Roof Cleaning in Kent

What makes a Kent roof grow moss

Moss needs two things: shade and moisture. Kent is one of the drier parts of the country, so what decides whether a roof grows moss here is far more local than the weather — it is aspect, tree cover and the lie of the land. In the river valley around Maidstone the ground holds damp and the valley sides shade whole streets for much of the day. Out along the Swale and on the Isle of Sheppey, coastal exposure brings wind-blown debris and encourages algae and lichen rather than moss. And anywhere with mature tree cover, a north-facing roof stays wet long after the sun has dried everything else.

The result is that a roof here can look tired within a few years of being laid, and it is not only cosmetic. Moss pads hold water against the tile, lift edges as they thicken, and shed constantly into the gutters below — which is why a neglected roof so often turns into a blocked-gutter problem too.

That is why two houses on the same street can need completely different treatment, and why we look at a roof before quoting rather than pricing it from a postcode. Maidstone is where we are asked for roof cleaning most often — our roof cleaning in Maidstone page goes through the villages there one by one.
