Roof repair

[Outlaw]

I have a 2006 Jayflight 26’ JTX and I noticed that on a section of the roof near the front of the trailer the plywood has pulled away from the frame. It has not punctured the roof membrane but it has caused it to separate a bit and a small void is present. Does anyone have some repair gudance on this? I’m afraid to pull back the rubber roof as there is not a leak at this point but I’m afraid it may create a long term issue if I don’t do something. Someone suggested cutting out a section and make the repair then patch the section. The roof is showing it’s age but still has life in it. Any ideas?

Does the plywood seem hard, firm, and strong when you press it? Or does it feel weak, spongy, and deteriorated?

I have an idea, if the plywood pulling loose is not caused by water damage. If it has just come loose because it was not fastened down correctly in the first place, my solution would be to locate the roof rafters (wood??) and drive a screw or screws through the roof membrane and plywood decking into the rafter(s). I'd try to work the screw heads under the roof membrane and sink the screw heads into the rafters, and cover the hole(s) with a piece of Eternabond.

If the plywood is loose due to moisture and the decking just falling apart, I'm not sure the above would work as the rafters could be damaged/spongy/rotten.

You could just cut open a flap of roof material (even leaving one or two edges of the flap intact), see what's going on and maybe be able to fix the wood. The cuts in the cuts in the roofing membrane could be easily fixed with with Eternabond strips. You could even take a look and decide to leave it alone if the damage is too great and then re-seal with the Eternabond.

Overall, it does not sound like good news for your roof; water damage can be very extensive. But anything can be fixed!

Thanks for responding. The plywood seems rigid and structurally intact, no moisture damage that I can tell. I think I am going to try your suggestion. Someone I spoke to suggested the same thing but using stainless screws with fender washers then covering them with dicor. Either way seems to be a viable solution

I agree with RVhiker: I would cover the screws and any membrane cuts or perforations with Eternabond and Eternabond sealany caulk. It is designed for all roof types, and it will hold up better than Dicor - just a better product.
