What Is RoofCostIreland.com?

RoofCostIreland.com is an independent roof cost calculator and information resource built specifically for homeowners in the Republic of Ireland. We provide free, instant estimates for roof replacement across all four major Irish roofing materials — concrete tiles, natural slate, EPDM flat roofing and standing seam metal — adjusted for your specific county and roof specification.

Unlike comparison sites that require you to hand over your contact details before showing any results, our calculator delivers a full cost breakdown immediately — including materials, labour, scaffolding, disposal and VAT at 13.5% — so you can understand the market before engaging any contractor.

We also publish comprehensive guides on roofing costs by county, how to choose a trustworthy roofer, when to repair versus replace, and how to access SEAI grants for insulation upgrades alongside reroofing work.

How We Calculate Estimates

📐

Roof Area × Material Rate

We apply current 2026 Irish material supply costs (per m²) and installation labour rates to your specified roof area. Material costs are updated based on supplier price indices and contractor feedback.

📍

County Labour Adjustment

We apply a county-specific labour modifier based on regional contractor rate data. Dublin runs +18% above the national average; rural Connacht and Ulster counties run 5–7% below. This modifier is applied to the labour component of your estimate only.

🏗️

Complexity Multiplier

A simple single-pitch roof is faster and cheaper to reclad than a complex hip roof with dormers and valleys. We apply a complexity multiplier (0.9× to 1.3×) based on your selected roof type to reflect this.

🧾

VAT at 13.5%

All estimates include VAT at the Irish reduced construction rate of 13.5%. This is applied to the combined materials and labour subtotal and shown as a separate line item, as it would appear on a legitimate contractor invoice.

What Our Estimates Include

Every estimate from our calculator includes: materials (tiles, slate, EPDM or metal at the selected grade), installation labour, scaffolding hire, removal and disposal of the existing roof covering, and VAT at 13.5%.

What Our Estimates Do Not Include

Our estimates are based on standard roof replacement scope. They do not include structural timber repairs (rafters, battens), fascia and soffit replacement, gutter replacement, chimney repointing or removal, attic insulation upgrades, or any other work outside the roof covering itself. These items are typically quoted separately by Irish contractors once the old roof covering is stripped back and the underlying condition assessed.

⚠️ Important Disclaimer

All estimates provided by RoofCostIreland.com are indicative only. They are based on national average Irish contractor rates for 2026 and are intended to provide a general market benchmark — not a firm quotation. Actual costs for your specific project will depend on the condition of your roof structure, site access, the specific materials selected by your contractor, and local labour supply and demand at the time of your project. Always obtain a minimum of three written quotes from qualified, VAT-registered Irish roofing contractors before committing to any work. RoofCostIreland.com accepts no liability for decisions made in reliance on the estimates provided by this tool.
