Permanent fix for roof cracks

[flyboytravel]

I have some small cracks forming around the ladder mounting bracket and along a seam on the roof of my class A. The previous owner used a rubber sealer but that seems to be temporary fix at best. Any suggestions for a permanent fix for this problem?

What is it that is cracked? If it's an EPDM rubber roof, the rubber just needs sealing. But if the crack is in the wood structure underneath, you may have to get under the rubber and do some carpentry.

If a fiberglass roof, it will need some reinforcing, maybe by building up the roof in that area with glass cloth and resin.

Cracks in the existing sealant just need more sealant.

I really like

Eternabond

. I would most likely make a patch around the ladder (as tight as possible) and then add a touch of Dicor lap sealant where the Eternabond meets the ladder.

Both these manufacturers make high quality products in my view.
