Roof shingle types in Washington
Last updated: September 24, 2026
ChoiceRoofingTeam works across Washington State, including the major hubs of Seattle and Kirkland. Washington's climate is characterized by mild, wet winters and dry, warm summers, with significant rainfall in the western half. This persistent moisture impacts roofing materials and necessitates durable, water-resistant solutions.

In Washington, especially west of the Cascades, the constant moisture and moss growth can degrade roofing materials over time. Asphalt shingles are common, but consider options with algae-resistant treatments. Metal roofing is a durable alternative, effectively shedding water and resisting moss. Licensing in Washington is handled at the state level, requiring contractors to be registered. When selecting a provider, verify their registration and look for experience with the specific challenges of Washington's damp environment.
Common questions
What shingle types are best suited for Washington's rain?
For Washington's wet climate, consider asphalt shingles with algae-resistant treatments to combat moss growth. Metal roofing is also a highly effective option for shedding water efficiently and resisting the moisture common in the state. Impact-resistant shingles can also offer added protection.
How do shingle choices impact costs in Seattle?
The selection of shingle type directly influences the final cost of a roofing project in Seattle. Higher-performance shingles designed for longevity and resistance to moisture and algae will generally be more expensive than basic asphalt options, reflecting their enhanced durability.
What are the best shingle options for moss prevention?
To prevent moss growth in damp climates like Washington, opt for asphalt shingles with copper or zinc granules embedded in them, which inhibit moss development. Metal roofing is also naturally resistant to moss and algae, making it a low-maintenance choice.
Are there specific licensing requirements for roofers in Washington?
Yes, roofing contractors in Washington State must be registered with the Department of Labor and Industries. This registration ensures they meet certain standards for consumer protection. Always verify a contractor's registration before proceeding with any roofing work.
What is the lifespan difference between shingle types?
Asphalt shingles typically last 15-30 years, with architectural styles lasting longer than three-tab. Metal roofing systems can last 40-70 years or more. The climate and maintenance also significantly affect how long any shingle type will perform.
Which shingle type is most resistant to wind?
Architectural asphalt shingles generally offer better wind resistance than three-tab shingles due to their heavier weight and layered design. For maximum wind resistance, specialized impact-resistant shingles are available, and metal roofing systems are also known for their wind resilience.
