Why choose lead roll for roofing?
Lead roll has remained a trusted roofing material for centuries because it combines weather resistance, malleability and long life in a way few alternatives can match. In modern roofing and cladding, lead roll remains one of the best options for formed detailing, reliable waterproofing and heritage compatibility.
Unlike rigid sheet materials, rolled lead can be dressed, formed, welted and adapted around complex roof junctions. This makes lead roll especially valuable for chimneys, dormers, abutments, parapets, valleys, gutters and traditional roofing interfaces where a flexible but long-lasting material is required.
Typical uses for lead roll
- Roof valleys and pitched roof junctions
- Stepped flashings, cover flashings and chimney flashings
- Chimney aprons, back gutters and secret gutters
- Parapet weatherings, dormers and bay roofs
- Box gutters, gutter linings and outlet details
- Lead cladding panels, welts and heritage roofing work
Lead roll codes available online
We supply the full range of lead roll codes, all manufactured to BS EN 12588. Each code corresponds to a different thickness and weight per square metre, helping you choose the correct lead roll for the exposure, detail size and intended use.
- Code 3 Lead — lightweight lead roll for soakers, covered flashings and concealed details
- Code 4 Lead — general flashing lead roll for aprons, abutments and stepped flashings
- Code 5 Lead — heavier lead roll for bays, parapets, gutters and wider weatherings
- Code 6 Lead — heavy-duty lead roll for larger bays, parapets and specialist details

Manufactured to BS EN 12588
Quality matters when buying lead roll. Rolled lead sheet manufactured to BS EN 12588 helps ensure consistent material thickness, weight tolerance and performance across the sheet.
- Uniform thickness and weight tolerance
- Consistent metallurgical performance
- Reliable resistance to corrosion and fatigue
- Traceability and quality assurance for professional use
Lead roll installation and BS 6915 good practice
Good leadwork depends on correct detailing as much as material quality. BS 6915 guidance remains central to the design and installation of fully supported lead sheet roof and wall coverings.
Key principles include correct bay sizing, suitable substrates, thermal movement allowance, compatible fixings, proper jointing, ventilation where required and appropriate use of patination oil.
Why lead roll is still a sustainable choice
- 100% recyclable and reusable without loss of performance
- Long lifespan often measured in decades, and often over 100 years
- Low replacement frequency when correctly detailed and installed
- Circular material value within the roofing and salvage supply chain
Lead roll accessories and complete ordering
A good leadwork installation normally needs more than sheet lead alone. Alongside lead roll, consider ordering leadwork fixings, underlay, sealants, patination oil, clips and compatible nails so the full detail can be completed without delays on site.
Frequently asked questions — Lead Roll
What is lead roll used for?
Lead roll is used for roof flashings, valleys, aprons, bay roofs, gutters, parapets, cladding details and traditional weatherings. The correct code depends on the exposure, width, bay size and detail being formed.
What is the difference between lead roll codes?
Each lead code refers to a different thickness and weight per square metre. Lower codes are used for lighter flashings and soakers, while heavier codes are used for bays, gutters, parapets and more demanding roof details.
What standard should lead roll comply with?
Lead roll should be manufactured to BS EN 12588. Installation design and detailing should also follow recognised leadwork guidance such as BS 6915.
How do I choose the right lead roll?
The correct lead roll depends on the roof detail, exposure, width, bay size and function of the leadwork. Our lead chart is the best place to compare codes, widths and roll lengths.
