Lead is the most durable and versatile roofing material — properly installed, it lasts 100+ years. We fabricate and install lead flashings, valley linings, flat roof coverings, chimney back gutters, dormer cheeks and decorative details across West London. All work uses minimum code 4 lead to BS EN 12588.
Every lead flashing job in Twickenham is specified for the thermal conditions it will face. Code 4 lead (1.8mm) for standard flashings, code 5 (2.24mm) for valleys and flat areas. Maximum sheet lengths sized for expansion — a detail that cheaper contractors ignore until the lead cracks.
The most common lead failure we see in Twickenham is thermal fatigue cracking — London's heat island drives extreme expansion and contraction cycles that fatigue fold lines. Poor original specification (code 3 lead, oversized sheets) accelerates failure. We also see significant lead theft from accessible roofs in inner areas.
Lead remains the gold standard for flashings and valleys — nothing else matches its durability, workability and self-healing properties. Modern alternatives (GRP, proprietary flashings) have a place on budget projects but typically last 15-20 years versus 80-100+ years for lead.
Victorian and Edwardian terraces and villas throughout, with some Georgian properties near the riverside. 1930s semis in Whitton and Heathfield. Large Edwardian villas in St Margarets. Conservation areas around the town centre restrict material choices. For leadwork work in Twickenham, this housing profile means we commonly encounter River Crane and Thames proximity creates damp-related roof timber issues in lower-lying areas.

The streets of Twickenham — including Church Street Twickenham, Heath Road, London Road Twickenham — have roofing characteristics that reflect their construction era and the specific exposure conditions of Richmond upon Thames. The Thames winds through the borough from Hampton in the west to Kew and Barnes in the east, creating a microclimate with higher humidity than inland areas.

Properly specified and installed lead flashing lasts 80-100+ years. The key factors are correct code specification, adequate expansion allowance, and secure fixing. Poorly installed lead can fail within 10-15 years.
Lead fatigues through repeated thermal expansion and contraction. Cracking occurs at fold lines and where sheets are oversized (too long between fixings). The solution is to replace the failed section with correctly sized sheets.
Yes — lead on your roof poses no health risk to occupants. Lead is inert when installed and does not release harmful substances under normal conditions. The environmental concern with lead relates to manufacturing and disposal, not to its use on roofs.
Yes — we colour-match new lead to the patina of existing work using patination oil. On conservation properties in Twickenham, this ensures new lead does not stand out against aged sections.
Lead code refers to thickness — code 3 is 1.32mm, code 4 is 1.8mm, code 5 is 2.24mm. Higher codes are thicker and more durable but cost more. We specify code 4 minimum for all flashings and code 5 for valleys and flat areas.
We can install covert marking systems and use lead alternatives in high-theft-risk locations. For period properties where lead is essential, we advise on security measures including CCTV positioning and anti-climb provisions.
Hillingdon's roofing character is defined by the Metroland era. When the Metropolitan Railway reached Uxbridge in 1904, developers transformed farmland into the semi-detached suburban landscape that defines Ruislip, Eastcote, Ickenham and Northwood today. The houses built between 1920 and 1939 share common roofing characteristics — hipped roofs with plain concrete tiles, multiple valleys at hip junctions, and chimney stacks that are now approaching a century of weather exposure.
Hillingdon sits at Greater London's western edge where the urban heat island weakens and rural weather patterns take over. Ground frosts start earlier in autumn and persist longer in spring than in central boroughs — an extra 15-20 frost days per year that accelerates mortar deterioration and tile surface damage. The Colne Valley channels cold air across Uxbridge and the northern suburbs, creating frost pockets where ice can persist in shaded valleys and gutters for days.
Northwood and Eastcote properties command premium prices driven partly by their generous plots and period character. A complete re-roof on a large detached Northwood property can cost £15,000-25,000, but the alternative — visible deterioration reducing kerb appeal in an area where buyers expect immaculate presentation — costs more in the long run.
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.
Lead failures show up as damp where roofs meet walls.
When it is not the answer: Single crack at one fold: patch overlay is cost-effective.
Every lead junction checked from scaffold.
Lead code, sheet sizes, expansion provision documented.
Old lead removed, new dressed and fixed to spec.
Edges pointed with lead wedges and sealant.
| Job | Typical duration |
|---|---|
| Chimney reflashing | 1 day |
| Step/cover flash | Half day |
| Valley lining | 1-2 days |
| Bay window top | Half-1 day |
Lead dressed cold — complex shapes take longer.
Scaffold or tower — stable platform essential. Scaffold is specified for: all lead work - always itemised in your written quote, never a hidden extra, and we arrange it.
Victorian to inter-war mixed stock — access and scaffold requirements vary by street. Pavement scaffold and skip permits go through Richmond Council; allow a few working days on streets like Heath Road, Cross Deep where space is tight.
