Sealing a roof

[Shoulder]

I need to seal the roof on my RV. It is an 89 Pace Arrow Fleetwood. It looks like the roof is made out of shingles but it is not. Same type of surface finish, but it almost looks like there are fiberglass strands in it.
The factory sealer is white and still soft in most areas. Someone has sealed the roof over that in many places with a black sealer I don’t know what it is. What should I use to seal this? I saw some roofing sealers at Lowes and Home Depot are these ok to use.


Thank-you

You need to find out exactly what the roof is made out of. If it is that EPDM and you use the wrong stuff you will have to pu a $6000-7000 roof on it. If it is EPDM rubber and it is just old then go up this site

You cannot use a petroleum based product on rubber roofs.

If it is EPDM rubber you can use the EPDM based rubber roof coats available in most home and hardware stores. Kool Seal is one common brand.

I can't imagine what sort of roof looks like shingles. Is it some sort of overlapping layers, which is what I think of with a shingle roof? The "looks like fiberglass strands" suggests an EPDM rubber roof where the rubber has eroded away and left the woven fabric base exposed.
