Moss growth on your roof is not just unsightly — it holds moisture against your tiles, accelerates freeze-thaw damage, lifts tile edges, blocks gutters, and reduces the lifespan of your roof covering Serving Northolt and all surrounding areas in Ealing.
Moss growth on your roof is not just unsightly — it holds moisture against your tiles, accelerates freeze-thaw damage, lifts tile edges, blocks gutters, and reduces the lifespan of your roof covering by years. We remove moss safely using soft wash techniques that clean without damaging tiles, clear all debris from gutters and valleys, and apply preventative biocide treatment.
Moss retains moisture against your tiles — in Northolt's climate, that moisture freezes in winter and expands, forcing tile edges upward and cracking the surface. Over 5-10 years, untreated moss can reduce tile lifespan by 30-40%.
We work from scaffold or ladder, never walking directly on moss-covered tiles. Stage one: biocide treatment to kill moss at the root. Stage two: soft brush removal of dead moss once treatment has worked (typically 2-4 weeks). Stage three: gutter and valley clearance. Stage four: preventative biocide to slow regrowth.
Moss regrowth is inevitable on north-facing pitches and shaded roofs in Northolt. Preventative biocide slows it significantly — from annual coverage to 3-5 year intervals. Zinc or copper ridge strips provide a longer-term solution by releasing trace metals that inhibit moss growth.

No — we strongly advise against pressure washing roof tiles. High-pressure water strips the protective surface from concrete tiles and can crack clay tiles. We use low-pressure soft wash and gentle brushing to remove moss safely.
The biocide treatment takes 2-4 weeks to fully kill moss. We then return to brush off dead moss and clear gutters. Attempting to remove moss before the treatment has worked risks dislodging tiles.
Moss will eventually regrow — the speed depends on orientation, shade and moisture levels. Preventative biocide after cleaning slows regrowth to 3-5 years on most Northolt roofs.
Yes — moss holds moisture against tiles, accelerating freeze-thaw damage, lifting tile edges and blocking drainage channels between tiles. Heavy moss growth can reduce tile lifespan by 30-40%.
We advise against DIY moss removal. Walking on a moss-covered roof is extremely dangerous — moss makes tiles slippery and hides cracked or loose tiles underneath. Professional removal from a safe working platform is the only responsible approach.
Yes — moss debris is the primary cause of gutter blockage. Every moss removal includes full gutter and valley clearance as standard.
Ealing's roofing heritage reflects its growth as a Victorian and Edwardian suburb. The earliest surviving roofs on properties around Haven Green and Ealing Broadway date from the 1880s — handmade clay peg tiles on steep pitches with decorative ridge tiles that are now almost impossible to source new. The 1930s building boom brought concrete interlocking tiles to the newer estates across Pitshanger, Northfields and South Ealing, and these roofs are now 85-90 years old and approaching the end of their design life.
Ealing's tree-lined streets create specific seasonal roofing challenges. Autumn brings heavy leaf fall from the mature London planes, limes and oaks that shade residential streets — blocked gutters, valley obstructions and moss-promoting debris accumulation are the predictable result. Winter frost affects the older clay tile stock more severely than modern concrete — water trapped in micro-cracks expands and spalls tile surfaces, a process that accelerates once the protective patina is lost.
A well-maintained roof in Ealing directly affects property value. With average house prices in W5 exceeding £700,000, a deteriorating roof can reduce sale value by £15,000-25,000 — far more than the cost of timely repair or replacement. Buyers and surveyors in Ealing are experienced enough to spot deferred roof maintenance, and mortgage lenders will flag roof condition on valuation reports.
Every job follows our standard quality process: free inspection and assessment, written quote with full scope of work, professional installation by our own team using specified materials, post-completion inspection with photographic record, and a written guarantee. This process applies to every job regardless of size — a £200 repair gets the same professional approach as a £15,000 re-roof.
We specify materials based on the specific conditions of your property — its age, construction type, exposure and the performance requirements of the job. We never use the cheapest available option as default — we use the right option for your situation and explain why. All materials are sourced from established manufacturers with proven track records.
All work carries our written workmanship guarantee. The guarantee period depends on the scope of work — from 2 years on minor repairs to 10 years on full installations. Guarantees are transferable if you sell the property. Materials carry the manufacturer's own guarantee in addition to our workmanship cover.
