The problem
Moss, algae, lichen and loose debris can build up unevenly across a roof, particularly in shaded or slower-drying areas. Apart from changing the appearance, that growth can collect around tile edges, valleys and rainwater routes. The sensible first step is to establish the roof covering’s condition and whether cleaning is appropriate before choosing a method.
What's involved
- 01Reviewing the roof covering, visible defects, access and surrounding areas
- 02Agreeing a cleaning approach suited to the surface and level of growth
- 03Removing the agreed moss, surface growth and loose debris with care around adjoining property
- 04Checking the completed area and clearing debris created by the work

FAQ
Do you pressure-wash every roof?
No single method suits every roof. Tile material, condition, pitch and the type of growth all matter, so the cleaning approach is chosen after assessment rather than prescribed from a photograph alone.
Can every moss-covered roof be cleaned?
Not automatically. A roof with loose, cracked or particularly fragile areas may need repairs or a different approach first. Any visible concern is separated from the cleaning scope before work begins.
Will moss come back after cleaning?
Exterior surfaces continue to weather and biological growth can return over time. The pace varies with shade, moisture, surrounding trees and the roof surface. We can discuss sensible maintenance after seeing the property.
What should I send for a roof-cleaning quote?
The address, clear ground-level photos of each roof slope, notes about access and any known leak or damaged tile are useful. A site assessment may still be needed before the final scope is confirmed.
