Caulking

[Carl & Patti]

Well, it appears as though my 2017 36RL is in need of caulking. I would like to go on record as saying I hate to do caulking. That said, I wanted opinions about the type of caulking I should use at the point where my roof meets the gutter.. I have both Geocel ProFlexRV in Clear (GC28100) and Dicor Cap Sealant (351CST-1) in Tan. I believe I have a TPO roofing membrane. In the back of my my mind I seem to recall from one of the RV rallies hearing that we were not to use Dicor products on a TPO roof. At the point where the roofing meets the gutter is it the same material as the roof itself? It is a rough material where the roof itself is smooth. Don’t know if I explained myself very well.

First to determine which type of roof you have watch this video put out by Dicor. They will show you two ways to determine which type of roof. Then look at their how to videos on how to seal the roof and what to use. Hope this helps.
