Leaking roof

I'll second what mobilefleet said. Eternabond is excellent stuff. I used it on a roof seam leak on our old HTT. That was 3 years before we traded it. It never leaked again.

If you can, open the area up a little and let it dry out inside before you reseal it. In my case I was able to remove the molding across the seam and "peel up" the curved aluminum panel on the front to let it air dry for a couple of days.

do not use silicone or latex caulk of any kind on a rubber roof. Best thing to use is dicor self leveling sealant found at any rv store, and followed by eternabond seam tape across the front and rear seams. Dicor also makes a "non-sag" sealant that can be used on all other places other than roof, and you should use it around your clearance lights. i highly recommend you remove the screws of each light and dip them in sealant and reinstall them, or replace them if rusted. One of the most common unthought of causes of water damage due to water wicking in through an unsealed screw. Some folks recommend Proflex sealant, but I don't like it because it's too hard to work with and comes out of the tube too tacky to make a nice looking smooth seal using your finger.

Thanks I guess now I need to work on removing the silicone caulk.
