Most Snohomish County calls start the same way: a ceiling stain in a 20-year-old composite roof after the first real rain of October. We inspect, photograph, and tell you plainly whether the roof needs a repair, a section replaced, or a full tear-off.

Snohomish County averages well over 35 inches of rain a year, and the tree cover from Monroe to Arlington keeps roofs damp and shaded — the exact conditions moss needs.
Wind-lifted ridge caps after a Puget Sound squall, failed pipe-boot seals, valley leaks where two gables meet, moss lifting shingle edges on north-facing slopes, and rusted flashing around chimneys on older Everett and Edmonds homes. Most of these are repairs, not replacements — we'll say so if that's the case.
Under heavy fir and cedar cover, moss wicks water sideways under the shingle course and rots the decking underneath. We treat, brush (never pressure-wash), and where needed install zinc strips at the ridge so the problem doesn't come back in two winters.
If the damage is localized and the shingles still have granules and flexibility, we repair. If the deck is soft, the shingles are curling across whole slopes, or you're on your third patch in three years, replacing is the cheaper answer over ten years. We give you both numbers.
We climb it, photograph it, and give you an itemized estimate — no pressure. Call (425) 783-9543 or email info@pacificcoastroofing.com.
