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.

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.
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.
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.
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.
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.
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.
A porch or small single roof, scraped and treated. The simplest job and the lowest price, often without the need for full scaffolding.
The full job on a standard three-bed: scaffolding supplied, the whole roof scraped front and back, then biocide treated to stop it returning.
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.
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.
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.
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.
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.
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.
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.
Send your postcode and a photo of the roof if you can. You will have a fixed price back, with the scrape, scaffolding and biocide treatment all included.
