Roof repairs in Dun Laoghaire range from wind-lifted ridge and verge tiles after an easterly blow to a tired flat-roof addition needing new EPDM. This guide covers what roof repairs cost in Dun Laoghaire in 2026, how long they take, and how to tell a proper repair from an unnecessary replacement.
Felt roof repair and full replacement in Blackrock, Dublin South, a typical coastal South Dublin flat-roof job.
Dún Laoghaire is a port town, and its roofs take the full force of the bay's easterly wind. That exposure is relentless on ridges, verges and the more open elevations, and it explains the pattern of faults we find here repeatedly. Ridge and verge tiles are the most common storm-damage call-out, windblown slate damage follows closely, and on the Victorian town stock the lead flashings and valley gutters are a regular priority, since many are original and have long outlived their design life.
The housing itself ranges from mid-Victorian terraces in the town centre to larger Edwardian villas on the surrounding hills, and many of the older properties carry flat-roof rear additions put on over the decades. Those additions age differently from the pitched roof above them. Felt flat roofs fail quietly, and from above, so if no one has been up on yours recently it is worth checking. On a similar job in Blackrock we arrived to find a failing felt roof that had already let water into the building; by the time the ceiling showed a mark, the damage had long since spread beyond the roofline.
The table below shows the indicative ranges we work to. Every figure is before VAT at 13.5%, and every job gets a written fixed-price quote after the free survey, so the number at the end matches the one at the start.
Indicative 2026 price range in euro, excl. VAT at 13.5%
| Repair type | Indicative range (excl. VAT) |
|---|---|
| Roof leak repair (slipped slates, small leaks) | €400, €2,500 |
| Emergency storm damage work | €1,500, €8,000 |
| Emergency tile or slate securing (temporary make-safe) | €200, €500 |
| Temporary weatherproofing | €300, €800 |
| Emergency safety assessment | €200, €400 |
What moves the price within those ranges is the scope and cause of the fault, access and the number of storeys, whether scaffolding is genuinely needed (it is not automatic and is always a separate line if it is), and whether a flat-roof section needs a full recover rather than a localised repair. A proper inspection tells us which end of the range your roof sits at before any work begins.
An emergency call-out makes the roof safe and stops the water getting in. The permanent repair is a separate written quote once conditions allow a proper assessment. This is worth knowing up front: the two things are priced separately and done in the right order, not rushed together.
Wind from the east lifts bedded ridge and verge tiles faster than it does on more sheltered South Dublin streets. Where mortar has cracked or the bed has pulled away, the tile is effectively loose and an opened ridge lets water in quickly on an exposed roof. Dry-ridge and dry-verge mechanical fixing systems eliminate the mortar joint entirely and are worth considering on a Dún Laoghaire roof where re-bedding has already been done once. See our guide to dry ridge and dry verge systems for Dublin roofs.
The Victorian and Edwardian stock carries original lead that is often at the end of its design life. Failed flashing around a chimney apron or an abutment is one of the quieter sources of water ingress; the entry point and the ceiling stain are rarely directly above each other. We strip and relay rather than dress over old lead, and the work is included in the standard repair range above.
Most of the rear additions on older Dún Laoghaire properties were laid in traditional felt. Felt has a lifespan of around 15 to 20 years; we do not recommend it for new work. Where a flat roof has failed or is blistering and lifting, EPDM rubber membrane or GRP fibreglass are the systems we install. Both carry a lifespan of 25 to 35 years and sit within the repair cost range above for typical extension sizes. For larger areas see our guide to flat roof replacement in Dublin.
If the faults are localised and the underlay and roof timbers are sound, a repair is the honest recommendation. Widespread slipping across the whole slope, a brittle or failed underlay, sagging between rafters, or multiple leaks in unrelated locations usually point to a re-roof rather than further repairs. We give you that assessment in writing after the survey, not the most expensive option by default. Our guide on how much roof repair costs in Ireland covers the repair-versus-replace question in more detail.
