Order Lead for Flashing by Code, Width and Length
The Lead Flashing Chart above provides a faster way to order lead for flashing online. Once you know the required lead code and developed width, compare the available roll sizes and go directly to the corresponding rolled lead sheet product.
The chart is designed around the way lead is actually specified on site: code, width and roll length. It can be used for chimney flashings, stepped abutments, aprons, cover flashings, soakers and other lead roofing details.

Lead Flashing Standards and Technical Guidance
Rolled lead sheet for building purposes is covered by BS EN 12588. The standard covers requirements including designation, chemical composition, surface condition and dimensional tolerances for rolled lead sheet used for applications including roofs, flashings and weatherings.
BS 6915 provides recommendations for the design and construction of fully supported rolled lead sheet roof and wall coverings, including the design and fixing of gutters and flashings. Product selection should therefore be considered alongside the design, support, jointing, fixing and movement requirements of the completed leadwork.
Frequently Asked Questions
What code lead should I use for flashing?
The appropriate lead code depends on the type of detail, sheet dimensions, exposure, support, fixing and movement requirements. Code 4 is commonly used for many conventional flashing details, but the complete specification should be considered before ordering.
What width of lead flashing do I need?
Calculate the complete developed width of the flashing, including the required upstand, chase, roof cover, folds, laps and returns. Do not base the order only on the visible width of the finished flashing.
Is Code 4 lead suitable for chimney flashings?
Code 4 rolled lead sheet is commonly used for many chimney, stepped, cover and abutment flashing details where the sheet dimensions, support and installation design are appropriate.
When is Code 5 lead used?
Code 5 may be selected for appropriately designed heavier weatherings or details requiring a thicker sheet. It should not be treated as an automatic upgrade from Code 4, as sheet dimensions and movement still need to be controlled.
Can I order lead flashing online?
Yes. Use the Lead Lads Lead Flashing Chart above to select rolled lead sheet by lead code, width and available roll length, then open the corresponding product and order online.
Buying Lead for Flashing: Codes, Widths and Roofing Applications
When buying lead for flashing, start with the detail being formed and select rolled lead sheet with an appropriate code, developed width and roll length. Chimney flashings, stepped abutments, aprons, soakers, valleys and wider weatherings place different demands on the material, so the specification should be considered before selecting a roll.
The Lead Lads Shop connects technical guidance directly with online ordering. Use the Lead Flashing Chart to find rolled lead sheet by code, width and length, then use the supporting guides and calculators where you need to check the specification or calculate material requirements.
Choosing the Correct Lead Code
Rolled lead sheet is identified by code, with each code corresponding to a nominal thickness and weight per square metre. Selection should take account of the type of detail, sheet dimensions, exposure, support, fixing and allowance for thermal movement.
Commonly used for concealed soakers and other appropriate lightweight details.
Widely used for many conventional chimney, stepped, cover and abutment flashings.
Used for appropriately designed heavier weatherings and details requiring a thicker sheet.
A heavier code is not automatically a better specification. Thicker lead must still be used within suitable sheet dimensions and with appropriate support, jointing, fixing and movement provision. Compare the Rolled Lead Sheet Codes Guide and Lead Weight Chart before ordering where the specification is uncertain.
Measure the Developed Width Before Ordering
The roll width should be selected from the complete developed width of the flashing rather than only the visible finished face. Depending on the detail, this can include the masonry chase, vertical upstand, cover over the roof surface, folds, welts, laps, returns and cutting allowances.
For larger projects or repeat purchasing, preparing a simple schedule of lead code, width, roll length and quantity for each detail can make ordering easier and help reduce unnecessary material waste.
Why Rolled Lead Sheet Is Used for Roof Flashings
Rolled lead sheet is widely used for roof flashings and traditional weatherings because it can be formed and dressed around complex roof and masonry junctions. When correctly specified, detailed and installed, leadwork can provide durable weather protection across both traditional and modern construction.
Its performance depends on the complete detail rather than material thickness alone. Appropriate sheet dimensions, support, joint formation, fixing and allowance for expansion and contraction are fundamental parts of good leadwork.
Common Lead Flashing Applications
- Chimneys: front aprons, side flashings, soakers and back gutters
- Roof abutments: stepped flashings and cover flashings
- Aprons and weatherings: beneath windows, copings and projecting details
- Soakers: concealed beneath slates and tiles at wall junctions
- Valleys and gutters: where the code, support and bay dimensions are appropriately designed
- Parapets and dormers: formed junctions and weatherings
- Heritage work: traditional roofing, repair and conservation details
Complete the Leadwork Order
Rolled lead sheet is often only one part of the material package. Depending on the detail, you may also require copper nails, clips, wedges, underlay, separating layers, patination oil and specialist leadworking tools.
Technical Guidance Before You Buy
Product selection should be considered alongside the design and installation of the leadwork. Sheet and bay dimensions, thermal movement, fixing, joint formation, substrate preparation and compatibility with surrounding materials can all influence the completed detail.
Rolled lead sheet for building purposes is manufactured to BS EN 12588. For practical information on codes, dimensions, weights and installation principles, use the technical resources throughout The Lead Lads Shop.
Lead Flashing for Trade, Construction and Repair Projects
The ordering system is intended for professional roofers and leadworkers as well as builders, contractors, surveyors and property owners who need a clearer way to identify and purchase rolled lead sheet. The same chart can be used for an individual chimney repair or as the starting point for a larger schedule of leadwork materials.
If you already know the specification, return directly to the Lead Flashing Chart. If you are still establishing the code or quantity, use the technical guides and calculators before selecting the product.
Larger and Mixed Lead Orders
For straightforward orders, use the chart to purchase individual rolls directly online. Where a project requires several lead codes, widths, roll lengths or larger quantities, prepare the required material schedule and use the Lead Flashing Quote page for a project-specific enquiry.
