Professional contractors can replace a roof in one day, barring unforeseen weather conditions or other complications. However, some roof replacement jobs are more complex and require longer estimated replacement times.
Like many things in roofing, the duration of a roof replacement is not universal. Several factors affect the possible timeline. Still, it’s an essential question on the mind of anyone who is considering or needs a roof replacement.
Of course, you want to know how long the job will disrupt your routine. You also want to know when you can start enjoying your brand new roof. Maybe you are prepping your home for the market and need to get the job done as soon as possible.
It’s critical to understand what affects the duration of a roof replacement job. But unfortunately, there is no universal answer to the question, “how long does it take to replace a roof?”
Average Roof Replacement Time
While every job is different, there is a general timeframe that an average-sized roof replacement will require. In general, the job should take a day or two. Of course, this assumes that weather conditions are ideal and the job is relatively basic.
However, you shouldn’t always expect this estimate from your contractor. And as a contractor, you need to be aware that something can happen at any time that will extend the project.
It would help if you always let your customers know that many factors could hinder the progress of a job. Of course, you always need to give a time estimate. Still, it helps to qualify it by letting the customer know that it is always subject to change given different conditions.
Variables That Impact Roof Replacement Time Frame
Calculating your roof replacement time frame is much easier when you understand which variables will impact the project. For example, are you replacing a roof on a house or commercial building? First, Let’s look at what can affect the time it takes to replace a roof.
The Size of the Roof
Naturally, the first thing you have to consider when providing a time estimate to your customer is the size of the roof. Residential roofs can vary significantly in size. Of course, a large estate will take longer than a single-family home if the roofs need replacing.
Commercial jobs generally involve larger roofs, so they take longer than residential ones, but that isn’t always the case.
The square footage of the roof will be an essential factor in determining how long it will take to replace.
The Structure of the Roof
If you deal with a standard, asphalt shingle-pitched residential roof, a replacement can take as little as one day. Roofs vary significantly in complexity as well, though.
The more complex the roofing structure, the longer it will take to replace. What do we mean when we talk about roof complexity, though? Take a look:
- Multiple angles
- Multiple Hips
- Multiple valleys
- Steep pitches
- Heavy roofing materials like slate
- Roofs with more than four facets
- The height of the roof
If the house or building in question has multiple facets, many hips, and valleys, or is made of natural stone material, the project could take up to three days or more. The basic rule is that the simpler the roofing structure, the shorter it will take to replace.
The weather is the next most prominent factor in calculating how long it will take to replace a roof. You cannot replace a roof in rain or snow. Even high wind conditions and temperature can halt a project dead in its tracks.
Why? Because in wet conditions, extreme heat, or freezing temperatures, roofing materials cannot be installed properly. They are subject to expansion and contraction depending on the temperature. It is impossible to replace a roof when it’s raining or snowing.
Most contractors will be cautious about when they schedule a roof replacement, so you don’t have to worry about it. However, you never know when the weather can change. In some unforeseen turns in the weather, the project will need to be halted. Weather delays could add days or even weeks to the completion time of the job.
If you live in areas with moderate climates, the weather won’t be of much concern to your roof replacement project. But it would be best if you were still very careful when you schedule your roof replacement and frequently check the forecast.
The nature and characteristics of the property will affect rood accessibility. When roof accessibility is limited or complicated by these characteristics, you can almost guarantee that the job will take longer to complete.
For instance, let’s say you are building your dream home on a rural piece of land you bought to get away from the city. Unfortunately, there may be no paved roads near this property, so it will be more difficult for contractors to transport roofing materials in and out of the property.
Let’s say you have a house in a traditional residential area with plenty of paved road access. Still, you have a hedge of bushes surrounding it. This can make it more difficult for roofers to get up and down.
Fences positioned close to the house can also make it trickier to get up to your roof. Your property and ease of roof access will affect how much time your roof replacement will take.
Last but not least, safety will determine how long your roof replacement will take. OSHA has stringent and specific rules for roofing contractors to protect their employees and consumers.
For instance, fall protection measures may apply to high roofs. In some cases, contractors may need overhead structures attached to them via cables to protect them from falling off the roof. You might need even more safety measures if your roof has a steep pitch.
Sometimes roofing safety measures don’t take much time. But you can expect longer replacement times if you have a roof that may be particularly dangerous to work on. In any case, a contractor should discuss all these measures with a customer before the project starts.
A standard roof replacement time frame is one day. However, many variables may add to the expected duration. For example, inclement weather, commercial building structures, or transportation restrictions can add more time to a roof replacement job. The most important thing is getting the job done correctly.
