Quick Guide for DIY RV Roof Repair with EPDM

If you’ve got an RV roof repair project ahead of you, then it is imperative you have the right materials on hand to get the job done. It’s a well-known fact that without the right materials, your repair is bound to fail and leave you back at square one. A common product used for RV roofs and repairs is EPDM. The product is a very durable synthetic rubber material that acts as roofing membrane. By definition EPDM stands for ethylene propylene diene terpolymer.

It’s very typical to find EPDM used on buildings and structures with a low slope. If your RV has EPDM then you’re in luck because the repair process will be relatively simple and smooth, not to mention fast.

Going About the Repair

You’ll need a variety of materials in order to re-seal a rubber or metal roof with EPDM. First you’ll need a scraper or joint knife, a razor knife, a cleaning agent specific to the job, and an EPDM roller. Now you don’t want to go cheap on your tools as they will help to determine the quality of the repair job. Of course you will also need to pick up and EPDM primer, as this is widely recommended to be used first before applying the EPDM. It will make sure that the bonding process is smooth and solid. It’s also great for roofs that are quite aged, and are no longer in great shape.

Now that you’ve got your tools and materials it’s time to get started. Cleaning the roof is the first step in the process, and this doesn’t mean just a general surface clean. You’re going to need to remove all dirt, debris, and grime. A power washer can be helpful during this step. If you are using a cleaning product be sure that it is safe to use with an EPDM surface and that it won’t damage it. Next it’s time to scrape away any old caulking that is peeling and/or coming off. You want a fresh clean surface to work with.

Once you have achieved a nice clean slate it’s time to apply a coat of the EPDM primer to the area. Make sure you let the primer dry completely, and then you can move on to applying the EPDM adhesive and the EPDM membrane to the area.

These steps work well for small patch jobs and larger jobs. Just be sure to follow all the steps and be thorough with each. In some cases you may need fasteners to secure the area.

The Lifespan of Your Roof

Often people wonder what the lifespan is on their RV roof. Although EPDM is said to last up to 20 years, typically 10-12 years is more often the case. This is still a good chunk of time, so knowing how to do small repairs can certainly increase its overall lifespan.When it comes to the repairs you can take on yourself, small leaks, tears, rips, and punctures are completely manageable on your own.
