Roof Cost Calculator Dublin

A full roof replacement on a typical Dublin three-bed semi runs €9,000 to €14,000 for natural slate and €7,000 to €11,000 for concrete tile, including stripping, new felt and battens, flashings and skip hire. Smaller repair work starts around €450. The honest answer is a range, because the house, the pitch and the access all move the number before a single slate is lifted.

Dublin Roof Costs at a Glance

• Full replacement, three-bed semi (natural slate): €9,000–€14,000 including VAT, scaffold and skip; concrete tile is roughly 20–25% cheaper.
• Full replacement, mid-terrace redbrick in Phibsborough or Drumcondra: €7,500–€12,000, with shared party-wall access often cutting scaffold cost.
• Full replacement, detached house in Castleknock or Foxrock (~150m² roof): €18,000–€28,000 depending on pitch, dormers and chimney count.
• Targeted repairs (slipped slates, cracked ridge, lead flashing to a chimney): typically €450–€1,800 on a standard Dublin two-storey.
• Guttering done at the same time as a reroof: add roughly €1,000–€1,400 for a semi in uPVC, €1,300–€1,800 in aluminium — fitting both in one scaffold visit saves on access.

How much does a new roof cost in Dublin in 2026?

The honest ballpark for a full roof replacement in Dublin is between €7,000 and €28,000, and that spread exists for good reason. A compact 1930s semi in Cabra with a simple two-pitch roof and a straight run to the back garden for a skip is a different job to a 1900s redbrick on Grosvenor Road with valleys, three chimneys, a party-wall scaffold and a conservation-grade Welsh slate specification.

Five things move the price every time, and anyone quoting without seeing them is guessing:

1. Roof area in square metres — the single biggest driver.
2. Material — natural slate, fibre-cement slate, concrete tile or clay.
3. Pitch and complexity — valleys, hips, dormers and chimneys all add labour.
4. Condition of the structure underneath — sound rafters versus rotted ends.
5. Access — a semi with side access versus a mid-terrace needing a pavement licence.

For roofing itself we work with Recommended Roofing's Dublin team — the sister brand covering slates, tiles and flat roofs. This site handles the roofline: gutters, fascia, soffit and downpipes, which almost always need thinking about at the same time as a reroof.

What a Dublin reroof costs by house type

Dublin's housing stock splits into four broad bands, and each one carries its own typical price.

Georgian and Victorian redbrick (Rathmines, Portobello, Phibsborough, Drumcondra)

Original natural slate roofs, usually Blue Bangor or Welsh, often 100+ years old. A full strip and recover with reclaimed or new natural slate on a mid-terrace runs €11,000–€16,000, more if the chimney stacks need rebuilding or lead flashings renewing. These houses almost always need their cast iron guttering repaired or replaced in matching heritage profile at the same time.

1930s and 1940s semis (Cabra, Crumlin, Terenure, Clontarf)

Mostly natural slate originally, many since recovered in concrete tile. A full replacement on a standard three-bed semi:

• Concrete tile: €7,000–€11,000
• Fibre-cement slate: €8,500–€12,500
• Natural slate: €9,000–€14,000

1970s estates (Tallaght, Clondalkin, Coolock, Ballymun)

Concrete tile is standard here. The tiles themselves are often still serviceable at 50 years; it is the felt, battens and ridge mortar that fail. A full strip and recover using the existing tiles where sound, with new felt, battens and dry ridge: €6,500–€9,500. A full retile in new concrete: €8,000–€11,500.

Newer developments (Citywest, Clonsilla, Adamstown)

Usually under 25 years old and rarely needing a full replacement yet. Calls here tend to be ridge tile repointing, lead flashing renewal or storm damage, in the €450–€2,500 band.

Can my roof be repaired instead of replaced?

Often yes — and anyone whose first answer is "it all needs to come off" is not someone to work with. A roof that has lost half a dozen slates in a storm, has a leaking valley or needs the chimney flashings redone is a repair, not a replacement. The honest test is whether the underlying felt and battens have gone. If they have, patching slates one at a time is throwing good money after bad; if they haven't, a targeted fix will hold for years.

What drives the price on a Dublin roof

Roof area. A standard three-bed semi carries roughly 70–90m² of roof surface across both pitches. A larger detached house in Malahide or Rathfarnham can run to 150–200m². Everything scales from there.

Material

Access

Mid-terrace houses in Stoneybatter, Portobello or Ranelagh often need a scaffold licence from Dublin City Council (currently around €85 per month per pavement section), and sometimes a skip permit on top (€40–€50 depending on the area). A detached house with side access and a driveway for the skip avoids both.

Pitch, dormers and chimneys

A straight two-pitch roof is the cheapest shape to work on. Every valley, hip, dormer and chimney adds labour and lead. A Victorian redbrick with three chimneys and two valleys will carry a noticeably higher labour component than a 1970s bungalow of the same footprint.

Condition of the structure

Nobody can price the rafters until the slates are off. A sound structure on a 1930s house is common; soft rafter ends under valleys or around chimney flashings are also common. We flag the risk in the written quote and price any additional carpentry on a day rate before it is carried out, not after.

What about the gutters, fascia and soffit?

If the roof is coming off, the roofline below it needs to be looked at in the same visit. Lifting a scaffold a second time six months later to replace tired uPVC fascia or sagging gutters costs more than doing both together — the scaffold is already there.

Indicative Dublin ranges for a standard semi, done alongside a reroof:

• Full uPVC gutter and downpipe replacement: €1,000–€1,400
• Aluminium seamless guttering: €1,300–€1,800
• Fascia and soffit renewal in uPVC: quoted with the guttering, since the gutter has to come off to reach the board
• Cast iron replacement on a period property: €2,100–€2,800

Every full gutter or roofline replacement carries our 10-year written workmanship guarantee and the Lifetime Leak Guarantee. See our full guttering services for Dublin for how the roofline work is costed on its own.

Are grants available for roofing work in Dublin?

Not for the roof covering itself. SEAI grants under the Better Energy Homes scheme cover attic insulation (up to €1,500) and other energy upgrades, which is often worth doing while the roof is open and the rafters are exposed. If you are planning a reroof, co-ordinating the attic insulation at the same time saves on access and the grant comes off the insulation cost directly.

Roof insurance claims — storm damage from a named storm — are a separate route. Photograph the damage before touching anything, get a written contractor's report, and the home insurer's storm peril usually covers it subject to the excess.

How to get a figure for your own roof

The calculator shape is useful for a ballpark; a figure you can sign off on needs someone on the roof. Our process:

1. Call (01) 265 8463 or send the form. Mon–Sat, 08:00–18:00.
2. Free on-roof inspection. No call-out fee. We go up and look rather than pricing from the ground — the difference between a repair and a replacement is not visible from a driveway.
3. Written quote with a breakdown. Materials, labour, scaffold, skip and VAT, with the guarantee terms in writing before anything is signed.
4. Work carried out by directly employed crews. We do not subcontract.
5. 10-year written workmanship guarantee on everything we install; Lifetime Leak Guarantee on every full gutter or roofline replacement.
