Aerial and ground documentation — the same view your carrier is looking at.
Your roof may be reviewed from above.
Some insurers review roof condition using property inspections, aerial imagery, or satellite photography. Visible moss, algae, lichen, staining, and debris may be noted during that review — though standards vary by carrier, by policy, and by property.
Organic growth can be interpreted as a maintenance concern even when the roof underneath remains serviceable. If you have received a written notice, read it closely and confirm the required documentation and the deadline directly with your agent or carrier. We don’t interpret policy language and we don’t speak to coverage — that conversation belongs with them.
What we can do is remove the visible growth with a method appropriate to your roof material, photograph the roof before and after, and give you a written record of the work performed. You decide what to send.
We are licensed and carry $1,000,000 in liability coverage. A certificate of insurance is available on request if your carrier, HOA, or property manager wants one on file.
Most Peninsula notices come from a handful of carriers.
Homeowners across Burlingame, Millbrae, Hillsborough and San Mateo have brought us roof-condition letters from State Farm, Farmers, Allstate, USAA, CSAA/AAA, Mercury, Liberty Mutual and the California FAIR Plan. The wording differs, but the pattern is the same: an aerial or satellite image, a note about moss, algae, debris or staining, and a deadline to remediate or provide evidence the roof has been addressed.
Deadlines we’ve seen run from 30 to 75 days. That is enough time if you move now, and not much if you wait for a quote from three companies. We schedule notice work ahead of routine jobs and can usually be on the roof within the week.
What to do in the first 48 hours: read the letter and note the exact deadline and what they’re asking for (cleaning, photos, an inspection, or all three); call your agent and confirm what documentation they want back; then call us. We’ll look at the roof, quote it, and tell you honestly if what they’re flagging is growth we can remove or a condition that needs a roofer instead.
We don’t interpret policy language and we can’t promise an outcome. What we can do is remove the growth properly, document it clearly, and get it done inside your deadline.
Four services.
Obsessively executed.
Common compliance calls: non-renewal notices citing roof condition, pre-inspection cleaning before a scheduled carrier visit, HOA architectural compliance, and pre-sale roof documentation.
Roof Cleaning & Moss Removal
Moss, algae, lichen and the black streaks on shingle, tile and cedar roofs — removed at the root with low-pressure soft washing. Never a pressure washer on a roof.
- Moss, algae & black streak removal
- Tile, shingle, cedar & slate

House Washing
Exterior house washing for stucco, wood, Hardie and painted siding. Green algae, black mildew and roofline grime gone — the result of a power wash without the damage.
- Stucco & siding cleaning
- Mildew, algae & cobweb removal
- Add exterior windows
Driveway & Patio Pressure Washing
Hot-water pressure washing that lifts oil, algae, moss and years of grime from concrete, brick, pavers, exposed aggregate and stone — without stripping the surface.
- Driveways & walkways
- Patios, decks & pool decks
- Brick & paver restoration
Gutter Cleaning
Gutters cleared by hand, every downspout flushed until it runs clear, and a look at the hardware for sagging, pulled spikes or separated seams. Book before the rains.
- Full debris removal
- Clogged downspouts cleared
- Damage inspection report

Soft Wash Roof Cleaning across the Peninsula.
A clear, documented response.
1. Estimate, reviewed by Nick. We look at the visible condition, the roof material, access, and the specific concern described in your notice. Send a photo of the letter if you have one — the deadline shapes the schedule.
2. Before documentation. Photos from multiple angles, including every area your notice calls out, captured before anything is touched.
3. Soft wash treatment. Low pressure and detergent, matched to your roof material, killing moss, algae, and lichen at the root. We never pressure wash a roof — high pressure can void manufacturer warranties and cause the very damage a carrier worries about.
4. After documentation and service record. Matching after photos where access and conditions allow, plus a written description of the work performed.
5. Your file. You receive the photo set, the service record, and our business and insurance information. Acceptance and policy decisions remain entirely with your carrier.
Asked constantly.
Will roof cleaning guarantee my policy continues?
No company can guarantee an insurance decision, and you should be wary of any that says otherwise. Cleaning addresses visible moss, algae, lichen, and debris; photos and a service record document the work. Confirm submission requirements and deadlines directly with your agent or carrier.
What if my insurer cancels anyway?
Your carrier may still request repairs, a further inspection, or additional documentation. We provide the project photos and service record we captured, but we cannot guarantee acceptance, reinstatement, renewal, or pricing.
How quickly can you schedule?
Roof-condition notices are deadline-driven, so we prioritise them. Share the date on your letter with your estimate request and we will confirm the earliest realistic timing. Most quotes go out within 24 hours.
Do you provide photos I can send my agent?
Yes, at no extra charge. Before-and-after photos plus a written description of the work performed. What you submit, and how, is up to you.
Will pressure washing void my roof warranty?
High pressure can, which is exactly why we do not use it on roofs. We soft wash only: low pressure and detergent, matched to the material and aligned with published guidance against high-pressure roof washing.
Are you licensed and insured?
Yes. Licensed, and carrying $1,000,000 in liability coverage. We provide a certificate of insurance on request rather than posting the document publicly.
How long does the cleaning last?
Soft washing kills growth at the root rather than stripping the surface, so results typically hold 2 to 3 years on the Peninsula. Heavy tree canopy shortens that. If your carrier reviews annually, a maintenance schedule keeps you ahead of the next notice.
My insurance company sent a letter about my roof. What do I do first?
Find the deadline and write it down. Then call your agent and ask exactly what they need back: cleaning only, before-and-after photos, a contractor’s statement, or a re-inspection. Then call us. Most Peninsula roof notices are about moss, algae or debris, which we can remove and document within the week. If the letter is about roof age or damage, you need a roofer, and we’ll say so.
Which insurance companies send roof cleaning notices?
On the Peninsula we’ve handled notices from State Farm, Farmers, Allstate, USAA, CSAA/AAA, Mercury, Liberty Mutual and the California FAIR Plan. Many now review roofs with aerial or satellite imagery rather than a site visit, so a roof can be flagged without anyone having set foot on the property.
How much time do I have?
Typically 30 to 75 days from the date on the letter, but it varies by carrier and it is written in the notice. Treat the deadline as the day the photos need to be in your agent’s hands, not the day the cleaning happens.
Does this apply to the California FAIR Plan?
Yes. FAIR Plan policies carry their own maintenance requirements, and with so many Peninsula homes moving onto the FAIR Plan, roof-condition notices from it are increasingly common. We treat them the same way: appropriate cleaning, documentation, written service record.
Let's get the growth off your roof — safely.
Estimate request only — no job is booked and no payment is collected. Send us the notice deadline and we will tell you honestly what we can do and when. Carrier acceptance is not guaranteed.
