Campus Roof Cleaning
Moorings Park

Moorings Park’s original campus at 120 Moorings Park Drive covers 83 acres inside the City of Naples. Independent-living homes are spread across an eight-story tower, a five-story mid-rise, garden apartments and courtyard residences, ranging from 882 square feet to several thousand.

Every home looks out on landscaped grounds, lakes or the fairways of the neighboring country club course. That view is what residents value, and it is also why the lower roofs among the trees and water stay damp.

On a campus this size, roofs age at different rates. Garden apartments and courtyard residences sit lower and closer to the trees, so their roofs stay shaded and damp and grow algae and lichen first. Leaf litter in valleys and gutters makes it worse.

The tower and mid-rise roofs sit up high, where salt and dust from the nearby coast settle and debris collects around drains and equipment. We expect flat or low-slope systems there and confirm each one with facilities. Their roof edges also determine whether facades streak after rain.

The campus also holds care buildings, including Orchid Terrace for assisted living, Oakstone, GardenView, The Chateau skilled nursing at 130 Moorings Park Drive and the Center for Healthy Living. Roof work near those buildings is timed with their staff as well as facilities.

Each building type needs a different method — soft wash at low pressure on pitched low-rise roofs, a mild solution and gentle rinse on flat roofs — and a different access plan. Treating it as one job leads to the wrong tool on the wrong roof.

On pitched concrete tile, we follow Eagle Roofing Products, a tile maker, which recommends water only at no more than 1,200 psi and warns that higher pressure can affect the tile’s pH and discolor it. Where tile is heavily soiled, Eagle permits a cleaner only in the most diluted, concrete-compatible form.

On any asphalt shingle roof, the Asphalt Roofing Manufacturers Association recommends bleach and water mixed to the shingle maker’s directions, left on 15 to 20 minutes and rinsed gently. Its guidance rules out a power washer as well as brushes or brooms on shingles.

For flat membranes on the tower and mid-rise, we follow the membrane maker’s guidance and the campus roofer’s instructions. Without those, we keep to low pressure and a mild solution and test a small area first.

The black streaking on pitched roofs is mostly Gloeocapsa magma, a cyanobacterium. ARMA says it is most widespread in the Gulf States, where warm, humid weather favors it, and Owens Corning notes it travels through the air and settles on roofs.

ARMA is direct that cleaning results are temporary and the discoloration can return. That is the reason this page talks about a plan by zone rather than a single visit.

The goal for facilities is predictability: a written plan showing which roofs are cleaned when, so the work can be budgeted and residents can be told in advance.

The campus is changing too. Perkins Eastman’s master plan adds a new lake surrounded by residences and amenities, a new town center, a renovated Clubhouse and Grille Room and the Center for Healthy Living with an aquatic center and spa. New roofs and old ones will need different schedules.

Pitched roofs over the garden apartments and courtyard residences are walked only where the footing is sound, with fall protection. Eagle calls a wet tile roof difficult and dangerous to walk, and we plan the dwell and rinse so the crew is not standing on wet tile longer than needed.

Covered parking structures have roofs of their own and are often overlooked. We include them in the zone plan and ask facilities to clear the spaces below on the day.

Walkways under roof edges are closed in short sections with cones and signs, with a marked detour. Paths reopen only after they are dry, because a wet path is a fall risk for residents.

Plantings and courtyard gardens below the eaves are soaked with fresh water before any solution goes on and rinsed again afterward. Owens Corning’s guidance after a bleach-based clean is to flush the roof and surrounding greenery thoroughly.

Drains, gutters and scuppers are cleared by hand on every roof, and any that run slow are noted for the roofer. Roof equipment and air intakes are identified first and kept out of the spray.

Moorings Park is a nonprofit, accredited continuing care community with more than 1,000 residents across three Naples campuses. The gated entrance has 24-hour security, so our crew is registered with security before each visit.

Building roofs start at $499 each as a minimum. Garden-apartment and courtyard roofs and roof-plus-facade work are quoted per zone, and the mid-rise and tower per building.

We are licensed and insured, send certificates of insurance to facilities, and leave a written record for each zone. Call 239-544-1165 to arrange a campus walk-through.
