Elastomeric Roof Coating Explained

With all the advantages out there when it comes to roof coating, it’s understandable that you may want more information before making a decision. Your roof is important, after all, so anything but the best is taking a pretty big gamble. Keep reading to learn more about one option, an elastomeric roof coating.

What is an Elastomeric Roof Coating?

An elastomeric roof coating is one that greatly resembles rubber once it’s applied. One of the main advantages of this particular form of coating is that it can be applied to so many different kinds of roofs.

What are Its Advantages?

There are many benefits to choosing an elastomeric roof coating. As mentioned above, it can be used on just about any surface type. This includes roofs made out of metal, single-ply applications, built-up applications, modified bitumen, and much more. It can even be applied to freshly sprayed polyurethane foam.

The actual angle of the roof doesn’t matter, either. Unlike some other coatings that can only be used on buildings with a flat top, elastomeric coatings can handle those and ones with just about any type of slant to them.

Once applied, an elastomeric roof coating will provide superior resistance against just about any weather condition. As it acts much like rubber, it can stretch when the temperature goes up and then retreat to its original shape when it gets colder out. By doing this, it resists cracking.

Because of the strong seal this coating produces, it’s great for energy efficiency. Cold air and heat stay in, while the outside world is kept at bay.

There are four main types of elastomeric coating. They are as follows:

Acrylic Elastomeric Coating

This is the most widely used elastomeric roof coating. It’s great for roofs with a positive slope, for one thing. It also displays superior longevity and is easy to clean. Furthermore, many people appreciate that it is considered an environmentally friendly option.

Butyl Elastomeric

For flat roofs or those with a low slope, butyl elastomeric is a great choice. It works especially well on roofs that are made from modified bitumen, asphalt built-up, or singleplied roofing. One advantage for flat roofs is that this variety can resist the pressure of pooling water.

Polyurethane Elastomeric

While EPDM roof coatings are considered high quality, adding a polyurethane elastomeric coating will further help ensure the roof’s overall protection. This variety is also especially good for roofs made from modified bitumen or a single-ply application of PVC or TPO.

Silicone Elastomeric Coatings

This is a great option for a roof that was recently treated with polyurethane foam. The main reason is that a silicone elastomeric coating displays excellent weathering. Whether the foam was just recently sprayed or needs a new layer for protection, this is a great choice.

When you’re looking to coat your roof for added protection, it’s hard to think of a better option than the rubber-like elastomeric coating. It can be applied to just about any surface, and it will display excellent durability while adapting to weather conditions. With several different options to choose from, you can find the coating that will work best for your roof.

  1. I am looking for an elastic paint that will be able to topcoat an EPDM roof liner on a fifth wheel. The EPDM liner i have is starting to break down to the point that the roof is tacky in some places.

    • Hi David sure that would be our rvroofmagic it is a one coat system and does not need a primer. here is the real difference between our product and others The science behind our product Chemical cross-linking

      When we discuss “crosslink” it is really the process of our product forming a sequence of chemical bonds to join two polymer chains together. An object made of a cross-linked rubber is one single molecule. Ours which is an oxidative meaning it undergoes a proprietary cross-linking process when exposed to oxygen. These crosslinks tie all the polymer molecules together making them very strong, enhancing tensile strength and decreasing overall product degradation over the years.

    • Hi paula the product works on almost all roof types without the need for a primer particularly EPDM give our office a call and we can help with what you need on the repair of the seams as well. Our number is 610-298 1989 ext 9
      Thank you
