Seattle sits in a marine west coast climate (Köppen: Cfb).
Cool temps. Constant moisture. Long stretches of drizzle. That means: Moss and algae grow fast. Moisture gets trapped under old shingles. Decking rots if ventilation’s off. Flashing fails during long wet spells. Wind gusts from winter storms peel weak shingles. Seattle roofs rarely fail in summer. They fail after eight months of wet chill.

Seattle labor isn't cheap. Moss removal and prep add cost too.
Washington requires a registered roofing contractor — no exceptions.
Seattle requires:
Permit for all re-roofs
Proper ventilation for moisture control
City inspections
If someone says “no permit needed,” that’s your sign to walk away.
Moss forms under misaligned shingles
Decking stays wet too long
Underlayment wrinkles from moisture
Winter rain exposes amateur mistakes overnight
DIY roofs here rot early. It’s that simple.
