Lead Roofing Cornwall | Chimney Flashing, Roof Valleys & Leadwork | SMK Roofing

Lead has been used in roofing for hundreds of years, and for good reason. Its exceptional durability, flexibility and weather resistance make it one of the most reliable materials available for protecting vulnerable areas of a roof.

Whether it's around chimneys, roof valleys, dormer windows or abutments, professionally installed lead flashing and leadwork play a vital role in keeping your property watertight.

At SMK Roofing, we provide expert lead roofing services throughout Cornwall, carrying out everything from new lead installations to repairs and replacement work using traditional methods and high-quality craftsmanship.

What Is Leadwork?

Leadwork refers to the installation and shaping of sheet lead to create waterproof seals where different parts of a roof meet.

Common applications include:

• Chimney flashing
• Step flashing
• Apron flashing
• Valley gutters
• Box gutters
• Dormer window flashing
• Roof abutments
• Parapet walls
• Flat roof details
• Bay window roofs

These areas experience some of the highest levels of water exposure, making correctly installed leadwork essential for preventing leaks.

Why Is Lead Still the Best Roofing Material?

Despite advances in modern building materials, lead remains one of the most trusted roofing products available.

Lead offers:

• Exceptional durability
• A lifespan of over 100 years when correctly installed
• Outstanding weather resistance
• Excellent flexibility around complex roof shapes
• Low maintenance requirements
• A traditional appearance suitable for both modern and period properties
• Resistance to corrosion

Its ability to expand and contract with changing temperatures makes it ideal for the varied weather conditions experienced across Cornwall.

Chimney Lead Flashing

One of the most common causes of roof leaks is damaged or poorly installed chimney flashing.

Over time, lead flashing can:

• Lift away from brickwork
• Crack due to incorrect installation
• Become loose in strong winds
• Suffer from poor previous repairs
• Allow water to penetrate the roof structure

At SMK Roofing, we carefully remove defective flashing before installing new code-approved lead using traditional techniques to provide long-lasting protection.

Roof Valleys

Roof valleys collect large volumes of rainwater, making them one of the most important waterproofing features on any roof.

Lead valleys provide:

• Excellent water flow
• Long-term durability
• Resistance to standing water
• Attractive traditional appearance

Whether you're repairing an existing valley or installing a new roof, professionally fitted lead valleys provide reliable protection for decades.

Traditional Craftsmanship Matters

Lead isn't simply cut and fixed into place.

Professional leadwork requires specialist knowledge of:

• Expansion joints
• Correct fixing methods
• Lead welding
• Bossing techniques
• Appropriate code thicknesses
• Weathering details
• Thermal movement

Incorrect installation can cause premature cracking, splitting or water ingress.

Our experienced roofers use proven traditional methods alongside modern best practices to ensure every installation performs exactly as intended.

Signs Your Leadwork Needs Attention

Many homeowners don't realise their lead flashing is failing until water begins entering the property.

Common warning signs include:

• Water stains around chimney breasts
• Damp patches in loft spaces
• Missing mortar around flashing
• Visible cracks in lead
• Lead lifting away from brickwork
• Loose flashing after storms
• Water running down internal walls

Early repairs can often prevent far more expensive structural damage later.

Lead Repairs or Full Replacement?

Not all damaged leadwork requires complete replacement.

Following a thorough inspection, we can advise whether your lead can be:

• Repaired
• Re-dressed
• Re-fixed
• Re-pointed
• Patched where appropriate

Where lead has reached the end of its service life, we'll recommend a complete replacement using the correct specification for your roof.

Cornwall is home to many beautiful period properties, listed buildings and traditional cottages where sympathetic repairs are essential.
