Which Sealant to Use

I purchased a vent cover for the roof of our motorhome and I'm looking for recommendations on which sealant/adhesive to use when I mount it. It's one of the Camco vent covers that has louvers to keep rain out and is sloped on the one end so vent can be open when under way. I figure I'll mount it with sealant first then put a few stainless steel self taping screws just long enough to penetrate the roof about 1/4". Or are the screws even necessary with the right kind of sealant/adhesive ?

I'm not sure if the roof is rubberized or just coated. The material on the roof isn't exactly soft like rubber, but it's some sort of coating over top of the fiberglass.

There's a lot of different products at the home centers that I know would work, but might not be the best choices.

Thanks in advance for any recommendations.

Most vent covers come with mounting hardware and don't require any sealant or holes in the roof.

3m 5200 is messy and hard to remove if you need to but it will seal anything!

There is nothing to seal. It doesn't mount to the roof, but to the vent itself.

if you seal it to the roof you will have two issues:

1. any water that does happen to get in through the louvers will be trapped there.

2. WHEN you have to remove it for cleaning or maintenance you will be in a world of hurt.

mount it to the vent frame with the hardware provided. no sealant!
