The chimney is one of the most vulnerable parts of any Dublin roof, constantly exposed to wind, rain, and frost. When the mortar cracks or the lead flashing fails, it becomes a major source of leaks and structural damage to your home.
At Capital Roofers, we specialise in all aspects of chimney repair in Dublin, from simple repointing and lead flashing replacement to full chimney stack rebuilds. Our skilled team ensures your chimney is structurally sound, watertight, and fully compliant with all safety standards.
Most homeowners don't realise that many "roof leaks" are actually caused by a fault in the chimney structure or its surrounding components. Over time, the movement of the building and exposure to weather causes deterioration in specific areas:
Lead Flashing: If the lead is cracked or lifted where the chimney meets the roof, water channels directly into your roof space.
Mortar Joints: Loose or 'washed out' mortar between bricks allows water to soak into the masonry, causing damp and decay.
Chimney Pot/Capping: A damaged or missing pot/capping lets rainwater pour straight down the flue and into your attic.
Stack Structure: Bricks that are flaking (spalling) or a leaning stack indicate structural instability and a collapse risk.
Chimney work is specialised and often high-risk. You need a contractor with expertise in both roofing and masonry.
Dual Expertise: We are skilled in both the masonry (bricks and mortar) and the roofing side (flashing and slate/tile integration) of the chimney, ensuring a complete, leak-proof solution.
Safety First: All work is carried out to the highest safety standards, using appropriate access equipment and full insurance coverage.
Local & Fast: We are based in Dublin and offer a prompt response for urgent structural concerns or sudden leaks around the chimney.
Free Written Quote: After a detailed inspection, you receive a clear, written quote before we start. No hidden fees, just honest work.
The cost varies significantly depending on the repair required. Simple lead flashing repair or minor repointing is generally affordable, costing a few hundred euros. However, structural issues, like rebuilding a leaning stack or replacing extensive mortar joints, will cost more due to the labour and scaffolding involved. We always provide a free, on-site inspection to accurately diagnose the problem and give you a clear, written, no-obligation quote before any work begins.
Chimney leaks are often characterised by damp patches appearing on ceilings or walls near the chimney stack, especially after heavy, wind-driven rain. If the leak occurs directly under the slates or tiles and is widespread, it may be the roof itself. During our free inspection, we climb up to safely check the critical areas around your chimney—the flashing, mortar joints, and capping—to determine the exact source of water ingress.
If water is actively leaking into your attic or damaging your ceiling, we treat it as an emergency. We aim to offer a same-day response for urgent chimney leaks across Dublin. Our goal is to quickly access the chimney and apply a safe, temporary seal (like a weatherproofing membrane) to stop the water damage immediately, followed by a permanent repair once the weather allows.
In most cases, yes, particularly for work that involves repointing, replacing large sections of flashing, or any structural brickwork. Using proper scaffolding is the safest and most effective way to access the stack, ensuring our roofers can work accurately and compliantly. We arrange and manage all scaffolding requirements for the job.
