We have a 1992 Winnebago motorhome and I noticed recently that we were getting water come in at certain places so I checked the roof and the canvass over the wooden roof has deteriorated so much that there are big tears in it and the wood is rotting underneath. I have been quoted between $10 - $15 thousand to get the roof replaced and a fibreglass roof put on. Has anybody else had experience with this and any suggestions. I can't afford that sort of money and if I had it done I would have to sell up to recoup the money as we are pensioners.  I think most modern motorhomes have a fiberglass body already but these older ones have that tight canvass stretched over a wooden roof. It probably has lasted until now unless a previous owner has had it redone. I probably should have been doing regular checks of the roof and sealing where necessary.
