How Much Does a Roof Replacement Cost in 2026?

A new roof is one of the biggest single repairs most homeowners ever pay for — and one of the hardest to price, because two houses on the same street can differ by thousands of dollars. In 2026, a typical asphalt-shingle replacement runs about €8,000 to €18,000 with premium materials and complex roofs pushing well past €25,000.

This guide breaks the number down honestly: what you are actually paying for, how each material compares, the job factors that move the price up or down, and the exact line items to look for on a quote so you can compare bids apples-to-apples.

The short answer: cost per square metre

Roofers price by the "square" (a 10×10 ft area, or 100 sq ft). A typical ~185 m² home has roughly 20–24 squares of roof once you account for pitch and overhangs. In 2026, installed costs by material look like this:

• Asphalt (3-tab): €5–€5 / sq ft — the budget standard, ~15–20 yr life.
• Architectural asphalt shingles: €5–€10 / sq ft — the most common choice, ~25–30 yr life.
• Metal (standing seam): €10–€15 / sq ft — 40–70 yr life, energy-efficient.
• Cedar shake: €10–€15 / sq ft — premium look, high maintenance.
• Slate or clay tile: €10–€30+ / sq ft — 75–100 yr life, needs reinforced framing.

What actually drives your price

Material is only half the story. These factors routinely swing a quote by thousands:

• Roof size and pitch — steeper roofs are slower and less safe to work on, so labour climbs.
• Tear-off vs. overlay — removing old layers adds €0–€0 / sq ft plus disposal fees.
• Number of layers and decking condition — rotted plywood found mid-job is a common change order.
• Complexity — valleys, dormers, skylights, chimneys and multiple facets all add labour.
• Access and stories — a three-story or hard-to-reach roof costs more to stage.
• Region and season — peak demand after storms drives prices up locally.

How to read a roofing quote

A trustworthy quote is itemized. Before you sign, make sure it spells out each of these — vague one-line bids are where surprises hide:

1. Tear-off and disposal (how many layers, skip included?).
2. Underlayment and ice-and-water shield (code often requires it at eaves and valleys).
3. Decking replacement rate — a per-sheet price for any rotted plywood found.
4. Flashing — new drip edge, valley, step and chimney flashing (never reuse old flashing).
5. Ventilation — ridge vent or box vents; poor ventilation voids many shingle warranties.
6. Warranty — separate the manufacturer material warranty from the tradesman’s workmanship warranty.
7. Cleanup and a magnetic nail sweep of the garden.

When repair beats replacement

If your roof is under ~15 years old and the damage is localized — a few missing shingles, one leak around a vent — a targeted repair (€400–€1,500) is usually the right call. Replace when you see widespread granule loss, curling or cupping shingles, multiple active leaks, daylight in the attic, or sagging (a structural red flag, get it inspected fast).

Insurance often covers storm and hail damage. Document it with photos and dates before any work begins, and get your own inspection rather than relying solely on a tradesman who is also filing your claim.

Roofing costs in Ireland

Figures here are in euro for a typical national job, with Dublin at the higher end. Irish roofs are typically pitched slate or concrete tile, and the wet, windy Atlantic climate makes sound flashing, ridge work and guttering especially important. Flat roofs on extensions are usually felt, GRP or EPDM.

Re-roofing should meet the Building Regulations, and scaffolding is a normal cost on two-storey homes. Confirm your roofer is insured and tax-compliant, and in a protected structure or Architectural Conservation Area check what materials are permitted before starting.
