Common questions, honest answers.
How often should I have my roof cleaned across Greater Clark County?
Every 1–2 years for most homes. Moss and algae grow year-round in Western Washington, and waiting longer than two years usually means heavier buildup and longer treatment time. Homes under heavy tree cover or with north-facing roofs may need annual cleaning. AWP Exterior Cleaning recommends scheduling roof cleaning before moss lifts shingle edges and accelerates granule loss.
Is soft washing safe for my roof and siding?
Yes. Soft washing uses low pressure — about the same as a garden hose — and relies on cleaning solution dwell time to break down growth. High-pressure washing strips granules off shingles, forces water behind siding, and voids most roof warranties. Soft washing is the only method recommended by shingle manufacturers. AWP Exterior Cleaning uses soft washing on all roofs and siding across Greater Clark County.
Do you need a pesticide license to clean roofs in Washington?
Yes. Any company applying moss treatment or moss-control products in Washington must carry a commercial pesticide applicator license from the Washington State Department of Agriculture. AWP Exterior Cleaning's technicians are licensed in both Washington and Oregon, apply EPA-registered products, document application rates, and follow state re-entry intervals.
How long does a typical house wash take?
Most single-family homes take 2–3 hours depending on square footage and number of stories. Two-story homes take longer than single-story ranches because AWP uses extension poles and works more carefully around upper windows and eaves. The crew cleans windows, eaves, and fascia as part of the house wash.
How do you price your services?
Pricing is based on square footage for house washing and roof cleaning, linear footage for gutters and fences, and per-window count for window cleaning. AWP Exterior Cleaning can give accurate pricing over the phone if you know your home's square footage, or the crew will measure on-site during a free estimate.
Do I need to be home during the service?
Not required as long as AWP has access to the exterior and a way to reach you by phone. The crew will send before-and-after photos when the job is done. If they're cleaning interior windows or need access to a locked gate, someone needs to be home.
