Roof cleaning · North Bristol & south Gloucestershire

Moss off your roof, and kept off for good.

We scrape the moss, work safely from scaffolding, then treat the roof with biocide so it does not grow straight back. From £200 for a porch. A fixed price agreed before we start, never a number made up on the day.

A roof full of moss is doing more than looking untidy.

Moss holds water against your tiles, works into the gaps and lifts in frost, and washes down to block your gutters. Left alone it shortens the life of the roof. We get it off properly and then stop it coming back, so you are not paying to do the same job again in a couple of years.

How we clean a roof

1

Scaffold for safe access

We supply and set up scaffolding so the work is done safely and the whole roof can be reached properly. No shortcuts, no working off a ladder where it is not safe.

2

Scrape off the moss

The moss is scraped away by hand across the whole roof, including the gaps between tiles where it takes hold. The roof is left clear, not just the parts you can see from the road.

3

Biocide treatment

We treat the cleaned roof with biocide that kills off the spores left behind. That is what stops the moss growing straight back, so the clean actually lasts.

Before and after: a moss-covered roof scraped clean and treated to keep it that way.

Pay for the big job once, not every few years.

Scraping a roof is the expensive part, mostly because of the scaffolding and the labour. The biocide is what makes that worth it: once the roof is clean and treated, keeping it that way only needs re-treating, not scraping. So future visits skip the scaffold and the scrape and cost a fraction of the original price. You do the full job once, then a cheap treatment now and again keeps your roof clear for good.

Roof cleaning prices

Every roof is different, so the price depends on size, pitch and access. Here is what to expect, and you will always have a fixed figure agreed before we start.

Small roof / porch

From £200

A porch or small single roof, scraped and treated. The simplest job and the lowest price, often without the need for full scaffolding.

Typical 3-bed house

£1,200 front & back

The full job on a standard three-bed: scaffolding supplied, the whole roof scraped front and back, then biocide treated to stop it returning.

Future re-treatment

Much less than a first clean

No scaffolding, no scraping, just a fresh biocide treatment to keep your roof clear. We quote it once your roof has had its first full clean.

Roof cleaning questions, answered straight.

Why is the moss treated as well as scraped?

Scraping takes the moss off, but the spores left behind will regrow within a year or two. The biocide kills those spores, which is what makes the clean last. Scraping without treating is why a lot of roofs are green again so quickly.

Do I really need scaffolding?

For a full roof scrape, yes. It is the safe way to reach and work across the whole roof, and it protects both our team and your property. Smaller jobs like a porch can sometimes be done without it, which keeps the cost down.

How much does roof cleaning cost?

A porch or small roof starts from £200. A typical three-bed house, scraped front and back with scaffolding and biocide treatment, is around £1,200. Every roof is different, so you get a fixed price agreed before any work starts.

How long will the clean last?

Because we treat the roof with biocide after scraping, it stays clear far longer than a scrape alone. When it does eventually need topping up, that is a re-treatment only, at a fraction of the original cost.

Will it damage my tiles?

No. The moss is scraped by hand rather than blasted off with high pressure, which can crack or loosen tiles and force water underneath. Hand-scraping followed by treatment is the safe way to do it.

How do I pay?

Bank transfer (BACS) once the work is done. We agree the fixed price with you before we start, so there are no surprises at the end.
