Estate Roof Soft Washing
Port Royal

Salt settles on a waterfront roof every day it is windy, and salt film holds moisture. That damp surface suits the algae that streaks tile black, so waterfront roofs can show streaking sooner than a comparable roof farther inland.

Canal-front slopes that stay shaded and damp grow algae first. Estates here are large, with several wings, guest houses and long ridgelines, so a roof can look clean from Gordon Drive and streaked on the water side.

Tile cracks under careless feet and can be marked by too much pressure; metal finishes scratch and dull. A soft wash avoids both. We apply the solution at low pressure, with trained foot placement on tile and a gentler method on standing seam. See our metal roof cleaning page.

Matching replacement tile or specialty roofing on an estate this size can be slow and costly. Gentle cleaning on a sensible schedule is a much smaller expense, and the photos from each visit show how the roof is holding up.

A neighborhood built from marshland. Developer John Glen Sample spent about two decades turning roughly two square miles of marsh into buildable land by dredge and fill. His plan required every home to have water access, which is why so many roofs here face a canal or bay on at least one side.

Seventy years of homes. Lot sales began in 1950 and there were about 250 homes by 1973. Many early houses of 2,500 to 3,000 square feet have since been rebuilt far larger, so roofs here range from original-era structures to recent construction. We confirm the material and its age before setting the mix.

Concrete tile, by the maker’s rules. Eagle Roofing Products tells owners of its concrete tile to clean with water only, at 1,200 psi or less, because more pressure can shift the tile’s pH and leave discoloration. For heavy soiling it allows only a concrete-compatible cleaner in the weakest mix that works. Our soft wash runs far below that limit.

Clay and other specialty roofs. We have not gathered a maker’s cleaning guide for every material used on Port Royal estates, such as clay or slate-look products. On those we ask for the roofer’s or manufacturer’s instructions, test a small area first and keep pressure low.

Identifying the streaks. According to ARMA, the asphalt roofing trade association, Gloeocapsa magma is probably the most widespread algae behind roof discoloration, and it is most common in the Gulf States. Owens Corning calls it a cyanobacterium carried on the air that settles and grows on roofs.

Cleaning is not permanent. ARMA cautions that roof cleaning gives a temporary result and the dark streaks can come back. We don’t sell a fixed calendar. Each visit is photographed slope by slope, so the owner or manager can see when the water side begins to darken again.

Safety on the roof. Eagle warns that walking a wet tile roof is difficult and dangerous and recommends a licensed, insured contractor with tile experience who wears fall protection. Our crews follow that, and on tall rooflines we plan ladder positions with the manager in advance.

Docks, seawalls and the water. With docks and seawalls directly below many rooflines, we cover boat lifts and dock furniture near the drip line, keep runoff away from the canal, and rinse landscaping before and after. Owens Corning’s cleaning advice likewise ends with a full flush of the surrounding plants.

A record for the roofer. Eagle recommends routine professional inspections for cracked tile and drainage issues. We are not roofers, but we photograph cracked or slipped tile, worn ridge mortar and clogged valleys while we work and put them in the written record.

Respecting the neighborhood. Port Royal still follows tight deed restrictions and generous setbacks from its original plan. We keep trucks and equipment within the property where possible, arrive at agreed times and leave the grounds as we found them.

Guest houses and cabanas. Many estates have a guest house, pool cabana or boathouse with its own roof. Smaller structures with mortared tile ridges usually fall under the tile roof plus ridge cap row, from $349, and we quote each one separately so the owner can decide what to include in a single visit.

The main house. With several wings, long ridgelines and complex intersections, most main residences here are priced on the large estate or complex roof row, from $499. Simpler two-story roofs start at $399. We measure and photograph before confirming any number.

Near the Port Royal Club. The club opened in 1960 on a wide stretch of beach, and homes near it sit directly in the onshore breeze. Roofs facing the Gulf or Naples Bay often carry a heavier salt film, and we give those slopes a longer rinse once the treatment has done its work.

Seasonal and absent owners. Many homes are managed while the owners are away. Gate codes, alarm notes and pet or staff schedules go into our job file before the crew arrives, and the photos and service record go to whoever the owner names, often both the owner and the manager.

Walls and outdoor living. Rinse water runs down onto stucco, stone and outdoor kitchens below the eaves. We pre-wet those surfaces and rinse them after, and if you want the walls cleaned too, the roof and house wash combo starts at $599.
