Manual scraping. No tile damage.
Every tile inspected before we start. Scraping technique adjusted to the tile type. No shortcuts.
Why do Barnoldswick’s mill-era terraces and stone slate roofs need a specialist approach?
Barnoldswick’s housing stock is heavily weighted towards stone-built terraces from the cotton mill period. These properties have stone slate roofs, tight access between rows and often steep pitches — none of which suit pressure washing. The exposed hilltop position means wind-driven rain keeps tiles damp for longer, and the constant moisture cycle accelerates moss growth well beyond what you’d see in more sheltered towns. Manual scraping is the only method that works safely on stone slate without dislodging mortar or forcing water into the roof structure.
I inspect every roof before starting work, assess the tile type and condition, and use the right technique for your roof. Stone slates get treated with particular care — they’re irreplaceable on many older Barlick properties. You get before and after photos so you can see exactly what was done. And the biocide treatment means the results last — even in Barnoldswick’s challenging climate.
