Roof Cleaning
The Colony Golf & Bay Club

The Colony faces Estero Bay, with bay access and a private island beach park reached by boat. Salt air off the bay settles on every roof and holds moisture against the surface, which suits algae.

Estate homes on the golf course and along the bay usually streak first on slopes facing the water or sitting in shade. Villa buildings may carry one roof over several owners, so the whole building looks best cleaned together.

Tower roofs are flat and gather salt, sand and debris around drains and parapets. They are association items, cleaned only with building approval and at low pressure.

Because the community borders the Estero Bay preserve, runoff matters. We control downspouts, use the mildest mix that does the job and rinse landscaping thoroughly on every visit.

A Tuscany Isle example. One recent Tuscany Isle listing was a 2002 concrete block and stucco home under tile, renovated in 2021 and 2022, with a screened lanai behind electric hurricane shutters and an open-air infinity-edge pool beside it. On a home like that we close the shutter housings off from spray and keep solution well away from the pool edge.

Concrete tile guidance. Eagle Roofing Products, a concrete tile maker, recommends cleaning with water only at 1,200 psi or less, noting that greater pressure can shift the tile’s pH and discolor it. Heavily soiled roofs may get a concrete-compatible cleaner in the weakest mix that works. We apply at far less pressure.

What the black streaks are. ARMA, the asphalt roofing trade group, says Gloeocapsa magma is probably the most common algae behind roof discoloration and is most widespread in the Gulf States. Owens Corning describes it as an airborne cyanobacterium, distinct from the green algae and moss found on shaded roofs.

Results don’t last forever. ARMA says cleaning gives only a temporary result and the streaks may return. Bay-front and shaded roofs can darken sooner than others. We photograph each slope so you can see when your roof is ready again, rather than following a fixed schedule.

Wet tile is risky. Eagle warns that a wet tile roof is difficult and dangerous to walk, and advises a licensed, insured contractor with tile experience who uses fall protection. We keep foot traffic down, step on supported tile only and work from the eaves when the pitch allows.

Newer towers with built-up roofs. A 2026 listing for Infinity I at The Colony, by The Ronto Group, describes block and concrete construction with a built-up flat roof. We don’t have a maker’s cleaning bulletin for built-up roofing on file, so on that system we follow the building’s roofer and any warranty terms, test a small area and keep pressure low.

Single-ply tower roofs. If an older tower has a TPO or PVC membrane, the maker’s guidance applies. GAF’s TAB-C-27 for EverGuard TPO calls for mild detergent, a soft brush and pressure no higher than 2,000 psi, and Sika’s bulletin 17-03 for its membranes prefers lower pressure with a wide nozzle held 16 to 24 inches off the sheet.

Rooftop terraces. Infinity I lists a rooftop sunset terrace among its amenities. Terrace floors sit over waterproofing, so we ask management what the surface is, keep pressure low and direct rinse water to the drains, away from door thresholds.

Brick-paved streets. The Colony’s streets are brick-paved. We park on driveways where possible, protect pavers below the drip line from solution and rinse them when we finish.

The golf course next door. The private Jerry Pate course plays to nearly 6,800 yards with paspalum fairways. For homes backing onto it, we keep ladders and runoff off the course and avoid working during early tee times when the club asks.

Notes for your roofer. Eagle advises regular professional checks for cracked tile and poor drainage. We are not roofers, but we photograph cracked or slipped tile, worn ridge mortar and clogged valleys and include them in your service record.

Who maintains the roof? On estate homes the owner books the work. On villas and towers it is often the association; the governing documents settle it, and the property manager can tell you which applies. We quote per building for a board, or per home when the roof is the owner’s responsibility.

Island beach park and the club. Residents share Bay Club dining, the resort-style pool, tennis, spa and fitness, and a 34-acre private island beach park reached by boat shuttle. Because so many owners are out at the club or on the water during the day, most roof visits happen without anyone home, and we email photos and the record when we finish.

Pricing. Large bay-front and golf estates usually fall under our complex roof row, from $499, and two-story homes start at $399. Villa buildings and tower roofs are quoted per building for the association.
