Look for signs like sagging areas, dark stains on ceilings, or increased indoor moisture for deck rot. For granule loss, check gutters for excessive granules or notice bald spots on shingles. Seattle's damp climate accelerates these issues, so we recommend annual inspections, especially after heavy rain seasons.

We recommend impact-resistant asphalt shingles with algae resistance for durability against rain and moss, and proper ventilation systems to reduce moisture buildup that causes rot. For severe cases, we may suggest synthetic underlayment or metal roofing options that handle Seattle's precipitation and wind effectively.

Act promptly—these issues can worsen rapidly here due to frequent rain. Minor granule loss might allow a season, but deck rot requires immediate attention to prevent structural damage. We offer emergency assessments and can often schedule repairs within days to protect your home from further water intrusion.
