We’d like to say that we can install any roof in the world, which may be true. However, in Portland, Oregon, ~90% of all new roof installations are asphalt shingles and for good reason. Asphalt shingles have the best longevity in Portland’s seasonal climate. When the temperature is 50 degrees in the morning, and swings up to 95 degrees in the afternoon, you need a product that can handle that constant expanding and contracting, and nothing works better than asphalt shingles. Asphalt shingles are priced competitively compared to other products, and are architecturally appealing to the eye– they look nice and add dimension to the exterior of the home.
