XTRM Universal RV roof sealant
There are various types of RV roofs now being used: Rubber (EPDM), PVC and multiple formulations of TPO. Care must be taken to make sure that the roof sealant used, is compatible with your exact type of RV roofing membrane. To help alleviate that problem, LaSalle Bristol now offers the XTRM Universal RV roof sealant that can be used on all RV roofs without the need of a primer.

We use RMA's XTRM roof sealant almost exclusively in our service center.
It adheres to any roof type: EPDM, DiFlex, Alpha Systems, Fiberglass, Filon and PVC.
Plus because it is not a "solvent" based caulk, it does not dry out and crack over time.
Most caulks in the RV Industry are solvent based. This is why your roof caulks tend to crack, chip and peel.
I highly recommend RMA's XTRM roof sealant.
