Re-Roofing a House in Galway
Full Replacement Process, Timeline & 2026 Costs
Full Replacement Process, Timeline & 2026 Costs
A full re-roof on a standard 3-bed semi in Galway typically takes 5–8 working days and costs €9,500–€18,000 (indicative 2026 pricing) depending on pitch, materials and access. The job means stripping the roof back to the rafters, upgrading felt, battens and insulation, then re-covering with new slates or tiles, lead flashings and code-compliant ventilation.

That's the short answer. Below is the detail — the process step by step, the materials that actually stand up to Atlantic weather, and honest cost ranges for the homes we re-roof around Galway City, Salthill, Oranmore, Barna and Knocknacarra.
Not every leaking roof needs replacing. But if you're seeing three or more of the following, patch repairs are usually throwing good money after bad:
Galway's coastal climate accelerates all of this. The Met Éireann Athenry station records around 1,200mm of annual rainfall and gusts regularly over 100 km/h on exposed coastal stretches from Salthill through Spiddal. Roofs here work harder than roofs in the midlands, and they show wear sooner.
If you're weighing repair against replacement, our Galway roof renovation page covers the middle ground — targeted upgrades that extend a roof's life by 10–15 years without a full strip.
Here's what actually happens on site when we re-roof a house in Galway. This is the sequence we follow on every job, from a bungalow in Renmore to a two-storey semi in Doughiska.
We inspect the roof externally and from inside the attic. We measure pitch, note rafter condition, check for existing insulation, and assess access for scaffolding. You get a written fixed-price quote — no day-rate surprises. For a rough ballpark before we visit, the roofing cost calculator gives an indicative figure in about a minute.
A full scaffold goes up on the elevations we're working. On tight terraces near the Claddagh or on Father Griffin Road we sometimes need a permit from Galway City Council for footpath scaffolding — we handle that paperwork. A skip is positioned, and we sheet the ground and any nearby plants.
Old slates or tiles come off in sections, working from ridge to eaves. Anything reusable (natural slate in sound condition, ridge tiles, lead) is set aside. The rest goes to the skip for sorting and recycling. Rafters, wall plates and purlins are inspected as we go — any rotten or split timber is flagged for replacement before we cover back up.
Damaged rafters are sistered or replaced. We fit a breathable roofing membrane — typically Klober Permo Air or similar — that lets moisture escape from the attic while blocking wind-driven rain. In Galway this matters. Non-breathable felt causes condensation, and condensation causes the exact rot we're trying to fix.
Treated softwood battens are fixed to a strict gauge set by the slate or tile size — usually 100mm gauge for standard slate. Battens are stainless-steel nailed on coastal jobs; galvanised nails corrode within a decade within a few kilometres of the sea.
Slates or tiles go on from eaves to ridge, double-nailed on all exposed elevations. We use copper or stainless-steel nails as standard on Galway jobs — never plain steel. Ridge tiles are mechanically fixed (Ireland's wind uplift regulations effectively ended traditional mortar-only bedding for new work).
New code 5 lead flashings to chimneys, abutments and step-flashings. GRP or lead-lined valleys. Fresh eaves ventilation and ridge ventilation to meet current Part L / Part F requirements. Any Velux or roof-window flashing kits are renewed at this stage.
We usually recommend renewing fascias, soffits and gutters at the same time — the scaffold's already up, the cost per metre is a fraction of a separate call-out, and old cast-iron or timber components rarely outlast a new roof. Final clean-down, magnet sweep of the garden for nails, and a walk-around with you before scaffold comes down.
Material choice matters more here than almost anywhere in Ireland. Salt spray, wind uplift, and driven rain rule out several options that work fine inland.
| Material | Indicative Cost (supply + fit) | Lifespan | Best For |
|---|---|---|---|
| Natural Spanish slate (Cupa H12) | €95–€130/m² | 80–100+ years | Period homes, Salthill, Knocknacarra seafront properties |
| Fibre-cement slate (Tegral Thrutone) | €65–€85/m² | 50–60 years | Standard semis, budget-conscious full re-roofs |
| Concrete tile (Redland Cambrian) | €60–€80/m² | 50+ years | Newer estates in Doughiska, Ballybane, Oranmore |
| Clay tile | €90–€120/m² | 80+ years | Character properties, planning-sensitive areas |

