Roof Cleaning & Moss Removal | Wash Works Sacramento

› Quick Answer

Roof cleaning uses a soft-wash method with biocidal detergents that kill algae, lichen, and moss at the root — without ever applying high pressure to your shingles. ARMA-approved. Most roofs take 2–4 hours. Free same-day quotes — call (916) 404-0288.

How It Works

Surface assessment

We inspect the roof for damaged shingles, sensitive flashing, and runoff paths into landscaping before any solution touches the surface.

› Step 1

Pre-treat & protect

Plants, gutters, and downspouts get pre-rinsed. Sensitive landscaping is covered or wetted down before application.

› Step 2

Soft-wash application

Low-pressure delivery of an algaecide solution coats the roof. The chemistry kills algae and moss at the spore level — no granule loss, no shingle damage.

› Step 3

Rinse & inspect

We rinse the roof gently and walk the property with you. Most algae lifts visibly during the wash; remaining staining clears over the next 2–4 weeks.

› Step 4

Yes — high pressure strips granules from asphalt shingles, voids most warranties, and shortens roof life by 5+ years. Wash Works uses soft wash (under 100 PSI) on roofs. ARMA-approved method.

Most algae lifts visibly during the wash. Heavy staining and dead moss clear over the next 2–4 weeks as the killed organisms dry out and rain rinses them away.

Not at the dilutions we apply. We pre-rinse landscaping before, during, and after to dilute any runoff. Our solutions are biodegradable.

Most Sacramento roofs benefit from a soft wash every 3–5 years. North-facing slopes and roofs under tree cover may need it more often.
