Roof Repair Cork,
Limerick, Galway
& Dublin.

Pitched roof repairs on Irish homes divide into a consistent set of recurring problems: slipped slates where fixing nails have corroded, broken concrete tiles where a branch or ladder impact has caused a fracture, open valleys where lead or mortar has failed and water is tracking along the internal junction, and ridge and verge mortar failures where the bedding has cracked and ridges are rocking in wind. Across Cork, Limerick, Galway and Dublin, these are the most common repair callouts we respond to — and in most cases, the repair can be completed on the first visit because our teams carry matching slate and tile stock on every van.

Slate replacement involves removing the damaged slate, cutting a new fixing clip, and sliding the replacement into position without disturbing neighbouring slates. Tile replacement is straightforward on interlocking profiles and slightly more involved on plain or traditional tiles where the mortar haunching at verge and hip needs matching. Valley repairs depend on condition — open valleys with leadwork failures receive new Code 4 lead, closed valleys with mortar failures receive Code 4 lead with correct stepped flashing. All repair work is documented with before-and-after photography and covered by our 10-year written workmanship guarantee on the repaired area.

Flat roof repairs on extensions, garages and dormers across Ireland most commonly involve blistered or split modified bitumen felt, failed seams on single-ply EPDM membranes, cracked or delaminated GRP fibreglass surfaces, and blocked or inadequate drainage outlets causing water to pond. The first step on any flat roof repair visit is a condition assessment — not just the visible defect, but the state of the surrounding membrane and the deck beneath it. A repair that addresses only the visible split while missing the saturated insulation and rotten boarding beneath it is a short-term fix that will fail within 12–24 months.

EPDM repairs on Firestone systems are completed using Firestone-compatible adhesives, seam tape and patch material — not generic sealants. Felt repairs use compatible SBS-modified material, torch-applied to ensure full adhesion. GRP repairs require specialist lamination techniques and correct resin matching. Where the damage assessment reveals that the overall membrane is at end of life, we will always recommend full replacement over a patch repair that is likely to fail elsewhere within a short period. We do not patch roofs that need replacing; that is not in the property owner's interest and it is not how we work.

Lead flashing failures at chimneys, abutments, dormers and valleys are the single most common source of persistent, hard-to-trace roof leaks across Irish properties. Water entering at a failed flashing can travel several metres along rafters and sarking before it drops to a ceiling — so the water stain inside the property is frequently not directly below the failure point. Identifying the actual entry point requires a systematic inspection of all flashing details on the affected elevation, not just a visual check from ground level. Our repair teams access every flashing element with ladders or scaffolding and inspect by hand.

Lead flashing repairs range from re-dressing lifted lead at chimney abutments (the most common single repair across Cork and Limerick properties), to replacing failed step flashings at dormer walls, to installing new soakers and cover flashings where the original lead has reached the end of its service life. All replacement lead is Code 4 as a minimum, Code 5 at chimneys and wide abutments — the same specification as a new installation. Lead is dressed by hand to the profile of the tile or slate course below. Chimney repairs also include repointing of masonry where required, and lead cap or mortar haunching replacement at the flue. Full 10-year workmanship guarantee on all flashing and chimney repair work.

Storm damage roof repairs across Cork, Limerick, Galway and Dublin follow a consistent pattern after Atlantic weather events: mortar-bedded ridge and hip tiles are the first elements to fail, lifted by wind uplift once the bedding mortar cracks; then verge tiles and slates on exposed elevations; then isolated slates where fixing nails have corroded and the slate was being held by friction alone. After every named storm, our teams are mobilised across all five regions and can be on-site within 4 hours in Cork and Limerick, 6 hours in Galway and Dublin. Emergency weatherproofing is completed on arrival; the permanent repair is scheduled as priority within 3–7 days.

Storm damage repair documentation for insurance claims is a standard part of every emergency callout. Our written damage report identifies every element of storm-attributable damage separately from pre-existing wear or maintenance issues — the distinction your insurer requires before approving a claim. The report includes photographs of the damage, the cause-of-damage assessment, the specification for permanent reinstatement, and an itemised cost. We have worked alongside loss adjusters from all major Irish home insurers and our reports are accepted without additional survey visits in the large majority of claims.

The single most cost-effective roof maintenance upgrade available on Irish homes built before 2010 is the conversion from mortar-bedded ridge and verge systems to mechanical dry-fix systems. Mortar-bedded ridges and verges require re-pointing every 10–15 years as the mortar cracks under thermal movement and wind vibration. In the meantime, loose ridge tiles in storms become a safety hazard and a source of water ingress. Dry-fix mechanical ridge systems — polypropylene or aluminium profiles with batten-fixed roll ventilation — eliminate the maintenance cycle permanently and are more wind-resistant than mortar at the BS 5534 wind uplift ratings that apply in exposed Irish locations.

Dry ridge and dry verge repair or conversion is typically a 1–2 day job on a standard 3-bed semi. The old ridge and verge tiles are removed, the mortar bedding is cleared, the dry-fix profiles are fitted to the battens, and the ridge/verge tiles are re-laid mechanically. No scaffold is required on most single-storey elevations — ladders and access boards are sufficient. The finished result looks identical to the original, performs better in wind, and requires no maintenance for the life of the roof. On any home in Cork, Limerick, Galway or Dublin where the ridge has been repaired twice or more with mortar, conversion to dry-fix is our standard recommendation.

Structural timber repairs — rafter, purlin, ridge board and fascia replacement — are identified at inspection on a significant proportion of repair callouts on older Irish properties. The entry point is usually water tracking from a failed flashing or slipped slate; once we are in the attic space we assess what the water has done to the timber below. Rotten or compromised rafters are a structural issue that must be addressed before the repair above is completed — fitting new slates over a rotten rafter leaves a hidden failure that will return within a few years and potentially cause a section of covering to lose fixing support.

Timber replacement is carried out with treated softwood to BS 5268, sized to match the existing specification or upgraded where required. On properties in Cork, Limerick and Galway where the original timber is undersized for current wind loading standards, we recommend upgrading to current sizing as part of the repair. All structural timber repairs are photographically documented before the new covering goes on, producing a permanent record of the condition of the structure at the time of the repair. Where the extent of structural damage requires a structural engineering assessment — typically where more than three rafters in a section are affected — we arrange this as part of the project programme.