For coastal properties within 2km of the shore, we push clients toward natural slate with stainless fixings. It costs more up front but it's the only combination that reliably lasts the design life without expensive mid-life repairs.
A re-roof is the once-in-a-generation chance to sort insulation properly. Under current Irish building regulations, any significant roof works should bring insulation up to a U-value of 0.16 W/m²K where practical. That usually means 300mm of mineral wool at ceiling level, or 150mm PIR between rafters plus 50mm below for a warm roof.
Homes upgrading roof insulation as part of wider works may qualify for SEAI Better Energy Home grants — currently up to €1,700 for attic insulation depending on measure and property type. Worth checking before the scaffold goes up.
Ventilation is the other half of the equation. We fit continuous eaves vents and either ridge vents or tile vents at a rate calculated for the roof area. Skip this and you'll be back inside five years chasing condensation stains.
Every job is different, but here's what real Galway re-roofs cost in current market conditions:
Add roughly €800–€2,500 for full fascia, soffit and gutter renewal at the same time. Add €400–€900 per chimney for lead flashing renewal. Scaffold on a tight site or a three-storey elevation can add €600–€1,500.
These are honest current ranges — the final figure depends on pitch, access, material choice and timber condition once we strip back. Every quote we issue is fixed-price, so what you sign is what you pay.
Weather is the wildcard. A standard 3-bed semi should be a 5–8 working day job in dry conditions. Add 2–3 days for genuine autumn or winter weather — we won't open a roof if the forecast is unworkable, and no honest Galway roofer will. Booking in April–September gives you the best run at continuous dry days.
We give every Galway client a written schedule with start date, expected finish, and a weather-contingency plan. You'll know which day is strip day (the noisy one) and which day the scaffold comes down.
We've re-roofed homes from Barna out to Oranmore, through the estates in Knocknacarra, the older stock around Bohermore and Woodquay, and the coastal properties along the Salthill promenade. Each area has its own quirks — planning constraints in the Claddagh conservation zone, wind exposure ratings that change street by street in Salthill, and the mix of 1970s concrete-tile estates in Doughiska that need a specific tile-nail combination.

If you're planning a re-roof anywhere in Galway City or the county, book a survey with our Galway roofing team for a free, no-obligation fixed-price quote. We'll walk the roof, check the attic, and give you an honest recommendation — repair, renovation or full re-roof — with the numbers to back it up. Call 091 622895 or request a callback online.
A standard 3-bed semi takes 5–8 working days in dry weather. Larger or more complex roofs (dormers, hips, valleys) run 8–12 days. Winter weather can add 2–3 days of standby time — we don't open a roof when heavy rain or high winds are forecast.
No, not for a like-for-like re-roof. If you're changing the material significantly (e.g. slate to tile), altering the roof profile, adding dormers, or the property is in a conservation area like the Claddagh, you'll need to check with Galway City or County Council first.
Natural slate with copper or stainless-steel fixings. Fibre-cement slate is a solid budget alternative for properties more than 2km inland. Avoid galvanised nails and non-marine-grade fixings within sight of the sea — they corrode within 10–15 years.
Yes, in almost all cases. It's noisy during the strip (days 1–2) and there will be scaffold across windows for the duration, but the house stays weather-tight overnight. We tarp any open sections before the crew leaves each evening.
There's no direct grant for the roof covering itself. But if you upgrade attic or rafter insulation during the works, you may qualify for SEAI Better Energy Home grants — up to €1,700 for attic insulation at 2026 rates. We can point you toward the correct application route.
If less than 15% of slates are damaged, underlay is sound, and timbers are dry, targeted repairs make sense. If you're seeing widespread nail sickness, sagging, failed underlay or damp in multiple rooms, a full re-roof is the economically sensible route. A survey will give you a definitive answer.
