What Is Lead Flashing and Why Is It Important?
Lead flashing is one of the most vital components of a roofing system. It acts as a protective barrier, sealing joints and preventing water from seeping into vulnerable areas of the roof. Typically found around chimneys, valleys, skylights, and where roofs meet walls, lead flashing ensures that rainwater is directed away from entry points, safeguarding the structure of the property. At LS Roofing Staines-upon-Thames, we understand how essential properly installed and maintained flashing is to the long-term protection of homes in Surrey.
The Benefits of Using Lead for Flashing
Lead has remained the material of choice for flashing for centuries due to its unique properties.
- Durability – Lead can withstand decades of exposure to the elements without significant deterioration.
- Flexibility – It can be moulded to fit different roof shapes and details with precision.
- Weather Resistance – Lead resists corrosion, making it ideal for the damp British climate.
- Low Maintenance – With correct installation, lead flashing requires minimal attention to remain effective.
These qualities make lead flashing an invaluable part of roofing systems across Staines-upon-Thames and the wider Surrey area.
Professional Installation of Lead Flashing
Correct installation is critical to ensure flashing performs as intended. Poorly fitted flashing can allow water ingress, leading to internal damage. The process typically involves:
- Preparing the roof surface for a clean, secure bond.
- Cutting grooves into brickwork or mortar joints where required.
- Shaping the lead to fit the joint perfectly.
- Fixing and sealing the flashing to create a watertight finish.
With professional installation from LS Roofing Staines-upon-Thames, homeowners can be confident that their flashing will stand up to years of exposure without failure.
Common Issues with Lead Flashing
Over time, even durable materials like lead may require attention. Homeowners should be aware of common issues that affect flashing, including:
- Cracking or splits caused by thermal expansion and contraction.
- Loose sections where fixings or mortar have failed.
- Corrosion or staining in areas with excessive water exposure.
- Leaks around chimneys or roof valleys, often due to damaged flashing.
Spotting these problems early is crucial. LS Roofing Staines-upon-Thames provides thorough inspections and repair services to restore the effectiveness of flashing before further damage occurs.
