Why regular roof cleaning & moss removal matters in Harrow
Harrow's hillside streets and mature gardens mean moss thrives on north-facing roof slopes and gutters fill quickly with needle debris.
We work on large interwar semis and detached homes with steep pitches across Harrow. Our team checks the access and the condition of the surfaces before starting, so you know what the clean involves and what it will cost.
Our roof cleaning & moss removal method
Moss is scraped back by hand or with controlled low-pressure tools — never a high-pressure lance, which strips the protective granules from tiles.
The roof is softwashed to lift lichen staining and algae, with gutters cleared of the fallen debris afterwards.
A biocide treatment is applied to slow regrowth, and we tell you honestly when a roof simply needs a repair instead.
Harrow questions we get asked
Is pressure washing safe for roofs in Harrow?
We don't pressure wash roofs. On large interwar semis and detached homes with steep pitches around Harrow that would shorten tile life considerably, so we scrape and softwash instead.
How long before the moss comes back?
With the biocide treatment applied, most roofs stay visibly clear for three to five years depending on tree cover and how much shade the slope gets.
