Roof replacement in Dublin, done properly.
Nobody wants a new roof. The honest question is whether the old one has earned another repair, and a roofer worth hiring answers it with evidence.
Repair it or renew it
Years alone prove nothing. Slate on sound battens can see out its owners, while tiles over perished felt may be finished at half the age. The real question is how much of the roof still works, and that needs a proper look at the covering, the layers beneath and every earlier repair.
Then do the sums. Each repair pays for access as well as materials, so patching suits a healthy roof and punishes a failing one. A roof that has leaked in three spots within a few years will usually cost less to renew than to patch three more times.
Consider a Blanchardstown house we re-roofed in slate. The trouble there went back to the day it was built: poor slates, poor battens, failed felt. Age and weather had little to do with it. With nothing solid underneath to fix a patch to, repairs would have been the same bad roof bought in instalments. A survey should tell you that before you pay anyone a deposit.
Stripping also reveals what a survey cannot. With the covering gone, rafters and wall plates are exposed, and now and then the timber is in worse shape than it appeared. You hear about it before more work happens, with a price for the extra. The new roof is built up in order: breathable membrane, treated battens, covering, then lead at every wall junction. It earns the Lifetime Leak Guarantee. Choosing between firms? Our guide to choosing roofing contractors in Dublin lists what each one should put in writing.
What a new roof can be covered in.
Natural slate
Dense, dark and durable, provided it is nailed with stainless or copper. A natural fit for older Dublin houses, and for owners who want the roof to outlive the mortgage.
Concrete interlocking tile
The practical pick for most 1990s and 2000s estate houses and bungalows. It weighs less than slate, goes down faster, and takes a dry-fix ridge and verge with no mortar.
Slate-effect covers
A slate appearance for less weight and money. Before you commit we check that your pitch and exposure suit it.
Membrane, battens and ventilation
Vapour-open membrane and treated battens, plus airflow from eaves to ridge so the roof void can dry out.
Period houses
Georgian and Victorian roofs count as restoration: slower, more careful and priced to match. The period property figure is in the table below.
What each price takes in.

What this usually costs.
| Service | Indicative price (2026) | Typical duration |
|---|---|---|
| Concrete Tile Roof | €8,000–€18,000 | 4–10 days |
| Complete Slate Roof | €12,000–€28,000+ | 5–14 days |
| Period Property Restoration | €15,000–€35,000+ | 7–21 days |
Read these as 2026 guide figures, not a quote. The size and slope of a roof, what covers it, how safely we can reach it and what the timbers turn out to be like all move the number. The price you pay is the one written down after the survey, and VAT is added on top at 13.5% for homes.
From the first look to the handover.
Survey
We examine the covering, attic, timbers and past repairs, then say what the roof needs.
Written price
A fixed price covering every stage, with the covering, access and disposal spelled out.
Strip and re-roof
Old roof off, hidden timber checked, new layers laid in order, lead dressed at each detail.
Hand-back
The site is cleared and the guarantee is sent in writing.
What people ask us.
New roof or another repair: how do I decide?
Ask what still works. Good battens and felt favour repair; perished felt, soft batten ends and leaks that keep moving favour replacement. A survey should say which, and show you the evidence.
What will a new roof cost?
Our 2026 guide figures, plus VAT: concrete tile is €8,000–€18,000 over 4–10 days; a complete slate roof is €12,000–€28,000+ over 5–14 days. The fixed price comes after the survey.
Is the Lifetime Leak Guarantee included on a new roof?
Yes, on any complete replacement. A part-roof job or repair carries ten years of written cover on the workmanship instead, and your quote says which applies.
How many days does a re-roof take?
On our guide figures, 4–10 days in concrete tile and 5–14 in slate. Weather, or something nasty under the old covering, can stretch that.
Do I have to move out while the roof is done?
Usually not. The roof comes off and goes back in sections so the house stays covered, and the work is outdoors. Expect noise and scaffolding.
Slate or tile for my Dublin house?
Georgian and Victorian houses generally want slate. Estates from the 1990s and 2000s were designed around concrete tile, which is lighter and cheaper. The structure and pitch decide, and the survey checks both.
Will you tell me if my roof can be saved?
Yes. If a repair will do we say that, with a repair price. Hiring us for the right job beats hiring us for the bigger one.
Can I compare your price with other roofers?
Please do. Have each roofer write down the covering, scaffold, waste removal, lead and guarantee. The list is in our guide to questions to ask a roofer.

Roof Repairs
A stain on the ceiling or a slate on the path: the spot where water gets in is traced and put right, not painted over.
Re-felting & Battening
The membrane and battens under good slates tire before the slates do. Both are renewed and your own slates go back on.
Roof Inspections
A written report with photographs, taken on the slope and from inside the attic, so you know what the roof needs and what it does not.
Lead Flashing & Chimneys
New lead where roof meets wall, stack or valley, and the chimney made sound so it stops soaking up rain.
