What You Need to Know about Liquid Roof RV Repair

RV roofs are interesting things. They have to be lightweight enough for the application, but they also have to be strong enough to withstand heat and cold, sunlight and rain. One of the most commonly used materials for RV and travel trailer roofs is EPDM – a lightweight, waterproof rubber. It’s usually mixed with fabric, and can be easily confused with fiberglass. However, EPDM can be damaged, and you’ll need to ensure that you do it the right way.

Preparing Your Roof

The first step to in liquid roof RV repair is to prep the area. Of course, before you can do that, you’ll need to locate the source of the leak. This is usually much easier on an RV or trailer than it is on a residential home, but it can still take some time. If the source of the leak isn’t obvious (a puncture or similar damage), check your seals, as they can degrade over time and pull apart, allowing water into your RV’s ceiling.

Once you’ve located the leak, you’ll need to prepare the area for EPDM liquid roof for RV use. The container of EPDM sealer should provide explicit instructions on how to prep the area to ensure the best adhesion with the new layer of EPDM you’ll create when applying liquid roof to your RV. Usually, prep will include:

  • Thorough cleaning
  • Removal of any debris
  • Sanding (lightly)

Make sure you have the right tools for the job, as well. Generally, you’ll need a roller or brush to apply the liquid rubber, but you will also likely need a good scraper for removing EPDM from around the damaged area, as well as sandpaper for preparing the area.

Applying Liquid Roof to Your RV

Before you begin applying liquid roof to your RV, you’ll need to read the directions. Most applications require little more than using a brush or roller to apply the liquid rubber and then allowing it to dry thoroughly before applying the next layer. You will need more than one layer. Make sure you allow enough time for the first layer to dry before you apply the second coat.

The total drying time will vary based on several different factors, including the thickness of the coat, the humidity, the presence of direct sunlight, temperature and more. Generally, liquid rubber will begin setting immediately, particularly in hot conditions and in direct sunlight. For the best results, most manufacturers recommend not applying the rubber when the roof of your RV is already hot. A temperature of about 70 degrees is optimum.

Doing It Yourself?

Not all RV owners are DIY-minded. If you’re not really all that gung-ho about repairing your RV’s roof on your own, work with a reputable repair provider that understands the ins and outs of dealing with EPDM and offers liquid roof RV repair services. Not all repair centers offer liquid roof repair with EPDM coating, so compare your options and choose the right pro.
