Our experience in working with home owners is that many believe the process of installing a new roof is no more than nailing new shingles to the existing surface, and that anyone with a strong back and the willingness to challenge the hazards of walking on top of a house is qualified to do the job. The reality is that steep slope residential style roofing is a highly technical procedure. Installing a new roof without proper education and skill could result in deterioration to the structure of the home, as well as troublesome interior leakage.
