Roof Sealant and Wall Repair

Hello All, I would like opinions regarding good product to seal seams and cracks on my fiberglass roof. Also interested in hearing others experiences with rotted plywood in the walls, I have a couple of bad spots! Seems the frame is welded steel, should I remove the bad plywood from the inside and then repair the interior walls? Is it possible to remove an entire exterior wall panel?

When we purchased our new-to-us MH, one of the first things I did was apply Eternabond tape and Dicor caulk to all seams on the roof. A little water can do alot of damage.

Can't answer about the wall panel, maybe someone else will respond.

Odds are the sidewalls are vacuum-bonded sheets, with the exterior a sandwich of filon and luan plywood and the inside a sheet of wall-papered (or vinyl) plywood. All glued together and glued to the metal structure as well. You can't get at the outer plywood from the inside and vice versa. So, the first question is which side is damaged (or both)?

For vertical seams (what cracks?) use any good grade of exterior caulk, e.g. Geocel Proflex RV or a window & door caulk. For the roof seams and around roof openings, use Dicor or Alpha self-leveling sealant. If you prefer, you can apply Eternabond of Dicor tape. You would need to remove old caulk first to get a clean flat surface for the tape. Also, the tape can be difficult to apply tightly to curves and around openings. Sometimes the self-leveling sealant is a lot easier.

Thanks Gary,

I fear both sides. There is a trim piece that runs just below the roof line front to back, looks like a silicone sealant on it. I am wondering if it covers a seam and if I should try to clean the silicone off and re seal. I think I am dealing with a get what you can out of it situation, slow the death sentence kind of a deal. I hope to get another 8 to 10 years out of it! Any thoughts or ideas welcome!
