When it comes to experience, we beat the competition with an average of 30-40 roof installations a month and have been installing roofs for years. We are also GAF Master Elite contractor, a qualification that is currently only held by a few other roofing contractors in the state of Washington, and in the USA less than 3% of all roofing companies qualify for this level of certification.
What this means to you is the labor and material is covered by the manufacturer instead of the roofing contractor for the life of your roof. Additionally, we are IKO Shield Plus Pro Contractors, a certification reserved for a very exclusive group of contractors in the state of Washington. These certification in addition to our high level of quality customer service and expert installation team guarantee TriState as the superior choice for roofing contractors in Mercer Island, WA.
