The secret to roof cleaning for tile roofs is using the right method, not the most pressure. In Bennington, VT, we match the cleaner and pressure to the surface so it comes out clean without damage. For tile roofs, that means soft wash.
Method and pressure
Cleaning solution: A soft wash solution; moss and lichen may need a second application.
Caring for tile roofs
Clay and concrete tile roofs grow algae, moss and lichen, especially in shade. Tiles are brittle when walked on, so roof access is planned carefully and the roof is cleaned mostly with solution.
Avoid: High pressure, which erodes the surface of concrete tile, and stepping on the middle of tiles.
How often: Every 3-5 years.
