Lead flashing is one of the most vital yet often overlooked components of your roofing system. Positioned around chimneys, roof valleys, dormers and joints, lead flashing acts as a waterproof barrier, directing rainwater away from vulnerable areas where the roof meets other structures. When this barrier fails, water can find its way inside—causing costly damage before you’re even aware of a problem.
At Lee-on-the-Solent Roofing Repairs, we provide professional lead flashing repair services throughout Lee-on-the-Solent, Hampshire to help homeowners protect their property and prevent leaks before they begin.
What Is Lead Flashing and Why Is It Used?
Lead flashing is a highly durable and flexible material used to seal gaps and joints on your roof. It’s particularly effective at creating weatherproof connections where different surfaces meet, such as around chimneys, roof junctions and skylights.
Key advantages of lead flashing:
- Long lifespan with proper installation
- Excellent malleability for complex roof shapes
- High resistance to corrosion and UV damage
- Creates a watertight seal against rain and wind
When installed and maintained correctly, lead flashing can perform for decades—making it a smart long-term investment in your home’s integrity.
Signs Your Lead Flashing May Need Repair
Over time, exposure to the elements and natural ageing can cause lead flashing to deteriorate. Detecting problems early is essential for preventing water ingress and avoiding extensive interior damage.
Common warning signs include:
- Cracks or splits in the lead
- Lifting or peeling away from the brickwork
- Visible rust or staining near joints
- Water stains inside the loft or ceiling below
- Damp patches on internal walls near the roofline
If you notice any of these issues, prompt action from Lee-on-the-Solent Roofing Repairs can prevent further deterioration and protect your home in Lee-on-the-Solent, Hampshire.
What Happens If Flashing Fails?
When lead flashing is compromised, water can seep behind the roof covering and make its way into the underlying structure. This not only risks damage to timbers and insulation but also creates conditions for mould and damp.
Potential consequences of failed flashing:
- Damp patches on ceilings or loft insulation
- Rotten roof timbers and weakened structure
- Staining or bubbling paintwork on upper floors
- Growth of mould or mildew in warm, damp areas
These problems are often avoidable with timely repairs carried out by experienced roofing specialists.
The Lead Flashing Repair Process
Professional lead flashing repairs require precision and experience. At Lee-on-the-Solent Roofing Repairs, we follow industry best practices to ensure long-lasting results tailored to the needs of each property.
Our typical repair approach includes:
- Careful inspection of the affected area
- Removal of loose or damaged lead
- Re-dressing or replacing lead flashing to ensure proper fit
- Sealing joints with appropriate fixings and pointing materials
- Ensuring correct overlap and water runoff
In many cases, we can repair or replace only the affected sections rather than the whole installation, saving you time and cost.
Preventative Maintenance Tips
Regular maintenance can help extend the life of your lead flashing and reduce the risk of emergency repairs.
Simple ways to protect your flashing:
- Schedule annual roof inspections, especially after storms
- Keep gutters and valleys clear of leaves and debris
- Look for signs of movement or shifting in adjacent roof tiles
- Monitor attic spaces for signs of moisture or staining
With routine checks and early intervention, your flashing can remain a strong line of defence against water ingress.
