Washington's climate presents unique challenges for roofing systems, characterized by prolonged periods of precipitation and moderate temperatures. Materials must be chosen for their resistance to moisture, UV degradation from intermittent sun, and the potential for wind uplift common along the coast and in the Puget Sound region. For Seattle and Vancouver, specifying high-quality underlayment and robust shingle installation, often including a secondary water barrier, is critical to prevent leaks and prolong roof life. Compliance with Washington's stringent building codes, which emphasize water shedding and wind resistance, ensures a secure and long-lasting installation.
Common questions
What is the 25% rule for roofing in Washington?
In Washington, the 25% rule generally dictates that if more than a quarter of a roof's surface is covered by multiple existing layers of shingles, a complete tear-off to the deck is required. This ensures the structural integrity of the roof and adherence to safety standards prevalent in the state.
