TPO sealant and repair

[Bullet Boy]

I have a 2015 Bullet 248rks,, I’d like to know the appropriate material needed to seal/refinish existing roof material. I have no known leaks and used some self leveling last material before unit was stored last fall and the only areas that seemed questionable at the time were where the cap meets the roof on the front and same at rear, seals around vents and such seemed ok. 2nd question, just came back from 11 day trip in Cape Cod, parked rig, set up electric and shut down fridge. Typically we leave it running but this time we shut it off and cracked the doors. I noticed water dripping dead center of rear of rig at edge of chloroplast. Found water pooled in freezer and I’m assuming some dropped out of fridge down the drip catch. Where does the water go??? Is that what was dripping, isn’t there supposed to be a drain tube somewhere? Ok, 3rd question, will my roof support my fat arse to get up and do some general maintenance, I’m a healthy baby boy 280lbs......thanks for the help

In photos of these rigs, I see no ladder installed for roof access, so I would not attempt to walk on the roof, because the lack of a ladder is a pretty good indicator that the roof is not strong enough to walk on without additional work. Routine maintenance for rubber roofs, EPDM or TPO is similar, usually just use Dicor self-leveling sealant to repair any cracking in the sealant of the roof. Hopefully the water in the belly of the rig was just from rain blown in when driving, otherwise you may have a leak from plumbing or a tank.

The leak actually was caused by the drain tube from refrigerator not being routed outside. On a good note, I fixed it by routing it out through the louvered cover panel. Don’t see any apparent damage so I leave it alone at this point. So if my roof can’t hold weight, how does one do maintenance and caulk seams. Doesn’t make sense to have to built a scaffold to do said repairs. I’ll dig further. Thanks for the input.

Checked Keystones owners site, no ladder, no walky!!!
Now what....My arms are short and my belly’s big!!!

A tall ladder laid against the trailer sidewall and a 1" sheet of rigid foam insulation board laid on the roof (to support your "rotund belly") as you lean across the foam board to access the roof seals with your "short arms"???

Instead of dicor, use 4" or 6" eternabond tape and never worry about it again.

Until you need to get under the tape to re secure a screw backing out or you need to do some minor work and have to try to peel off the tape.

IMO, eternabond is good for a repair as it is permanent (hence the name) but a poor choice for routine maintance.

Totally agree!
It's a great fix for a nick or hole in the roof material but the wrong fix for joints & around roof protrusions, it's PERMANENT hence the name.
Your roof shouldn't require more than regular inspection, cleaning & reapplying/refreshing the caulks on joints & seams. No sealant required over the entire roof.

YES, it's permanent as in no more maintenance of the joints. As far as a screw backing out that is easily dealt with by cutting the tape, fixing the screw and applying a patch of more tape. At 77 I don't enjoy getting on the roof any more and paying the RV shop $300 twice a year is a pain in both money and time. Better to leak proof the joints before the water gets in, now I don't have to worry about the roof again EVER! YMMV.
