New Roof Installation
Cork, Limerick,
Galway & Dublin.

For pitched roof installations across Cork, Limerick, Galway and Dublin, we specify Tegral T2-S fibre-cement slates for coastal and exposed locations (West Cork, the Galway coast, Dublin Bay), Marley Edgemere or Ludlow Plus concrete tiles for inland residential properties, and natural Welsh or Spanish slate for heritage and period buildings. The choice of covering is not arbitrary — T2-S rated slates are wind-rated for severe exposure zones and carry a 30-year guarantee, whereas standard concrete tiles in the same coastal location show accelerated weathering within 10–15 years. We specify to location, not to price.

Every pitched installation includes new breathable roofing membrane to BS 5534, counter-battening, tiling battens, and Code 4 or Code 5 lead flashings at all junctions. Mechanical dry-fix ridge and dry-verge systems are standard on every installation — we do not use mortar-bedded ridges. Mortar-bedded ridges on older Cork and Limerick homes are the single most common source of storm damage we attend to; converting to dry-fix at re-roof stage eliminates that problem permanently. The structural assessment at survey stage covers rafters, purlins, ridge boards, fascia boards and ventilation — all remediation is priced before work begins.

Flat roof installations on extensions, dormers, garages and commercial structures across Ireland require a fundamentally different approach to pitched roofs. The primary failure mode for flat roofs is water finding its way through internal joints in the membrane — a problem that Firestone EPDM, installed as a single sheet spanning the full roof area, eliminates by design. We are Firestone Approved Installers, a condition of the 20-year material warranty. For trafficable flat roofs — balconies, bay tops, roof terraces — GRP fibreglass is specified, which is rigid, seamless and fully trafficable once cured.

All flat roof installations are built with correct drainage falls (minimum 1:80 gradient), rigid PIR insulation to TGD Part L 2022 standard, upstands at all abutments, and drip edge perimeter trims. We inspect and repair existing decks before laying any new membrane — if the deck is rotten or wet, it is replaced before the membrane goes down. We do not waterproof over a failed substrate and leave a hidden problem for a future owner to discover. This approach costs more upfront; it is the only approach that produces a roof that performs for its rated lifespan across Cork, Limerick, Galway and Dublin.

Victorian terraces, Georgian townhouses, Edwardian semis and pre-1900 cottages across Cork city, Limerick city, Dublin and the historic towns of Munster and Leinster require a different approach to new roof installation than modern properties. The materials are different — natural Welsh or Bangor Blue slate, hydraulic lime mortar, Code 5 lead flashings, timber sarking boards — and in properties within ACA designations or on the protected structures register, local authority planning requirements add a further constraint that non-specialist contractors regularly fail to navigate correctly. We know these roofs and we know these planning requirements.

For heritage re-roofing, we source reclaimed and matching natural slate to minimise the visual impact of new material on partial and full re-roofs. All ridges, verges and valleys on ACA or protected structure properties are completed with hydraulic lime mortar (NHL 3.5 or 5 as appropriate) rather than OPC cement, which is too rigid for traditional masonry and causes cracking and re-repointing within 5–10 years. Full planning compliance documentation, photographic records and material certification are provided on completion. We work alongside conservation architects and local authority heritage officers in Cork, Limerick and Dublin where required.

New commercial roof installations across Cork, Limerick, Galway and Dublin include the full range of flat commercial systems — Firestone EPDM, Firestone UltraPly TPO, Sika Sarnafil single-ply PVC, composite insulated panels and standing seam metal — as well as pitched natural slate and tile re-roofing for institutional and public-sector buildings. We carry full PSCS capability on all commercial projects, producing safety plans, method statements and risk assessments as standard. All commercial installations are covered by our 10-year written workmanship guarantee, in addition to manufacturer warranties.

Commercial clients in Cork, Limerick and Galway include retail units, warehouses, office buildings, schools, civic offices and healthcare facilities. For institutional clients, documentation is provided in public procurement format — NBS-compliant specifications, structured BQ, tax clearance, material certifications and as-built drawings. Project management on site is always by a dedicated Recommended Roofing foreman; we do not subcontract commercial projects. The same quality standard, the same materials and the same 10-year guarantee applies on a 50m² garage extension as on a 5,000m² industrial re-roof.

Dormer extensions and attic conversions create new roof structures that must match the main house specification in both materials and performance. For pitched dormers across Cork, Dublin and Limerick, we use matching tile or slate to the existing roof — sourced to match as closely as possible for period properties. The dormer cheeks, rear flat roof, and the junction between the dormer and the main roof slope are all flashed with Code 4 or Code 5 lead, formed by hand on-site. This junction is where poorly designed and installed dormers fail — typically within 5–7 years of construction.

Flat-roofed dormers use Firestone EPDM as standard — the same single-ply system used on larger flat roofs, sized to the dormer area and including all upstands, drip edges and the window flashing detail. Velux and Fakro window installations are included and coordinated with our structural and carpentry teams. All dormer and attic conversion roofing is insulated to TGD Part L 2022 standard as a matter of course. We work fully coordinated with the structural engineer, the attic conversion contractor and the planning consultant — no separate interface meetings required from the homeowner.

Structural timber replacement is identified at survey stage on the majority of full re-roof projects across Cork, Limerick and Galway, particularly on homes built before 1980 where galvanised nail fixings have corroded and untreated timbers have been exposed to moisture ingress over decades. The most common items requiring replacement are ridge boards, individual rafters, sections of purlin and fascia boards. We price all timber work before the project begins — no mid-job surprises about additional costs when the felt is stripped back and the deck is exposed.

Replacement timber is treated softwood to BS 5268, sized to match the existing specification or upgraded where the original size is undersized for current wind loading requirements. On projects where the extent of structural damage is greater than anticipated at survey, or where structural calculations are required for insurance or planning purposes, we arrange a structural engineering assessment. All timber replacements are documented with before-and-after photography as part of the project file. The 10-year written workmanship guarantee covers all structural timber replacement work alongside the new roof covering.

A full re-roof is the point at which every underlying fault is finally put right rather than patched. The strip-off routinely exposes cracked or broken tiles and slipped or missing slates that were being held by friction, failed flashing and ridge mortar failure at the chimney and hips, and felt underlay deterioration where the original bitumen felt has gone brittle and porous. Where a long-running roof leak has been tracking into the structure, we carry out the roof leak repair at source and assess the timber for structural rafter damage before the new covering is laid — new slates over a soft rafter simply hide the failure.

Poor ventilation / condensation is the hidden fault we correct most often on 1970s–2000s homes: without a clear airflow path from eaves to ridge, warm moist air condenses on the cold underside of the deck and rots the timber from within. We build in a continuous ventilation path with eaves vents, roof vent / tile vent units and a breathable membrane. Roofline / fascia damage — rotten fascia and soffit behind failed gutters — is renewed as part of the same programme so the new roof sits on sound, dry timber. Everything found at survey is priced before work begins.

A new roof is not just a covering — domestic roof construction is decided at the junctions. Every chimney and abutment is re-flashed in Code 4 or Code 5 lead, dressed by hand to the course below. Every skylight and rooflight gets a new flashing kit and a correctly formed upstand, because that opening is the single detail most often rushed on the original build and the one we are called back to most.

The roofline is renewed at the same time: fascia and soffit onto sound timber, a new rain gutter run hung to the correct fall, and outlets and downpipes sized for the roof area above them. Doing the roofline while the scaffold is already up costs a fraction of returning to it in three years. Weatherproofing is only ever as good as its worst detail — so we specify and photograph every one of them, and the whole lot is covered by the same 10-year written guarantee.
