Obsidian Roofing LTD provides fast, fully insured chimney repairs across London, including emergency callouts, chimney repointing, lead flashing repair, flaunching, and chimney stack restoration.
If your chimney is leaking, cracking, or showing signs of deterioration, it’s more than a cosmetic issue. In London, constant rain, freeze-thaw cycles, and strong winds often accelerate chimney damage, leading to water ingress, weakened mortar joints, and structural instability.

With 15+ years of hands-on roofing and masonry experience, our family-run team handles everything from minor chimney repointing to full chimney stack repair and emergency structural stabilisation across all London boroughs.

At Obsidian Roofing, we are the registered chimney contractors offering a service dedicated to keeping your chimney secure, effective, and durable. From chimney design and new chimney construction to full-scale repair and replacement, we bring years of experience and workmanship to each project.
A properly maintained chimney plays a crucial role in your residence, securely drawing out dangerous combustion gases, including carbon monoxide. Without routine upkeep, problems such as blockages, cracks, or failing leadwork may result in damp, subsidence, and even structural damage. For that reason, experienced roofers deliver proactive inspections and maintenance designed to pinpoint hidden issues before they intensify.
At Obsidian Roofing, we excel in chimney installation and dependable leadwork repairs, carried out swiftly and expertly. Cleaning services are available to prevent soot and creosote buildup, aiding in decreasing fire risks and elevating effectiveness.
If your chimney has not been inspected in recent years, we highly suggest scheduling a visit. Trust us as your go-to partner to keep your residence dry and warm throughout the year!

Chimneys are exposed structures. Over time, weather exposure, aging brickwork, and failing leadwork can compromise both the roofline and internal property structure. Our chimney specialists focus on restoring structural integrity, weatherproofing, and long-term durability.
Many homeowners delay chimney repairs because the damage appears minor from the outside. However, untreated chimney problems can lead to serious risks.
Some of the most common dangers include:
Falling masonry hazards
Loose bricks or unstable chimney stacks can collapse during storms or high winds.
Water ingress and internal damp
Once moisture enters the chimney structure, it spreads through the roof system and internal walls.
Carbon monoxide risk
Damaged chimneys or compromised flue liners can disrupt proper ventilation, increasing safety risks.
Roof structure damage
A leaking chimney can eventually weaken surrounding roof timbers.
Structural instability
Severely damaged stacks can lean or collapse if not repaired promptly.
That’s why early inspection and professional repair are critical.
At Obsidian Roofing, we follow a cautiously created procedure to guarantee your chimney installation is seamless, secure, and built to last. Here is how we make it happen:

The cost depends on the level of damage. Minor chimney repointing or small flashing repairs are typically lower cost, while chimney stack rebuilding or major structural repairs will require a larger investment. Most homeowners in London request an inspection first so we can provide a precise quote.
Professional roofing companies with masonry experience handle most chimney repairs. Roofers typically manage chimney stack repair, flashing replacement, repointing, and waterproofing because chimneys are part of the roof structure.
Common signs include:
Chimney flaunching is the mortar layer that seals the area around chimney pots at the top of the stack. It prevents rainwater from entering the chimney structure. Damaged flaunching is a common cause of chimney leaks and structural deterioration.
