Chimney Installation & Chimney Work
Chimney installation and chimney work — including repairs, repointing and flashing — across Kilkenny, Laois, Carlow, Waterford & South Tipperary.
Chimney Installation & Chimney Work
A chimney is one of the most exposed parts of a roof — it takes weather from every direction, and the junction where it meets the roof covering is a common place for water to find its way in if it isn’t properly detailed. Peak Performance Roofing carries out chimney installation and chimney work across Kilkenny, Laois, Carlow, Waterford and South Tipperary, including chimney repairs, repointing and flashing.
We treat a chimney as part of the wider roof, not a job on its own — so the surrounding tiles, flashing and roof junction are checked and integrated properly at the same time as the chimney itself.
Signs You May Need Chimney Work
- Crumbling, cracked or visibly worn mortar joints on the chimney stack
- Damp patches or staining on a ceiling or wall near the chimney breast
- Daylight or damp visible around the chimney from inside the attic
- Flashing around the base of the chimney that looks lifted, cracked or corroded
- Staining or streaking down the chimney stack itself after rain
What Causes Chimney Deterioration
Because a chimney stands proud of the roofline, it takes more direct weather exposure than almost any other part of the roof. Mortar joints weather and crack over time, particularly through repeated freeze-thaw cycles in winter, and flashing materials can loosen, corrode or come away from the chimney with age. Left unaddressed, this kind of wear is one of the more common causes of water ingress at roof level.
The Chimney Junction Is a Common Leak Point
Because a chimney passes straight through the roof covering, the junction between the chimney and the roof relies entirely on sound mortar and properly fitted flashing to stay watertight. If either has failed, water can track down into the roof structure or the chimney breast well before it becomes obvious inside the house. If you notice any of the signs above, it’s worth calling 085 249 7521 to have it looked at.
Chimney Flashing & Weatherproofing
Flashing is what actually seals the join between a chimney and the surrounding roof tiles, and it’s one of the most common sources of a leak around a chimney — often before the chimney stack itself shows any obvious damage. We check flashing as part of any chimney work, and repair, renew or fit it as needed so the junction between the chimney and the roof stays weathertight.
How We Approach Chimney Work
Our general approach to chimney installation and chimney work is the same as the rest of our roofing work:
- Inspect the chimney and the surrounding roof junction — looking at mortar condition, flashing, and the tiles immediately around the chimney.
- Identify the actual cause — whether that’s failed pointing, damaged flashing, or general weathering.
- Carry out the work — chimney installation, repairs, repointing or flashing, integrated properly with the surrounding roof covering.
- Leave the area tidy — the work area and any debris are cleared once the job is complete.
