Blanchardstown and Dublin 15 grew rapidly from the 1980s onward — one of the largest planned expansions of Dublin's suburban footprint. Estates like Corduff, Mulhuddart, Castaheany, Hartstown, Huntstown, and Ladyswell were built predominantly through the 1980s and 1990s. More recent phases in Tyrrelstown and Hansfield have added newer stock on top.
The 1980s and 1990s estate housing is the most common call across Dublin 15. Concrete interlocking tile roofs on these properties are now 30 to 45 years old. The original felt underlay is at or near the end of its designed life — and when felt fails, tiles that look perfectly sound above it no longer keep the water out. Recurring damp on upper ceilings in this age bracket is felt failure far more often than tile damage. The fix is a strip and re-roof, not tile replacement.
Flat-roofed rear extensions are standard across Blanchardstown's semi-detached housing. The felt on 1980s and 1990s extensions is comprehensively past its life — blistering, splitting, and leaking into extension ceilings. We replace these with GRP fibreglass or EPDM rubber, both significantly more durable than what's coming off.
Newer properties in Tyrrelstown and Hansfield — built from the 2000s onward — generally have sounder roof structures but frequently show flashing failures and roofline detail issues that weren't correctly finished on the original build, particularly around Velux windows and chimney junctions.

No jargon. No hard sell. Just a clear process from your first call to a weatherproof roof.

Not sure if we cover your area? Call us — we almost certainly do.
On Blanchardstown properties built in the 1980s and 1990s, this is almost always felt failure beneath intact-looking tiles. Replacing the tiles won't fix a failed underlay — the roof needs to be properly stripped and re-laid on new felt and battens. Sean will confirm this at inspection and give you a written quote for the correct fix.
It depends entirely on what's needed. A single slate or tile replacement is a minor repair. A flat roof replacement on a rear extension is a larger job. We always inspect first and provide a full written quote — so you have a firm price before any work starts, not an estimate that changes on the day.
Yes — 24/7 for genuine emergencies. If you have an active leak, storm damage, or a fallen chimney pot creating an open roof, call us immediately. We cover all of Dublin 15 and prioritise same-day response where possible.
Yes. We carry out a significant amount of work on the newer Dublin 15 developments — primarily flashing repairs, Velux leaks, and roofline details that weren't correctly finished on the original build.
