Roof sealing

Possum3 · Guru

You say that you've been trying to trace a couple of leaks for years, so I imagine that you have an old passenger bus that has several panels rivetted or bonded to a frame (of either wood or metal), underneath the roof skin and there is a ceiling attached to underside of framing.

The correct method of leak repair is to remove sections of the ceiling and determine how much damage water has done to the frame (especially if it is timber).

Coating the outside of roof with a film of polymer would only hide existing damage and risk the integrity of the roof structure.

I have a bus converted as a motor home. I've spent a few years trying to trace a couple of roof leaks. The suggestion is that I paint the roof with a plastic sealing paint. Anyone got any experience in using this type of product

I have had wonderful results with Eterna Tape - also from Bunnings as Gorilla.

It is quite flexible so ok to tape over joins that may have some flex.

Needs thoughtful skills to install neatly.

3 years now on a flexible Jayco water bucket and absolutely no problems.

Good morning ladies and gents.

Its been a little while since Ive been on here, just had a lot on.

I recently found this at Bunnings to seal some joints (not on the caravan). First time Ive seen it, and I am quite impressed.

It is called One on One double sided sealing tape.

I would use waterproofing tape (sticks like **** to a blanket) and the waterproofing paint , used by tradies in shower recess prior to tilling,sold together in kit form from Bunnings. Follow instructions carefully and prep is key to good bonding.Then paint with epoxy paint or simillar.

Thank you folks for your suggestions. I cannot trace the origin of a couple of my leaks as built in furniture/cupboards have restricted or allow no access to the inside of the roof which leaks. I have found rust spots and fixed them by digging them out and patching. All my troubles started when I had the vehicle fully resprayed some years ago. The earnest preparation highlighted but covered up problem areas. A number of these areas have been fixed. My main issue is that I'm 80 next birthday and as the life of my RV will be limited to me (never to be sold) so an extensive roof repair is just not realistic. I've found a couple of patching options at bunnings which I have used with some success. All the seams are taped, however what its like under the tapes is anybody's guess.
