How much does roof cleaning cost?

Typically from around £250 for a smaller roof with light staining up to £600 or more for a larger roof needing a full moss scrape and biocide treatment. We survey before quoting so the price reflects your actual roof.

Is the biocide treatment safe for pets, plants and drains?

We're trained in spill management and apply biocide carefully to avoid run-off into planting, ponds or drains. If you have particular concerns about a specific area of the garden, mention it when you book and we'll plan around it.

Does the method differ for slate roofs compared with tiled roofs?

Yes — slate is generally more brittle and needs a gentler touch, particularly on older roofs, while concrete tile has a rougher surface that holds moss more stubbornly and often needs a scrape before treatment. We adjust our approach to the roof in front of us.

Do you clear gutters as part of a roof clean?

We can, and it's often sensible to do both on the same visit since moss and grit dislodged during roof cleaning tends to end up in the gutters anyway. Ask us to quote both together when you book.

Are you insured for roof work?

Yes, we're fully insured for the roof cleaning work we carry out, including work from access equipment.

Do you guarantee the work?

We stand behind the quality of our cleaning and treatment. Regrowth timing varies by roof and location, so while we can't promise a moss-free roof forever, we'll always talk you through what to expect for your specific roof.

Durham County Council · DL12 · 29.5 miles south-west of our Washington base

Our roof cleaning is softwash-based: a biocide treatment applied at low pressure that kills moss, lichen and algae without disturbing the tiles or forcing water up under the laps the way high-pressure jetting does. Where moss has built up thick, we scrape it off by hand first, then treat what's left.

Roof cleaning in Barnard Castle typically runs from around £250 for a small softwash job up to £600 or more for a larger roof with heavy moss needing a full scrape and biocide treatment. Exact cost depends on roof size, pitch, access and how much moss has to come off before treatment.

We clean roofs across Barnard Castle and the wider County Durham area using softwash, steam and low-pressure methods — moss scraped off by hand where needed, biocide applied to kill what's left at the root, all done from ground level or access equipment rather than walking the tiles.

Roof Cleaning & Moss Removal near Barnard Castle

Coastal and near-coastal exposure

Roofs closer to the coast around Barnard Castle tend to pick up algae staining faster than inland properties, thanks to a combination of salt-laden air, higher humidity and more exposure to driving rain. It's less about moss specifically and more a general acceleration of anything that likes damp — algae, lichen, general black staining on north-facing slopes.

We treat these roofs the same way structurally, but tend to recommend a shorter interval between cleans for anything close to the coast, since regrowth is generally quicker there than a few miles further inland.

Pole-mounted camera

We use a pole-mounted camera to check gutter condition and confirm the roof's been cleaned thoroughly, without anyone needing to climb up for a look. It also gives you genuine before-and-after evidence of the work rather than a description of it.

Safety and access come before the clean itself

Every roof job starts with how we're going to reach the roof safely, not with the cleaning method. Wherever possible we work from ground level with extension poles, or from a cherry picker or podium for higher and steeper roofs, rather than walking the tiles — that's both a safety decision and the single best way to avoid cracking or slipping anything up there.

We're fully insured, biocide trained, and follow proper spill management practice so nothing runs off into guttering, drains or planting where it shouldn't. Where a roof has visible asbestos-containing material, our asbestos awareness training means we know to treat it differently and flag it rather than clean straight over it.

Heavy moss scrape and full treatment

1
Detailed survey
For roofs with significant moss buildup we assess coverage slope by slope, since heavier growth often needs more time than a standard clean.
2
Debris containment
Ground sheets and gutter guards go down first to stop scraped moss and grit washing into drains or planting.
3
Full hand scrape
Moss is scraped off by hand across every affected slope, working methodically from ridge to eave.
4
Biocide treatment
Once the roof is clear of loose growth, biocide is applied across the whole surface to kill root-level spores.
5
Gutter and downpipe clear
Everything dislodged during scraping is cleared from gutters and checked through to the downpipes.
6
Final inspection
We do a final check from access equipment for any missed patches or tiles that need flagging to a roofer.
