My roof is past its best-before date. It's 18-19 years old & asphalt shingles.
The worst areas are above the sunporch, and the back part of the house; the pitch is only 2/12. Furthermore, the soffits weren't vented until last year, so that didn't help.
We have had a couple leaks, and I've been up to patch & seal them, but the roof is just beat... plain and simple.
I was originally going to just pay someone to do this, but I have several friends who have done roofs. A couple of them were over this weekend and they pretty much convinced me to get a 6-8 man workcrew together and DIY. The $$ saved could be put into much higher quality materials, and I'd still have enough left over to build a new deck this summer.
Now, I have never done a roof before, but I am pretty handy. The two frends who were advising me have each done 4-5 roofs. One of them has led 3 similar DIY projects on family & friends' homes, and he has offered to help me out. There is no way I'd tackle this without his help; he is not just a DIY'er but has worked full time as a contractor and has built homes. He is also very fussy & thorough, and works very very carefully. I have helped him out a few times and he really wants to help me tackle this.
Question:
Originally, I was going to put down asphalt shingles. However, my friend told me that with the low pitches, many more people are using peel & stick roofing. He said that a few years ago it was an "unknown", but it's pretty much proven now. Some of the peel & stick products are guaranteed for 20 years, which is more than you can get for any shingle installed on a low pitch.
I'm thinking about using it on the areas marked with yellow:
Anyone have any exprience using the peel & stick stuff?
More generally, anyone ever done their own roof before? What should I expect? What kind of precautions should I take? Any tips?
