Roof Cleaning in Grays

Grays sits close to the Thames and experiences the humid estuary conditions that promote rapid biological growth on roof surfaces. The town's older terraced housing — particularly around the High Street and the established residential streets running south towards the river — often shows heavy moss colonisation on north-facing slopes, with lichen establishing on tiles that have not been cleaned for several years. Lichen is the most damaging of the biological growths: its root-like structures penetrate tile surfaces and hold moisture against them through freeze-thaw cycles, accelerating cracking and eventual failure.

We operate a low-pressure soft-wash system that applies a biocidal treatment to the roof surface, killing biological growth without the tile damage associated with high-pressure jetting. For older Grays properties where tiles may already be fragile, this is the only appropriate method. We cover RM16 and RM17 and can combine roof cleaning with gutter clearing in a single visit — important on Grays properties where moss debris routinely blocks downpipes and causes overflow staining on brickwork.
