Roof Cleaning & Moss Removal in Barnard Castle
North-facing roofs in Barnard Castle suffer worst for moss and algae — they never get sun to dry out. We pre-treat with a strong biocide, manually scrape thick moss, clear all gutters and downpipes of moss debris, then apply a long-lasting fungicidal coat to slow regrowth for years.
Why Choose Us for Roof Cleaning & Moss Removal in Barnard Castle
Soft-Wash, Never Pressure
We never blast roofs with high-pressure jets — it strips coatings and cracks slates. Soft-wash and hand removal is the only proper way.
Long-Lasting Biocide Included
After moss removal we apply a professional fungicidal biocide that kills spores and slows regrowth for years, not months.
Gutters Cleared as Standard
Roof cleaning without gutter clearance is pointless. We rod downpipes and clear outlets so the system flows freely.
Drone Survey Available
For restricted-access roofs we fly a drone for high-resolution inspection before quoting — no guesswork, no surprises.
