Leadwork Cranleigh

Leadwork Services Across Cranleigh

Cranleigh has tile-hung village buildings and 1960s extensions on Wealden clay. For leadwork work, this housing profile requires specialist knowledge that generalist roofers often lack.

Why Cranleigh Properties Need Specialist Leadwork

Our 20+ years of experience across Cranleigh 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.

Our Leadwork Process

Every leadwork job begins with a thorough survey. We assess your specific requirements, provide a written quote with material specifications, and schedule work at a time that suits you. All work comes with our 10-year guarantee.

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 Cranleigh

Cranleigh's clay soil creates persistent ground-level damp that wicks up masonry walls and attacks lead chase joints from behind — a problem that the Wey Valley's sandier geology does not produce. Our Cranleigh lead installations use deeper chase cuts and more robust sealant details to prevent moisture ingress from the wall side, not just the weather face.

Cranleigh Housing and Conditions

Cranleigh sits on the Low Weald clay plain south of Godalming — a fundamentally different geological setting from the valley. The heavy clay soil creates persistently damp conditions around buildings that the sandy Wey Valley does not experience. The village features tile-hung facades as a distinctive local architectural tradition, alongside standard tile and slate roofing.

Access in Cranleigh

Cranleigh's village centre has narrow streets around the High Street and Common where scaffold placement requires careful planning. The surrounding residential areas have good access with driveways and space for materials storage. Cranleigh is our most distant regular coverage area — 8 miles from Godalming — but we attend daily and maintain the same response times as local properties.

Common Problems in Cranleigh

The Low Weald clay creates ground-level damp that rises into fascias and soffits from below — a problem that the Wey Valley's sandier geology does not produce. Tile-hung facades are vulnerable to the same weathering as roof tiles but are harder to access for maintenance. The surrounding farmland and woodland generate more airborne debris than urban locations, blocking gutters and valleys more aggressively.

Local Tip for Cranleigh

Cranleigh properties with tile-hung facades should have these inspected alongside the roof — the tiles are the same material, facing the same weather, and failing on the same timeline. We assess tile hanging during every roof survey at no additional charge. Replacing individual hung tiles before they fall prevents the water ingress that damages the timber battens behind.
