Home insurance carriers are now using satellite and drone imagery to scan roofs for algae, moss, and lichen, then sending homeowners a 30-to-60-day notice to clean the roof or lose their policy. These insurance roof cleaning jobs are deadline-driven, not price-shopped, so they close fast and pay well — if you do them right. Winning them comes down to five things: understand the trend, use the ARMA-approved soft wash process (never a pressure washer), document the job to insurance standards with timestamped before-and-after photos and a PDF report, build in-person referral relationships with local insurance agents, and price for the value you deliver. Done correctly, you are not a cleaning company anymore — you are the contractor protecting a homeowner’s coverage.
I will be honest about why I am the one writing this: I have run exterior cleaning operations — pressure washing and soft washing — for over 25 years, and insurance roof cleaning is one of the fastest-growing categories I have seen in that time. I recently watched a virtual call come in from a homeowner in my own neighborhood whose insurance company threatened to cancel his policy if he did not get his roof cleaned. That is not a one-off anymore. It is a structural shift in how carriers underwrite, and the contractors who get set up for it now are going to own this work in their market. Here is exactly how to capture it.
Insurance companies have gotten aggressive, and they are using satellite imagery and drone technology to inspect roofs without ever sending a person to the property. When their software spots black streaking, algae, moss, or any biological growth, the homeowner gets a letter — sometimes with as little as 30 days to fix it before the policy is canceled or non-renewed. This is happening at scale across humid and high-risk states like Florida, Georgia, the Carolinas, the Gulf Coast, California, and the Pacific Northwest, and it is accelerating every year as aerial-inspection software gets cheaper and more carriers adopt it.
The black streaks the software is flagging are not dirt. They are Gloeocapsa magma, a cyanobacterium that feeds on the limestone filler in modern asphalt shingles and spreads across a roof within a few seasons. Untreated algae and moss hold moisture against the shingle and can shorten a roof’s usable life by an estimated 5 to 10 years, which is exactly why underwriters now read it as deferred maintenance and elevated risk. For a contractor, every one of those letters is a motivated lead with a deadline.
Here is what makes an insurance roof cleaning lead different from your average soft wash call: these homeowners are not shopping around for price. They have a deadline and a real consequence — losing their coverage, which in many cases means defaulting on a mortgage requirement. That completely changes the sales dynamic. They are not calling around for three quotes; they are calling the first professional who answers the phone and can be on-site this week with the right gear and the right documentation.
That urgency is why these jobs justify a different price point than a homeowner who just wants the house looking nice before a cookout. It also means the contractor who answers calls reliably wins. If you are missing calls because you are up on a roof or driving between jobs, you are handing these deadline-driven leads to a competitor. A reliable way to answer or capture every call — whether that is a real receptionist, an answering service, or a business phone built into your CRM — pays for itself on this work alone.
You cannot pressure wash a roof, and the insurance companies and shingle manufacturers make that crystal clear. The Asphalt Roofing Manufacturers Association (ARMA), the governing body for asphalt shingle standards in the United States, states plainly: never use a pressure washer to clean an asphalt shingle roof, because it causes granule loss and very likely premature failure of the roof system. The same position is published by GAF, Owens Corning, CertainTeed, and Malarkey — every major shingle manufacturer is aligned. Pressure washing voids manufacturer warranties, and if a carrier checks for warranty compliance on the cleaning evidence (which they increasingly do), a pressure-washed roof can get the cancellation upheld anyway.
ARMA’s recommended method is a low-pressure chemical application: a roughly 50/50 mix of laundry-strength liquid chlorine bleach (sodium hypochlorite) and water, applied with a sprayer, allowed to dwell on the surface for about 15 to 20 minutes, and then rinsed thoroughly with low-pressure water — generally under 500 PSI at the nozzle, with a bleach-stable surfactant added so the solution clings and dwells on a sloped roof. It does not matter whether your setup is gas, electric, or a pump-up sprayer; what matters is that you are applying chemistry, not blasting the surface. You spray it on, let it dwell, and rinse it off at low pressure. That is soft washing in a nutshell, and it is exactly the process insurance companies are looking for.
