Hello!
We just bought a 88 31 ft class A. It's in decent shape and have begun doing some updates inside. The roof needs some love.. I thought it was a rubber roof but when I pulled if some of the coating that was peeling up it was metal underneath. I want to put a liquid rubber coating on it but I am confused as what product to use. I dont know that the roof was coated with previously. Looks like a couple different types. I have looked at dozens of different products online but have no idea what to use. I dont think I can scrape off all the old coating to get back to bare metal, so looking for a product that will adhere to metal and old coating.

Check out an elastomeric roof coatings. Henry's has one but I think there are better quality products available.

If you use the search engine here you can find old threads about re-coating your roof. Prep is paramount. I think the Henry's would work though. It is supposed to deaden sound, insulate against the heat (reduce heat inside by 20*). But again, the prep needs to be done.

A picture of your roof might help people to better advise you.

Just did the metal roof on my 89 Tiffin Allegro. Did a wash down with bleach,let dry then two coats of Kool Seal Elastometric roof coat.

A few months ago I redid my metal roof. It was in poor shape with multiple pinholes everywhere and several failed coats of elastomeric coatings.

I ended up using a two-part product called Liquid Roof; it is actually liquid EPDM rubber. You can use their primer product to go over existing coatings, but with the level of failure in the old coating, I opted for removing the old stuff.

I scraped the loose stuff, used some paint remover in some spots, but the bulk of the removal was done with a 7" angle grinder and a wire cup wheel. It was messy and quite the job, but I got great results. The multiple roof leaks that ruined the inside of the coach before I bought it are a thing of the past as it is now protected by a thick layer of EPDM rubber.

Thanks for the info, the wire cup wheel on the angle grinder worked wonders for getting the flaking crap off. I wasnt able to get the EPDM 2 part coating here in Canada, ( small fortune to get it shipped up here and across the border). I found a liquid RV roof supplier here. Stuff had good reviews so I gave it a shot. Turned out pretty well i think. Was nice and thick and feels just like rubber.

Glad to hear that was helpful information. I definitely don't know what I would have done without the wire wheel for that job.

What is the name of the coating you used?

Love to see some photos!

I used RV roof coating from Liquidrubber .ca

After grinding off the coating at the back there was a bunch of holes with tons of silicone globbed all over, so I attached new aluminum over the areas as well as covering the 1 nasty skylight repair that was done (over the shower)Glued,screwed and sealed with tape then roof coating.

I used this product on a leaking metal roof on a shed and then later on metal TT roof.

After 4 year I put on another coat. I used a pressure washer to clean dirt off and the coating was still in good condition.
