Lead is one of the most environmentally-friendly materials used in the construction industry. Lead sheet is produced from 100% recycled lead, also recycled lead has a low carbon footprint and a low energy consuming melting temperature. The initial installation cost of lead is comparable to man-made flashings when the additional expense of adhesives and sealants are taken into account. Lead is quick and easy to install in most weather conditions and requires no adhesive or other fixing materials. Alternatives are very limited in the types of applications that they can be used for, and would not be suitable for more decorative flashings for which lead is renowned. When bossed or dressed correctly, lead has few laps or joints, resulting in a high degree of weather tightness. Lead lasts up to 100 years, and when used for flashings will last three times longer than most man-made products. There is little post-installation inspection or maintenance required. All lead sheet should be coated with patination oil after installation. Calder 50-year Warranty (provided LSA guidelines are followed).

FAQs
What is Code 5 lead flashing?
Code 5 refers to the thickness of the lead sheet (approximately 2.0mm or 2.5mm). It is a common code for roofing applications, offering a good balance of workability, durability, and cost-effectiveness.
How long does lead flashing typically last?
Calder Industrial Code 5 Lead Flashing can last up to 100 years, providing a lifespan three times longer than most man-made alternatives. This longevity is a key benefit for long-term roof protection.

Yes, lead is one of the most environmentally friendly materials for construction. This flashing is manufactured from 100% recycled lead, which has a low carbon footprint and requires less energy to process.
Do I need special tools to install lead flashing?
While no adhesives are required, you will need basic roofing tools for cutting and shaping the lead, such as a lead dresser, bolster chisel, and a sharp knife or snips. Following LSA guidelines on technique is crucial.
What is patination oil and why is it necessary?
Patination oil is applied after installation to protect the lead surface from atmospheric attack, preventing the formation of white deposits. It helps the lead to form a stable, uniform patina, ensuring its aesthetic appeal and longevity. It is essential for maintaining the warranty.

Troubleshooting
White powdery substance forming on the lead surface
This is typically lead carbonate, a natural protective layer. Ensure patination oil was applied correctly after installation. If excessive, clean gently with a soft brush and reapply patination oil as per LSA guidelines.
Lead sheet appears to be stretching or tearing during installation
Ensure correct tools and techniques are used. Avoid excessive force. Lead is malleable but can be damaged if worked too aggressively. Use annealing if necessary for complex shapes, but typically Code 5 is pliable enough without it.
Water leakage detected after installation
Carefully inspect the lead flashing for any splits, gaps, or improperly dressed joints. Revisit the installation, ensuring all seams are correctly overlapped and dressed to create a continuous watertight barrier. Check for damage from external factors.

Setup, Compatibility & Care Instructions
Installation:
Ensure the substrate is clean, dry, and sound before application.
Cut the lead sheet to the required shape using appropriate tools.
Carefully dress and boss the lead to fit the contours of the roof structure, ensuring a snug fit without stretching or distorting the material unnecessarily.
For optimal weather tightness, minimize the number of laps and joints.

Care:
Patination Oil Application: After installation, all lead sheet must be coated with a suitable patination oil. This helps to create a uniform, stable protective layer, preventing unsightly white or grey powdery deposits (lead carbonate) and ensuring the long-term aesthetic and performance of the lead. Reapplication may be necessary periodically as per manufacturer guidelines.
Avoid abrasive cleaners or tools that could scratch the surface.
