Roof repairs in Killiney range from a lead valley replacement on a large Victorian house to hip and ridge mortar failure after a storm off the bay. This guide covers what roof repairs cost in Killiney in 2026, how long they take, and how to tell a proper repair from an unnecessary replacement.
Killiney is home to some of South Dublin's largest and most significant Victorian and Edwardian properties, and many are listed or sit within conservation areas. These are big detached houses with roofs to match, set high above Killiney Bay.
These are high-value A96 roofs where the detailing has to be right, and the sensitivity of listed and conservation properties means a careful hand. We work across the hill and the bay elevations on slate and lead, and every job starts by reading what the roof is actually telling us before we quote a cent.
The exposed coastal position on the bay means roof surfaces here face heavy wind and salt exposure. That combination speeds up the deterioration of ridges, hip mortar and flashings on these large-footprint homes.
The complex roof geometry is the other factor. Multiple hips, valleys, dormers and chimney stacks multiply the number of potential failure points, so lead valley replacement, chimney stack repairs, ridge and hip work, and skylight maintenance on the larger detached properties are all common projects here. On a roof this size a single failed valley can put a lot of water into the structure quickly, so early attention pays.
Every roof is different, but these are honest Killiney ranges for 2026. After a free survey you get a written, fixed price, so the figure at the end matches the figure at the start.
What moves the price is scope, the height and access on these big detached houses, the material, and how many hips, valleys and stacks are involved. A proper inspection tells us which end of the range your roof sits at.
We are a CIRI-registered contractor (Construction Industry Register Ireland), so you can check us independently before anyone goes up on a valuable roof. Every survey is carried out by a qualified roofer rather than a salesperson, and you get a written condition report and a fixed-price quote within 48 hours.
Most Killiney repairs are finished in a single day, with larger lead valley or multi-hip work taking two to three. On these large exposed roofs we spec the lead and flashings to stand up to wind and salt, weatherproof anything urgent on the first visit, and work sympathetically where a property is listed or in a conservation area. You will know the timeline and the disruption before we lift a slate.

Most roof repairs in Killiney fall between €300 and €2,500 in 2026. A slipped slate or small leak is typically €300 to €800, while ridge, hip, chimney and lead valley work on the large period roofs runs higher. You get a written, fixed price after a free survey, so the figure never changes on completion.
Most repairs in Killiney are completed in a single day. Larger jobs, such as lead valley or multi-hip work on a big detached roof, take two to three days. If your roof is leaking, we weatherproof the affected area on the first visit before carrying out the permanent fix.
Ordinary roof repairs and like-for-like re-roofing do not need planning permission in Dublin. 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 many of Killiney's larger homes. We flag any of that during the survey.
The usual culprits are slipped or cracked slates, failed ridge and hip mortar, and worn or corroded lead flashing around chimneys and valleys. Blocked or broken gutters backing water up under the roofline are another common source. In Killiney, heavy wind and salt off the bay, plus complex roof geometry, accelerate all of these.
As a rule of thumb, if the problems are localised and the underlay and timbers are sound, a repair is the right call. Widespread slipping, sagging, multiple leaks and a brittle or failed underlay usually point to a re-roof. A free inspection settles it: we give you an honest recommendation, not the most expensive option.
