Choose your city
Washington State's climate is characterized by wet, mild winters and drier, warmer summers, especially west of the Cascades. The persistent moisture and rainfall can lead to mold, mildew, and moss growth on asphalt shingles, which can degrade the material and compromise its protective qualities. Frequent rain and wind can also cause shingles to lift or become dislodged. While less common than in other regions, hail can occur, causing impact damage. Proper ventilation and material selection are key to managing moisture and ensuring the longevity of your asphalt shingle roof in this environment. We assess your roof for wear and recommend solutions suited for Washington's conditions.
