Roof Soft Spot

While cleaning my roof I noticed a soft spot over the bathroom area. There is a very small pin hole, see the pictures next to the penny. In Florida we have been getting a lot of heavy rain. I tried to look inside the attic, removed the inside skylight and the collar around the vent fan - no luck. I rigged a fan to blow up into the attic around the vent fan to try to dry the wood out but I don't expect much luck with this since the roof plywood is encapsulated with foil insulation inside the attic and rubber roofing on top.

My thoughts are to cut 3 sides of the rubber roofing around the area, peel it back and dry it out to see if I can get away without replacing the wood. My concerns are how to reattach the roofing if successful and how to proceed if the wood is too far gone. Any thoughts would be appreciated...

If successful you could reattach the flap and cover the cut with eternabond. If not you could try peeling back the roof depending on where the hole is at and repairing then reapply it or pull the whole rubber off and put new on.

After you pull your flap back, first concern I would have is how much of the plywood is actually damaged. If small, after you dry it out, apply one of multiple products at Home Depot for restoring rotted wood. I used on a rotting window sill in one of my houses, and after sanding and painting, you could not tell there was a patch. Eternabond tape would work fine for reinstalling the flap. IF the moisture has spread throughout a significant area, you have a major repair on your hands.

Great idea on the product for restoring rotted wood. You can see in the pics the size of the area. In your opinion would the products repair an area that size? Thanks.

That's a pretty small hole. If its soft in your taped off area, I would cut it on three sides around 3 inches beyond your tape, leaving the side to the front un cut. Blow a fan on it for several days to dry it out. Check the woods condition after that. If you cant easily poke your finger through it, call it good and lay the EPDM back down and Eturnabond tape it

If it seams that the wood has been damaged, Place a piece of 1/16" aluminum over the damaged area and tape it up.

Hole size is not as important as how long it has been leaking. Longer the time, greater the potential for damage. Wood restoral products are designed for usage with small damaged areas. If you are lucky, easy repair, based on your photos.

Peeled back the EPDM and I will be able to dry it out, if necessary use some of the wood rot products to firm up the wood. Have a fan on it now but rain expected again today, it will take a while to get it dry. Regardless I am very fortunate to have caught it early. I will make it a habit to get up there to inspect more often and suggest everyone do the same. This small pin hole could easily be overlooked.

Does not look to bad. Obviously if its going to rain you need to keep the water out. Tarp the camper ?. Get the area dried out and tape it up with eturabond. It will be good as new.

Great suggestion on inspecting the roof. I go up on mine often and crawl around on my hand and knees looking for any signs of damage. It does not take much to create real issues.

That looks like a hole I found on my roof after a hail storm. The only reason that I found it at all was there was some damage to the side aluminum structures at the edge of the roof and it turned into an insurance claim. The adjustor said that if there is any damage to the roof they total the whole thing. They do not repair it. At that point I looked into what to replace it with. Chose RV Roof over EPDM. Better product, lifetime warranty, no worries about hail and most limbs. I will never have an EPDM roof again. And more than $1,000 less expensive than EPDM.

Butchy your roof material is TPO not EPDM. Make sure what you use is compatible with TPO.

What do you think made the hole? Doesn't look like limb scrape. Maybe rock on bottom of shoe. Maybe flaw in manufacturing?

OSB doesn't handle leak well. Plywood wood have done better.

Thanks for the info. I believe a tree branch fell on it and stabbed that small hole. It was not there in March before we left on a 3 month trip in April. I had cleaned the roof then. I bought some epoxy that is supposed to be thin enough to penetrate and harden the soft spot. I will post pics when I complete the repair.

Need a recommendation for adhesive...

I’m finally getting the repair completed. Today using the wood rot epoxy, picture below. Next step - what is recommended for adhesive to paste the roofing material back down? I see some products advertised (Alpha, Dicor) but cannot find anything less than a gallon. Has anyone used something else successfully, contact cement, etc.?
