Bubble on my rubber roof

[Conquest123]

I own a 2000 Conquest by Gulf Stream looks like the person that owned this motor home before me hit a low branch and knocked out the antenna. In doing so pulled up the mount. I took it in to an RV repair shop and they repaired the mount and said it had been leaking water. Now I have an air bubble under the rubber roof about 1 1/2 foot by 2ft.Concerned about farther damage. I’m thinking cutting a hole in the roof to relieve the air bubble and dry it out then put adhesive under the rubber to secure? Put a patch over the hole I’m sure someone has experienced this problem before I would really like to know how you dealt with this problem our a rescores to find out. Thanks Conquest123

Thats about the way to do it.. I would only cut big enough to let the air out and to shoot glue in. About the size of a pencil (1/4") should do it.

Thanks for confirming that do you know what woyld be the best glue something that doesn't excel a gas that would compound the problem? Thanks Conquest123

Butyl rubber is prolly what is mostly used.. couple of syringes and a seam roller (or kitchen rolling pin ) and you should be ready to go.

Original rubber roof would have been installed with contact cement. Your on the right path just make sure the glue is compatible with EDPM rubber. Than put Eternabond tape over the cut.

West Marine sells super sized syringes for injecting adhesive/resin - might come in handy for this type of fix. Worth a Google.

Anytime your going to cut your roof membrane you should consider using eternabond for a patch - once the patch is in place you can be comfortable that it's not going to create future problems.
