Roof Cleaning in Naples — What 34 Years Has Taught Us

Almost every Naples roof eventually develops the same problem: dark streaks, black patches, or full sheet-staining caused by Gloeocapsa magma — a hardy algae that thrives in Florida’s heat, humidity, and shade. Lichen and moss come next, especially in shaded areas and near tree cover. Left untreated, these organisms eat into roofing material, shorten roof lifespan by years, and trigger HOA letters.

The roof cleaning business has changed a lot since 1992. Back then most operators used pressure washers because that’s all there was. We did too — until manufacturer warranty data came out showing what high-pressure water actually does to tile and shingle. Today we soft wash exclusively. The chemistry kills the algae at the root. The water pressure stays low enough to never displace granules, lift tiles, or void a warranty. That’s the difference between a clean that lasts 2-3 years and a clean that damages the roof.

The Roof Cleaning Method That Doesn’t Void Your Warranty

GAF, CertainTeed, Owens Corning, and most tile manufacturers explicitly approve soft wash cleaning. They explicitly do NOT approve pressure washing. If a roof cleaner shows up with a pressure washer and aims it at your shingles, your warranty is gone. Every job we do is documented soft wash — we can provide written method documentation if your warranty requires it.

We work all three of the roof types you’ll find in Naples: concrete and clay tile (the bulk of the market), asphalt shingle (most newer subdivisions), and metal (less common but increasingly specified on new builds). Each one needs slightly different chemistry concentration, dwell time, and rinse pressure. After 5,000+ jobs we know what works on what — and just as important, what damages what.

A typical Naples roof needs cleaning every 2-4 years, depending on shade, tree cover, and proximity to the coast. Marco Island roofs and homes in Pelican Bay’s tree-shaded sections tend to need it sooner. Fully sun-exposed roofs in inland Naples can sometimes go 4+ years. We’ll tell you on the on-site quote whether your roof is at the right interval — and if it isn’t, we’ll tell you that too.



Why Choose 321

Why Naples Has Trusted Us Since 1992

34 Years. Same Family.

We've been cleaning Naples roofs since 1992. We're not a franchise. We're not a national chain that bought a local name. We're the same Corcoran family operation that started here three decades ago — same number, same standard, same crew.

5,000+ Naples Roofs

There isn't a tile profile, paver pattern, or stain type in this market we haven't seen. That experience matters because the wrong chemistry damages tile. The wrong pressure strips finishes. We know what works on what — because we've done it 5,000 times.

Soft Wash, Done Right

Soft wash uses chemistry, not pressure, to kill the algae and lichen at the root. That's why our cleans last. Pressure washing roofs is faster but ruins them — voids warranties, displaces granules, lifts tiles. We do it the right way, every time.


A Note from the Owner
"

I've cleaned roofs in Naples since before HOAs cared about black streaks. Back then we used pressure washers because that's all there was. Now we soft wash because that's what works without damaging tile. 34 years in the same business teaches you the difference.

Same family. Same number. Same standard since 1992.

Three Roof Types. Three Methods.

Same soft wash chemistry, but the concentration, dwell time, and rinse approach changes per roof type. Here’s what we do on each.

Concrete & Clay Tile

What we do: Apply soft wash solution at lower concentration, longer dwell time. Rinse at very low pressure to preserve the cement matrix and clay surface. Avoid walking on tile where possible — we work from gutter ladders and from above.

Why: Tile is porous and brittle under pressure. The wrong method cracks tiles or strips the protective surface coating. Our method removes algae and lichen without touching the tile structure.

Asphalt Shingle

What we do: Apply soft wash at standard concentration, moderate dwell, then a slow rinse at low pressure. Treat any visible algae streaks (Gloeocapsa magma) directly. Inspect granule loss before and after.

Why: Shingles lose protection when granules wash off. Pressure washing strips them by design. Soft wash leaves them intact while killing the algae underneath.

Metal Roof

What we do: Soft wash with neutral-pH chemistry to protect any factory finish or paint coating. Rinse top-down, paying attention to seams and screws. Treat any oxidation spots separately.

Why: Metal roofs are less common in Naples but increasingly specified on new builds. The wrong chemistry can attack the finish coating. Ours doesn’t.

What Naples Says

What Naples Says About Our Roof Work

"Black streaks were so bad the HOA sent a letter. 321 was out within a week. Roof looked new the same afternoon. Two years later still no algae. They use real soft wash chemistry, not just water pressure."

Mark D.
Naples · Tile Roof Soft Wash

"Three estimates. 321 was middle on price but the only one that explained the chemistry of soft wash and showed proof of insurance without me asking. Easy choice. Job was clean."

Jennifer P.
Estero · Roof Cleaning

"Roof was streaked from one end to the other. Insurance was threatening to drop us. 321 cleaned it Tuesday, took photos for the carrier, problem solved. Insurance kept the policy. Worth every penny."

Roof Cleaning FAQ

How much does roof cleaning cost in Naples?
Roof cleaning is priced per roof — there isn’t a flat rate that applies to every house. Cost depends on roof size, slope, accessibility, roof type (tile is more involved than shingle), how much algae and lichen is present, and whether gutters are included. Free on-site quote means we walk the property, give you a real number, and the number is what you pay. No surprises.

How long does the roof cleaning last?
A correctly-done soft wash clean lasts 2 to 4 years on most Naples roofs. Roofs in heavy shade or near the coast (Marco Island, parts of Pelican Bay) often need cleaning sooner — 2 years is common. Roofs in full sun in inland Naples can sometimes go 4+ years. The variable is shade and tree cover, not the cleaning method.

Will roof cleaning kill my plants and grass?
It can if not handled correctly — sodium hypochlorite is hard on plants. We rinse all surrounding plants and grass with fresh water before, during, and after the soft wash, and we use lower-concentration chemistry near landscaping. We’ve cleaned 5,000+ roofs without a plant casualty. If you have rare or sensitive landscaping, tell us during the quote and we’ll plan extra protection.

Do you clean the gutters too?
Gutter cleaning is a separate service we offer alongside roof cleaning. Most clients have us clean gutters at the same visit since the crew is already there — it costs less than booking the two services separately. Ask for it during the quote.

My HOA sent a letter about roof stains. Can you help with the documentation?
Yes. We can provide before-and-after photos, the date of service, and method documentation showing this was a soft wash (not pressure wash) clean — which most HOAs and insurance carriers explicitly require. Just tell us during scheduling.

Does roof cleaning fix insurance company concerns?
Often, yes. Insurance carriers have increasingly used aerial imagery to flag roofs with heavy algae staining and threatened policy non-renewal. A soft wash clean addresses the visible issue, and we can document the method and date for the carrier. Several Naples clients have successfully kept their policies after getting a clean done.
