New Roof Installation Dublin — Slate, Tile & Flat Systems
When a Repair Isn't Enough Anymore
Every roof eventually reaches the point where patching it stops making sense — where the fixings are failing across the whole roof rather than in one spot, where the timber underneath has started to go, or where you're simply tired of calling someone out every winter for the same house.
Mr Roofing installs new roofs across Dublin — natural slate, concrete and clay tile, and flat roof systems for extensions and outbuildings. Free survey, 25-year written guarantee, and honest advice on what your property actually needs rather than what's easiest for us to sell.
If your roof's being stripped back anyway, it's often the most cost-effective point to improve insulation — since the roof void is already fully accessible. Depending on your circumstances, this may also be a point where SEAI grant schemes are relevant for insulation upgrades carried out alongside roofing work. Worth raising during the survey if it's something you'd like us to look into for your specific situation.
5 Star Rated For New Roofs
Had Mr Roofing replace our roof after storm damage last winter. Brilliant service from start to finish — fair price, tidy team, and excellent workmanship. Highly recommended
Called them out for a chimney repair that two other roofers had ignored. They spotted the problem straight away, explained everything clearly, and had it sorted within a few days.
Got our fascias, soffits and guttering replaced, the difference is incredible. Turned up on time and the finish is perfect. Will definitely be using Mr Roofing again.
New Roof Systems We Install
Natural Slate Roofs
The premium, longest-lasting option, and the standard choice on period Dublin properties where matching the original roof matters. Slate handles the city's coastal exposure — wind, salt air, freeze-thaw cycles — better than almost anything else on the market.
Concrete & Clay Tile Roofs
The durable, cost-effective workhorse for full re-roofs on standard semis and terraces across the city. A strong, long-lasting option without the price tag of natural slate.
Fibre-Cement Slate
A reconstituted slate alternative that sits between tile and natural slate on both cost and lifespan — a genuine middle option worth considering depending on your budget and property.
Flat Roof Installation
EPDM rubber and GRP fibreglass systems for extensions, garages, and dormers, built with the correct fall from the outset rather than repeating whatever mistake caused the last one to fail.
Full Strip & Re-Roof
Complete removal of the old roof covering, inspection and repair of the timber underneath, and a full new roof built up properly — not just tiles laid over old problems.
Do You Actually Need Planning Permission?
This is one of the first questions people ask, and the honest answer for most Dublin homes is no.
A like-for-like re-roof — replacing the roof with the same or a similar material and keeping the existing shape, height, and profile — is generally treated as maintenance and doesn't require planning permission.
You're more likely to need it if you're changing the roof's shape, height, or profile, or if your property is a protected structure or sits within a conservation area — which covers a meaningful chunk of Dublin, including parts of the city centre and a number of older villages across the county.
We flag this during the free survey, before anything's agreed, so there are no surprises partway through the job.
Choosing the Right Material for Your Property
This isn't a one-size-fits-all decision, and the honest answer depends on your property, your budget, and how long you actually want the roof to last.
Natural slate is the longest-lasting option available, capable of a century or more when correctly installed, and performs particularly well in Dublin's coastal exposure areas where salt-laden wind and freeze-thaw cycles wear down softer materials faster. It's also generally the required or expected material on protected structures and conservation-area properties, where matching the original roofline matters for planning compliance.
Concrete tile is the most common full re-roof choice on standard Dublin housing — semis and terraces from the mid-20th century onward — offering strong durability at a more accessible price point than slate.
Fibre-cement slate gives you the look of natural slate at a lower cost and weight, a genuine middle-ground option worth considering if slate's the look you want but the full natural slate budget isn't there.
We'll talk through what actually suits your specific roof and budget during the survey — not steer you toward whichever material we'd rather install.
Roof Replacement Frequently Asked Questions
How long does a new roof take?
Depends on size and roof shape, but a standard semi-detached home typically takes several days to a week or so. Weather can add time, which is exactly why we weatherproof at the end of each day rather than leaving things exposed.
Do I need to move out during the work?
No — new roof installations are done from the outside, so you can stay in the house throughout, though it's obviously noisier than a normal week.
What happens if you find rot or damage once the old roof's stripped back?
We tell you straight away, show you what we've found, and give you a clear price for the additional work before proceeding — never a surprise on the final invoice.
Is a new roof covered by the same 25-year guarantee?
Yes — full re-roofs carry the same 25-year written guarantee as our repair work.
Can you match the existing roof on a period property?
In most cases, yes — matching slate type, tile profile, and roofline is exactly the kind of work required on protected structures and conservation-area properties, and it's something we plan for from the survey stage.
