Frequently asked questions
How much will treating my moss cost in Nottingham?
A biocide-only treatment starts around £250. Full soft wash with physical moss removal and biocide typically runs £400–£950 for a standard semi, and £900–£1,600 for larger or heritage properties. Fixed quotes are provided in writing after a free inspection.
How often should moss be treated on a Nottinghamshire roof?
Full moss removal every 3–5 years is standard, with a biocide top-up every 24–36 months on shaded or tree-covered roofs. If your risk score above is 'High', treatment within the next 3 months is strongly recommended.
Can I just pressure wash the moss off?
Please don't. Pressure washing removes moss quickly but strips the factory coating from concrete tiles, opens micro-cracks in slate, and forces water past laps. Soft wash with biocide kills moss at the root, preserves the tile, and produces longer-lasting results.
How long will my roof stay moss-free after treatment?
3–5 years of visible cleanliness in typical Nottingham conditions, extending to 5–7 years of heavy-moss control with a mid-cycle biocide top-up. Annual gutter clearance and trimming overhanging branches make a measurable difference.
