No, lead flashing does not require adhesives or other fixing materials for installation. It is dressed to fit the roofing profile.

Patination oil is a protective coating applied after installation. It prevents the formation of white powder staining (patina) on the lead surface and ensures a consistent appearance, contributing to its longevity and aesthetic appeal.

A Calder 50-year warranty is provided, provided that the Lead Sheet Association (LSA) guidelines are followed during installation and care.

Yes, lead is renowned for its ability to be bossed or dressed, making it suitable for decorative flashings as well as functional applications.

Lead is quick and easy to install in most weather conditions once correct techniques are understood, and does not require the extra time and cost of applying adhesives.

This is a natural process, but can be prevented by applying patination oil immediately after installation and ensuring adequate ventilation. If staining occurs, it can often be cleaned and a fresh coat of patination oil applied.

Ensure the lead has been correctly dressed and is not being forced into position. Re-cut or adjust the dressing if necessary, following LSA guidelines. Avoid excessive stretching which can lead to thinning.

Check for incompatible materials in contact with the lead, or if corrosive substances have been used near the flashing. Ensure correct patination oil has been applied and maintained. Consult LSA guidelines for potential causes.
