roof leak

[rode2nowhere]

2011 keystone sprinter 311bhs, found a soft 8x8 inch spot at passenger side rear corner, yes a crack in the roof sealant, how would this be repaired? There is no water in the trailer. Any ideas appreciated...

Holy cow! Roof leaks are a pain. The biggest thing I would tell you is that it's critically important to make sure it's dry under there before you seal it up or, you're in for a long term series of downward spiraling aggravations. Just me here.. I'd cut out everything that has become unbonded and let it thoroughly dry out in there. Get a big tarp at Harbor Freight if you have to and cover the camper. It's easier to do it when it's hot and dry outside. When exposed to the hot sun it dries really good and thorough. Let it dry a couple of days. Then evaluate the wood. Make a decision on replacement, partial replacement, etc.. Then cover it with a piece of EPDM or something like Eternabond tape. It needs to be sealed up completely dry. Water trapped under the Etarnabond will make the not-so-eterna-bond fail. If your roof is EPDM, and it probably is, only use compliant products. No silicone and no roofing materials from the local hardware store. Liquid EPDM rubber is a possibility. I have used it with some success. It's peculiar to the surface you're applying it too and, like I said before, if there's any moisture getting trapped you'll be wasting your time with it. The most critical issue is drying out that moisture completely. If you're working with a bone dry surface everything goes pretty easy.

If you can build a dog house, you can repair a soft spot of that size on your trailer. It will take an afternoon of your time.

If you're really hesitant about doing the carpentry, visit the big box store and buy some Git-Rot or similar epoxy for rotting wood. Apply it to the soft wood, let dry, and roll the roof membrane back into position, using some adhesive. When you have the membrane back on, cover the seam with Eternabond Tape.

If you need a break in this process, tape a garbage bag onto the membrane across the work area. That will secure your rig from rain until you can complete the repair.

good luck is right, I have no garage, and it looks like a time consuming job

Cut out the roofing where it is soft, replace all rotted wood there. I used Liquid EPDM to repair my old Nash roof. The liquid EPDM gets "painted" on, for lack of better word, and forms a seamless repair, adhering to the existing EPDM roof (if that's what you have). Make sure to repair everything right the FIRST time, or else you will eventually be back in their a SECOND time.

Any wood that is soft or wet needs to be inspected and probably replaced. I would either cut out the rotted wood, or else use one of the epoxies meant to harden rotten wood. Then I would glue additional 2x2's to sister anything that is rotted. Replace the rotted roof decking, making sure to get all the rot out and replace it with good wood.

Its a pain in the neck, but it is something that can be a DIY project. When in doubt, replace it. Don't go in a second time. Good luck!
