Choose your city
Washington State's climate, characterized by persistent rain, especially in the western parts around Seattle and Bellingham, and cooler temperatures, demands roofing materials that can withstand moisture and temperature swings. EPDM, a single-ply rubber membrane, excels in these conditions due to its seamless application, which significantly reduces the risk of leaks. It's also flexible in cooler temperatures, preventing brittleness and cracking. When considering EPDM installation, it's important to ensure your chosen provider understands the specific nuances of Washington's building codes and has experience with proper installation techniques that maximize water runoff and durability.
