Tower Roof & Parapet Cleaning
Park Shore Condos

A Gulf-front tower roof takes salt, sand and wind every day. Salt holds moisture on the roof surface, sand drifts against parapets and into drains, and wherever water sits after a storm a dark film of algae and dirt can follow.

That matters to the building, not only to the roof. Grime on the roof and parapet caps washes down the facade with every rain, so a building that has just been washed can start streaking again sooner if the roof edge was skipped.

Many Park Shore towers are several decades old; Colony Gardens was among the first, and towers such as Le Parc (1990) and Club Brittany (1996) followed. Their roofs may have been replaced or recoated since, so we ask the manager for the roof system and any warranty terms before choosing the method.

A clean roof also makes problems visible. Blisters, open seams and cracked flashing are easier to spot on a clean surface, which helps the roofer or engineer the board already works with.

One of Collier’s first planned communities. Park Shore was developed by Raymond Lutgert and was among Florida’s first planned unit developments and the first in Collier County. A local brokerage counts more than 600 single-family homes, 25 high-rise condominiums and several mid-rises, which is why roof work here is booked tower by tower rather than for the neighborhood.

Towers from four decades. Building ages run from the early towers through Park Shore Tower (1985), Le Parc (1990) and Club Brittany (1996) to Aria in 2006, with Horizon House at 15 stories. A 1980s roof and a 2006 roof may carry very different membranes and repair histories, so no two quotes here use the same assumptions.

The roof is in the reserve study. Florida’s milestone inspection and structural integrity reserve study rules apply to condo buildings of three or more stories, and the reserve study covers the roof along with waterproofing, exterior painting, windows and exterior doors. Regular cleaning and a photo record give the board a better view of the roof between those formal reviews.

If the membrane is GAF TPO. GAF’s bulletin for its EverGuard TPO roofs allows a mild, non-abrasive household detergent, a washer at 2,000 psi or lower and a soft-bristled brush or broom, and warns against spraying at low curbs, base flashings or any point where water could get in. We work well under that ceiling and keep spray away from flashings and penetrations.

If the membrane is Sika. Sika’s 2023 bulletin for its Sarnafil and Sikaplan sheets says lower psi is better and that excess pressure can cut into or through the membrane. It calls for a wide fan held 16 to 24 inches up, spraying over seam overlaps rather than into them, no wire brushes, and says its bleach-based approach will not affect existing warranty coverage on those membranes.

Other roof systems. Some towers may have coatings, modified bitumen or a membrane from another maker. We have not gathered guidance for every product, so we ask the building’s roofer or manufacturer for its care instructions and follow them; if none exist we use the gentlest method that works and test a small area first.

Sand, salt and the drains. GAF notes that how often a roof needs cleaning depends on soiling, rainfall, dirt build-up and drainage, and that some roofs need none on a routine basis. On a first-row Gulf tower, sand and salt in the drains are part of that picture, so we clear drains and scuppers by hand before anything else.

Reflectivity and heat. Sika recommends cleaning its membranes every year to keep reflectivity at its best and notes heavy organic soiling may need extra attention. For a light-colored roof over a full floor of residences, a dull, dirty surface reflects less of the sun.

Crew safety on a wet roof. GAF says only trained professionals with fall protection should clean these roofs, because wet single-ply is slippery, and that no one should walk through unrinsed solution. We work in sections, rinse as we go and keep everyone back from the parapet.

Protecting the amenity decks. Towers such as Le Parc, Club Brittany and Aria have heated or lap pools, cabanas and sun decks below the roofline. Both GAF and Sika warn about runoff on plants and facades, so we route rinse water to roof drains and ask management to close the pool deck during the work.

How we write it up. Each tower gets its own written record with the date, roof areas cleaned, products used, drains cleared and photos of seams, flashings and anything that looked out of place. It is laid out to drop straight into the board packet, and more on our approach to low-slope roofs is on the flat roof cleaning page.

Near the beach park. Residents share the private Raymond L. Lutgert Beach Park, whose roughly 200 feet of sand sit on a 2.7-acre site. Equipment never goes onto the beach or the Commons walk; trucks stay where the building’s manager tells us to park.
