Washington's climate is characterized by significant annual rainfall, particularly in the western part of the state, and moderate temperatures. This persistent moisture demands roofing systems that are exceptionally watertight. Rolled roofing, often utilized on lower-sloped roofs, requires meticulous seam sealing and application to prevent leaks and water damage. The underlayment's performance is critical in managing moisture, and proper flashing around vents, chimneys, and edges is essential to divert water away from the building's structure. The longevity of the installation is directly tied to its ability to resist prolonged damp conditions.
