FAQs

Is Cromar Leadax truly a direct replacement for traditional lead?

Yes, Leadax is designed to offer the same workability, durability, and weather resistance as traditional lead, but without the toxic health and environmental concerns. It can be used in most applications where lead flashing would traditionally be specified.

How do I cut Cromar Leadax?

You can cut Cromar Leadax using standard heavy-duty shears or tin snips. Ensure clean, straight cuts for the best results when fitting.

Can Leadax be worked in cold weather?

Yes, one of the key benefits of Leadax is its continued malleability in various weather conditions, including cold temperatures, making it easier to work with than traditional lead.

What is the lifespan of Cromar Leadax compared to lead?

Leadax is manufactured for durability and long-term performance. While traditional lead has a very long track record, Leadax is engineered to provide comparable longevity and weather resistance in roofing applications.

How is Leadax fixed in place?

Leadax can be fixed using standard roofing nails or screws, often through pre-drilled holes or with the use of backing washers for added security, similar to how lead might be secured.

Is Leadax suitable for DIY use?

Yes, its lightweight nature and ease of handling make it suitable for both professional roofers and DIY enthusiasts undertaking roofing projects.

What is the material composition of Leadax?

Leadax is made from aluminium expanded metal coated with modified polyvinyl butyral. This combination provides its flexibility, strength, and weather resistance.

Does Leadax come in different widths?

Yes, Cromar Leadax is available in various widths to suit different roofing requirements, including the 400mm version featured here, as well as 150mm, 200mm, and 300mm options.

Troubleshooting

Material is difficult to shape or remains too rigid.

Ensure the material has been unrolled and allowed to relax for sufficient time. In very cold conditions, a gentle application of heat from a heat gun (on a low setting) might improve malleability, but avoid overheating.

Fixings are pulling through the material.

Use fixings with a wider head or backing washers to distribute the load. Ensure fixings are appropriate for the substrate and not overtightened.

Sealing edges are not adhering properly.

Ensure the surface is clean, dry, and free from dust or grease before applying sealant. Use a sealant specifically designed for roofing applications and compatible with the Leadax material.

Water ingress observed after installation.

Re-inspect the entire flashing installation. Check for gaps, improperly sealed edges, or inadequate overlap. Ensure the flashing extends sufficiently over the relevant roof elements and is correctly integrated with adjacent materials.

Setup, Compatibility & Care

Setup: The Cromar Leadax Lead Replacement Flashing is ready to use straight from the roll. Unroll the material carefully and allow it to relax for a short period, especially if stored rolled tightly. Shape the flashing by hand to fit the contours of the roof area. It can be cut to size using standard heavy-duty shears or tin snips. Secure the flashing using appropriate fixings such as nails or screws, ideally through pre-drilled holes or carefully hammered to avoid damaging the material. For sealing edges, use compatible roofing sealants or adhesives recommended for similar applications.

Compatibility: Leadax is designed to be compatible with most common roofing materials, including tiles, slates, bitumen, and felt. It can be used in conjunction with standard construction adhesives and sealants. Ensure that any materials it comes into direct contact with are suitable for long-term outdoor exposure.

Care: This product requires minimal care once installed. Its durable construction is designed for longevity. Periodically inspect the flashing as part of routine roof maintenance to ensure seals remain intact and there is no debris accumulation that could affect performance. Cleaning can be done with a damp cloth if necessary; avoid abrasive cleaners.
