I am a new RV owner of a class A gas Winnebago. I understand that I need to re-seal the roof each year and my coach has a nice clean ceiling inside and I want to keep it that way. Is sealing the roof something that I can do? Is it fairly simple and is there a video or something that shows how to do this?
First you need to figure out what kind of roofing material you have. Common materials are, EPDM, TPO, & fiberglass. All have slightly different maintenance requirements and materials. If your roof is a rubber like material then most likely is EPDM or TPO. To figure out what you have take the bottom cover off of a roof vent and look at the bottom of the roof material. If it is the same color as the top it isTPO if it is black it's EPDM. All roofs need to be kept clean. On EPDM & TPO roofs don't use any cleaner or sealant with petroleum distillates. TPO you can use any mild cleaner with EPDM I only used the specialty EPDM cleaner and sealer. For the seams I use Dicor self leveling sealer. I also am a fan of Eternabond. Whatever you use carefully look at the seams for cracks, deterioration, or bubbles. Clean the area carefully and reseal. In general I don't remove old sealant except if silicone or loose sealant. Bottom line get up on the roof and get to know your roof.
