Why choose Code 3 180mm 3m Roofing Lead?

Code 3 180mm 3m Roofing Lead is a go-to width for stepped/cover flashings and for cutting individual
slate/tile soakers. At roughly 1.32 mm thick, Code 3 remains light, easy to cut and fast to dress neatly into
chases—perfect for day-to-day abutment detailing where the sheet is acting primarily as a weathering. If you’re brushing up on
sequencing and technique, the training hub at
The Lead Lads covers practical methods, tools and layout.

Typical uses for Code 3 180mm 3m Roofing Lead

• Stepped flashings to brick or stone abutments on slate/tile roofs.
• Cutting individual slate/tile soakers quickly and economically from one roll.
• Cover flashings to dormer cheeks/heads and small upstands.
• Protective checks around openings and cills where a crisp line matters.
• Refurbishment details needing clean dressing and light handling.

Planning & set-out

Confirm exposure, required lap and chase depth before cutting. The 180 mm width of
Code 3 180mm 3m Roofing Lead offers ample cover for most abutments and for producing standard soakers. Keep
single-piece flashing lengths sensible for thermal movement and align joints with steps, drips and outlets. For real-world casework
showing how these details present in practice, see
Neal Roofing — Leadwork.

Good practice with Code 3 180mm 3m Roofing Lead

Use clips/straps and mechanical fixings sparingly, positioned outside movement zones; don’t over-nail or bridge joints.
Maintain clear drainage paths; add a smooth slip layer beneath any wider weatherings you form from this roll. If your piece becomes a
covering rather than a flashing (e.g., small bay/apron subject to load), step up to heavier gauges like Code 4 or Code 5.
Finish visible work with Patination Oil for even early tone.

Installation essentials

1. Prep the substrate: Smooth bearing; remove sharp edges. Brush dust from chases before inserting the flashing.
2. Cut & dress: Mark and cut Code 3 180mm 3m Roofing Lead; dress evenly into chases with tidy arrises.
3. Restrain neatly: Use Hall Clips or a Stainless Fixing Strip for fast, even restraint.
4. Finish the joint: Point with mortar or apply Lead Mate Sealant (neutral-cure) for a clean, weather-tight finish.
5. Protect presentation: Apply Patination Oil 0.5L on visible elevations to reduce early staining.

Soakers from 180 mm rolls — quick guide

Mark soaker lengths to suit tile/slate gauge with appropriate laps; cut multiple pieces from the
Code 3 180mm 3m Roofing Lead roll for speed and consistency. Dress the turn-ups neatly against the abutment, keep
fixings minimal, and ensure the overlying course sheds clear. For principle-led guidance aligned with recognised best practice, see
our standards explainer at
The Lead Lads — BS 6915 overview.
