Hi, I purchased my house 4 years ago. It was built in 1993 and the shingles show wear. Should I get a new roof? I am also considering doing it myself. While I have limited roofing experience I am very mechanically inclined and feel I could do this job. I just find it very hard to pay $6000+ for something I could do for $2000. I am thinking tear off as that seems to be the preferred method.
