Professional Roof Cleaning in Chinnor

One roof slope may receive less sunlight or remain shaded by trees and nearby buildings. These damp conditions allow moss and algae to establish more quickly than on exposed sections.

Biocide begins working after application, but the visual improvement is gradual. Remaining organic staining can continue breaking down over several weeks or months through natural weathering.

No. Pressure washing is not suitable for every roof covering or condition. We select the cleaning method after assessing the surface, level of growth and access requirements.

Softwashing is a low-pressure cleaning process used with a suitable professional treatment. It targets algae, moss spores, lichen and other organic growth without relying on the force associated with high-pressure washing.

The most noticeable difference usually comes from removing the heavier moss. Some lichen marks and organic staining may remain visible immediately after treatment but can gradually fade as the biocide continues working.

Roof cleaning can be completed throughout much of the year, but high winds, frost, ice or heavy rain may require the work to be rescheduled for safety.

There is no single schedule for every property. Roof orientation, surrounding trees, shade and local conditions all affect how quickly moss returns. We can provide maintenance guidance after assessing your roof.
