Installation Process
Installing your Lead Slate is straightforward with the right preparation and tools. Begin by ensuring that the roof area around the flue pipe is clean and free of debris. The installation process involves the following steps:
1. Prepare the Roof Surface:
- Clear all debris and inspect the area to ensure the roof pitch is within the suitable range.
- Check that the flue pipe dimensions match the product specifications.
2. Position the Lead Slate:
- Place the slate around the pipe ensuring that it aligns perfectly with the roof surface. This alignment is critical to maintaining a consistent seal.
- If necessary, adjust the slate to accommodate any minor deviations in roof shape or flue pipe alignment.
3. Secure with Lead Solder:
- Use an appropriate lead solder to affix the slate firmly to the surrounding roof area.
- If you encounter any gaps or irregularities, refer to additional accessories such as extra flashing kits or sealing tapes that are available to further enhance the protective seal.
4. Final Inspection:
- Once installed, check the slate from different angles to ensure there are no gaps or potential leak points.
- Allow time for the solder to set and solidify, ensuring maximum integrity of the seal.
