The Leadworx Pitched Roof Slate is a premium lead weathering slate designed to provide a durable, weatherproof seal around flue pipes, soil pipes, boiler flues, or ventilation pipes where they penetrate through a slate or tiled pitched roof.

Crafted in Cornwall, Great Britain, each flashing is manufactured from 100% recycled Code 4 sheet lead, milled to British Standard **BS EN 12588** for consistency in thickness, flexibility, and performance.

## Description

### Description

**Made from Code 4 Lead** – Complies with BS EN 12588 for thickness tolerance and long-lasting performance.

**Angle-Specific Options** – Available in 5° pitch increments to closely match your roof’s angle and ensure a snug, watertight fit.

**Welded Spigot Design** – The upstand spigot is designed with a built-in tolerance of ±2.5°, ensuring easy installation on slightly uneven roofs.

**Handcrafted in the UK** – Proudly fabricated in Cornwall from sustainable, recycled lead.

### Common Size Guide for Pitched Slates

To assist in choosing the right pitched slate size, here are typical recommendations for twin-wall flue systems:
- **5-inch twin wall flue** → **190mm diameter roof slate**
- **6-inch twin wall flue** → **220mm diameter roof slate**
- **Typical sizes for 110mm soil pipes require 115mm lead slate**

**Important:** Always check the _external diameter_ of your pipe. The roof slate must have an internal spigot diameter _greater than_ the external diameter of your pipe for proper fitting.

### Lead Slate Size Guide – Soil Pipes, Flue Pipes & Twin-Wall Systems
1. **Determine Pipe Type**: Is it a stove flue, boiler vent, or soil/ventilation pipe?
2. **Measure External Diameter**: Use a tape measure to find the external diameter of the pipe where it will pass through the roof.
3. **Match to Slate Size**:
   - Ensure the roof slate’s internal spigot diameter is larger than the pipe’s external diameter.
   - Select the correct pitch angle of your roof in 5° increments (e.g., 25°, 30°, 35°).
4. **Still Not Sure?** If in doubt, please contact us with your pipe dimensions and roof pitch, we can help confirm the correct size or fabricate a bespoke flashing tailored to your needs.
