Why choose code 5 390mm 6m roofing lead?

The code 5 390mm 6m roofing lead roll is designed for medium–wide flashings, structural weathering details and premium roof coverings requiring the additional durability and rigidity of a heavy-gauge sheet. At 390mm wide and 6m long, it provides exceptional coverage while still offering flexible cutting options for installers who require multiple bays from a single roll.

Produced to BS EN 12588, the recognised material standard for rolled lead sheet, this product offers consistent metal thickness, tight dimensional tolerances and reliable behaviour when dressing, forming or welding. While BS EN 12588 governs material quality, installation and workmanship should always follow the Lead Sheet Training Academy (LSTA) manuals and the detailing principles set out in BS 6915.

Its strong combination of width and gauge makes code 5 390mm 6m roofing lead an excellent choice for chimney aprons, parapet wall flashings, dormer weatherings and wide abutments where long-term performance is essential.

Why choose Code 5 for demanding details?

Heavy-gauge lead provides superior durability in locations that experience greater thermal movement, weather exposure or physical loading. Code 5 390mm 6m roofing lead delivers:

• Excellent fatigue resistance for long-term service life.
• Strength for exposed, coastal or high-movement locations.
• Confidence for heritage and conservation-led roofing work.
• Greater stability when forming deeper flashings or structural joints.

When correctly installed in accordance with the LSTA manual and BS 6915, Code 5 offers a lifetime roof covering for many structural weathering applications.

Installation guidance

Install code 5 390mm 6m roofing lead using the workmanship principles set out by the Lead Sheet Training Academy / Lead Sheet Association and the dimensional rules within BS 6915. Remember that BS EN 12588 covers the material composition but not installation practice.

For authoritative summaries of installation standards, see:
The Lead Lads — BS 6915 Overview and
Neal Roofing — BS 6915 Leadwork.

Always cut this 6m roll into manageable bay lengths sized to the movement characteristics of Code 5. Apply patination oil after installation to reduce early oxidation and promote even, long-term weathering.

For terminating the sheet into masonry, use traditional mortar or
Lead Mate Sealant
depending on the detail and structural requirement.

Installation essentials
