Constant salt spray and humidity age coastal roofs fast. Here is what salt air does to shingles and metal, and how a soft-wash slows it down.
Homes on the water in Gulf Breeze, Navarre, and along Santa Rosa Sound take a beating from salt. Salt spray rides in on the Gulf breeze and settles on every surface, and the roof - the largest, most exposed surface on the house - gets the worst of it.
On asphalt shingles, salt draws and holds moisture, which feeds the black algae streaks (Gloeocapsa magma) you see on so many coastal homes. On metal roofs and flashing, salt accelerates corrosion at seams and fasteners. Either way, the damp, salty film shortens the life of the roof and stains it years before it should look old.
You cannot blast a roof clean - high pressure strips granules off shingles and drives water under panels. The right approach is a low-pressure soft-wash roof cleaning that kills the algae at the root and rinses the salt film without damaging the surface. Coastal homes benefit from it more often than inland ones.
Salt does not stop at the roof. Pairing a roof soft-wash with a house wash in Gulf Breeze keeps siding, soffits, and screens from staining too. Ask for an upfront quote and we will tell you what your home actually needs.
