Cleaning methodology must respect that reality: gentle chemistry, minimal physical contact, no pressure. ## The nail-fatigue problem Victorian and Edwardian slate roofs across Nottingham's inner terraces were typically fixed with cut iron nails. After 100+ years those nails have oxidised. A slate that looks perfectly sound can drop off if disturbed — a phenomenon called 'nail sickness'. ## Our approach For heritage slate we use soft wash chemistry, minimal physical contact and very gentle rinsing. Any loose slate identified during the process is noted for follow-up repair rather than repositioned in situ. ## When to re-nail rather than just clean If more than 5–10% of a slate roof is showing slipped or loose slates, cleaning alone isn't the right answer. Re-nailing key areas — sometimes strip-and-relay of entire slopes with copper nails — extends life by decades. ## Conservation area considerations Many Nottingham Victorian streets fall within conservation areas. That doesn't restrict cleaning but does affect any subsequent tile replacement — like-for-like natural Welsh slate is normally required rather than composite alternatives. ## 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.
