Tile Roof & Gutter Soft Wash
Avellino Isles

Avellino Isles was the last neighborhood built in The Vineyards, going up in the mid-2000s behind its own gate inside the Vineyards’ main gate. It is a group of nearly 200 coach homes in two- and three-story Mediterranean buildings, with stucco walls, courtyard entries and barrel-style tile roofs. Lakes and the golf course surround the buildings, which is a big part of the appeal and also the main reason algae comes back. The Vineyards’ lakes and fairways keep the air around Avellino Isles damp, and the shaded sides of these two- and three-story buildings stay wet longest. Courtyard entries, garage aprons and planting beds below the eaves are pre-wet so no solution dries on stone, pavers or landscaping.

Listings from the last couple of years describe new tile roofs and gutters installed by the association. That gives the community a clean start, but it doesn’t last on its own. Moisture rising off the lakes, morning dew that sits on north-facing slopes, and the shade cast by one building onto the next give roof algae, Gloeocapsa magma, everything it needs. On new tile, the first grey shadows usually appear within a few years on the slopes that see the least sun.

Why new tile needs a gentle method. Concrete and clay tile has a surface finish that protects it from water and sun. Pressure washing wears that finish away, chips the edges of barrel tile, and blows fresh mortar out of ridge and hip caps. Once the surface is roughened, algae grips it harder and returns faster, so a pressure-washed roof ends up needing cleaning more often, not less. On a roof the association has just paid to replace, that is a poor trade.

What we do instead. A soft wash uses a diluted cleaning solution, based on sodium hypochlorite and mixed to the strength the roof actually needs, with a surfactant so it stays on the slope. The algae, mold and lichen die down to their anchoring cells instead of being torn off the surface. After it has had time to work, the roof is rinsed at low pressure. Any remaining shading fades with the next few rains as the dead growth washes off. Nothing is scrubbed and no tile is struck by a high-pressure stream.

The gutters. New aluminum gutters develop black vertical lines on their outer face within a year or two, often called tiger stripes. They form when dirty water flows over the edge and leaves an electrostatically bonded film on the paint. Roof washing alone won’t remove them. They need a separate gutter-face cleaner applied by hand, and they can be done on their own schedule, which is a cheap way to keep the buildings looking cared for between roof cleanings.

Who arranges the roof. In a coach-home condominium like Avellino Isles, the roofs and gutters are normally common elements, and the association decides when and how they are cleaned. We could not find a published policy naming the vendor for building cleaning, so if you are an owner, please check with the manager before booking roof work on your own building. If you are on the board, we can quote the community by building or as a whole, with a schedule that keeps residents informed.

Working in an occupied community. Coach homes share walls, entries and parking, so a roof cleaning affects several households at once. We post notices through the manager in advance, ask residents to close windows and move cars away from the building on the day, and protect courtyard plantings and entry doors from drift. With two gates to pass, we pre-register crews and vehicles so we don’t hold up the guardhouse.

Stucco and the lower walls. When a roof is cleaned, the runoff carries dead algae down over the stucco and the gutter downspouts. We rinse the walls as we go so no residue dries on them. Many associations choose to pair roof cleaning with a full building wash, because a clean roof above a grey wall looks unfinished, and doing both in one mobilization costs less per building.

How often. For new tile in a lake-and-golf setting, the simplest plan is a soft wash once the first algae shows and again whenever it returns, since ARMA says results are temporary. Buildings that sit in more shade, or face a lake to the north, may need attention on the shorter end. Gutter faces can be done every year or two. A roof inspection after each cleaning gives the board a record of the roof’s condition over time. We look at each slope from the ground and note the shaded, lake-facing sides where algae starts first, then confirm access and parking with the manager.

What drives the cost. The number of buildings, their height, roof shape and access set the price. Two-story buildings are simpler to stage than three-story ones, and buildings with courtyards and tight access take longer to protect. Pricing below is per-roof starting points; for the community as a whole we provide a written proposal, a certificate of insurance and a schedule the manager can share with owners.
