All right guys, it seems that I keep running across problem after problem. Now its my roof. I have noticed in the past few weeks that my shingles are looking really bad ie; peeling and breaking. I can see some sagging spots on my roof which worries me also. I went up today to clean gutters and noticed a few spots that looked sunken in and a few spots that felt soft when I walked on them. So I am guessing it is time to learn how to roof. I would love to just pay someone to do it, but I am tapped right now because our basement is in the process of being dug out and straightened. So I got the general idea, rip off old shingles ( yes I have 2 layers already ), replace any bad sheathing, lay down tar paper, and nail the shingles on the roof. I understand that it is a bit harder then I made it sound, such as where to start shingles, ridges, and whatnot. But it seems pretty simple, which worries me. Am I getting in over my head or is this a pretty straight forward job to undertake as long as I don't mind doing the hardwork? One thing I cannot figure out as well is when I start tearing off ,what do I do if it rains? I don't have a tarp big enough to cover the whole roof? What is the process to this? Any tips or help is appreciated. Thanks guys.
