Washington's housing stock, especially in the Seattle metro area, features many homes with pitched roofs, where asphalt shingles are a prevalent choice. Our asphalt shingle roof replacement process begins with the careful removal of your existing roofing materials down to the roof deck. We meticulously inspect the deck for any signs of rot or moisture damage, replacing compromised sections to ensure a sound foundation. A high-quality underlayment is installed across the entire roof surface, followed by the application of a robust ice and water shield along the eaves and in all valleys. This is crucial for preventing water penetration in Washington's consistently damp environment.
