For this project we installed a Certainteed Landmark PRO shingles roofing system and got rid of the entire old roofing. We opted to go with the Landmark Pro shingles due to their great durability and quality. Since we used the Landmark Pro shingles we also decided to go with the Shadow Ridge as the hip and ridge accessory shingles for a perfect match. We used the Certainteed Winterguard due to its protective value during the subsequent stages of the roof replacement.
