Roof washing in Park Shore.

Park Shore roofs face the Gulf on one side and Venetian Bay on the other, and both put salt in the air above them. Salt on a roof is not just cosmetic: it is hygroscopic, so it holds moisture on the surface between rains, which is precisely the condition algae needs to establish on a slope that would otherwise dry out fast in the afternoon sun.

Our roof washing handles the growth and the film together, using a solution that kills the algae at the root and a low-pressure rinse that carries the salt off with it. Nothing is pressure-washed — on the tile common through the neighborhood that would crack and dislodge pieces, and on the metal roofs it would drive water under the panel seams.

On the waterfront lots the runoff is controlled and the beds are pre-wet and rinsed, so nothing concentrates on the landscaping or heads for the bay. Where the walls and the deck below have taken the same load, soft washing and pool deck cleaning are the matching jobs. More on the area in Park Shore.
