Seattle Roofing FAQs
Why is moss growth particularly problematic for Seattle roofs?
Moss retains moisture against the roof surface 24/7, preventing drying and accelerating material breakdown. Its root-like structures can work into seams and penetrate membranes, creating pathways for water intrusion that are difficult to detect until significant damage occurs.
How often should commercial roofs be inspected in the Seattle area?
We recommend semi-annual inspections—once in late fall to prepare for winter rains, and again in early spring to assess any wet season damage and address moss growth before the drier summer months arrive.
What’s the most common cause of roof failures in the Northwest?
Inadequate drainage stands as the primary culprit. When water ponds or moves slowly off roofs, it finds every minor imperfection in membranes and flashings. Proper slope and functioning drainage are more critical here than in many other climates.
Are some roofing materials better suited for Seattle than others?
Yes, we typically recommend fully adhered membrane systems with reinforced seams, light-colored surfaces to maximize limited drying opportunities, and materials with inherent resistance to biological growth that plagues many Northwest roofs.
