Help! Trailer roof repair/replace advice...

Thats not EPDM; that’s a coating.

This is EPDM, with the video not being completely accurate, depending on installer. For instance, Mule-Hide adhesive is not water-based; it’s just like contact cement in a tube, which is to say, when it’s stuck, it’s stuck.

 

2 guy's willing to take a ban over trailer roofing...

 

If the educational aspect outweighs the non-mc content, I think you can get away with it.

Besides, it is in regard to restoring a trailer that hauls bikes for a racer.

 

I think we need more pictures

 

Good video @YamahaRick . TBH, I never thought to look at the rooftop of a trailer when I was seriously considering a purchase of one. I'm sure the sun gives the rooftops a beating. The video doesn't show if the gap under the rooftop hvac unit was also treated. I'd assume so?

 

Thank you! I don’t know what the fack is wrong with these boomers today!

 

Ok! Done with sealing and sanding. Do I use POR15 Rust Preventative paint to coat the metal on top of the trailer or POR15 Top Coat? Or both?

 

Paint, then topcoat . The rust preventive paint cant handle the UV's

 

Get some of their solvent too. It's the only thing taking that stuff off your skin other than a grinder.

 

I would use the rust preventative paint as a first coat, to help ensure the rust doesnt come back underneath the paint. Then a good UV stable top coat.

 

I've sprayed all the rusted areas (after I wire wheeled and sanded) with a rust resolver/primer product. What's your opinion on spraying the whole roof with a few coatings of Flex Seal and calling it complete? I have found that Flex Seal is UV resistant (or so the interwebs say...)

 

And if the trailer flips over during a flood you have a boat.

 

Im betting its not. Roofers use a product by GACO that is

A roof supply would have the 1 gallon cans... ~$50

You could just coat/paint the bad areas for now. But as old as the roof is I would eventually paint the whole thing.

I wouldn’t use flex seal.

 

You'd be better off getting a 5gal bucket of Kool seal from home Depot and rolling on a few layers

Probably cheaper than flex seal too

 

I tried the flex seal spray can for some of the random areas on the trailer sides. It was garbage and didnt hold up or cover well. I sanded it all back off.

Someone mentioned KoolSeal, and I've heard great stuff about it. I used an aluminized trailer roof paint, waterproof, heat reflective, 1 year warranty. I'm happy with it.

Edit: 1yr warranty. The 10 yr is the seam sealer/caulk, that's under the permanent/waterproof 6" wide tape, that's under the aluminum roof coating.

 

What he said ^^^

Once a year, I go over the seams with lap sealer and then paint the roof with that kool seal, or a version of it. You can get some from Home depot/Lowes. It's not in the paint section, it's over in the lunberyard part of the store. I also replaced the foam a/c seal every 2/3 years to keep it from leaking there.