This is where a lot of contractors drop the ball even when they do the work correctly. The insurance company does not just want a clean roof — they want proof, and they have to have it. That means timestamped before-and-after photos tied to the property address and the customer’s information, inspection notes on the condition, and a professional PDF report the homeowner can forward directly to their insurance agent or underwriter. Phone photos texted to a customer do not cut it for insurance purposes. A timestamped, formatted inspection report does.
On the All-American side, we run this through QuoteIQ, and the way it handles job documentation is exactly what these jobs require: before we touch the roof, we generate an inspection report with QuoteIQ Cam — photos of the current condition and notes, all timestamped and tied to the customer record. After the job, the completed report is generated with before-and-after photos and job details, and it produces a clean PDF the homeowner can email straight to their carrier or download from the customer portal. I am not here to sell you on the software, though. Whatever system you use, the point is the same: documentation has to be dialed in. If you can hand a homeowner that kind of paperwork when the job is done, you are not just a pressure washing company anymore — you are a professional service that protects their home and their insurance coverage. That is a different conversation, and it justifies a different price.
Here is the part most contractors will not do, which is exactly why the ones who do are going to own this in their market. You have to go find the local insurance agents and talk to them in person — not an email, not a postcard. Pick up the phone, walk into the office, and introduce yourself. Every independent insurance agent in your area has clients getting these letters right now, and most of them do not have a go-to roof washer they refer people to. You want to be that name.
When you walk in, the pitch is simple. Something like: “Hi, I’m Mike with All-American, and we specialize in soft washing roofs. I know you’re probably seeing a lot of clients get flagged for algae and growth on their roofs. We use the ARMA-recommended process — no pressure washing — which protects the shingles and keeps the manufacturer’s warranty intact, and we provide a full documented inspection report with timestamped before-and-after photos your clients can send directly to the underwriter. I’d love to be the company you refer them to.” You are not selling cleaning; you are solving a problem the agent already has and making their job easier. Leave them something with your contact information and a line about the ARMA-approved process, then work your whole market, office by office. An agent who refers you two or three jobs a month is worth more than any ad you could ever run.
Price these jobs according to the value you are delivering, not as a commodity wash. A homeowner trying to save their insurance policy is not the same customer who wants the house looking nice before a party — you are protecting their coverage, their mortgage, and their peace of mind, so price it like that. In most markets a properly soft-washed and fully documented roof on a typical 2,000-square-foot house runs in the $400 to $900 range depending on slope, access, and how heavy the biological growth is, while the chemistry cost is usually under $40 and crew time is half a day or less for a two-person team. Factor your documentation process and professionalism into that number.
There is also a recurring upside most contractors miss. A soft wash treatment typically holds for several years, and the customer who hired you to save their policy is the same one calling you in 12 to 18 months for the house wash, the driveway, the patio, and the rest of the exterior. Insurance roof cleaning is not just a service — it is a door-opener for the rest of the route, which is another reason to treat each job as the start of a relationship and price it as a professional, not a low bidder. Automated follow-up and review requests after the job turn one insurance lead into reviews and repeat work.
For most carriers right now, no — they do not require a specific certification from the people doing the work. What they care about is the process and the documentation. That said, if you have gone through formal soft wash training and hold a recognized certification, it is one more credibility marker when you are standing in front of an insurance agent or a homeowner. It is not required, but it separates you from someone who just bought a soft wash setup last month, and on this kind of work, every bit of professional credibility helps you win the job and hold your price.
Insurance-required roof cleanings are a growing category, and they are only going to keep growing as carriers get more aggressive with aerial inspections every year. That means a lot more of these letters are coming down the pipeline, and the homeowners receiving them are motivated, deadline-driven buyers. Get your rig set up for proper soft washing, get your documentation dialed in, build relationships with the insurance agents in your market, and price for the value you deliver. Do that, and you will be the contractor those agents and homeowners call first — and you will make more money doing work that genuinely protects people’s homes.
