Every brand of asphalt shingles makes a comparable product. They are manufactured with the same technologies and even purchase their granules from the same company (3M). The true protection of your home and the controllable variable in a successful renovation is the company that provides the service. The most common leak points in a roof are where flashings and technical installation details are performed. The roofing industry and contractors in general have poor reputations because of the lack of information relating to this. Whether 180 contractors or does your roof replacement, it is vital to have confidence in the people and guarantees behind your roof. Roof replacement is a purchase that protects your home, and is supposed to last multiple decades. Ensure your contractor is well known. Get an understanding of how they handle problems, ask for references, and be confident with who you choose. Otherwise, you can easily end up in many situations before the shingles laying on top of the house for decades begins to deteriorate.
