Moss Removal • Biocide Treatment • Gutter Clearing

Roof Cleaning Guildford

After roof cleaning in Guildford? We clear moss, algae and debris from roofs across Guildford, Godalming, Cranleigh and Bramley - hand-scraped and treated properly, so the roof stays clean and the tiles stay in one piece.

Surrey's damp climate and tree cover make it ideal for moss, especially on shaded pitches. Allowed to build up, it traps water against the tiles, clogs gutters and cuts the life of the roof short. We clear it safely and treat it to keep it off - no tile-cracking pressure washing, one honest price.

Clean, treated, protected

Roof Cleaning in Guildford Done Safely

A mossy roof is more than just an eyesore. Once moss gets a grip it traps moisture against the tiles, works into the gaps and lifts them, and washes down into the gutters and valleys where it blocks things up. On the damp, shaded and tree-lined roofs common around Guildford, it takes hold faster than most people realise.

As local roofers in Guildford, we clean roofs in the way that protects them, not the way that's quickest. We hand-scrape the moss off and apply a biocide treatment that carries on killing regrowth for weeks afterwards - rather than a pressure washer, which can crack tiles, strip their surface and drive water underneath. That quick-blast approach often does more damage than the moss ever would.

While we are up there we will clear the debris from your gutters and give you a straight opinion on the roof's condition - if the moss has already done damage that needs repairing, we will tell you, and if the roof is basically sound, we will say so too.

Roof Cleaning & Moss Removal We Carry Out

We clean and treat every type of roof for homes across Guildford and the surrounding area, including:

  • Moss removal - carefully clearing moss off tiles and slates by hand without harming them.
  • Biocide treatment - applied after cleaning to kill remaining spores and hold back regrowth for years.
  • Algae and lichen treatment - removing the black and green staining that damp, shaded roofs attract.
  • Gutter and valley clearing - removing the moss and debris that washes down and causes blockages.
  • Roof health check - flagging any slipped tiles or moss damage while we are up on the roof.

Roof work is risky and not a job for a wobbly ladder - we have the access gear, insurance and experience to do it safely and leave the roof better protected, not damaged.

Frequently asked questions

Common Questions About Roof Cleaning in Guildford

A little moss is mainly a cosmetic thing. Heavy growth is different - it holds moisture against the tiles, can lift and separate them, blocks gutters and valleys, and in winter the trapped water freezes and speeds up the damage. Once it takes hold, it is worth dealing with.

Only with real care, and we usually advise against it. Pressure washing clears moss quickly but can crack or dislodge tiles, strip the protective surface off concrete tiles and force water underneath. On most roofs we hand-clear and treat instead.

Once the moss is cleared, we apply a biocide that keeps killing spores and regrowth for weeks, which keeps the roof clean far longer than clearing alone. It can look worse before it looks better - dead moss takes a while to weather off.

With hand-clearing and a proper biocide treatment, most roofs stay reasonably clean for two to three years. Spores are always in the air so nothing lasts forever, but after the first thorough clean a lighter maintenance treatment keeps it in check.

The mild, damp Surrey climate and no shortage of tree cover make ideal conditions for moss and algae, especially on north-facing and shaded pitches. Shaded, tree-lined properties around Guildford and the villages tend to need cleaning more often. We understand the local conditions and treat each roof accordingly.

We cover Guildford, Godalming, Cranleigh, Bramley, Woking and the surrounding Surrey area.
