Leadwork Farncombe

Leadwork Services Across Farncombe

Farncombe has Victorian terraces and 1950s Binscombe estate. For leadwork work, this housing profile requires specialist knowledge that generalist roofers often lack.

Why Farncombe Properties Need Specialist Leadwork

Our 20+ years of experience across Farncombe means we arrive with the right techniques and materials for your specific property type. Leadwork work is not one-size-fits-all — the approach for a period cottage is fundamentally different from a modern estate home.

Lead Grades and Applications

Lead sheet is manufactured in codes from 3 to 8, with the code number indicating thickness (code 3 is 1.32mm, code 8 is 3.55mm). For roofing applications, we use: code 4 (1.80mm) for flashings and soakers where the lead is backed by masonry, code 5 (2.24mm) for valley linings and chimney back gutters where the lead is unsupported, and code 6 or 7 for flat roofs where the lead forms the primary waterproof layer. Using the correct code is essential — too light and the lead cracks from thermal fatigue, too heavy and it is unnecessarily expensive and difficult to dress. Lead Sheet Association technical bulletins specify the correct code for every application, and we follow these specifications precisely.

Thermal Movement — The Hidden Challenge

Lead expands approximately 3mm per metre between winter minimum and summer maximum temperatures. Over a typical 1.5-metre bay run, this means nearly 5mm of movement that must be accommodated without restraining the lead. Restraint causes fatigue cracking — the most common mode of lead failure. We achieve this by limiting individual sheet sizes to LSA maximum recommendations, providing proper roll joints or standing seams at regular intervals, and ensuring every piece of lead can move independently. This attention to thermal design is what makes our leadwork last 60+ years while amateur installations fail in 10-15.

Leadwork Specific to Farncombe

Farncombe's Victorian terraces have the highest density of chimney-related leadwork in our coverage area. Each terraced house has 1-2 chimney stacks with stepped flashings, an apron, and often a back gutter. After 120+ years, the original lead on many of these chimneys has fatigued beyond repair. We replace using Code 4 for flashings and Code 5 for gutters, matching the original detail but with modern thermal movement allowances that the Victorians did not design for.

Farncombe Housing and Conditions

Farncombe's housing stock splits between Victorian slate terraces along St John's Street and Station Lane, and 1950s concrete tile estates at Binscombe to the north. The Victorian properties feature multiple chimney stacks with original lead flashings, while the estate housing has simpler roof profiles but materials now past their design life.

Access in Farncombe

Most Farncombe properties have good rear access via gardens and alleyways. The terraced streets around the station require careful scaffold planning — narrow pavements and on-street parking can restrict lorry access. We arrange Waverley Borough Council pavement permits where needed and schedule deliveries for early morning before parking fills up.

Common Problems in Farncombe

The dominant issue on Farncombe's Victorian terraces is nail sickness on the original slate roofs — iron nails corroding after 120+ years, causing slates to slip progressively. On the Binscombe estate, concrete tile surface erosion and batten deterioration are the primary concerns after nearly 70 years of service.

Local Tip for Farncombe

Farncombe homeowners near the railway line should check for vibration-related tile displacement after heavy freight movements. We have seen tiles walk forward on their battens over decades of low-level vibration — a phenomenon unique to properties within 50 metres of the track.
