Moss looks harmless and does real damage. It soaks up water and holds it against the tile, and in winter that water freezes and splits the surface. The cushions grow into the joints between tiles, lift the edges and push water towards the battens. Then the first heavy rain washes lumps of moss into your gutters and blocks the downpipes.
We take the growth off properly and then look at what it was hiding. Over 25 years on roofs have taught us that moss covers cracked tiles and slipped ridges. You get a straight answer on whether cleaning is all the roof needs.
We work in a set order, so the roof ends up clean and treated, with the gutters running clear.
Thick moss is scraped and brushed off the tiles by hand, working down the slope towards a gutter we have protected. Pulling it off dry is safer for the tiles than blasting it away, and it keeps the worst of the debris out of the drains.
Algae, lichen and the stain left behind come off with a low-pressure wash. We keep the pressure down on purpose. A jet at full power strips the surface off concrete tiles and forces water up under the laps, which is how a cleaned roof ends up leaking.
A biocide wash goes onto the clean tiles to kill roots and spores that scraping leaves behind. Treated roofs stay clear for longer, and the moss that does return is thinner and easier to remove.
Everything that comes off the roof lands in the gutters and valleys, so we clear them as the last step. Tiles that cracked or slipped under the moss are replaced in the same visit. One reviewer had their roof cleaned and every broken and missing tile replaced in one job.
Each growth does different damage and needs slightly different handling. These are the three we find on local roofs.
| Growth | What it looks like | What it does |
|---|---|---|
| Moss | Green or brown cushions along tile edges and valleys | Holds water against the tile, splits the surface in frost and blocks gutters |
| Lichen | Grey, orange or yellow crusty patches | Grips the surface and eats into concrete and clay over time |
| Algae | Black or dark green streaks down the slope | Stains the tiles and keeps the surface damp |
Some firms arrive with a pressure washer and finish in an hour. The roof looks clean for a few weeks. The tiles have lost their top surface, which makes them more porous, and the moss returns faster and grips harder.
We scrape, brush and wash at low pressure, then treat. It takes longer and the roof lasts longer. If your tiles are already too far gone to clean without damage, we tell you before you pay.
Cleaning fixes the surface. It does not fix a cracked tile, a slipped ridge or a rotten batten. Once the roof is clean we check the whole slope and give you a priced list of any repairs, from roof tile replacement to ridge work and lead flashing.
If the tiles are worn out, cleaning is money wasted and we say so. At that point a new roof is the honest answer, and we quote it with the same free, no obligation visit. Our roof cleaning cost guide explains what the price depends on.
Moss is slippery, and a wet mossy slope is dangerous to stand on. We put up scaffold or use roof ladders and edge protection, and we risk assess every job before anyone steps onto the tiles. Brittle tiles and roof lights get crawl boards, and nobody works near an unprotected edge.
This protects your roof as well as our team. Tiles that are walked on carelessly crack, and a cracked tile is a leak waiting for the next storm. Careful access is part of why the roof is in better condition when we leave.
Roofs on north-facing slopes and under trees grow moss fastest, because they stay damp the longest. Concrete tiles on 1930s and post-war houses are porous, so growth grips them, and older clay tile roofs collect lichen. We work from our Dunstable office across Luton, St Albans, Hitchin, Bedford and the towns between.
Pair this with guttering work if your gutters have been overflowing, and ask us to check the whole roof edge while we are up there.
Call or send the form. We visit at a time that suits you and check the tiles, ridge and gutters, so you know what the growth is hiding before you spend a penny.
A detailed quote with labour and materials split out, a timetable, and a line for any tile replacement. We promise to beat any written quote.
After a risk assessment, we remove the moss by hand, wash the roof at low pressure, apply the treatment, clear the gutters and replace any broken tiles.
We take the debris away and leave the site clean. All work is backed with a 20 year written guarantee, and if you have a concern afterwards you call and we fix it.

cleaned all roof, replaced all broken and missing tiles and painted all the house really happy with all the work that has been don and i will certainly be using them in the near future.
Doyle Homes did a great job and cleared my guttering quickly, effectively and was well priced. Would recommend!
They repaired my roof and gutters, and the team was professional, efficient, and knowledgeable. They took the time to explain the repairs and answer all my questions. The work was completed in a timely manner, and they left my property clean and tidy. I would highly recommend them for anyone in need of roofing or gutter repairs. They are a top-notch company that truly cares about their customers.
Every job, from a single slipped tile to a full re-roof, comes with a 20 year guarantee in writing. You get it with your paperwork when the job is signed off, and if anything we did lets you down inside those 20 years, you ring the same number and we come back and put it right.

Yes. Moss holds water against the tiles, splits them in frost and blocks gutters. Left alone, it works into the joints and lifts tiles. We remove it and check the roof underneath.
We use a low-pressure wash after scraping and brushing the moss off by hand. A full-power jet strips the surface off concrete tiles and drives water under the laps, so we avoid it.
Moss returns on any roof that stays damp, but the biocide treatment slows regrowth and what comes back is thin and easy to remove. North-facing slopes and roofs under trees need a yearly check.
Yes. We replace cracked, slipped and missing tiles in the same visit and match the colour and profile. The cost goes on your written quote before we start.
Yes. Everything that comes off the roof lands in the gutters and valleys, so we clear and flush them as the final step.
