To Protect Your Roof with Professional Lead Flashing Replacement Call 020 8776 1693
Lead flashing plays an essential role in keeping your roof watertight. Installed around chimneys, roof valleys, dormers, skylights and where roofing materials meet brickwork, it creates a durable weatherproof seal that prevents rainwater from entering your home.
Over time, lead flashing can deteriorate due to weather exposure, movement within the roof structure or poor installation. Once it begins to fail, water can quickly find its way beneath your roof covering, leading to damp, timber decay and costly structural damage.
At McColloch Roofing, we provide professional lead flashing replacement services for homeowners across the North East. Whether you’re dealing with persistent roof leaks or replacing ageing flashing as part of wider roofing work, our experienced team delivers high-quality workmanship designed to protect your property for years to come.

What Is Lead Flashing?
Lead flashing is a flexible sheet of lead installed in vulnerable areas of a roof where water could otherwise penetrate. It is commonly fitted around:
- Chimneys
- Roof valleys
- Dormer windows
- Skylights
- Roof abutments
- Extensions
- Wall junctions
Because lead is highly durable, weather resistant and flexible, it can accommodate natural building movement while maintaining a watertight seal. Properly installed lead flashing can last for decades, making it one of the most reliable roofing materials available.
However, even the highest quality lead eventually reaches the end of its lifespan or suffers damage from environmental conditions.
What Causes Lead Flashing to Fail?
Although lead is exceptionally durable, several factors can affect its performance over time.
Common causes include:
- Age-related deterioration
- Cracked or split lead
- Loose mortar joints
- Storm damage
- Incorrect installation
- Poor-quality repairs
- Thermal expansion and contraction
- Roof movement
- Corrosion caused by incompatible materials
Once flashing becomes damaged, water can enter beneath the roof covering and create problems that extend well beyond the roof itself.

Frequently Asked Questions
Can damaged lead flashing cause roof leaks?
Yes. Lead flashing creates a waterproof seal around vulnerable areas such as chimneys, roof junctions and valleys. If it becomes cracked, loose or worn, rainwater can seep beneath the roof covering, resulting in leaks, damp and structural damage if left untreated.
Should lead flashing be repaired or replaced?
It depends on the extent of the damage. Minor issues may be suitable for repair, but severely cracked, split or deteriorated flashing is usually best replaced to restore long-term protection. Our team will inspect your roof and recommend the most appropriate solution.
How long does lead flashing replacement take?
Most domestic lead flashing replacement projects can be completed within a day, although the timescale depends on the size of the affected area and whether additional roofing or chimney repair work is required.
How can I tell if my roof leak is caused by faulty flashing?
Leaks around chimneys, roof abutments or skylights are often linked to damaged flashing. Water stains on ceilings, damp patches in the loft or visible cracks in the lead are common indicators. A professional roof inspection can confirm the source of the problem.
Do you replace lead flashing as part of other roofing work?
Yes. Lead flashing replacement is often carried out alongside roof repairs, new roof installations and roofline improvements. If your gutters, fascias or soffits are also showing signs of wear, we can assess these during the same visit and recommend any necessary guttering, fascias & soffits work.
