Why Chimneys Leak
Chimney leaks in Dublin properties usually stem from a few common causes. Understanding these helps us trace the problem quickly and fix the chimney flashing properly.
Lead Fatigue & Cracking
Lead flashing expands and contracts with temperature changes. Over time, this causes cracks or splits, allowing water in.
Poor Detailing
Flashing installed incorrectly or without proper overlaps and seals will leak when tested by wind-driven rain.
Mortar Failure
Pointing around the chimney base deteriorates over time, creating gaps for water to seep through into the roof space.
Debris & Blocked Gutters
Leaves and moss collect near chimneys, blocking drainage and causing water to back up under flashing.
Wind-Driven Rain
In Dublin's weather, wind pushes rain horizontally into gaps that would otherwise stay dry. Chimneys are particularly exposed.
Our Chimney Flashing & Repair Process
Inspect & Locate Entry
We inspect the chimney, flashing, and surrounding roof to identify the exact entry point of the leak. We check lead condition, mortar pointing, and drainage around the chimney base.
Make-Safe If Needed
If possible, we apply a temporary seal or patch to stop active leaks while we prepare materials and a detailed quote for the permanent repair.
Repair & Tidy Finish
We repair or replace the flashing detail using proper leadwork techniques, re-point where needed, and ensure a watertight seal. Photos provided on request.
All work is explained upfront with a clear written quote. No surprises, no pressure.

Frequently Asked Questions
What causes chimney leaks in Dublin homes?
Chimney leaks in Dublin homes are most commonly caused by failed or damaged lead flashing, the metal seal between the chimney stack and the surrounding roof. Over time, lead can crack, split, or pull away from the brickwork due to thermal expansion, weathering, or poor original installation. Mortar pointing around the chimney base can also deteriorate, allowing water to seep through. In some cases, the chimney stack itself may be porous or have damaged brickwork. Wind-driven rain is particularly problematic in Dublin’s climate, as it pushes water into gaps that would stay dry in calm conditions. When you search for chimney repair near me, you want a roofer who inspects all these areas to pinpoint the exact cause of the leak before recommending a repair and that’s exactly what we do.
Can you fix chimney flashing without rebuilding the chimney?
Yes, in most cases. To fix chimney flashing, we rarely need to rebuild the chimney stack itself. If the lead flashing is damaged, we can often patch or replace the affected section without disturbing the brickwork. If the mortar pointing around the chimney base has failed, we can re-point just those areas. Only in cases where the chimney stack is structurally unsound, severely damaged, or actively leaning would a rebuild be necessary, and if that’s the case, we’ll explain why and provide options. Most chimney leaks we repair in Dublin are purely flashing or pointing issues and can be resolved without major structural work.
Do you provide photos and written quotes for chimney repairs?
Yes, absolutely. After inspecting the chimney and identifying the source of the leak, we take photos showing the damaged flashing, pointing, or other issues. These photos are useful for your records, insurance claims, or landlord documentation. We then provide a clear written quote that breaks down the repair work, materials, and costs. If we carry out a temporary make-safe repair during the initial visit, we document that too. Everything is explained upfront before we proceed with permanent repairs, no hidden extras, no surprises.
Are you insured to fix chimney flashing?
Yes, we carry full public liability insurance for all roofing work, including chimney flashing repairs, leadwork, and re-pointing. This protects your property while we work at height. Repairs to fix chimney flashing often require ladders, scaffolding, or roof access, and we follow proper health and safety procedures on every job. You can ask to see our insurance documentation at any time. We take safety and professionalism seriously, whether it’s a quick patch repair or a full flashing renewal.
Can you attend urgently if water is coming in around the chimney?
Yes, we offer emergency call-outs for urgent chimney leaks across Dublin. If water is actively coming in around your chimney, especially near electrics or causing ceiling damage, searching chimney repair near me for a fast response makes sense, so call us directly and we’ll aim to attend as quickly as possible, often on the same day. Where we can, we’ll apply a temporary make-safe repair to stop the leak and prevent further damage while we prepare a quote for the permanent fix. For less urgent leaks (such as old stains or minor damp), we can usually attend within 24–48 hours. See our emergency roof repairs page for more details.
Can chimney leaks look like roof leaks elsewhere?
Yes, absolutely. Water can travel along roof timbers, down walls, and appear far from the actual entry point. A leak that shows up on your ceiling near the chimney might actually be coming from a slipped slate, a damaged valley, or even a blocked gutter metres away. That’s why we don’t assume the chimney is always the culprit, we trace the water path properly before diagnosing the issue. If the leak isn’t chimney-related, we’ll be honest about it and explain what the real source is. We’d rather fix the right problem than carry out unnecessary flashing work.
Do you repair surrounding tiles or slates as part of chimney work?
Yes, if tiles or slates around the chimney are damaged, slipped, or contributing to the leak, we can repair those as part of the job. Chimney leaks are sometimes caused by a combination of issues, faulty flashing plus a few missing tiles, for example. We take a holistic approach: when we’re on the roof to fix chimney flashing, we’ll also check the surrounding tiles, ridge details, and drainage to ensure the entire area is watertight. If additional work is needed, we’ll explain it and provide a clear quote before proceeding.
Do you work on domestic and commercial properties?
Yes, we carry out chimney flashing and repair work on both domestic and commercial properties across Dublin. If you’re looking for chimney repair near me for your home, our domestic work covers everything from terraced houses to large period properties with multiple chimney stacks. Commercial work includes offices, apartment blocks, schools, and other buildings where chimney leaks are affecting internal spaces or tenants.
