What Seattle homeowners should know
Seattle's mild, wet marine climate means long rainy seasons rather than extreme heat or cold. Moss, rot and mold are the region's signature home problems, so roofs, gutters and crawl spaces need regular attention.
The area faces earthquake risk from the Cascadia subduction zone and local faults, and hillside homes can have drainage and landslide problems in wet winters. Air conditioning was once rare, but the record June 2021 heat dome made heat pumps a popular upgrade.