Yes. Home insurance carriers across humid and high-risk states — Florida, Georgia, the Carolinas, the Gulf Coast, California, and the Pacific Northwest among them — now use satellite and drone imagery to scan insured roofs for algae, moss, and lichen. When the software flags biological growth, the carrier sends the homeowner a notice with a deadline, often 30 to 60 days, to clean the roof and send proof or risk having the policy canceled or non-renewed. The practice is expanding quickly as aerial-inspection software gets cheaper, which is creating a fast-growing category of insurance roof cleaning jobs for soft wash contractors.
No. You should never pressure wash an asphalt shingle roof. The Asphalt Roofing Manufacturers Association (ARMA) states that a pressure washer causes granule loss and very likely premature failure of the roof system, and every major shingle manufacturer — GAF, Owens Corning, CertainTeed, and Malarkey — agrees. Pressure washing also voids manufacturer warranties, and carriers increasingly check the cleaning evidence for warranty compliance. If a roof was pressure washed, the cancellation can be upheld anyway and the roof has to be re-cleaned the right way. The only accepted method is low-pressure soft washing.
ARMA recommends a low-pressure chemical application, not mechanical cleaning. The method is a roughly 50/50 mix of laundry-strength liquid chlorine bleach (sodium hypochlorite) and water, applied with a sprayer, left to dwell on the roof surface for about 15 to 20 minutes, and then rinsed thoroughly with low-pressure water, generally under 500 PSI at the nozzle. A bleach-stable surfactant is typically added so the solution clings and dwells on sloped surfaces. This is what the industry calls soft washing — it kills algae, moss, and lichen at the cellular level using chemistry rather than force, without stripping the protective granule layer or voiding the warranty.
Carriers want proof the roof was professionally cleaned. That generally means timestamped before-and-after photos tied to the property address and the homeowner’s information, inspection notes on the roof’s condition, and a professional PDF report the homeowner can forward directly to their insurance agent or underwriter. Casual phone photos texted to a customer usually are not enough. A formatted, timestamped inspection report is what gets a policy reinstated. For contractors, having a system that generates this documentation automatically — before-and-after photos, notes, and a clean PDF tied to the customer record — is what separates a professional service from a guy with a bucket and a hose.
The most effective approach is in person, not email or postcards. Visit the local independent insurance agents in your market, introduce yourself, and explain that you specialize in ARMA-approved soft washing of roofs, that your process protects the shingles and keeps the manufacturer’s warranty intact, and that you provide a full documented inspection report their clients can send straight to the underwriter. Every independent agent has clients getting cancellation letters right now, and most do not have a go-to roof washer, so you are solving a problem they already have. Leave your contact information and work the whole market office by office. An agent referring two or three jobs a month outperforms most advertising.
Price for the value you deliver, not as a commodity wash, because you are protecting the homeowner’s coverage and mortgage, not just cleaning a roof. In most markets a properly soft-washed and fully documented roof on a typical 2,000-square-foot house runs in the $400 to $900 range depending on slope, access, and how heavy the algae and moss growth is. The chemistry cost is usually under $40 and crew time is half a day or less, so the margin is strong — and these deadline-driven customers are far less price-sensitive than a typical house-wash lead. Factor in your documentation, professionalism, and the recurring work that follows when you set your price.
In most cases, no. Insurance carriers generally do not require a specific certification from the contractor doing the work — what they care about is that the correct ARMA-approved process was used and that the job is properly documented with timestamped photos and a report. That said, completing formal soft wash training and holding a recognized certification adds credibility when you are pitching insurance agents or homeowners, and it helps distinguish you from someone who just bought a soft wash setup. It is a useful credential and a trust marker, but it is the process and the documentation, not the certificate, that actually get a policy reinstated.
The black streaks running down an asphalt shingle roof are not dirt — they are Gloeocapsa magma, a cyanobacterium (a type of algae) that feeds on the limestone filler used in modern asphalt shingles. It thrives in humid, shaded conditions and spreads across a roof within a few seasons, often appearing first on north- and west-facing slopes that stay damp longer. Beyond the appearance, the algae and any accompanying moss hold moisture against the shingle, which can accelerate granule loss and shorten the roof’s usable life by an estimated 5 to 10 years. That biological growth is exactly what insurance carriers’ aerial-inspection software is trained to detect and flag.
