Washington's roofs, particularly in the Seattle region, must contend with consistent rainfall, high humidity, and potential for moss growth. Our installation process prioritizes moisture resistance and durability. We begin with a thorough inspection of your existing roof and the underlying structure, checking for any signs of water damage or rot. Compromised roof decking is repaired or replaced to provide a solid foundation. A high-quality waterproof underlayment and robust drip edges are installed to manage water runoff effectively. The new roofing material is then applied using techniques suited to Washington's climate, focusing on shedding water and preventing moisture intrusion. We manage all necessary permits and inspections required by local authorities in Seattle and surrounding areas, ensuring your new roof meets all code requirements and stands up to the elements.
