THREE LAYER CHALLENGE! This 25 square roof on a home in Bryan was quite the challenge. We removed two layers of asphalt shingles, plus an old layer of cedar shake shingles (not fun). In doing so, it was necessary to install 7/16″ OSB sheeting over the entire roof to make a proper subsurface for the new Duration shingles.
I only install Owens Corning Duration shingles simply because they are the best in the business. They include a lifetime warranty, a 130 MPH wind rating, and a super tar seal! Click below for more details:
