An Expert Guide to Code 4 Lead: Technical Details, Uses, and Where to Buy

Lead roofing materials have been trusted for centuries for their durability and weather resistance. One of the most popular grades for roofing and construction is Code 4 lead, a versatile option that strikes a balance between flexibility and strength. In this article, we’ll explore the technical details of Code 4 lead, its various uses, and why The Lead Lads Shopis your best destination for purchasing flashing rolls. We’ll also introduce you to The Lead Lads, professional installers who specialize in lead roofing and flashing applications.

What is code 4 lead

Code 4 is one of the most widely used thicknesses of lead sheet in construction. The code number refers to the lead’s thickness and weight, with Code 4 sitting in the middle range, offering an ideal combination of durability and workability.

Thickness: 1.80 mm
Weight: 20.41 kg/m²

This slightly thicker lead provides extra durability and is more suitable for applications where additional strength is required, compared to thinner grades like Code 3.

Technical Details of Code 4 Lead

Composition: Code 4 lead is produced from refined lead, typically with a high recycled content, ensuring it meets the British Standard BS EN 12588. This standard ensures the sheet has a uniform thickness, providing consistent performance.
Increased Strength: Due to its greater thickness, Code 4 lead is stronger than lighter grades. It can withstand heavier loads and is more resistant to wear and tear from environmental conditions, making it ideal for areas with high exposure to wind, rain, or snow.
Durability: Lead is renowned for its ability to last for over a century with minimal maintenance. Code 4 lead is particularly durable in roofing applications, where it provides long-term resistance to the elements. It naturally forms a protective patina over time, shielding it from corrosion.
Flexibility: Despite its increased thickness, Code 4 lead is still flexible enough to be worked by hand, allowing roofers to mold it around complex details such as corners, chimneys, and ridges without compromising on strength.
Compatibility: Code 4 lead can be used in conjunction with other lead codes (such as Code 3 or Code 5) to achieve a cohesive roofing system, with each grade chosen according to the needs of specific parts of the roof.
Recyclability: Lead is a highly sustainable material, with most lead used in construction being recycled. Using Code 4 lead, therefore, contributes to environmentally friendly building practices.

Code 4 Rolled Lead sheet

Code 4 lead is often specified for areas of a roof that require extra durability, particularly in regions that experience more extreme weather. Here are some of the common applications for Code 4 lead:

The ultimate guide to leadwork

Roof Valleys: Roof valleys, where two roof slopes meet, are critical areas that need extra protection from water ingress. Code 4 lead is ideal for valley lining, providing robust waterproofing for these high-stress zones.
Chimney Flashing: Chimney flashing is another key application where this code of lead is frequently used. The thicker sheet provides excellent weatherproofing around chimneys, ensuring that rainwater is kept away from vulnerable joints between the chimney and roof.
Gutters and Box Gutters: Gutters made from lead, especially in heritage properties, often use Code 4 due to its strength and ability to handle the heavy flow of water. Box gutters, which are enclosed channels, also benefit from the robustness of this grade.
Parapet and Roof Abutments: Where roofs meet walls or parapets, lead flashing provides a long-lasting seal against water penetration. It is durable enough to handle movement between different materials without cracking or tearing.
Lead Soakers: Soakers, which are thin strips of lead placed between tiles and a wall to prevent water ingress, can also be made from Code 4 lead. The thickness of Code 4 provides additional protection in areas where water is likely to collect or flow.
Dormer Windows and Flat Roofs: Code 4 lead is a great choice for flashing around dormer windows or covering flat roofs. Its increased durability ensures long-lasting weather resistance, even in more exposed conditions.
