• Manufactured to Australian Standard AS 1804-1976
• Can be used as a dampcourse in brickwork to provide a moisture barrier
• Can be used as a flashing – particularly on roof applications around penetrations and gables on buildings
• The inert nature of lead makes it ideal for lining of chemical tanks
• The density of sheet lead makes it ideal for sound proofing as well as a barrier to low level radiation such as in x-ray rooms

Lead Sheet Applications

Sheets of lead for sale in Australia are widely used and highly popular for various applications, some of which include:

• Roofing/Flashing – Protects joints and penetrations from water damage, handles temperature fluctuations, prevents cracks, and outlasts other materials
• Radiation Shielding – Can be used to create lead lined walls and leaded glass, reducing healthcare workers’ exposure to harmful radiation
• Waterproofing – Creates an impermeable barrier against groundwater for underground storage facilities, parking garages, tunnels and other construction work
• Soundproofing – Absorbs and dampens sound waves that otherwise cause stress and permanent hearing loss for people nearby

Lead Sheet – Premium Roll & Sheet Lead for Flashing & Roofing

Lead sheet remains a trusted material in roofing and flashing solutions due to its durability, malleability and excellent weather resistance. Available at Singh Roofing Supplies in both roll and flat-sheet formats, our lead sheet is ideal for chimney flashings, valley linings, roof penetrations and bespoke waterproofing applications.

Material & Performance

• High-purity lead: Australian-grade, eco-friendly rolled lead in compliance with standards.

• Coated finish: Some suppliers offer acrylic primer-coated rolls (e.g. 300 mm × 3 m, 1.32 mm thick) to minimise water contact and reduce environmental leaching

• Thickness range (by “code” / nominal lbs per sq ft):
  • Code 3 – 1.32 mm (~15 kg/m²) suitable for small flashings

  • Code 4 – 1.80 mm (~20 kg/m²), Code 5 – 2.24 mm (~25 kg/m²)

  • Code 6 – 2.65 mm (~30 kg/m²), Code 7 – 3.15 mm (~36 kg/m²), Code 8 – 3.55 mm (~40 kg/m²)

• Sheet formats: standard sizes such as 600 mm × 600 mm sheets weighing ~15 kg each

Available Options

Benefits

• Easily formed & shaped: pliable enough for intricate chimney, valley or roof corner work

• Exceptional longevity: inherently waterproof, corrosion-resistant, and retains performance for decades.

• Compliant & certified: manufactured under recognised quality standards (ASTM B749, BBA certification)

• Eco-efficient: fully recyclable; primer-coated options reduce contaminant runoff

Applications

• Flashing around chimneys, skylights, vents, roofs, parapets

• Valley gutters and box gutters

• Roof-to-wall junctions and step flashings

• Waterproof lining for tanks, walls and specialist constructions

Installation Advice

1. Select correct code for thickness—Code 4 or 5 for standard flashings; thicker codes for parapets and valleys.

2. Ensure flat, clean surfaces before layout or roll bending.

3. Secure with copper or stainless-steel nails/screws and seal with neutral-curing silicone.

4. Apply patination oil to delay lead oxide appearance, or allow natural weathering.

5. Regular maintenance inspections to identify any splits or corrosion, especially near flashings.
