Ireland's Most Accurate
Roof Cost Calculator
2026

A new roof in Ireland typically costs between €4,500 and €25,000 depending on roof size, material type and location. Concrete tile roofs start from around €4,500 for a standard semi-detached, while natural slate roofs on larger detached properties can reach €20,000 or more. However, costs in Dublin and surrounding counties tend to run 15–20% higher than rural areas due to labour demand. Use the calculator above to get a county-specific estimate with a full VAT breakdown instantly.

Concrete roof tiles are the most affordable roofing option for Irish homeowners, with material costs of €15–€30 per square metre. A standard 80m² semi-detached roof costs €4,500–€7,500 all-in including labour, scaffolding and VAT at 13.5%. However, concrete tiles have a lifespan of 30–50 years versus 80–100 years for natural slate, making them potentially less cost-effective over the full life of the home. For most budget-conscious Irish homeowners, high-quality interlocking concrete tiles offer the best balance of upfront cost and durability.

Yes, roofing work in Ireland is subject to VAT at 13.5% — the reduced rate applied to construction services on residential properties. This applies to both materials and labour when supplied together by a VAT-registered contractor. However, if you purchase materials separately from a supplier and hire labour independently, VAT rates may differ between the two invoices. All estimates on RoofCostIreland.com display the 13.5% VAT as a separate line item so you see the full cost before requesting quotes.

SEAI grants do not cover roof covering replacement directly, but they do cover insulation upgrades commonly done alongside reroofing. The SEAI Better Energy Homes scheme offers €800–€2,400 for attic and roof insulation when installed by an SEAI-registered contractor. However, the roof covering itself — tiles, slate or felt — is not grant-eligible under current 2026 SEAI schemes. Homeowners should ask their roofer about combining insulation with the reroofing job to maximise available grant funding.

Natural slate is widely considered the best roofing material for Ireland's wet Atlantic climate, offering an 80–100 year lifespan and exceptional resistance to driving rain, wind and frost. Irish and Spanish slate perform well due to their high density and low water absorption. However, natural slate costs 2–3 times more per square metre than concrete tiles and requires a skilled slater for installation. For homeowners prioritising long-term value, natural slate offers the lowest lifetime cost-per-year of any mainstream Irish roofing material.

Planning permission is not required for a like-for-like roof replacement on a standard residential property in Ireland under exempted development rules. You can replace your existing roof with the same or similar material without applying to your local council. However, if your home is a protected structure, in an Architectural Conservation Area, or you are significantly changing the roof material or adding roof lights, planning permission may be required. Always confirm with your local authority before starting work to avoid enforcement issues later.
