I have spent a lot of time discussing RV roofs. The reason for this is all of the misinformation about repair them. I would like to warn all RV owners that when you repair a EPDM RV roof that you use a product that is compatable and meets warranty requirements. Most of the repair products on the market are not what the manufacture sugguest and could void the roofing warranty. So be sure to check and make sure. It could save you a lot of money in the future.
