Roof moss removal in Luton and across Bedfordshire

Roof moss removal in Luton and across Bedfordshire, done by hand from the roof rather than blasted with a pressure washer. Reliable Roofers Ltd scrapes the moss off, clears it from the gutters and the ground, treats the roof with a biocide to slow regrowth, and re-fixes the loose tiles and ridge pointing we always find underneath.

Moss grows on the north-facing and shaded slopes of most roofs in Bedfordshire, particularly on concrete tiles once their surface has weathered. It holds water against the tile, which freezes and breaks the surface, it blocks the gutters when it slides off, and it lifts tiles at the laps so wind-driven rain gets in. Left for years it becomes the reason a roof needs replacing early.

We do not pressure wash roofs. High-pressure water strips the surface off concrete tiles, drives water under the laps and into the loft, and takes years off the roof. We scrape moss by hand from the roof or the scaffold, brush the tiles, clear the gutters and downpipes, and apply a biocide that kills the spores and slows regrowth for years. Because we are roofers, we also fix what we find: slipped tiles, cracked ridge mortar and lifted flashings.

What is included

  • Moss and lichen scraped and brushed off by hand
  • All debris bagged from the roof, gutters, paths and drive
  • Gutters and downpipes cleared and flushed
  • Biocide treatment to slow regrowth
  • Loose or slipped tiles re-fixed while we are up there
  • Ridge and verge pointing checked
  • Roof condition report with photos
  • Optional annual return visit

Signs you need this

  • Thick green cushions on the north or shaded slope
  • Moss clumps in the gutters or on the ground after rain
  • Tiles lifting at the laps where moss has grown underneath
  • Damp patches in the loft on the mossy side
  • Gutters overflowing in heavy rain

How it works

Look and quote

We look at the roof and the gutters and give a fixed price.

Scrape and brush

Moss removed by hand from ladders, roof ladders or a scaffold depending on the roof.

Clear and treat

Gutters cleared, debris removed, biocide applied.

Fix and report

Loose tiles and pointing dealt with, photos and notes sent to you.

Anyone with a pressure washer can clean a roof and leave it leaking. We clean it as roofers, and we tell you what state it is actually in underneath.

Moss removal: your questions answered

Do you pressure wash roofs?

No. Pressure washing damages concrete tiles and forces water into the roof. We remove moss by hand and treat the roof with a biocide.

How long does the biocide last?

Regrowth is slowed for several years, depending on how shaded the roof is. Some customers have us back every two or three years for a light clean.

Will removing moss damage my tiles?

Not when it is done by hand. We scrape along the tile, not into it, and we re-fix anything that is loose.

Is moss actually harmful to a roof?

Yes, over time. It holds water, breaks tile surfaces in frost, blocks gutters and lifts tiles. A mossy roof fails earlier than a clean one.

Can you do this from the ground?

No, and be wary of anyone who says they can. Proper moss removal is done from the roof, which is why it should be done by a roofer.
