Lead Flashing Repair Thornbury

Professional Roofing and Leadwork Specialists

A watertight roof is essential for protecting your home or business from leaks, damp and structural damage. One of the most important components in maintaining a dependable roofing system is the lead flashing. At Fortress Roofing, we provide expert lead flashing repair in Thornbury, delivering long-lasting, reliable solutions backed by years of craftsmanship and industry experience. Whether you are dealing with a small leak or significant flashing deterioration, our team is ready to help restore the integrity of your roof.

The Importance of High-Quality Lead Flashing

Lead flashing plays a critical role in safeguarding vulnerable roof junctions. It is used around chimney stacks, walls, roof valleys, dormers, skylights and other transition points to prevent water from entering the building. Lead is favoured for these areas because it is durable, flexible and able to withstand the harshest weather conditions.

Even so, lead flashing can deteriorate over time due to age, storm exposure, building movement or poor installation. When flashing fails, water quickly finds a way into your property, often resulting in expensive damage to ceilings, insulation, plaster and internal structures. Addressing flashing issues promptly is the best way to protect your home and avoid larger repair bills in the future.

Signs Your Lead Flashing Needs Repair

Not all roofing problems are immediately visible, but there are several clear indications that your lead flashing may require attention. If you notice any of the following issues, it is advisable to contact a specialist for a professional assessment:

• Water staining on ceilings or walls
• Damp patches during or after rainfall
• Visible cracks, splits or tears in the lead
• Flashing that has lifted or pulled away from the roof surface
• Loose or missing mortar around chimney flashing
• Corrosion, warping or sagging lead
• Drips appearing internally near chimneys or walls

These symptoms can escalate quickly if not addressed, making timely repairs essential.

Our Lead Flashing Repair Services in Thornbury

Fortress Roofing provides comprehensive lead flashing repair solutions tailored to the needs of each property. Our services are designed to restore watertight performance while ensuring long-term durability and a professional finish.

Thorough Inspection and Assessment

Before carrying out any work, our team performs a detailed inspection of the affected area. This includes assessing the condition of the flashing, checking surrounding materials and identifying any contributing issues such as mortar failure or roof damage. Understanding the root cause allows us to recommend the most effective repair strategy.

Lead Flashing Repairs

Where possible, we repair existing flashing by resealing, refixing or reshaping the lead to ensure a secure and watertight fit. Minor cracks or splits can often be resolved with specialised sealing techniques or replacement of smaller sections. Our aim is always to preserve what can be saved while ensuring the long-term performance of your roof.

Complete Lead Flashing Replacement

For flashing that is severely damaged, incorrectly installed or beyond repair, we offer full replacement using high-quality lead. Our team installs new flashing following correct industry standards, ensuring proper expansion joints, secure fixing and precise shaping to match the contours of your roof. A professional installation not only prevents leaks but also maximises the lifespan of the roofing system.

Chimney Flashing Repairs

Chimneys are one of the most common sources of leaks, often due to worn step flashing, faulty soakers or deteriorated mortar. We provide complete chimney flashing repairs in Thornbury, addressing all elements including apron flashing, back gutters and mortar repointing. This ensures a fully watertight finish around the chimney stack.

Mortar Repointing and Finishing

Deteriorated mortar can allow water to penetrate behind the flashing. When required, we repoint mortar joints using high-strength, weather-resistant materials designed to withstand long-term exposure. This adds an additional layer of protection against water ingress.

Emergency Lead Flashing Repairs

If you are dealing with an active leak or urgent flashing failure, we offer rapid response emergency repair services. Our priority is to prevent further damage by restoring weatherproofing as quickly as possible while ensuring the repair is completed to a high standard.

What Causes Lead Flashing Damage?

Understanding the cause of flashing damage can help prevent similar issues from occurring in the future. Common factors include:

• Weather Exposure: Constant rain, wind and temperature changes cause gradual wear and fatigue.
• Storm Damage: High winds can dislodge flashing or lift roofing materials around it.
• Poor Installation: Incorrect fitting, insufficient sealing or use of unsuitable materials often leads to early failure.
• Thermal Movement: Seasonal expansion and contraction can stress the lead over time.
• Mortar Breakdown: Cracked or crumbling mortar compromises the seal between flashing and brickwork.

At Fortress Roofing, our repair techniques address both the symptoms and the underlying cause to ensure long-lasting results.
