Hi,
I am in the process of recoating my roof right now. The original roof was coated at 15 years old, and now is 18 years old. The coating did not last to well, and I suspect that it is because I did not prep most of the roof by cleaning it really well before coating it.
Where I had put on the coating really thick, and cleaned that area well before coating it, that section was still in good shape, and not able to pull it off. Other areas had thin coating and scrubbing the dirt off tonight with a washcloth and try with a towel would peal some off, leave some behind.
That coating was Herculiner, a bedliner, and it was recommended by the manufacture for 101 things to apply it to, including RV roofs. My hope was it would be tough to branches, and not slippery, and it meets both those needs. However I did hope it would last more than 3.5 years!
This time I am coating the roof with a RV roof coating. I recommend coating the roof before it is 10 years old, so that there is something for the roof to stick to. My roof is basically falling apart, due to the "Shedding" effect of a rubber roof. This keeps it looking clean (because it sheds dirt and EPDM both at the same time) yet the RV will have white streaks going down the side of it.
I don't have the contact info about the roof coating in front of me, but can get it. . .
Fred.
