Why choose Code 3 360mm 3m Roofing Lead?

Code 3 360mm 3m Roofing Lead strikes a sweet spot for deeper flashings and compact aprons that need more
cover than 240–300 mm strips but don’t justify stepping up to very wide rolls. At ~1.32 mm thick, this code remains
light, easy to cut and quick to dress into chases, returns and checks—ideal for refurbishment work and crisp presentation on visible elevations.

The Lead Lads training articles and guides.

Typical uses for Code 3 360mm 3m Roofing Lead

• Deeper cover flashings to brick/stone abutments and parapet upstands.
• Small apron pieces and back gutters (limit single-piece lengths for movement control).
• Weatherings around dormers and rooflight kerbs where extra lap/tolerance is helpful.
• Protective checks around openings, cills and transitions on pitched roofs.
• Efficient cutting of individual slate/tile soakers from one roll.

Planning & set-out

The 360 mm width of Code 3 360mm 3m Roofing Lead offers generous lap while keeping handling straightforward.
Begin by confirming exposure, chase depth and required laps; then set sensible single-piece lengths so joints align with steps, drips and outlets.
Where long straight runs are specified, consider whether a 6 m product elsewhere in the project reduces joint count; on awkward geometries,
shorter pieces usually dress cleaner. For real-world examples of lead detailing in use, review

Good practice with Code 3 360mm 3m Roofing Lead

Use mechanical fixings sparingly and outside movement zones; don’t over-nail or bridge joints. Provide a smooth
slip layer beneath wider weatherings to enable free expansion/contraction and minimise underside abrasion.
Where the sheet acts as a covering (bay panels, parapets subject to load/foot traffic), step up to heavier gauges like Code 4 or Code 5.
Finish visible work with Patination Oil to reduce early staining while the patina establishes.

Installation essentials

1. Prepare the substrate: Provide a smooth bearing and remove sharp edges. Include a slip layer for wider pieces.
2. Set out & cut: Measure accurately and cut Code 3 360mm 3m Roofing Lead with clean edges for consistent laps.
3. Fix with care: Use copper or stainless fixings/clips; keep them out of movement zones and avoid over-nailing.
4. Finish the chase: Point with mortar or use Lead Mate Sealant for a neat, water-shedding joint.
5. Protect new work: Apply patination oil on visible elevations for even early tone and presentation.

Selecting the right code & when to step up

Code 3 360mm 3m Roofing Lead excels on deeper flashings and small aprons where agility and neat dressing matter.
If pieces will carry load, face high exposure, or form part of a covering (e.g., bays/parapets), specify a heavier code. Correct code selection,
combined with thoughtful bay sizing, movement control and drainage, underpins long service life. For principle-led guidance that maps to recognised practice,
