What we do

A Proper Roof Clean, Done by Roofers

Plenty of firms will point a jet washer at your roof. We are roofers first, which changes how the job gets done:

  • Moss scraping by hand: clumps and growth lifted off the tiles course by course, without forcing water or debris underneath
  • Soft roof cleaning: gentle, low-pressure methods that clean the surface while protecting older tiles and slates
  • Gutter clearing included: gutters and downpipes emptied of moss and debris so the rainwater system actually works when we leave
  • A roofer's eye on every tile: cracked, slipped or delaminating tiles get flagged to you while we are up there, before they become leaks

Customers single this service out again and again: roof cleaning is one of the most mentioned jobs in our 202 five-star Google reviews. You get a free written quote first and our company workmanship guarantee behind the work.

Why it matters

What Moss Is Quietly Doing to Your Roof

A green roof looks harmless from the pavement. Up close, moss is holding water exactly where your roof least wants it.

Trapped Moisture

Moss works like a sponge, keeping the tile surface permanently wet. Tiles that never dry out weather far faster than they should.

Freeze-Thaw Cracking

In winter the water held by moss freezes and expands. Repeated cycles crack tiles and split their surfaces apart, one frost at a time.

Lifted Tile Edges

Thick clumps grow under the overlaps and prop the courses open, giving wind-driven rain a route into the roof space.

Blocked Gutters

Every downpour washes loose moss into the gutters. Blocked runs overflow down the walls, and blocked downpipes back the whole system up.

Damp Walls Below

Overflowing gutters soak the brickwork underneath. Green staining and penetrating damp on an outside wall often start with moss on the roof above.

Hidden Faults

A carpet of moss hides slipped and cracked tiles from view. Clearing it lets us, and you, see the true condition of the roof.

The Service Our Reviewers Keep Mentioning

Read through our Google profile and a pattern jumps out: alongside the big re-roofs, homeowners keep praising the roof cleaning. It is among the services most often mentioned by the 202 reviewers who have rated us 5.0, together with the politeness of the team, flat roof repairs and slate roof repairs.

That reputation is built on small things done properly: turning up when we said, working carefully on your tiles, clearing the gutters as part of the job and leaving the garden as we found it.

FAQs

Roof Cleaning Questions, Answered

No. Blasting a tiled or slate roof with high pressure can strip the surface of the tiles, force water under the courses and shorten the roof's life. We remove moss by hand-scraping and use gentle, low-pressure cleaning methods that lift the growth without harming the covering underneath.
Yes, over time. Moss holds moisture against the tile surface, and in winter that trapped water freezes and expands, which cracks and delaminates tiles. Thick clumps can also lift tiles at the edges and hold the courses open, letting wind-driven rain past. Clearing it is maintenance, not cosmetics.
Yes. The moss we scrape off has to go somewhere, and half of it is usually already sitting in your gutters before we arrive. As part of every roof clean we clear the gutters and downpipes of moss and debris and check the water runs away freely, so the job is finished properly rather than half done.
It varies with how shaded and sheltered the roof is: north-facing slopes and roofs under trees green up much faster than open, sunny ones. Rather than put you on an unnecessary schedule, we will tell you honestly at the survey how quickly yours is likely to regrow and when it is genuinely worth doing again.
Not the way we do it. Our team works carefully along the courses, scraping the growth off rather than dragging tiles about, and we flag any cracked or slipped tiles we find while we are up there. Roof cleaning is one of the services our customers mention most often in our 202 five-star Google reviews, which reflects how much care goes into it.
