Moss holds water against your tiles, lifts them as it grows and washes into gutters until they block and overflow. Bristol's damp climate and leafy streets mean many roofs need clearing every few years.
We remove moss by hand, never with a pressure washer, which can crack tiles and force water underneath. Then we clear the gutters, check for damaged tiles and apply a biocide treatment that keeps the roof clean for longer.

Do you pressure wash roofs?
No. Pressure washing can crack tiles, strip their surface and drive water under them. We remove moss by hand and treat the roof instead.
How long does a roof clean last?
With a biocide treatment, most roofs stay clear for 3 to 5 years, depending on how shaded the roof is.
Can you clean my roof without scaffolding?
Usually, yes. We use roof ladders and access towers for most houses, which keeps the cost down.
