How Long Does Elastomeric Roof Coating Last?

by | Aug 27, 2022 | Roof Maintenance

When looking at improving your home’s look and value, upgrading your roof is a quick fix. Plus, a better roof will have increased functionality to your home. However, most homeowners don’t consider improving their roof until it’s too late. That can be from a leak, falling shingles, or fading roofing materials.

One proactive roofing choice is adding elastomeric roof coating. In this blog, we’re going to discuss elastomeric roof coating, its purpose, and how long it lasts.

What Is Elastomeric Roof Coating?

Elastomeric roof coating is a fluid-applied coating. You can apply it by spraying or back-rolling it directly onto an existing roof. People typically add elastomeric roof coating onto a roof that’s in good working order, and possibly when the warranty is about to expire.

This coating is about ten times thicker than standard paint. So, elastomeric coating is waterproof, has more solids, and is more durable than paint. Applying elastomeric coating is an excellent addition to any roof. You’ll notice immediate results, both visually and physically.

Benefits of Elastomeric Roof Coating

You might be thinking that elastomeric roof coating sounds too good to be true, but that’s the catch: there is no catch. The coating has several benefits. It helps prevent UV damage, reflects the sun’s light depending on its color (as opposed to a black roof), and easily seals cracks and holes.

But the list goes on. An elastomeric roof coating is more affordable than completely tearing off and redoing your roof. This coating is just maintenance as opposed to adding another roof layer; making its process more simple. You get one seamless, monolithic waterproof roofing sheet.

So, How Many Years Does Elastomeric Roof Coating Last?

Maybe you’re sold on the benefits and purpose of elastomeric roof coating, but there’s one more thing you’re curious about. How long exactly does elastomeric roof coating last? Most elastomeric roof coatings last between 10 and 20 years.

We recommend having an inspection of your roof before applying the coating, because this is a significant factor in its lifespan. Other factors that affect how long the coating lasts include exposure to sunlight, external damage, and initial application thickness. Luckily, you can have maintenance and minor repairs to your elastomeric coating as needed. With professional help, you can keep your roof in excellent condition and have the coating last up to 20 years.

Types of Elastomeric Roof Coating

While elastomeric roof coatings are good, there’s a few intricacies behind the coating options. The types include butyl, acrylic, polyurethane, and silicone.

Butyl has good flexibility and withstands ponding on low-slope roofs, but it can be harsher on the environment when disposed of. Acrylic coatings are highly durable and often used with better drainage roofs, but they do not withstand ponding as well. Polyurethane is the most durable, which makes it an attractive choice for any roof that will have high foot traffic; but it’s not great for novices applying it themselves. Lastly, silicone can be highly UV resistant and withstand ponding well; yet, they can erode faster than other choices.

Elastomeric Roof Coating Cost

Of course, any roofing cost will depend on the roof’s square footage. However, most residential roofs range between $1,000 to $2,000 for an elastomeric roof coating, whereas commercial roofs cost between $1,500 to $3,000.
