What are lead flashing rolls used for?

Lead flashing rolls are used to weatherproof roof junctions and transitions where roofs meet masonry, chimneys, parapets and structural upstands. Because lead is highly malleable and naturally corrosion resistant, it can be dressed into complex roof details while still allowing for thermal movement.

Choosing the correct lead flashing roll

Selecting the correct lead flashing roll depends on the exposure, depth of the detail, required durability and whether the lead remains exposed or concealed.

Lead code Typical use Approx. weight
Code 3 Soakers and concealed details 14.97 kg/m²
Code 4 Standard exposed flashings 20.41 kg/m²
Code 5 Deeper flashings and wider details 25.40 kg/m²
Code 6 Heavy-duty and heritage applications 30.05 kg/m²

For many everyday roofing details, Code 4 lead flashing rolls remain the standard specification. Where greater durability, deeper cover or more exposed detailing is required, Code 5 lead rolls are commonly preferred.
