Leadwork in South London

Traditional Lead Techniques We Use

We use bossing (shaping lead by hand with wooden tools) for complex junctions and welding for sheet joins. Lead is cut, marked, dressed to shape, and fixed with copper clips — never nailed through the sheet. Every joint incorporates expansion allowance because lead moves significantly with temperature change. Step flashings are chased into mortar joints and sealed with lead wedges and mastic. This is specialist work that requires training and experience — incorrectly installed lead fails within years. Correctly installed, it lasts 60–100+ years.

Lead Codes Explained — Why Specification Matters

Lead sheet is specified by code number — a weight measurement. Code 3 (1.32mm) is the minimum for small flashings and soakers. Code 4 (1.80mm) is standard for valleys, aprons and larger flashings. Code 5 (2.24mm) is used for flat areas, box gutters and high-exposure locations. We see cheap repairs across South London where code 3 has been used in valleys — it fatigues and cracks within 5–10 years because it is too thin for the thermal cycling and water flow. We specify the correct code for every application, every time. The cost difference is small. The lifespan difference is decades.

Lead Alternatives — When They Make Sense

Lead-free alternatives like Ubiflex, EasyFlash and zinc composite strips are available and work well for some applications — particularly where lead theft is a concern or where budget is limited. However, they do not match lead's lifespan, workability at complex junctions, or aesthetic on period properties. For conservation areas across South London, traditional lead is usually mandatory. We advise honestly on which applications suit alternatives and which genuinely need lead.

South London's Housing Stock and Leadwork

South London's housing diversity means leadwork is never one-size-fits-all. Victorian terraces in Brixton and Peckham have different roof types and failure patterns than 1930s semis in Bromley and Croydon. Georgian townhouses in Camberwell and Blackheath require heritage-grade materials that conservation areas mandate. Post-war estates in Thamesmead and New Addington present entirely different challenges again. We have worked on every property type across every South London borough and specify materials and methods appropriate to each.

This depth of local knowledge means we diagnose faster, specify correctly first time, and deliver repairs that last. A national company sending a subcontractor who has never worked in South London cannot match that. We live here, we work here, and we understand what these roofs need.

South London Borough-by-Borough Coverage

We cover every borough south of the river. In Lambeth — Brixton, Clapham, Streatham — the dense Victorian terraces with their Welsh slate roofs and butterfly roof box gutters present specific challenges that require specialist knowledge. In Southwark — Peckham, Camberwell, Dulwich — the mix ranges from workers' cottages to grand Georgian townhouses on Camberwell Grove, with conservation area restrictions in Dulwich mandating natural materials. In Lewisham — Brockley, Catford, Forest Hill — Victorian and Edwardian stock dominates, with the Ravensbourne valley creating humidity conditions that accelerate slate nail sickness. In Greenwich — Blackheath, Woolwich, Eltham — Georgian heritage properties sit alongside the largest concentration of 1930s semis in South London. In Bromley — Beckenham, Petts Wood, Chislehurst — substantial 1930s and Edwardian houses with complex roof forms and heavy tree coverage require regular maintenance. In Croydon — Thornton Heath, Purley, Selsdon — the sprawling 1930s suburban stock faces particular challenges with hip tile mortar failure across thousands of hipped roofs. In Wandsworth — Battersea, Putney, Tooting — Thames-side humidity accelerates metal corrosion on the riverside properties while the Edwardian stock further south has its own distinctive repair demands.
