What is included in the price
- Moss scraped and steamed off from our own scaffold tower and pole. Nobody walks on your tiles.
- The whole roof treated with a DDAC 50% biocide, which kills the spores so the moss does not come straight back.
- Gutters cleared of everything that came off the roof.
- Paths, drive and drains swept and hosed down before we leave.
- A 2-year no-moss guarantee in writing. If it grows back within two years, we come back and re-treat it free.
- No scaffolding hire. We bring our own tower and poles, so there is no hire cost added to the quote.
What changes the price
Roof size and pitch
A steep roof on a three-storey town house takes longer than a bungalow. This is the biggest factor.
How much moss there is
A roof that has never been cleaned takes a lot longer than one we treated a few years ago.
Access
Most roofs we reach from our own mobile tower. If a roof cannot be reached safely that way, we tell you before we quote, not on the day.
Roof type
Concrete tiles, slate, clay, flat and felt roofs each need a slightly different approach. We clean them all.
Other jobs on the same visit
Having the render or the drive done on the same visit costs less than separate visits.

Is roof cleaning worth it?
Moss holds water against the tiles. In a Pennine winter that water freezes and thaws, which is how tiles crack and spall. Heavy moss lifts tile edges so rain gets underneath, and when it falls it blocks the gutters and the overflow runs down the wall. Cleaning and treating a roof costs a fraction of the repairs that follow if it is left, and with the guarantee you are covered for two years.
Who this is for, and who it is not for
A good fit
Any roof with moss, lichen or algae on it: concrete, slate and clay tiles, and flat and felt roofs too. Houses across Lancashire and Greater Manchester, homeowners selling up who want the roof looking right for photos, landlords and commercial properties.
Not the right job for us
Roofs with broken, slipped or missing tiles that need a roofer first. We will tell you if we spot damage, but we do not do roof repairs.
Why you should never pay for a pressure wash on a roof
Some firms will pressure wash a roof for less. High pressure strips the surface off concrete tiles, drives water under the laps into the loft, and blasts the moss off without touching the roots, so it is back within a year. A cheap clean that damages the tiles costs more in the end. Read how we clean roofs and how our moss removal works.

Roughly £8 to £12 per square metre, including moss removal, biocide and the 2-year guarantee.
Does the price include scaffolding?
No scaffolding is needed on most jobs. We work from our own mobile tower and poles, so there is no hire cost in the price.

How long does a roof clean last?
Our roof cleans come with a 2-year no-moss guarantee in writing. Most customers go well beyond that before the roof needs doing again.
How long does the job take?
A normal semi takes a day. A large detached house or a farmhouse takes two.
Do you clean flat and felt roofs?
Yes. We clean any roof, including flat and felt roofs, as well as concrete, slate and clay tiles.
Is the biocide safe for pets and plants?
Yes, once it is dry. It is a DDAC 50% biocide applied at the right dilution for the roof.
Do you charge VAT?
No. Hydro Cleanse is not VAT registered, so the price you are quoted is the full price.
