TL;DR
Quick summary for busy readers — key cost takeaways before you compare contractor quotes.
- Irish roofers charge between €60 and €160 per m² in 2026 depending on material.
- Concrete tile sits at €60–€90/m². Natural slate runs €110–€160/m². These figures include materials and labour but not scaffolding.
- To calculate your total, multiply your roof area by the per-m² rate, then add €800–€3,000 for scaffolding.
Why Does Cost per m² Matter?
It gives you a quick way to sanity-check any quote.
If a contractor quotes €18,000 for a 90 m² roof with concrete tile and the going rate is €75/m², that works out to €6,750 plus scaffolding. A quote of €18,000 should prompt questions.
Per-m² rates are not the full picture, but they are a useful starting point.

How to Measure Your Roof Area
You do not need to be on the roof to get a usable estimate.
Ground-level calculation method
- Measure the ground-floor footprint of your house (length × width)
- Multiply by a pitch factor based on your roof angle:
- Standard pitched roof (35 degrees): multiply by 1.4
- Shallower pitch (25 degrees): multiply by 1.2
- Steeper roof (45 degrees): multiply by 1.6
- Add 10% if your roof has dormers, a chimney valley or a hip
Worked examples
Terraced house: 5.5m × 8m = 44 m² footprint × 1.4 = 62 m² roof area At €75/m² (concrete tile) = €4,650 for materials and labour before scaffolding
Semi-detached: 7m × 9m = 63 m² × 1.4 = 88 m² At €75/m² = €6,600 before scaffolding
Detached 4-bed: 10m × 12m = 120 m² × 1.4 = 168 m² At €120/m² (natural slate) = €20,160 before scaffolding
These are ballparks. Your actual quote will vary based on the number of hips, chimney positions, roof access and condition.
How Does Labour Rate Affect the Per-m² Price?
The per-m² rates above are blended rates that include labour. But it is useful to understand what is inside them.
Material cost typically accounts for 40–50% of the rate. Labour accounts for the other 50–60%.
So on a €75/m² concrete tile job, roughly €35–€40 covers tiles, membrane, battens and fixings. The rest is the roofer's time.
Irish roofer day rates in 2026:
| Region | Rate per roofer per day |
|---|---|
| Dublin | €350–€450 |
| Cork | €320–€400 |
| Galway / Limerick | €290–€370 |
| Rural areas | €250–€330 |
A standard semi-D re-roof typically takes a crew of two to three roofers three to five days.
Why Do Quotes Vary So Much for the Same Roof?
Three quotes on the same property can differ by €3,000–€6,000. Here is why.
Material specification: One contractor quotes standard concrete tile. Another quotes a premium profile tile with a 40-year guarantee. The material cost difference is €15–€25/m².
Strip vs overlay: A full strip is €1,500–€3,000 more expensive than an overlay. If two quotes do not specify which one they are quoting, they cannot be compared directly.
What is included: Some contractors include scaffolding in the headline number. Most do not. Some include two skips. Some include one. Some quote for chimney repointing as standard. Others add it as an extra.

Use the calculator to blend materials, labour, and your county uplift into one realistic range before you brief contractors.
Structural contingency: Good contractors build in a small contingency for structural surprises. Others quote tight and add change orders once they find rot.
VAT: Always check whether the quoted price includes VAT at 13.5%. A quote excluding VAT on a €10,000 job is actually €11,350 once it is added.

The True Cost: Adding Scaffolding and Extras
A per-m² calculation gets you to materials and labour. Here is what the full bill looks like.
Sample budget for a semi-D with concrete tile:
| Item | Cost |
|---|---|
| Materials and labour (88 m² × €75) | €6,600 |
| Scaffolding | €1,400 |
| Skip hire (2 skips) | €700 |
| Ridge and hip tiles | Included |
| Standard flashing | Included |
| Contingency for hidden rot (15%) | €990 |
| Total budget | €9,690 |
Your actual quote should come in somewhere around this figure for a standard job. Significantly above or below warrants questions.
For a dedicated breakdown of the extras people forget, see hidden costs of roof replacement.
Does the Rate Change With Roof Size?
Slightly. Larger roofs benefit from a small economy of scale because the setup cost (scaffolding, mobilisation, skip hire) is spread across more area.
On a small job (under 50 m²), expect the per-m² rate to be 5–10% higher than on a large job because fixed costs make up a bigger proportion.
On a very large or complex roof (multiple hips, several chimneys, steep pitch), expect the rate to be 10–20% higher than the standard range because of slower work pace and higher risk.
Flat Roof Rates per m²
Flat roofs are priced differently from pitched roofs. The installation method is different and the materials are sold and applied differently.
2026 flat roof rates per m² (installed, excl. scaffolding):
| System | Per m² | Lifespan | Notes |
|---|---|---|---|
| Fibreglass (GRP) | €80–€110 | 25–35 years | Popular for extensions |
| EPDM rubber | €90–€120 | 30–50 years | Very durable membrane |
| Torch-on felt (3-ply) | €65–€90 | 15–25 years | Budget option |
| Liquid waterproofing | €85–€110 | 20–25 years | Good for complex details |
For flat roof insulation, add €25–€50/m² if upgrading to current Part L standards.
Frequently Asked Questions
How do I calculate roof cost in Ireland?
Measure your ground-floor footprint, multiply by 1.4 for a standard pitched roof, then multiply by your material rate per m². Add €800–€3,000 for scaffolding. Budget 10–15% extra for potential structural surprises.
Why is my contractor quoting less per m² than I expected?
They may be quoting an overlay rather than a full strip, or they may have excluded scaffolding and skip hire from the headline number. Always ask what the quote includes before comparing.
Is roofing cheaper in rural Ireland?
Labour rates are lower by about 10–15% outside Dublin and the main cities. However, material delivery costs can be higher in remote areas, which narrows the saving on larger jobs.
What is the cheapest way to re-roof a house in Ireland?
Concrete tile with a synthetic underlay is the most cost-effective option for a standard pitched house. Getting three quotes in autumn or winter when demand is lower also helps. Combining the job with insulation upgrades maximises SEAI grant value.
Does the per-m² rate include VAT?
The rates on this page include VAT at 13.5%. Always confirm this with your contractor before comparing quotes.
