roof leak

roof leak

I have a '96' Innsbruck TT 26' and recently whenever we havce a rain especially with wind I get water dripping through the A C grill in the cieling. Looked up top and the EPDM seems to be in pretty good shape! Should I try caulking around the base of the AC ? Any ideas or suggestions?

I'm no expert, but from what I've read; clean the existing caulk and then apply a good leveling caulk, such as dicor. Some would suggest a good cleaning and eternabond tape and then the caulking. Do some searches here our on YouTube and you should be able to get the idea.
Hope that helps a bit.

DO NOT caulk the A/C unit. First thing to do is to tighten the four bolts inside and see if it is just a little loose. If this does not stop the leak, you will have to remove the A/C unit and replace the gasket.

The gaskets are available from any RV dealer and takes about 30 minutes to replace. The prime thing is to not over tighten the gasket.

But DO NOT caulk the A/C unit gasket.

Other leaks you can use the Dicor sealant or Eternabond tape.
