Clondalkin is one of West Dublin's most established residential areas — a historic village core surrounded by large housing developments built primarily through the 1970s, 1980s, and 1990s across estates like Rowlagh, Neilstown, Quarryvale, Bawnogue, Deansrath, and Cappaghmore. That build era defines the majority of roofing problems we encounter here.
The 1970s and 1980s housing stock is the dominant call across Clondalkin. Concrete interlocking tile roofs on these properties are now 40 to 50 years old — and the original felt underlay on roofs of this age is well past its designed lifespan. When felt fails beneath tiles that still look sound from the ground, recurring damp patches appear on upper ceilings that no amount of tile replacement will fix. The correct response is a strip and re-roof, not more patching. We carry out a significant number of full re-roof jobs across Clondalkin's older estate stock every year for exactly this reason.
Flat-roofed rear extensions are near-universal across Clondalkin's semi-detached and terraced properties. Original felt on 1980s and 1990s extensions is comprehensively at end of life — blistering, splitting, and leaking into extension ceilings and rear walls. We replace these with GRP fibreglass or EPDM rubber, both far more durable than the felt systems coming off.
Chimney stacks across Clondalkin's older properties consistently show deteriorated mortar, cracked flaunching, and failing lead flashing — particularly on west and north-facing stacks taking the worst of the prevailing weather. Chimney leaks are among the most frequently misdiagnosed problems in this area.
Commercial properties along the Nangor Road, Park West, and Clondalkin industrial areas generate a steady volume of flat roof repairs and replacements — a service we provide alongside our residential work across Dublin 22.

Not sure if we cover your area? Call us — we almost certainly do.
On newer properties, leaks almost always originate at the flashing rather than the roof covering itself — around chimneys, Velux windows, or at the junction between a flat roof extension and the main roof. These are installation-related failures rather than material failures, and they're repairable without replacing the roof covering. Sean will identify the exact source at inspection before anything is quoted.
The clearest signs are recurring damp in the same areas despite repeated repairs, slates or tiles slipping across the whole roof face rather than in isolated spots, and a roof over 40 years old with multiple repair rounds behind it. On Clondalkin's 1970s and 1980s estate stock specifically, felt failure is the most common driver — and once the underlay has gone, repair is no longer a sustainable answer.
Yes — we work on commercial flat and pitched roofs across the Park West industrial and business park area and along the Nangor Road corridor as part of our Dublin 22 coverage.
Active leaks during or after heavy rainfall — particularly from flat-roofed rear extensions where the felt membrane has finally failed, and from chimney stacks where flashing or flaunching has deteriorated. Both are common across Clondalkin's older housing stock and both can be made temporarily watertight quickly while permanent repairs are scheduled.
Never. Inspections and quotes are completely free with no obligation to proceed.
Yes — we source matching material on all repair work. On fibre cement slate, which is common across Clondalkin's 1980s and 1990s stock, we carry a range of profiles. Where a profile has been discontinued, we'll advise on the closest available match before the work starts.
