Roofing Lead Guide

What Is Roofing Lead?

Roofing lead is rolled lead sheet used for weatherproofing roofs, chimneys, valleys, gutters, abutments, dormers, bay windows and specialist leadwork details.

It remains one of the most durable and versatile roofing materials available. Correctly specified and installed, lead can provide long service life, excellent weather resistance and a finish suitable for both modern and heritage buildings.

The key to ordering the right roofing lead is understanding lead codes. Each code relates to the thickness and weight of the sheet. Code 3, Code 4, Code 5, Code 6, Code 7 and Code 8 lead all have different common uses, from soakers and flashings through to gutters, valleys, flat areas and conservation work.

Code 3 Lead

Lightweight roofing lead commonly used for soakers and concealed details.

Code 6 Lead

Heavier lead sheet suitable for valleys, gutters, dormers and more exposed details.

Code 4 Lead

A widely used roofing lead for flashings, cover flashings, abutments and general roof detailing.

Code 7 Lead

Used for heavier-duty gutters, channels, valleys, cladding and specialist leadwork.

Code 5 Lead

A versatile option for chimney flashings, step flashings, valleys and exposed roof details.

Code 8 Lead

Heavy roofing lead for high-exposure areas, demanding specifications and specialist work.

Roofing Lead Installation Essentials

Buying the correct lead is only part of the job. Rolled lead sheet must also be installed with the right substrate, fixings, laps, underlay, falls and allowance for thermal movement.

Use suitable lead underlay to separate the lead from the substrate and help reduce abrasion and condensation risk.
Use correct fixings, including copper nails and stainless steel or copper clips where appropriate.
Allow for thermal movement by keeping bay sizes, laps and joints within recognised guidance.
Use patination oil to help reduce early staining from lead carbonate run-off.
