No single measure is a magic bullet, but the combination is genuinely effective. - Biocide top-up every 3–4 years — a fraction of the cost of a full clean - Zinc or copper ridge strips — trace metal ions inhibit spore germination - Trim overhanging branches back at least 1 metre from the roof - Annual gutter clean in late autumn - Consider tile-surface breather coating on old concrete tile only ## Why ridge strips work When rain falls on zinc or copper strips at the ridge, trace metal ions dissolve into the water and wash down the roof slope. Those ions create a hostile environment for moss spores. It's a passive, decades-long solution that costs a few hundred pounds fitted. ## The tree-trimming trade-off Homeowners are often reluctant to cut back mature trees for aesthetic reasons. That's a valid choice — but it means accepting a shorter cleaning cycle. The moss will return faster and you'll need attention every 3–4 years rather than every 5–6. ## Get a free Nottingham roof quote If you'd like a fixed-price quote for your Nottingham property, request a free roof inspection using the form on this page — we'll typically respond within one working day.

For most Nottingham properties, a full soft wash with moss removal and biocide falls between £400 and £950. Biocide-only treatments start around £250. Restoration work with re-colouring is a separate service and starts around £1,600. We provide fixed written pricing after a free inspection. What treatment schedule keeps moss under control in Nottinghamshire? A full clean every 3–5 years is standard. Roofs under tree cover, on north-facing slopes, or in the wetter west of the county often benefit from a biocide top-up at 24 months to hold results between full cleans. Should I choose soft wash or pressure washing? Soft wash. Pressure washing damages the tile surface, voids many manufacturer warranties, and forces water into places it doesn't belong. Soft wash is slower but preserves roof life and delivers longer-lasting cleanliness — the only method we use on domestic tile and slate. How long will results last on my Nottingham roof? Expect 3–5 years of visibly clean tiles and up to 5–7 years of heavy-moss control with a mid-cycle biocide top-up. Regular gutter clearance and trimming overhanging branches extend results further. ### Get a free roof cleaning quote Tell us about your property and we'll respond within one working day.
