Frequently Asked Questions About Roof Cleaning

Do you use high pressure or pressure water on roofs?

No. We do not use high pressure on asphalt shingles. Our method is gentle: debris removal with soft brushes and blowers, plus an eco-friendly moss/algae treatment to stop regrowth.

What’s included in a standard roof clean?

Surface debris removal (needles, leaves), moss lift with soft brushing, targeted treatment for moss/algae, and a final tidy. Note: interior gutter cleaning and downspout flush are separate services you can add.

How often should I clean my roof in Washington?

Typically once a year. Homes under heavy trees or constant shade may need service every 6–12 months with periodic treatment.

Is the moss treatment safe for plants and pets?

We use eco-friendly solutions and follow best practices (pre-wet/rinse landscaping as needed). Keep pets off treated surfaces until they’re dry.

Do you walk on the roof?

We minimize walking. When access requires it, we use proper footwear, roof pads, ladders/stabilizers, and fall-protection to avoid damage and work safely.

Can I use a wire brush or pressure washer myself?

We don’t recommend it. A wire brush or aggressive scrubbing can remove shingle granules; pressure water shortens roof life. Our soft-brush + treatment approach is roof-safe.

Will everything look clean the same day?

Loose growth is removed during service. Remaining roots/spores die after treatment and brown out; light residue often releases with weather over the next 2–6 weeks.

Which roof types do you clean?

Asphalt shingles, metal, and others. Methods vary by material to protect finishes and warranties. We never use high pressure on shingles.

Can you combine roof cleaning with other services?

Yes. Popular bundles: gutter cleaning (inside & downspouts), soft washing for siding/trim, and window washing. Bundling saves time and improves overall results.

How do you price roof cleaning?

Based on roof size/complexity, pitch, access, moss level, and add-ons (gutters, treatment, exterior gutter wash). Get a fast quote here: Request a free estimate.
