Lead Flashing Repair Under Dormer Window on Slate Roof in Swarkestone, Derby

Common Issues with Lead Flashing on Slate Roofs

Lead flashing is a crucial component in roofing, particularly around dormer windows, as it helps prevent water ingress. Over time, exposure to the elements, thermal movement, and general wear can cause lead flashing to shift out of place. Homeowners in Swarkestone, Derby, often experience this issue, especially in older properties where materials have weathered over time.

Causes of Lead Flashing Movement

Several factors can contribute to the movement of lead flashing, including:

Thermal expansion and contraction: Lead expands and contracts with temperature changes, which can cause it to loosen over time.
Poor installation: If the flashing was not secured correctly initially, it may be prone to slipping.
Storm damage: High winds and heavy rain can dislodge flashing, particularly around dormer windows.
General ageing: As buildings settle and age, minor structural shifts can affect roof components.

Steps to Repair Lead Flashing Under a Dormer Window

Fixing a shifted lead flashing involves several steps to ensure a watertight and long-lasting repair:

Inspection: A professional roofer will assess the extent of the damage and check for any signs of water ingress or damage to the underlying slate tiles.
Re-securing the flashing: In cases where the lead is still in good condition, it may be possible to reposition and re-secure it using lead clips or lead sealant.
Replacement: If the flashing is damaged or worn, it may be necessary to replace it with new code-compliant lead sheeting.
Sealing: High-quality sealants, such as lead mate sealant, are used to prevent water penetration and ensure longevity.
Testing: Once repairs are completed, a thorough water test may be conducted to ensure no leaks remain.
