It's funny how I now realize when you fix 1 thing you find 3-4 more things needing fixing. While on the roof I noticed these lumps and this one huge lump. Recently I have sealed up the holes in the floor (underbelly problems) and other places so tight that I think it's a moisture problem from inside that's doing this to the roof (which was probably already bad). So I lifted up a couple of shingles to find the wood (under the biggest lump) has warped out leaving the insulation exposed. There is also a small crack in the ceiling on the inside where hole is in roof. Looking down the roof I noticed the same kind of lumps but not as extreme as this one. So I had planned on getting bathroom vents anyways (but was planning on doing the wall vents so I wouldn't cut holes in roof) and now that I figure I'm gonna have to replace the wood on the roof I might as well install them then. So any tips and advice on this would be greatly appreciated. I am a girl who's never done this before either, but am up for the challenge (I hope). I'm also thinking of removing the old swamp cooler thing on the roof and the tube that runs the length of the house leaving those horrible looking dust collector vents in the ceiling - yuck.
Oh yea, I'm In phoenix and live in 16x66 single wide 1988. And I believe it's called a gable roof?? and upside down V...
