How To Repair Rotted Plywood Under Rubber Roof Of Camping Trailer

Topic: Repairing soft spot in RV roof

---

Posted By: Frankandbeans on 09/03/15 07:52pm OK, first off I repent as I know this is non a new topic. However, the standard "search, information technology's been covered x amount of times" is rather quite useless when the links are 5+ years one-time and none of the pictures work. I have roughly a 1.five' square pes soft spot in the corner of my toy hauler. I can tell it leaked correct at one of the seams, as at that place is undoubtedly a clear, directly line where the roof is solid and then gets soft. I did find a small tear in the EDPM roof (branch or something must take tore it since I checked it in the beginning of the yr).

So my question is:

How exactly exercise I brand the cut into the roof to access the rotten wood to supervene upon it? Should I cut a "H" pattern? I can probably figure out how to replace the wood once I get to that point, only my question is how/what do I employ to glue/repair the EDPM roof? Is it acceptable to use Eternabond and just "seal" the roof back together? I am still trying to effigy out what the "good" products are out there and what route I should become with.

Posted By: westend on 09/03/15 08:05pm Usually. you can lift the EPDM membrane off the rotten roof capsule if the damage is towards the edge of the membrane. Some rotten woods may stick to the underside but is easy to remove. After completing the wood repair, glue the membrane back downward with EPDM agglutinative.

Tears or cuts can be repaired with Eternabond tape.

Posted Past: Frankandbeans on 09/04/15 08:33pm Thanks for the reply. And then it is on the edge of the membrane (Where the rain aqueduct on the side is). How far off would my plan be in this case?

- Remove that pelting channel to remove the screws/staples on the side holding the EDPM down.

- Cutting two slits in the rubber roof so that I tin can peel up, starting from the edge manifestly, the roof allowing me to admission the rotted wood.

- Repair wood and employ whatever EDPM glue to adhere roof to the new repaired forest.

Now the large question - what about the seams from the cuts? Patently information technology should be more often than not sealed from the glue that I would imagine would overflow out of the cuts, just simply to verify, I can just use the Eternabond tape to seal that seam, right?

That is exactly what I would exercise. The Eternabond tape will seal up the cuts. If y'all want to brand absolutely sure, simply put a dewdrop of Dicor self leveling caulk on the edge of the tape after you put information technology down and rub it in.

That step is probably non necessary however. I used Eternabond record on all the seams of my trailer 8 or nine years ago and it yet looks like new and does not leak. I did not put caulk on the edges. Your plan looks good to me.

Posted By: westend on 09/05/15 12:00pm I think you take it but it may not exist necessary to cut any slits in the membrane. A lot depends on where the repair needs to be done. The metal trim edge on the roof and the agglutinative is what holds the membrane in identify.

when you lot reattach the trim edge apply stainless fasteners and/or seal the fasteners in the holes. Fastening through Eternabond tapes seals the fasteners, too.

- Remove that rain aqueduct to remove the screws/staples on the side belongings the EDPM down.

- Cut ii slits in the rubber roof and then that I can pare up, starting from the border obviously, the roof allowing me to access the rotted wood.

- Repair wood and employ whatsoever EDPM mucilage to adhere roof to the new repaired wood.

Now the big question - what about the seams from the cuts? Obviously it should be mostly sealed from the glue that I would imagine would overflow out of the cuts, but just to verify, I can only apply the Eternabond tape to seal that seam, correct?

I have the exact same problem , soft area , similar size and scope , and was wondering how yous fabricated out. I'll probably do the same process with mine, thanks, Bob

Posted By: RVcircus on 10/27/15 04:16pm Be sure to audit for boosted rot/water damage beneath the plywood. When I went to ready my roof corners it turned into an unabridged roof, the rear half of the trailers walls, and 6' of flooring joists. It's amazing what secrets siding tin hide if you don't wait closely.

Getting too cold to work on it...put a tarp roofing the entire roof and then it's covered for the winter and will mess with it in the spring.

I believe I did notice the cause of the leak, a very small (ane/2" or so) tear in the EDPM, probably from a tree branch or something. I used some Eternabond and that Flex-seal stuff ("as seen on Idiot box") to patch in the mean fourth dimension.

Maybe if I'one thousand really lucky, a Shark-nado will hitting the area and I tin file a full loss merits with my insurance visitor, claiming the trailer got destroyed by flight sharks. And then I'll go back to an enclosed trailer and not have to deal with this stuff anymore.
