Shannon is one of Ireland's most distinctive towns — a planned settlement built almost entirely in a single concentrated era from the 1960s through to the 1980s to support Shannon Airport and what became one of Ireland's first and most successful export processing zones. That single-era build history creates a roofing and chimney maintenance situation that is unlike almost any other town in Clare or the wider Midwest — and understanding it is the first step towards making the right decisions about your Shannon property's chimney.
At Doherty Roofing, we carry out professional chimney repairs for homeowners across Shannon and the surrounding area. From repointing deteriorating mortar joints and repairing failed lead flashing to replacing damaged chimney pots and carrying out full chimney stack rebuilds, Jim and the team diagnose chimney problems accurately and deliver lasting repairs using materials appropriate for Shannon's specific climate and housing stock.
Based in Limerick — just 25 kilometres from Shannon — we are fully insured, Safe Pass certified and members of the National Guild of Master Craftsmen. Free quotes, no call-out fees, no pressure to proceed.
If you own a property in Shannon that was built between the 1960s and the 1980s — which covers the vast majority of the town's residential housing stock — your chimney stack is now between forty and sixty years old. This is the age at which chimney problems become not just possible but probable on properties that have not had regular professional inspection and maintenance.
Here is what happens to a chimney stack over forty to sixty years in Shannon's estuary-adjacent climate:
The mortar joints between the chimney bricks erode progressively through Shannon's persistent moisture exposure and the freeze-thaw cycles of Clare winters. As mortar fails, water penetrates the masonry and the deterioration accelerates — each winter's frost expanding the moisture that has entered the cracked joints, progressively widening gaps and loosening bricks. The lead flashing at the base of the chimney stack — the seal between the chimney and the surrounding roof surface — has a typical serviceable life of around fifty years in normal conditions and may be at or approaching the end of that lifespan on the oldest Shannon properties. The flaunching — the mortar bed at the top of the stack holding the chimney pot in place — cracks and erodes under the combined effect of age, moisture and freeze-thaw stress, eventually destabilising the pot and creating a direct water entry point at the apex of the stack.
The honest message for Shannon homeowners is straightforward: if your chimney has not been professionally inspected in the past five to ten years, arranging a free inspection is one of the most worthwhile property maintenance steps you can take.
Storm damage to your chimney is covered under most standard home insurance policies in Ireland. If your Shannon chimney has sustained sudden storm damage, Doherty Roofing provides full written damage assessments, photographic documentation and itemised repair quotes to support your insurance claim. We are experienced in working with homeowners through the insurance claims process.
My Shannon house was built in the 1970s — should I have my chimney inspected?
Yes — absolutely. Properties built in this era in Shannon are now over fifty years old and their chimney stacks have been exposed to Shannon's estuary moisture and Clare's freeze-thaw winters throughout that entire period. Mortar deterioration, flashing failure and flaunching cracking are all realistic possibilities on chimneys of this age that have not been regularly inspected and maintained. A free inspection from Doherty Roofing will tell you exactly where your chimney stands and what if anything needs to be done.
My chimney has not been used in years since we switched to gas — does it still need maintenance?
Yes — and potentially more so than an actively used chimney. An unused chimney receives none of the drying benefit that regular fire use provides, making it more vulnerable to internal moisture build-up and progressive mortar deterioration. An unused chimney in Shannon's estuary climate that has been left open at the top for years without a cowl or cap may have deteriorated internally more than its external appearance suggests. We inspect unused chimneys across Shannon and advise honestly on what maintenance or protection is required.
Can a failing chimney cause damp inside my Shannon home?
Yes — and it is one of the most commonly misdiagnosed damp problems in Shannon. Water entering through deteriorated chimney mortar or failed flashing typically presents as damp patches on walls adjacent to the chimney breast — and is frequently misidentified as rising damp or condensation. Have the chimney inspected before spending money on internal damp treatment.
How much does chimney repointing cost in Shannon?
A straightforward repointing job on a standard domestic chimney stack accessible from the roof without scaffolding typically falls in the range of €350 to €600. Where scaffolding is required or the extent of deterioration is more advanced, costs run towards €600 to €900 or beyond. Doherty Roofing provides free, detailed written quotes so you will always know the full cost before work begins.
How quickly can you get to Shannon for a chimney repair?
Shannon is 25 kilometres from our Limerick base — a short, direct journey that allows us to respond quickly to both routine enquiries and urgent calls from the town. We will always give you an honest estimated arrival time when you call.

Yes. Doherty Roofing is fully insured with public liability cover, our team are Safe Pass certified and we are members of the National Guild of Master Craftsmen. We are happy to confirm all details on request.
Shannon Estuary Moisture Exposure
Shannon's position adjacent to the Shannon Estuary creates a specific moisture environment that inland Clare properties do not experience to the same degree. The estuary generates persistent airborne moisture that subjects the external surfaces of chimney stacks — their brickwork, their mortar joints and their lead flashings — to sustained dampness throughout the year. This moisture exposure accelerates the deterioration of mortar and masonry faster than equivalent properties in more sheltered inland positions. Properties on the western and southern sides of Shannon's residential estates — those facing the estuary — are particularly affected.
The Unused Flue Problem
Shannon's housing stock has undergone significant changes in heating systems since the estates were built. The vast majority of Shannon properties were originally constructed with open fireplaces and solid fuel heating systems — and their chimney stacks were designed and built to vent these systems. Over the decades, most Shannon homeowners switched to gas or oil central heating, leaving their original chimneys unused.
An unused chimney is not a maintenance-free chimney. Quite the opposite — without the regular warming effect of fire use that drives moisture out of the stack, unused chimneys are more vulnerable to moisture penetration, internal condensation and the progressive mortar deterioration that leads to water ingress. A chimney stack that has been cold and unused for twenty or thirty years while Shannon's estuary moisture has been working on its mortar joints may have deteriorated significantly — often invisibly from the outside until water begins to appear on an internal wall.
For unused chimneys, fitting an appropriate cowl or cap to seal the flue opening while maintaining adequate ventilation is a straightforward and cost-effective preventative measure. Doherty Roofing carries out this work across Shannon as part of our chimney maintenance service.
Shannon Airport Corridor Exposure
Properties on the northern and western edges of Shannon — particularly those in open positions near the airport corridor — experience elevated wind exposure compared to more sheltered central areas of the town. Chimney stacks in these exposed positions are subjected to more sustained wind pressure on their mortar joints and flashings, accelerating the physical weathering that leads to mortar erosion and flashing displacement.