We are registered with CIRI, the Construction Industry Register Ireland, which means you can check us independently before anyone sets foot on your roof. Our crews are directly employed; we do not subcontract. Every survey is carried out by a qualified roofer, not a salesperson, and you receive a written condition report and a fixed-price quote within 48 hours.
Most Dún Laoghaire repairs are completed in a single day. Larger flat-roof or valley work typically takes two to three days. On urgent jobs we weatherproof the affected area on the first visit before carrying out the permanent fix, and we leave the site clean when we finish.
Every repair carries a written guarantee of a minimum of 3 years, with up to 10 years on major repair work. Replacement work, including flat-roof replacement, carries a 10-year guarantee plus the Lifetime Leak Guarantee. The guarantee is issued in writing before the work starts, not after, and it is automatic on every job, not something you have to ask for. Our crews are our own people, so there is a direct line of accountability if anything needs revisiting.

“Really happy with service provided. They were extremely helpful and efficient from start to finish. An assessment and quote were provided the day after I first got in touch, and the repair was completed within a week. The issue and proposed solution were clearly explained, and I really appreciated that they recommended a proportionate repair rather than simply suggesting everything needed to be replaced. Very professional, straightforward and efficient service. Would definitely recommend!”Alice Daniels, Dublin, ★★★★★ on Google

Most roof repairs in Dún Laoghaire fall between €400 and €2,500 (indicative, 2026, VAT at 13.5% extra). Minor leaks and slipped slates sit toward the lower end; ridge, flashing and flat-roof work runs higher. You get a written fixed-price quote after a free survey, so the figure does not change on completion.
Emergency tile or slate securing to make a roof safe typically costs €200 to €500. Temporary weatherproofing such as sheeting or tarping runs €300 to €800. A structural safety assessment after storm damage is €200 to €400. The permanent repair is a separate quote once it is safe to assess properly.
Most repairs in Dún Laoghaire are finished in a single day. Flat-roof recovers or extensive valley and flashing work take two to three days. If your roof is leaking actively, we weatherproof the affected area on the first visit before carrying out the permanent fix.
Ordinary repairs and like-for-like re-roofing do not need planning permission. You may need it if you significantly change the roof's shape, height or materials, or if the property is protected or in a conservation area, which applies to parts of the Dún Laoghaire town core. We flag any of that during the survey.
The most common causes are slipped or cracked slates, failed ridge and verge mortar, worn lead flashing around chimneys and valleys, and old felt flat roofs. The heavy easterly wind off the bay accelerates all of these, particularly on ridges, verges and the more exposed elevations.
If the faults are localised and the underlay and timbers are sound, a repair is the right call. Widespread slipping, a brittle or fully failed underlay, sagging timbers or multiple unrelated leaks usually point to a re-roof. A free inspection gives you an honest recommendation in writing.
Repairs carry a written guarantee of a minimum of 3 years, up to 10 years on major repair work. Replacement work and flat-roof replacement carry a 10-year guarantee plus the Lifetime Leak Guarantee. The guarantee is issued in writing before the work starts, not after.
We employ our crews directly. We do not subcontract. The people on your roof are our own people, which means there is a direct line of accountability if anything needs to be revisited.
No. VAT at 13.5% applies on top of all figures quoted. Your written quote shows the pre-VAT figure and the VAT separately so there are no surprises.
Scaffolding is not automatic. It is only included where the building is very high or on a busy street with heavy pedestrian traffic. Where it is needed it appears as a separate line on the quote, never buried in the price. If you can source suitable scaffolding at a better rate yourself, you are welcome to do so.
Call us on 01 2657795 or use the contact form at recommendedroofing.ie/contact/. A qualified roofer carries out the survey, not a salesperson, and you receive a written condition report and fixed-price quote within 48 hours. The survey is free and there is no obligation.
Storm damage is often covered under a standard home insurance policy, though the terms vary by insurer and policy. We provide a written condition report and photographic evidence that can support an insurance claim. Contact your insurer directly to confirm what your policy covers before any work begins.
