Whether you are Replacing your existing roof or Reroofing (also Re-roofing) knowing which method of roof replacement or repair is best for you can be determined by the expertise of Sawtooth Roofing staff. When we reroof, Sawtooth experts go through the process of layering one set of new shingles over a set of existing set of shingles. Reroofing is only done once, so if you already have two layers of roofing in place already then, reroofing can not be an option for your roof. Why reroof over replace? There is no demolition (or tear off) of the old roof, as a result, reroofing can cost less and reroofing typically goes much faster than a complete roof replacement. Therefore, it’s vital to rely on a trusted Sawthooth roofing professional to supply good advice about the roofing products and procedure options for your home.
