Roofing in Washington: What You Need to Know

Western Washington roofs endure 6-8 months of near-continuous rain, making moisture management the number one priority. Moss and algae growth is extremely aggressive. Eastern Washington is the opposite - hot, dry summers with wildfire risk and cold, snowy winters.

Washington requires roofing contractors to be registered with the Washington State Department of Labor and Industries (L&I). Contractors must carry a surety bond, liability insurance, and workers' compensation.
