Lead flashing is an essential component of any roofing system, playing a crucial role in preventing water ingress at joints and intersections, such as around chimneys, vents, and roof valleys. Despite its durability, lead flashing is not immune to wear and tear, and when it fails, it can lead to significant problems for your home. At Edenbridge Roofing Repairs, based in Edenbridge, Kent, we specialise in identifying and resolving issues related to lead flashing, ensuring your roof remains watertight and secure.
Understanding Lead Flashing and Its Importance
Lead flashing is used to create a waterproof barrier at critical points where different sections of the roof meet or where the roof connects with other structures. It is highly valued for its flexibility, malleability, and longevity, often lasting several decades when properly installed. However, over time, lead flashing can develop issues that compromise its effectiveness, leading to leaks and water damage.
Common Causes of Lead Flashing Failures
Several factors can contribute to the failure of lead flashing, including:
- Age and Weathering: Over time, exposure to the elements can cause lead flashing to deteriorate. Harsh weather conditions, such as heavy rain, snow, and high winds, can accelerate this process, leading to cracks, splits, or corrosion in the flashing.
- Poor Installation: Incorrect installation is a common cause of lead flashing failure. If the flashing is not securely fixed or is improperly positioned, it can become loose or misaligned, allowing water to seep through the gaps.
- Thermal Movement: Lead expands and contracts with temperature changes. If there isn’t enough room for this movement, the flashing can crack or pull away from the surfaces it is meant to protect, creating entry points for water.
- Physical Damage: Lead flashing can be damaged by external forces such as falling debris, foot traffic on the roof, or even birds pecking at it. Any physical damage can compromise the integrity of the flashing and lead to leaks.
How to Spot Lead Flashing Failures
Early detection of lead flashing issues can save you from costly repairs down the line. Here are some signs that your lead flashing may need attention:
- Water Stains on Ceilings or Walls: Discolouration or damp patches on interior walls or ceilings, particularly near chimneys or roof valleys, can indicate a flashing problem.
- Visible Cracks or Splits: Inspect the flashing for any visible cracks, splits, or corrosion, especially around joints and seams.
- Loose or Missing Flashing: If the flashing appears to be loose, misaligned, or completely missing, it’s likely that it has failed and needs to be replaced.
- Moss or Mould Growth: Excessive moss or mould growth around the flashing area can trap moisture against the lead, leading to accelerated deterioration.
Fixing Lead Flashing Issues
When lead flashing problems are identified, it’s essential to address them promptly to prevent further damage. At Edenbridge Roofing Repairs, we offer a range of solutions to fix common lead flashing issues:
- Repairing Minor Cracks and Splits: For small cracks or splits, we can apply specialised lead sealants or repair patches to restore the flashing’s integrity.
- Re-securing Loose Flashing: If the flashing has become loose, we will re-secure it using appropriate fixings, ensuring it is correctly positioned to provide maximum protection.
- Replacing Damaged Flashing: In cases where the flashing is severely damaged or corroded, replacement may be necessary. We use high-quality lead flashing to ensure a long-lasting solution.
- Preventative Maintenance: Regular inspections and maintenance can help prevent lead flashing failures. Our team can carry out routine checks to identify potential issues before they develop into serious problems.
