A Beginner’s Guide to Elastomeric Liquid Roof Coatings

When was the last time you inspected your RV’s roof? If it wasn’t recently, you might be in for a nasty surprise. Over a year, your RV’s roof puts up with a lot of wear and tear, and unless you’re just a cautious personality, it’s easy to forget about the roof. But if your roof has gone without maintenance, holes and cracks may have set in, or the seams have begun to give way. This means water could be leaking in, causing electrical and structural damage that will leave your RV in a pitiful state.

If your roof has been damaged, you’ll need to get it repaired pronto. If not, you should consider extending the life of your roof by adding an elastomeric liquid roof coating. That’ll help protect and seal the roof and slow or halt any more wear and tear. If you’ve never heard of elastomeric roof coatings, no sweat; we’re going to go through everything you need to know to help protect your RV’s roof.

ElastoWho Roof Coating?

We appreciate that elastomeric roof coatings aren’t your average conversation topic at the office water cooler or family meal. Unless you’ve done your research beforehand, this might be the first time you’ve heard about this type of coating. In a nutshell, an elastomeric roof coating is a layer of elastic that you apply to a roof to help prevent leaks and add a few more years of life to your roof.

Compared to other roofing materials, they’re flexible and move with the roof, which makes them a great addition to your RV. Flexibility also equates to durability. You don’t want something that’s overly rigid on top of your RV because it will crack and shatter much faster than a stretchy and flexible elastic coating. They can be applied to metal roofs, concrete, EPDM roofs, BUR roofs, or even a general sealant.

When to Restore Your Roof

Ideally, you want to apply an elastomeric roof coating as soon as you start to see some age set into your roof. Getting to the problem before it has time to worsen or spread will keep you from having to make a pricey total roof replacement. The longer you leave it, the more expensive your problem will become. Compared to the price of an elastomeric roof coating, a new roof will set you back about four times more—an expense that can easily be avoided.

How It Works

The overall effectiveness of the coating will come down to your roof’s current condition, so a roofing expert will first inspect your roof for any damage or weathering. If there are already leaks or holes, you’ll first need to have those repaired. Once your roof is ready, they will spray a primer to prep the surface, seams will be reinforced, and then the coating will be applied using a sprayer or roller in one clean, seamless layer. After the surface dries, your roof is sealed and protected for years to come!


Before you hit the road for your next RV adventure, it’s crucial that you first inspect your roof. You don’t want to find out you’ve got a serious leak 300 miles from home. But if you find a few signs of aging, it’s nothing to worry about. Rather than installing a whole new roof, consider applying an elastomeric roof coating. It’ll put years back into your RV without too much hassle and save you the cost of a new roof in the long run.
