9 Outstanding Benefits of A Butyl Elastomeric Roof Coating

Butyl Elastomeric Roof Coating (Blog Cover)

Butyl elastomeric roof coating is one of the most versatile options for commercial roofing systems. That’s because you can apply it to almost any kind of substrate. It’s also incredibly flexible because of the rubber content in the composition. That’s why you see these types of roof coatings on many commercial and flat roofs across the United States. 

But what are the specific advantages of butyl elastomeric roof coating? Are there any kinds of roofing systems that aren’t good candidates for it? As a property owner and roofing contractor, these are the crucial questions you must ask yourself. And in the following post, Roofer’s Guild will help you answer them. 

Butyl Elastomeric Roof Coating Basics

Before we go any further, you should know that butyl elastomeric roofing is sometimes referred to as simply butyl rubber roofing. Again, this is because of the elastomeric rubber that makes up the composition of this type of roof coating. 

The coating is applied as a liquid. As it cures, it hardens to form a single, continuous membrane that acts as a complete coating for the roofing system. 

But maybe you have heard of butyl rubber in other products and wondering if it is the same material. The answer is yes. Butyl rubber is a very versatile material. It is used to make many products, including lubricants, cling film, fiber optic compounds, adhesives, rubber gloves, and much more. 

It is used primarily because of its flexible qualities, but it is also solid and resilient as a rubber product. 

Frequently, you will find that butyl rubber is used to make a wide variety of industrial-strength products, such as butyl rubber gloves. Its industrial use speaks to the strength and reliability of the material. In addition, it highlights why it’s trusted to coat roofs across the country. 

Butyl Elastomeric Roof Coating Benefits

Will a butyl elastomeric roof coating be for everyone? Certainly not. There are certain things you will have to take into careful consideration before choosing butyl elastomeric as your roof coating material.

For instance, consider your roof’s size. Butyl elastomeric is comparatively affordable, but it is undoubtedly more expensive than other types of roof coatings. So if your commercial property has a larger roof area, the project could exceed $3,000. 

Butyl coatings are not the most expensive option, but you will still have to be able to fit them comfortably within your budget. If you can, though, here are some of the essential benefits of butyl elastomeric roof coating:

1) Extreme Versatility

One thing that will not prevent your roof from being a good candidate for butyl elastomeric coatings is the substrate. One of the best things about this material is that it can be applied to virtually any substrate, including metal, concrete, built-up roofing, single-ply roofing membranes, and modified bitumen.

2) Excellent Leak Protection

While not exclusive to butyl elastomeric roofing, the single continuous membrane structure provides excellent leak protection for most roofs. In addition, the security includes ponding water prevention which can be detrimental for some roofing systems. 

Ponding water can often cause roof sagging and, eventually, leaks. Butyl rubber is incredibly leak-resistant, even in the case of pooling water. 

3) UV Reflectivity

Butyl elastomeric roof coatings can come in white or light colors that are very effective for reflecting the sun’s UV rays. The more UV rays you reflect off your roof, the lower your cooling costs. Installing a complete butyl elastomeric roof coating on your roof can save you hundreds or thousands of dollars on your annual utility bills. 

4) Thermal Cycling Resistance

As the temperatures fluctuate outside, your roof is subject to a cycle of expanding and contracting. While natural, this thermal fluctuation takes a real toll on most types of roofing material. Years of contraction and expansion could cause cracks in the roofing system. 

The rubber content in butyl elastomeric makes it very flexible. As such, it stands up much better to thermal cycling than other roof coatings. 

5) Ease of Installation

This benefit comes with a caveat. In theory, butyl elastomeric roof coatings should be easy to install. That’s because it is applied as a liquid and sprayed onto the existing substrate of a roof. 

However, contractors should note that the solvent-based material can be challenging to work with unless your spray equipment is clean and maintained well. On the other hand, if you do maintain your spray equipment well, the application should be no problem.

6) Flexibility

The flexibility of the cured butyl elastomeric coating is advantageous for many things. But one of the best things about it is its flexibility makes it ideal for foot traffic. It is not a rigid roofing material that will break under a footfall. 

Suppose your building maintenance often involves service workers on your roof (servicing HVAC systems, repairing lights, electrical issues, skylights, etc.). In that case, you may want to consider butyl elastomeric roof coatings.

7) Multi-Utility

Up to now, we have primarily spoken of butyl elastomeric roofing as a complete roof coating. And while it is used in this way a lot, it’s not the only way it can be used. For example, because it is a spray-on roof coating, it can also be used to repair leaks. 

This type of roof coating can be used as something like a patch material for when you need spot repairs on your roof. In this way, butyl elastomeric is a very affordable way to repair your roof.

8) Longevity

Generally, a butyl elastomeric roof coating can last between 10 and 20 years. However, you should also be aware that how long the roof coating lasts may depend on the application’s thickness at the installation time. 

For example, you can reasonably expect your butyl elastomeric roof coating to last 20 years or more if about 0.03 inches of it was applied to your roof. Of course, maintenance and the quality of installation will also play a hand in the roof coating’s longevity. Still, a thick layer can provide you with long-lasting roof protection.

9) Warranties

Most roofing contractors offer good warranties on their butyl elastomeric roof coatings. That’s because it is a durable and reliable roofing material. Generally, you can expect your roofing contractor to offer a warranty between 10 and 18 years for a new butyl elastomeric roof coating. 

Final Thoughts on Butyl Elastomeric Roof Coatings

As a roofing contractor, you work hard to provide outstanding services to your customers. That’s probably why you are interested in butyl elastomeric roof coating in the first place – it’s a high-performance roofing system that could benefit many of your customers.
