ARMA-recommended soft wash roof treatment that safely removes black streaks, algae, and moss — and extends your roof's life.
Kill the algae that's eating your roof. Restore curb appeal. Protect your warranty.
Those dark black streaks on your roof aren't just ugly — they're alive. Gloeocapsa Magma is a cyanobacteria (algae) that feeds on the limestone filler in asphalt shingles. Left untreated, it shortens your roof's lifespan, voids manufacturer warranties, and can trigger higher homeowner's insurance premiums. Our ARMA (Asphalt Roofing Manufacturers Association) recommended soft wash system kills it at the root and restores your roof's appearance.
We never use high-pressure on roofs. High-pressure washing blasts off the protective granules from asphalt shingles, dramatically shortening roof life. Our soft wash system uses low pressure (less than 500 PSI) with a professional sodium hypochlorite-based solution that kills all biological growth — algae, moss, lichen, and mold — without damaging a single shingle.

Straight answers about soft wash roof cleaning, insurance requirements, and more.
Black streaks on roofs are almost always caused by Gloeocapsa Magma — a type of algae that thrives in Florida's humid climate. The algae feeds on the limestone aggregate in asphalt shingles. It spreads from shingle to shingle and will continue growing until treated.
No — when done correctly, soft washing is safer than pressure washing and does not damage shingles. We use a low-pressure rinse (under 500 PSI, which is less than a standard garden hose nozzle) combined with a professional cleaning solution. This is the method recommended by the Asphalt Roofing Manufacturers Association (ARMA).
Results typically last 2–4 years in Florida's climate. We offer a post-treatment spray that can extend protection by an additional year.
We thoroughly pre-wet all landscaping before applying roof cleaning solution. We also clean your gutters of any debris that washes down during the cleaning process. Our solutions are biodegradable and safe once diluted and rinsed.
Yes — this is one of the most common reasons our customers call us. A clean roof certificate is often required by insurance companies in Florida. We can typically schedule cleaning within a few days and document results for your insurer.

Four reasons Tampa Bay property owners pick us for this service specifically.
We follow the Asphalt Roofing Manufacturers Association protocol exactly — low pressure, approved chemistry, no shingle damage. Your manufacturer warranty stays intact.
Florida carriers are sending non-renewal letters faster than ever for dirty roofs. We schedule insurance-deadline jobs within 48–72 hours and provide photo documentation for your adjuster.
Our sodium hypochlorite blend is calibrated to Florida humidity conditions. We kill the root, not just the surface stain — roofs stay clean 3–5× longer than pressure-wash alternatives.
Clay and concrete tile roofs are common from Palm Harbor to Tampa. We calibrate pressure specifically to avoid cracking tiles or dislodging mortar beds. This is specialist work — we do it every week.
Florida's subtropical climate is the perfect environment for Gloeocapsa Magma — the black-streak algae that feeds on the limestone filler in asphalt shingles. Humidity above 60% for most of the year, daily summer rain from June through October, and mature oak canopy in neighborhoods like Countryside (Clearwater), Innisbrook (Palm Harbor), and Seminole Heights (Tampa) accelerate growth dramatically. Roofs in these areas often need soft washing every 2–3 years; shaded lots sometimes need it annually.
Most HOA-managed communities in Tampa Bay — particularly in Westchase, Fishhawk, Trinity, and Riverview — have documented aesthetic requirements for roof cleanliness and will issue violation letters with firm deadlines. We prioritize HOA-deadline jobs and provide before/after photos your board can file.
We service roof cleaning across:
"Our insurance company gave us 30 days to clean the roof or lose coverage. JAB came out the next morning, did the whole house in about two hours, and sent photos right to my adjuster. Roof looks brand new."
"I was worried about pressure damage on our tile roof — JAB was the only company that explained exactly what pressure they use and why. No broken tiles, no dislodged mortar. Just a clean roof."
"Our HOA sent a letter with a 10-day deadline. JAB fit us in, did the soft wash, and the results are ridiculous. Neighbors have been asking who we used."
Pricing varies by roof pitch, access difficulty, and how heavy the staining is. Estimates are always free and written.
| Scope | Typical Range |
|---|---|
| Single-story, under 1,800 sq ft | $349 – $449 |
| Single-story, 1,800–2,800 sq ft | $449 – $649 |
| Two-story or 2,800+ sq ft | $649 – $950 |
| Tile roof (any size) | Quoted after site visit |
What affects the final price: property size, surface condition, access difficulty, and which combination of services is bundled. Every quote is free and written — no surprise upcharges on-site.
Straight answers to what Tampa Bay homeowners actually ask us about roof cleaning.
No — when done correctly at under 500 PSI with the right chemistry, soft washing is safer than pressure washing and explicitly recommended by the Asphalt Roofing Manufacturers Association (ARMA). High-pressure washing is what damages roofs — it strips granules, voids warranties, and causes leaks. We never put high pressure on a roof.
In Tampa Bay's humid climate, soft wash results typically last 2–4 years before visible algae returns. Roofs under heavy tree canopy or on the north-facing side of homes may see faster regrowth. We offer an optional post-treatment spray that extends protection roughly another year.
Yes — insurance-deadline roof cleanings are one of the most common reasons Tampa Bay homeowners call us. We can schedule within 48–72 hours and provide time-stamped before/after photos for your adjuster. Send the letter and we'll work backward from the deadline.
Not usually. We need access to an outdoor spigot and a clear path to the roof. If you have gates or a dog, we just need to coordinate access ahead of time. Most homeowners are at work when we complete the cleaning.
We pre-wet all landscaping before applying any solution, rinse thoroughly after, and use biodegradable surfactants that dilute quickly once on the ground. Pets should be indoors or in the garage during treatment and for about an hour after the final rinse.
Gloeocapsa Magma — a hardy cyanobacteria that feeds on the limestone aggregate in asphalt shingles. It spreads via airborne spores and colonizes in warm, humid environments. Florida is ideal for it. Left untreated, it retains moisture against the roof deck and can shorten shingle life by years.
Yes. Clay and concrete tile roofs are common across Tampa Bay and require even lower pressure plus specialized technique to avoid cracking tiles or dislodging mortar beds. We work on tile roofs every week — tell us during the estimate and we'll scope it appropriately.
