Choose your city
Washington's climate, particularly in areas like Seattle, is characterized by significant rainfall throughout much of the year. This means your roof needs to be exceptionally watertight. The presence of moisture can also contribute to mold and mildew growth if not properly managed during installation. The housing stock varies, and ensuring proper ventilation and drainage is paramount, especially with older homes that might have different structural designs. The condition of your existing roof deck is also a key consideration.
Common questions

What is the 25% rule for roofing in Washington?

What is the average cost to have a new roof installed in Seattle?
Providing an average cost for a new roof in Seattle is challenging without a site assessment.

What is the cheapest month for roofing in Washington?
While roofing can be performed year-round in Washington, you might find slightly more availability and potentially better pricing during the drier months, like late spring or early summer. However, prioritizing a quality installation that can withstand Washington's persistent moisture is more important than trying to time the market for cost savings.
