Types of Lead Rolls Flashing 

Standard Lead Flashing Rolls

Our standard lead flashing rolls from CALDER are available in various thicknesses, denoted by the lead codes from 3 to 8. Each code corresponds to a different thickness, which is suitable for various applications:

• Lead Code 3 and 4: These are thinner and more flexible, perfect for low-stress environments such as soffits and small roof repairs.
• Lead Code 5 to 8: These thicker options offer greater durability and are ideal for more demanding applications such as valley gutters and flashings around chimneys.

All our lead rolls come in lengths of 3m and 6m with various widths, providing flexibility based on your coverage needs.

Flex Lead Flashings Alternative

• Lead Codes 3 to 8: These rolls, available in both 3m and 6m lengths and in all widths, cater to diverse roofing requirements. The lead code number correlates with the thickness of the lead sheet, with higher codes indicating thicker sheets.
• Code 3 Rolls: Ideal for light applications such as soffits and small repair jobs.
• Code 4 Rolls: Suitable for general roofing and repair work.
• Code 5 to 8 Rolls: Increasingly robust, these are perfect for heavy-duty applications, including vertical cladding and flat roofing. 

Flex and Flex Plus Lead Flashing Alternatives

• Flex Lead Flashing Alternative: A versatile, non-lead based solution that is easier to handle and install than traditional lead flashing. Suitable for all sizes and shapes.
• Flex Plus Lead Flashing Alternative: An enhanced version of the Flex alternative, offering additional durability and adaptability.

Accessories for Lead Roll Flashing

To ensure a professional finish and secure installation, we also offer accessories:

• Lead Sealant: Essential for waterproofing and sealing joints, our lead sealant comes in boxes of 12 tubes, perfect for large or multiple projects.
• Lead Flashing Clips: These clips (sold in bags of 50) are crucial for securing lead flashing without the need for extensive tooling. 

Choosing the Right Lead Roof Flashings

Selecting the right type of lead flashing involves considering the application area, environmental factors, and the specific requirements of your roofing project. Here are a few guidelines:

• For general roof repair and weatherproofing, Codes 3 or 4 are typically sufficient.
• In areas with heavy water flow or where the flashing will bear weight, opt for the thicker Codes 6 to 8.
• If flexibility and weight are concerns, especially in complex roof shapes, consider our Flex or Flex Plus alternatives.

Our range of lead flashing products, provided exclusively by CALDER and ROOFTEC, ensures quality and reliability for all your roofing needs.

FAQs – Lead Flashing OR Flashing Rolls

1. What is lead flashing?

Lead flashing is a flexible sheet of metal used to seal joints and prevent water ingress at vulnerable areas of a roof, such as chimneys, valleys, and roof-to-wall junctions.

2. What is the purpose of lead flashing?

The primary purpose of lead flashing is to create a watertight barrier that directs rainwater away from roof joints and prevents leaks into the building structure.

3. Where is lead flashing used?

Lead flashing is commonly installed around:

• Chimneys
• Roof valleys
• Dormer windows
• Skylights and roof windows
• Roof-to-wall connections

These areas are most prone to water penetration.

4. Why is lead used for flashing?

Lead is widely used because it is highly durable, flexible, and resistant to corrosion. Its ability to be shaped easily makes it ideal for sealing complex roof details.

5. What are lead flashing codes?

Lead flashing codes refer to the thickness of the lead sheet. Different codes (such as Code 3, 4, 5, etc.) are used depending on the application, exposure, and durability requirements.

6. Does lead flashing require maintenance?

Lead flashing generally requires minimal maintenance, but it should be inspected periodically for cracks, movement, or poor installation to ensure continued performance.

7. How do I choose the right lead flashing?

When selecting lead flashing, consider:

• The correct lead code (thickness)
• Type of application (chimney, valley, junction)
• Exposure to weather conditions
• Compatibility with roofing materials

Choosing the right specification ensures long-term durability and effective waterproofing.
