Lead flashing is a crucial component in the roofing of many older homes in Sutton in Ashfield, Nottinghamshire. It is used to direct water away from areas where the roof meets vertical surfaces, such as chimneys, skylights, or walls. Over time, however, lead flashing can become worn, damaged, or deteriorate, which can lead to leaks and other structural issues. In this blog post, we’ll explain why lead flashing is so important for older roofs, how to identify problems, and what you can do to ensure your roof remains in good condition.
What Is Lead Flashing and Why Is It Important?
Lead flashing is a strip of lead used to seal the joints and gaps on a roof to prevent water from seeping into vulnerable areas. It is most commonly found where the roof meets a wall, chimney, or other roof projections. Lead is chosen for flashing because it is highly durable, flexible, and resistant to the elements, making it an excellent material for keeping water out of the roof structure.
Key Roles of Lead Flashing:
- Waterproofing: Flashing directs water away from critical areas to prevent leaks.
- Protecting vulnerable areas: It protects the areas where the roof meets walls, chimneys, and other roof projections, which are common entry points for water.
- Durability: Lead is flexible and can expand and contract with the roof, preventing cracks or gaps that could let water in.
How Lead Flashing Affects Older Roofs
Lead flashing is particularly important on older roofs, as older buildings may not have been built with modern waterproofing techniques. Over the years, flashing can deteriorate due to weather conditions, exposure to the elements, and natural wear and tear. Understanding how to maintain or replace your lead flashing can help prevent more serious damage down the line.
Common Issues with Lead Flashing on Older Roofs:
- Corrosion and Wear: Lead can corrode or weaken over time, especially in areas where it is exposed to the elements for long periods. If left unchecked, this can lead to leaks and damage to the underlying roof structure.
- Movement and Settling: Over time, a building may settle, which can affect the positioning of the flashing. This can cause gaps to form where water can seep in.
- Cracks and Gaps: Lead flashing can crack, especially if it has been exposed to temperature extremes or weathering over the years. When the flashing is cracked, water can find its way into the roof, leading to leaks.
- Improper Installation: On older homes, the flashing may not have been installed correctly, which can lead to gaps or uneven surfaces that allow water to enter.
Signs Your Lead Flashing Needs Attention
It’s essential to regularly inspect your roof and lead flashing for signs of wear or damage. Catching problems early can prevent larger, more costly repairs in the future.
Signs to Look Out For:
- Water stains or damp patches: If you notice water stains on your ceiling or walls near roof joints, it’s likely that water is getting through damaged flashing.
- Loose or damaged flashing: If the flashing is loose, cracked, or appears to be shifting, this can be a clear sign that it needs repair or replacement.
- Visible corrosion: Corroded or pitted flashing can no longer provide a proper seal and may need to be replaced.
- Leaking around chimneys or vents: If you experience leaks around these areas, the flashing could be damaged, allowing water to enter.
How to Maintain or Replace Lead Flashing
If you have an older roof with lead flashing, regular maintenance and prompt repairs are key to preventing serious damage. Here are a few steps to ensure your flashing remains in good condition:
1. Regular Inspection
It’s important to inspect your roof regularly, particularly after severe weather. Checking the flashing at least once or twice a year can help catch any issues before they become significant problems.
- Check for visible damage: Look for cracks, corrosion, or signs of movement in the lead flashing.
- Look for water stains: Check your ceilings, walls, and attic for any signs of water penetration.
2. Repairing Damaged Flashing
If you find any cracks or gaps in your lead flashing, it’s important to address them quickly to prevent further damage. Depending on the severity of the issue, it may be possible to repair the flashing by re-sealing it or patching up small cracks.
- Use lead sealant: For minor cracks, you can use lead sealant to fill in the gaps.
- Replace sections of flashing: If the flashing is too damaged, it may need to be replaced entirely. This can involve removing the old flashing and installing new lead flashing.
3. Full Replacement
If your lead flashing is beyond repair, it will need to be replaced. A full replacement involves removing the old flashing and installing a new layer, ensuring it is properly sealed and fitted to prevent water ingress.
- Professional installation: Replacing lead flashing should always be done by a professional to ensure it’s installed correctly.
- Ensure proper sealing: Proper sealing ensures that no gaps are left where water can seep through.
