EPDM roofs are actually ideal, and very easy to protect. Use of treatments that protect roofs is really not required, as the EPDM is already self protecting. In fact, all you need to do to make it last as long as possible is to clean it regularly. It’s recommended that you clean an EPDM roof four or five times each year.
If your rubber trailer roof is more than a few years old, you may well notice a chalky build up on the surface of it. Don’t worry about this; it’s just normal deterioration due to aging that is unavoidable. If you clean your roof often, you will minimize this chalky build up anyway, and it will visibly reduce the white streaks that can be seen on the sides and roof of your RV.

Asphalt based aluminum coatings should be removed as much as possible by wire brush or abrasive disc. Roof cements should be removed and replaced with butyl caulk where necessary. Repair torn rubber with adhesive Butyl Tape. EPDM rubber patch may be applied over torn area if desired.
