New Roofs and Re-Roofing in Dublin

Concrete tile or natural slate re-roofs with a 25-year guarantee and a price agreed before any work starts.

What's included

  • Old tiles or slates, battens and felt stripped and taken away in a skip we supply
  • Breathable membrane and new treated battens fixed to the rafters
  • Concrete tiles or natural slate laid to the manufacturer's spec, with matching ridge and verge
  • Lead flashings, valleys and chimney soakers renewed, not reused
  • Scaffolding, skip and clean-up priced in the quote, not added later
  • 25-year guarantee on the new roof

Signs you need this

  • You are repairing the same roof two or three times a year
  • The felt under the tiles is brittle and tearing when you look up from the attic
  • Slates are sliding off in every storm because the nails have rusted through
  • Concrete tiles are crumbling at the edges or carrying heavy moss
  • The roof is 50 years old and has never been replaced

How the job runs

  1. 1Book a free on-site roof check and we survey the roof, attic and chimneys with photos.
  2. 2You get your quote with tile and slate as options, scaffolding and skip included.
  3. 3We agree a start date, put up the scaffolding and strip and re-cover the roof in sections so the house is never left open overnight.
  4. 4Final walk-round with photos, the 25-year guarantee and the manufacturer warranties on the materials.

When a roof needs replacing rather than repairing

A roof is worth re-covering when the parts you cannot see have failed. On the concrete-tiled semis built across Dublin from the 1960s to the 1980s that usually means the bitumen felt has gone brittle and torn, the battens have softened and the tiles are crumbling at the edges after 50 winters. On the slate terraces in Clontarf, Drumcondra and Ranelagh it is nail sickness: the iron nails rust through and slates come down in every storm. If you are paying for repairs two or three times a year, the money is better spent on a roof that will last another 50.

What the job involves

We strip the old covering, felt and battens back to the rafters and check the timber. Anything soft is replaced and priced separately, never buried in the tile cost. A breathable membrane goes on, new treated battens are set to the tile or slate gauge, and the roof is covered in concrete interlocking tiles or natural slate. Ridges and hips go on as a dry-fix system where mortar kept cracking, valleys and chimney flashings are renewed in lead, and vents are added at the eaves and ridge so the attic stops sweating. Flat sections such as a rear extension or porch get torch-on felt, GRP fibreglass or EPDM.

What affects the price

Every re-roof is priced after a free survey. What moves it:

  • Roof area and pitch: a detached house has far more roof than a terrace, a steep pitch is slower, and every chimney, valley and hip means leadwork.
  • Material: natural slate costs more than concrete tile because it is dearer and slower to lay, so both are quoted as options.
  • Scaffolding: every re-roof needs it, and the height of the house, a narrow side passage or a conservatory under the eaves change how much.

The price is agreed before any work starts, and there are no hidden charges.

The free survey comes first

A roofer surveys the roof, the attic and the chimneys, photographs everything, and you get your quote with tile and slate as options and photos of what we find. The price covers strip and disposal, membrane and battens, covering, leadwork, ventilation, scaffolding and skip, and it is agreed before any work starts. No hidden charges.

The 25-year guarantee

Every new roof build carries a 25-year guarantee, and the Laydex, Soprema and RoofTX materials we use carry 20-year manufacturer warranties on top. We are fully insured, we have completed over 1,700 roofs across Dublin, Wicklow and Kildare, and the site is cleared and swept before the scaffolding comes down.

FAQ

New roofs: questions we get asked

How much does a new roof cost in Dublin?

Every re-roof is priced after a free roof survey, because roof area, pitch, chimneys, valleys and access all change the job. Tile and slate are quoted as options, the price is agreed before any work starts, and there are no hidden charges.

How long does a re-roof take?

Most 3-bed semis take about a week on site, longer for slate or a detached house. The roof is stripped and re-covered in sections and covered before we leave each evening, so you stay in the house throughout.

Is scaffolding included in the price?

Yes. Scaffolding, the skip and the clean-up are all in the price you agree, so you know exactly what is included and nothing is added afterwards.

What guarantee do I get?

A 25-year guarantee on the new roof build, plus the 20-year manufacturer warranties on Laydex, Soprema and RoofTX materials where they are used.

Do I need planning permission to replace my roof?

Replacing a roof like for like on a house does not normally need planning permission. Changing the roof profile, adding dormers or working on a protected structure can, and we tell you at the survey if your job is one of those.

What happens if it rains mid-job?

The roof is only opened in sections we can close and cover before we leave each evening. Heavy rain or high wind can pause work for safety, so a wet day rarely changes the finish date by much.
