Lead flashing plays a critical role in protecting your roof from water ingress, particularly at junctions where the roof meets walls, chimneys, or skylights. When installed and maintained correctly, lead flashing can last well over 50 years. However, neglecting even minor issues can compromise its effectiveness. At Kingswinford Roofing Repairs in Kingswinford, Staffordshire, we understand the long-term value of properly maintained flashing.
Why Lead Flashing Matters
Lead flashing is used because of its flexibility, durability, and resistance to corrosion. It forms a weatherproof barrier that prevents rainwater from seeping into vulnerable areas of your roof structure. When well-maintained, it offers unmatched longevity, making it a wise investment for both traditional and modern homes.
Common Causes of Lead Flashing Deterioration
Several factors can affect the lifespan of your lead flashing:
- Thermal movement: Expansion and contraction due to temperature changes can cause splits or lifting.
- Poor installation: Incorrect fitting can lead to premature failure.
- Corrosion: Exposure to pollutants or acidic rain can degrade the metal over time.
- Debris build-up: Organic matter and dirt can trap moisture and lead to decay in adjoining materials.
Maintenance Tips to Prolong the Life of Lead Flashing
To keep your lead flashing in excellent condition for decades, follow these practical steps:
Inspect Annually
- Look for signs of cracking, lifting, or splits.
- Pay special attention to flashing around chimneys, valleys, and roof edges.
- Check adjoining mortar joints for deterioration.
Clean the Surface
- Gently remove debris, moss, and algae using a soft brush and water.
- Avoid harsh chemicals or pressure washing, which can damage the surface and sealant.
Re-seal Joints
- Over time, joints between lead and brickwork can degrade. Re-point using a suitable mortar or lead sealant.
- Ensure the sealant remains flexible to accommodate movement.
Apply Patination Oil
- Patination oil helps protect lead from staining and corrosion.
- It should be applied after cleaning and during installation, then annually to maintain protection.
Secure Fixings
- Ensure lead flashing is mechanically fixed in place without restricting movement.
- Use clips or straps rather than nailing directly, which can cause cracking.
