Roof cleaning and moss removal in Guildford
Roof cleaning in Guildford is mostly moss removal. Moss grows on the north side of a tiled roof, holds water against the tiles through every frost, and slides off in lumps into the gutters each winter. We scrape and brush it off, clear the gutters of what has fallen, and treat the roof so it is slow to come back.
The clue is usually in the gutters. If they fill with moss every autumn, the roof is shedding it, and clearing the gutters alone is a yearly job that never ends. Taking the moss off the roof deals with the cause. It also lets you see the tiles again, which is how customers find out whether anything has slipped or cracked under the growth.
We do not pressure wash roofs. Pressure forces water under the tiles and strips the surface off them, which is what moss then grows into. Moss comes off by hand and brush, from a platform where the roof needs it and with a risk assessment before we start, and the roof is then soft washed and treated so the regrowth is slow. The debris is bagged and taken away.
A Checkatrade customer in Camberley, GU15, had us clear the moss from his elderly parents' roof in May 2026. The price was agreed, the work started a month later as planned, the team worked through the week and cleaned up as they went, and he scored it 10 out of 10. That is how a roof job should go, and it is the review we would send you first.

How we clean a roof
Four steps, with the price agreed before anyone goes near a tile.
Step 1: Look first, then quote
Patrick looks at the roof, the access and the gutters, and agrees a fixed price. That price is the price you pay, with nothing added on the day.
Step 2: Scrape and brush
Moss is scraped and brushed off the tiles by hand, from a powered platform where the roof needs it, with a risk assessment before we start.
Step 3: Clear the gutters
Everything that comes down ends up in the gutters, so they are cleared and the outlets checked before we leave.
Step 4: Treat and tidy
The roof is soft washed and treated to slow regrowth, the debris is bagged and taken away, and the drive is left as we found it.
Why Guildford homeowners book us for the roof
A roof job is a week of someone on a platform outside your house. The review from GU15 says how that week went.
Fixed price, never paid in advance. Patrick agrees the price before we start. The GU15 customer's price was agreed, the work started a month later as planned, and nothing changed.
Risk assessment and £5m cover. Every roof job has a risk assessment first, £5m public liability insurance behind it and a 100% safety record in 19 years.
Cleaned up as we go. Moss ends up everywhere if you let it. We bag it as we go and take it away, which is what the same reviewer mentioned.

“The process with Patrick was very professional, price was agreed and the work started a month later. On the day they turned up as stated and worked throughout the week. The roof looks good and they cleaned up as they worked.”

Common questions about roof cleaning and moss removal
Cost, how often, ladders and what counts as a clear.
How much does roof cleaning cost?
It depends on the size and pitch of the roof, how much moss there is and whether a platform is needed. Patrick looks first and gives you a fixed price. You pay once the job is done, never in advance.
Do you pressure wash roofs?
No. Pressure forces water under the tiles and strips the surface, which moss then grows into. Moss is scraped and brushed off by hand, then the roof is soft washed and treated.
How long does the moss stay off?
The treatment slows regrowth for years rather than months, but a north-facing roof under trees will always grow moss eventually. Clearing the gutters each autumn tells you how the roof is doing.
Will you tell me if a tile is broken?
Yes. Once the moss is off we can see the tiles, and if anything has slipped or cracked we tell you. We clean roofs; we do not repair them, so there is nothing to sell you.
