This Lynnwood home had an aging asphalt roof covered in moss and organic growth, plus an under-ventilated attic with visible mold on the roof sheathing. RoofSmart tore off the old roof down to the deck and installed a new Owens Corning Duration roof in Onyx Black across roughly 2,060 sq ft (11 roof planes, 6/12 and 10/12 pitch). Scope of work: - Tear-off of one layer of roofing and inspection of the deck, with sheathing replaced where needed - Owens Corning synthetic underlayment, ice & water shield at valleys and penetrations, and starter course at eaves and rakes - 26-gauge metal drip edge and "W" valley flashing - New silicone/metal pipe boots and matching hip & ridge caps - Attic ventilation upgrade: 14 new ventilated bird blocks with baffles, externally baffled ridge vent, old static and gable vents blocked, and new dedicated bath fan vents - Attic mold remediation - 3 permanent stainless steel safety anchors - Carpentry repair of rotten trim at the base of a backyard porch post Because the ventilation was brought up to code, the roof qualifies for the Owens Corning Platinum Protection warranty (50-year material + workmanship), backed by RoofSmart's lifetime workmanship warranty. Completed April 2025.
