Rated 5-star on Google 3-Year No Moss GuaranteeWhat's included
- The tiles, cleaned with a soft wash at low pressure, then treated with a biocide to slow moss regrowth.
- The gutters, cleared, because moss washed off a roof often ends up in them.
- The fascias and soffits, the boards along the edge of the roof.
- Any solar panels on the roof, cleaned at the same time.
- A tidy finish: if moss or debris from the roof marks your walls or paths, we rinse it off before we leave.
- You receive your work pack: the work carried out, before and after photos, and a written and signed No Moss Guarantee certificate.
Not included
- Roof repairs. If tiles are cracked, slipping or missing, get the roof checked by a roofer before it's cleaned.
- Roof coatings or paint. A biocide is not a coating.
- Driveways, patios and other outdoor jobs. You can add them to the same quote, and they're priced separately.
REVIEWS
How we do it
We clean every roof with a soft wash: a cleaning solution applied at low pressure, left to work on the moss, algae and lichen, then rinsed off gently. A biocide finishes the job by killing the spores and roots, so growth is slower to come back. We never jet-wash the tiles.
We don’t walk on fragile tiles; we use roof ladders, scaffold towers or a cherry picker instead. Scaffolding is needed on some tall or awkward roofs, and it can add several hundred pounds to the price.
A roof clean takes one to four days. Most semi-detached and terraced houses take a team of two a full day, and a large house with a roof of more than 300 square metres can take three to four days. You don’t need to be at home, as long as we can get through any gates.

When people book a roof clean
-
Before solar panels go on
Many of the roofs we clean are booked before solar panels are fitted. Once the panels are on, the roof under them is much harder to reach. Solar installers send customers to us for this.
-
Before selling a house
Many people book us before their house goes on the market. Buyers and their surveyor judge the roof from the outside.
-
Moss blocking the gutters
Moss on a roof ends up in the gutters and drainage and blocks them. We clear the gutters as part of every roof clean.
-
Moss spoiling how the house looks
A mossy roof makes a house look untidy from the street. A clean roof gives it back its kerb appeal.

Questions
How does the 20% off roof cleaning work?
Get your roof cleaning quote by 30 November 2026 and we'll take 20% off the price. The work itself can be done later.
Is moss removal included in a roof clean?
Yes. Every roof clean deals with the moss. The soft wash works on the moss, algae and lichen and is rinsed off, then a biocide slows it coming back. You don't need to book moss removal separately.
Do you need to visit to price it?
Usually not. We check the property on satellite view and confirm anything unclear with you over a call or text.
Will anyone walk on my roof?
No. We use roof ladders, scaffold towers or a cherry picker instead, because tiles and slates can crack underfoot.
How long does a roof clean last?
A roof cleaned and treated with a biocide usually stays clear for two to four years. Shaded, north-facing roofs and roofs under trees need cleaning sooner; open, sunny roofs last longer.
What if it rains on the day?
Light showers are fine. If heavy rain or strong wind would affect the result, we'll move your job to another day at no cost.
