At St. Johns Wash and Seal, we provide professional roof washing and roof cleaning services for homeowners throughout St. Johns County.
Roof washing (often called roof cleaning) is one of the most effective ways to clean your home’s roof and protect it—when it’s done correctly. Using low-pressure soft washing, we safely remove the algae, mold, mildew, and moss that build up on shingle, tile, and metal roofs, without the damage that high pressure can cause.
If you’re looking for safe, careful roof cleaning—not high pressure or rushed work—you’re in the right place.
Roofs in St. Johns County face conditions that make regular cleaning especially important: high humidity, mold and algae growth, salt air in coastal areas, and constant sun exposure.
Using the wrong method—especially high pressure—can:
Crack tile and dislodge shingles
Strip the protective granules from asphalt shingles
Force water under the roofing and void manufacturer warranties
That’s why our roof washing is built around low-pressure soft washing—tailored to your roof’s material and condition, not applied the same way to every home.
Soft washing is a low-pressure cleaning method that uses specialized solutions to safely remove mold, mildew, algae, and other organic buildup. Roofs should never be pressure washed, and soft washing is the method roofing manufacturers favor.
Soft washing is ideal for:
Asphalt and architectural shingle roofs
Concrete and clay tile roofs
Metal roofing
Shaded, north-facing slopes where growth starts
Instead of blasting growth away, soft washing treats it at the source. This helps your roof stay cleaner longer—especially important in Florida’s warm, humid climate.
Most of what discolors a Florida roof is living organic growth, and soft washing clears it without harming the surface underneath.
We commonly remove:
Black streaks caused by roof algae
Mold and mildew in shaded, damp areas
Moss that holds moisture against the roof
Lichen rooted into the surface
Pollen, leaf litter, and general debris
Our team adjusts the solution and approach based on your roof type, ensuring a thorough clean without unnecessary wear or damage.
Before any roof washing project, we take the time to prepare properly.
That includes:
Evaluating your roof type and condition before we begin
Protecting landscaping, plants, and surrounding areas
Using low-pressure, material-appropriate methods
Working carefully around your home and property
Over time, algae, moss, and grime don’t just affect how your roof looks—they affect how your roofing materials age and perform.
Routine roof washing and roof cleaning can:
Restore curb appeal quickly
Remove growth that holds moisture against the roof
Help your roof reach its full expected lifespan
