Yes, provided the method is suitable for the roof. We consider the material and condition of the tiles before recommending moss removal, softwashing or biocide treatment. Fragile roofs are not subjected to aggressive pressure washing.

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.

Biocide treatment targets residual organic growth and spores after heavier moss has been removed. It helps slow regrowth and continues working after application, allowing remaining staining to improve through natural weathering.

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.
