Why choose Code 3 180mm 3m Roofing Lead?

Code 3 180mm 3m Roofing Lead gives you extra width for details that need more cover than 150 mm provides,
while keeping the handling benefits of Code 3. Supplied in a convenient 3 m roll, this size is ideal for
stepped and cover flashings on deeper chases, wider chimney aprons, larger tile/slate soakers, and small weatherings where
a light, easily dressed sheet is appropriate. The Code 3 gauge offers a practical balance of weight and workability
when the lead is functioning primarily as a weathering rather than a loaded deck.

Typical uses for Code 3 180mm 3m Roofing Lead

• Wider stepped or cover flashings where additional lap is required.
• Chimney aprons and back gutters (within sensible single-piece lengths).
• Individual soakers for larger slate/tile formats and generous headlaps.
• Small upstands, cills and protection pieces needing extra coverage.
• General detailing on dormers and abutments where agility on the scaffold matters.

Good practice with Code 3 180mm 3m Roofing Lead

Keep piece lengths sensible to manage movement and avoid fatigue, especially on sun-exposed elevations.
Dress neatly into the chase and complete with suitable pointing (mortar or neutral-cure sealant).
Use clips/straps and mechanical fixings sparingly and keep them out of movement zones. For bay roofs, parapets,
heavily trafficked areas or where pieces perform as coverings, step up to heavier gauges (e.g., Code 4/5) as required.

Installation essentials

1. Prepare the substrate: Provide a smooth bearing and remove sharp edges. Use a slip layer beneath wider weatherings.
2. Set out & cut: Measure runs accurately; cut Code 3 180mm 3m Roofing Lead with clean edges for tight laps.
3. Fix with care: Use copper or stainless fixings/clips; avoid over-nailing and do not bridge movement joints.
4. Finish the chase: Point or seal for a crisp, durable joint that sheds water.
5. Protect new work: Consider patination oil on visible areas to limit early carbonate staining and promote an even tone.
