Soft washing is the preferred approach. Low pressure rinsing and a biodegradable solution dissolve bio-film without scouring membranes, making it safe for metal, composite and single-ply systems.

Commercial roof cleaning removes moss, algae and grime that weaken coatings, trap moisture and increase energy loss. A clean surface protects assets, boosts building image and extends roof life.

Most roofs thrive on an eighteen to twenty-four month cycle. High-traffic or tree-covered sites may benefit from annual service to keep drainage clear and surfaces bright.

Key variables include roof size, degree of moss build-up, access complexity and any additional treatments like biocide or gutter clearance.

All surfactants are fully biodegradable and break down into harmless compounds after use, safeguarding staff, landscaping and local waterways.

Site surveys are usually arranged within a week, with cleaning dates agreed to align perfectly with your maintenance calendar.

Absolutely. Removing dark bio-film restores the roof’s reflective qualities, helping regulate internal temperature and easing the load on heating and cooling systems.

Yes. The low-pressure process avoids coating damage and halts galvanic corrosion by removing salt deposits and organic growth that hold moisture against the sheets.
