Ok I have a double wide mobile home with a really bad roof. The shingles are shot, the osb underneath is rotting from the exposure of water, and the insulation is starting to mold. I posted about one of the leaks here. Unfortunately this is only one of the many leaks. It rained the entire weekend and several of the leaks expanded and the ceiling started to fall out in more than one area of the house. I need this roof to stay alive another three months till i get the money for a new roof!! Is there anything i can do besides replace the whole roof?
I think many of the leaks, which are at the very edges of the house, are coming from the crest of the roof. The reason i think this is because i put rolled roofing over the top of one the leaky spots in the roof and it didn't change the leak AT ALL. Even if it was a poor repair on my part it should have at least slowed the leak a little. Also the ceiling sags for several feet before the actual leak in the ceiling (I put the rolled roofing over the sag as well). So i think the water is getting in at the crest and running down to a point where the osb is rotten. This make sense to me because the rolled roofing was placed over the shingles and not the deck itself. So the water would still run under the shingles and the rolled roofing both if it came from a point higher up on the roof.
Does my theory make any sense first of all? If that makes any sense how can i stop the leak coming from the crest? Also, If i'm off base on this one what do you guys think could be going on?
