What is 55kg Code 4 Roll of Milled Lead Flashing 450mm x 6m?
55kg Code 4 Roll of Milled Lead Flashing offers a versatile 450mm width and a standard 6m length, providing approximately 2.7m² of coverage per roll.
With an approximate weight of 55kg, this roll is a widely used and highly effective solution for a broad range of standard and detailed flashing applications on building exteriors where robust weather protection is essential.
Precision-manufactured to meet the stringent requirements of BS EN 12588, the "Code 4" designation refers to its specific nominal thickness of 1.80mm and a corresponding weight of 20.41 kg per square metre.
This lead flashing is produced through a milling process, which involves passing a cast lead slab through rollers to achieve a consistent thickness, fine grain structure, and a smooth surface finish.
Its fundamental purpose is to provide a durable, malleable, and completely waterproof seal at various junctions and intersections on building exteriors (such as roof abutments, around chimneys, in valleys, and over openings).
This prevents water ingress, protecting the building fabric from moisture damage and contributing to the structure's overall longevity. It requires the use of patination oil after installation to prevent unsightly white carbonate staining on the lead and adjacent materials.
Applications
- Standard Chimney Flashings: Ideal for forming front aprons (the lead flashing at the lower, front part of the chimney), side flashings (both stepped and straight), and back gutters (the lead channel at the upper, rear part of the chimney) for most standard to medium-sized chimney stacks.
- Pitched Roof Valley Linings: A very common width for creating durable and watertight valley gutters (the internal angle channel formed where two sloping roof surfaces intersect) on pitched roofs.
- Dormer Window Flashings: Perfectly suited for flashing the cheeks (the vertical side walls of a dormer window structure), aprons (the flashing section below the dormer window sill), and the flat or pitched roof sections of standard-sized dormer windows.
- General Abutment Flashings: Providing robust weatherproof seals where pitched or flat roofs meet vertical walls (e.g., at the side of an extension or conservatory).
- Flat Roof Upstands & Details: Effective for dressing up and over parapet walls (low protective walls at the edge of a roof) or against other abutting structures on flat roofs, and for flashing around outlets.
- Box Gutters: Suitable for forming or lining traditionally built box gutters of a moderate size.
- Cover Flashings over Upstands: Can be used as a substantial cover flashing where a lower roof meets a higher wall.
Benefits
- Exceptional Durability & Longevity: Offers an extremely long service life, often outlasting many other building components, due to lead's inherent resistance to corrosion, UV degradation, and atmospheric attack.
- Unrivalled Malleability: Easily dressed, shaped, and formed by hand or with simple tools to fit complex contours, abutments, and intricate roof details, ensuring a perfect, weatherproof seal.
- Proven Weatherproofing: Provides a completely impermeable barrier to water, making it highly effective in preventing leaks at critical building junctions across all types of roof coverings.
- BS EN 12588 Compliance: Manufactured to a recognised British and European standard, ensuring consistent quality, precise thickness tolerances, and correct lead composition for roofing and construction applications.
- Recyclable & Sustainable: Lead is 100% recyclable with a relatively low melting point, and lead flashing often has a high recycled content, making it an environmentally sound choice when responsibly sourced, installed, and eventually reclaimed.
- Aesthetic Appeal & Tradition: Weathers over time to an attractive, traditional grey patina that complements a wide range of building materials, both historic and contemporary.
- Noise Reduction: Due to its density, lead can also contribute to reducing noise transmission, such as rain drumming on a roof.
