Code 3 Lead Flashing – 3m & 6m Rolls
Code 3 lead flashing is commonly used for concealed soakers, covered flashings and other appropriate lightweight leadwork where the sheet remains protected within the roof detail. Shop Code 3 rolled lead sheet below in a range of widths and 3m and 6m roll lengths.
With a nominal thickness of approximately 1.32mm and nominal mass of approximately 15.0kg/m², Code 3 provides a relatively light and workable rolled lead sheet for appropriately designed concealed details. Typical applications include individual soakers beneath slates or tiles and selected covered flashing arrangements.
Code 3 should not be treated as the general specification for exposed lead weatherings. For conventional chimney flashings, stepped abutments, aprons and other appropriate exposed details, compare Code 4 lead. Where the design, application or sheet dimensions require a thicker rolled lead sheet, compare Code 5 lead.

Where Is Code 3 Lead Typically Used?
Code 3 lead is commonly used for individual soakers, covered flashings and other appropriate concealed leadwork where relatively small pieces of rolled lead sheet are incorporated beneath slates, tiles or a separate exposed weathering. Its nominal thickness of approximately 1.32mm and nominal mass of approximately 15.0kg/m² make it a comparatively light and workable lead code for suitably designed details.
Code 3 should not be selected simply because a detail is concealed. The appropriate lead code also depends on sheet dimensions, support, fixing, exposure and allowance for thermal movement. For conventional exposed flashings and weatherings, compare Code 4 lead. To compare available Code 3 widths and roll lengths, use the Lead Flashing Chart.
Typical Code 3 Lead Applications
- Individual lead soakers beneath slate roof coverings
- Soakers incorporated beneath appropriate tile roof details
- Concealed leadwork beneath stepped and cover flashings
- Selected chimney-side details beneath the exposed weathering
- Traditional roof repairs requiring individual lead soakers
- Other appropriately designed small-format concealed lead details
Code 3 or Code 4?
- Code 3 is commonly associated with individual concealed soakers and other appropriate small-format details
- Code 4 is commonly specified for conventional exposed flashings and weatherings
- The correct code depends on the complete detail rather than thickness alone
- Sheet dimensions, support, fixing and thermal movement must also be considered
- Use the Lead Flashing Chart to compare the available products before ordering
Lead Soakers
Code 3 is commonly used to form individual lead soakers incorporated beneath slates and appropriate tile details at roof-to-wall junctions. Each soaker works with the surrounding roof covering and flashing arrangement to help weather the junction.
Covered Lead Details
Code 3 may also be used for appropriately designed covered leadwork where the sheet is protected by the surrounding construction or a separate weathering. The required code should still be checked against the dimensions and design of the detail.
Traditional Roof Detailing
Traditional pitched-roof junctions can combine different lead codes within one detail. Individual Code 3 soakers may, for example, sit beneath a separately formed exposed flashing in Code 4 lead where appropriate.
