In Seattle's Pacific Northwest climate, moss growth on roofs and excess moisture collection in roofing materials are common signs. Debris accumulation from trees, water retention, and physical damage to shingles are indicators that roof cleaning is needed.

Check for visible debris, leaves, or moss buildup on your roof surface. Inspect gutters for clogs or organic material. Look for dark stains or discoloration on shingles. Verify downspouts are draining properly and check for overhanging tree branches touching the roof.

Typical roof cleaning services include removal of loose debris, moss treatment, and moss removal. Additional services may include gutter cleaning, ground debris removal, and application of moss-inhibiting treatments. Some companies also offer yard debris cleanup.
