained.

Hail can be a nasty beast, even if it only occasionally rears its ugly head. Whenever there is hail in your area, you must assess the size of the hailstones first and foremost. Under ¾-inch, you are probably fine unless your roof already has substantial damage and age.

Anything larger than 1/2 inch should prompt you to discuss the next step with your insurance agent and find a roofing contractor to inspect your roof.

The Bottom Line for Roofs With Hail Damage

Being calm and knowing the steps to take when a hailstorm hits your area can make all the difference in the world when trying to get the necessary repairs done.

The key is not to panic and not jump to conclusions. Make sure that you take all of the proper steps so that you can not only get your roof repaired but get it done in a cost-effective way.

Because hail damage leads are often hot items for roofers, cities recently hit by storms will be ripe with them. Be aware of whom you’re dealing with.

If you are unsure whether or not your roof was damaged by a hail storm, getting an inspection is the best option. Even if the hail is around 1/2 inch in size, it can exacerbate existing problems with the roofing system.

When hail is larger than 1/2 inch, including quarter and golf ball size, your roof is almost certainly in danger. The more quickly you address damage from hail storms, the less future complications arise.

The Importance of Commercial Roof Washing & Cleaning

Commercial roof washing is one of the most essential investments in your building’s long-term safety.

Even durable commercial roofs benefit from regular cleaning and washing.

The following post explains why commercial roof cleaning matters and how it could impact your monthly expenses.

Remember, not all commercial roofing systems are healthy enough to receive a thorough washing.

If you suspect your structure has sustained serious structural damage, it might be time to talk with your local contractor about a commercial roof replacement before investing in a cleaning.

Key Takeaway

The cleaning process can extend your roof’s lifespan, enhance building appeal, and prevent minor damages that lead to repairs.

Commercial Roof Cleaning Explained

Roof cleaning is the process of removing debris, trash, algae, and other forms of growth from the surface of your roofing system.

Depending on the type of roof and material involved, a commercial roof cleaning may entail pressure washing or even chemical treatment.

Ultimately, the goal is to leave a clean, vibrant surface after the project.

While some retail products may temporarily relieve some of your commercial system’s many threats, a seasoned professional is more likely to provide the long-term results you desire.

Threats Against Your Roofing System

Years of exposure can leave any roofing system vulnerable to natural hazards. For metal roofing systems, rust slowly eats away at the metal panels, weakening the integrity of the affected areas. Plus, it just looks terrible!

Other roofing systems suffer from dirt, mold, and algae. Not only do these elements create an unsightly smear on your beautiful roof, but they can also speed up the process of long-term degradation.

If mold and algae get sucked into the building’s heating and cooling system, your employees could experience some unpleasant side effects.

Finally, removing all the debris also reduces the potential for ponding water, one of the most dangerous threats to flat roofing systems.

While rooftop debris may not be an immediate concern, it represents a significant threat to your roofing system in the long run.

Algae present a significant threat to discolor both Flat and sloped commercial roofs.

Key Benefits of Roof Washing

Renewed Efficiency

What image comes to mind when you think of TPO, PVC, metal roofing, and other cool roofing systems?

If a brilliant white or silver roof springs up, that’s certainly the right picture! Over time, dust, dirt, mold, and algae accumulate on the surface of your roofing system. This darkens the membrane or metal.

Darker surfaces naturally absorb more light, causing the rooftop to heat up and conduct heat toward the building interior.

That’s the typical process of heat gain that so many businesses (and air conditioning systems) struggle with daily.

By washing away the murky grime from the surface of your flat or sloped rooftop, commercial roof cleaning renews the reflectivity and restores efficiency.

Regular commercial roof washing keeps your metal roof reflective while preventing dirt accumulation.

Commercial Roof Cleaning Over Metal Panels

Over time, regular roof cleanings save you money on costly repairs.

A Cleaner, Healthier Environment

Sometimes, cleanliness is its own reward. In the case of many businesses, however, a moldy rooftop may actually violate local health codes and put the business in jeopardy!

No matter what industry you work in, protecting your building from the terrible smell of long-term mold growth makes sense.

Those particles can get drawn in through the building’s AC unit and start circulating inside the building.

Talk with your local roofing contractor if your community deals with regular algae or mold growth. You may require a special chemical cleaner to protect your rooftop.

A Close Look at Your Roof Surface

Dirt and other smudges tend to obscure more serious problems beneath.

A clean rooftop is much easier to inspect for surface-level degradation, such as…

Exposed and/or weakened seams
Puncture marks
Deep scarring
Brittle spots
Depressed areas

Identifying these problems early on could prevent all kinds of problems. Finding a weakened seam, for instance, could prevent hundreds of dollars in future water leaks.

Preventing a system-wide problem could even save you thousands of dollars and an early roof replacement!

Sometimes, a roof cleaning reveals underlying problems, saving you from expensive repairs or replacements.

Roof washing often reveals brittle spots and puncture marks.

Find Your Commercial Roof Cleaner

Commercial roof cleaning is a common requirement for businesses with upcoming repair or restoration projects.

For some, however, it’s simply a prudent investment to avoid the unpleasant effects of algae growth, mold smell, or diminished energy efficiency. Timely maintenance can make all the difference.

Finding a commercial roof washing service can be a challenge in some areas.

Make sure you evaluate the company’s reviews on Google My Business, Yelp, and other reputation platforms. Also, check out their website for examples of previous commercial roof cleanings.
