Snohomish River fog is common October through March, extending the moisture cycle longer than in sun-exposed parts of the county. Moss pressure in shaded river-valley properties is among the highest in our service area. The Snohomish and Pilchuck River valleys also flood: FEMA-mapped flood zones affect roof decisions indirectly through insurance-driven scope reviews. Snow load is 25 psf at low elevations, rising with elevation east of town. SBS-modified asphalt, stainless or hot-dipped fasteners, and strict moss-treatment cadence every two to three years are the spec defaults for this climate.
