A new roof installation in Rathfarnham is a big decision, and the right choice depends on your home's age, roof size and the materials that stand up to Irish weather. This guide covers what a new roof costs in Rathfarnham in 2026, how long installation takes, and how to choose a roofer you can trust.
Rathfarnham runs from the village up towards the Dublin Mountains, and its housing stock shapes every new roof we install. You have 1930s to 1980s semi-detached estates, some Victorian terraces near the village core, and 1990s and 2000s infill filling the gaps. Many of these homes also carry flat-roof rear extensions added over the decades.
That mix matters, because a Victorian slate terrace and a 1970s concrete-tile semi need very different roofs. We install new roofs on all of them across D14 and D16, and every project starts with a proper survey of the structure, the timbers and what will actually suit the house.
Rathfarnham sits higher and more exposed than the coastal South Dublin suburbs. That means stronger wind loading on ridges and verges, heavier rainfall, and cold air pooling in winter that punishes weak fixings and poor detailing.
For Irish weather, the materials that last are natural slate, concrete tile and fibre cement slate. Natural slate suits the older terraces near the village and lasts generations. Concrete tile is a hard-wearing, cost-effective choice for the semis, and fibre cement gives a slate look at a lighter weight. Whatever the material, it is the flashing, ventilation and fixing detail that decides how a new roof copes with Rathfarnham's exposure.
Every roof is different, but these are honest Rathfarnham ranges for 2026. We give you a written, fixed price after a free survey, so there are no surprises at the end.
What moves the price is roof size, the material you choose, the roof's shape and pitch, access, and whether the timbers or chimney need attention once the old roof comes off. A full survey tells us which side of the range you are on before any commitment.
We are a CIRI-registered contractor (Construction Industry Register Ireland), so you can check us independently before anyone sets foot on your roof. Every survey is done by a qualified roofer, not a salesperson, and you get a written specification and a fixed-price quote within 48 hours.
A typical new roof in Rathfarnham takes three to seven days depending on size, material and weather. We strip the old covering, inspect and repair the timbers, fit new felt and battens, and lay your chosen slate or tile with fresh flashing and ventilation. We keep the house weathertight throughout, tidy up fully, and back the work with a written guarantee, so you will know the timeline and the disruption before we start.

A new roof in Rathfarnham typically costs between €8,000 and €25,000 in 2026, depending on the size of the roof and the material you choose. A smaller terrace or mid-size semi usually falls at the lower end, while natural slate or a large, complex roof reaches the top. You get a written, fixed price after a free survey, so the figure never changes on completion.
Most new roofs in Rathfarnham take three to seven days to install. The exact time depends on the roof size, the material, the roof's shape and the weather. We keep the house weathertight throughout the job, so you are never left exposed between stages.
Natural slate, concrete tile and fibre cement slate all stand up well to Irish weather. Natural slate lasts generations and suits older terraces, concrete tile is a hard-wearing and cost-effective choice for semis, and fibre cement offers a slate look at a lighter weight. In an exposed spot like Rathfarnham, the quality of the flashing, fixings and ventilation matters as much as the material itself.
A like-for-like re-roof in the same style and materials does not usually need planning permission in Dublin. You may need it if you change the roof's shape, height or materials significantly, or if the property is protected or sits in a conservation area, which affects parts of the Rathfarnham village core. We flag any of that during the survey so there are no surprises.
Look for a CIRI-registered contractor you can check independently, proper public liability insurance, and a written fixed-price quote rather than a verbal estimate. Ask whether the roofers are directly employed or subcontracted, and whether the work comes with a written guarantee. Recommended Roofing gives you a free survey by a qualified roofer, €6.5 million public liability cover, and a 10-year written guarantee issued before the work starts.
