Roofing FAQs
A full roof replacement on a three-bed semi-detached house costs €8,000 to €15,000 including scaffolding, materials, and labour. Larger detached homes cost €12,000 to €22,000. Natural slate is at the upper end, concrete tiles at the lower end. Flat roof replacement costs €3,000 to €7,000 depending on size and system used. These prices include scaffolding. Repairs (replacing broken slates, repointing ridge tiles, fixing flashings) cost €300 to €2,000 depending on the scope.
Natural slate: 80 to 100+ years for quality Welsh or Spanish slate. Concrete tiles: 40 to 60 years. Flat roof (felt): 15 to 20 years. Flat roof (single-ply membrane): 25 to 35 years. Flat roof (fibreglass/GRP): 25 to 30 years. These are lifespan estimates for well-installed roofs with regular maintenance. A poorly installed roof can fail far sooner. Ridge tiles, flashing, and guttering typically need attention well before the main roof covering.
Warning signs include: multiple slipped, cracked, or missing slates or tiles; daylight visible through the roof boards from inside the attic; damp patches on bedroom ceilings; sagging or uneven roof lines; crumbling mortar on ridge tiles; persistent leaks despite repairs; and the age of the roof (concrete tiles over 50 years, felt flat roofs over 20 years). If you are spending more than €1,000 per year on repairs, a full replacement is likely more cost-effective.
Replacing your roof on a like-for-like basis (same material, same colour, same profile) does not require planning permission. Changing the roofing material (e.g., from slate to tile) or colour may require permission in some cases, particularly for protected structures or homes in Architectural Conservation Areas. Adding rooflights or dormers requires planning permission in most cases.
If the underlying structure (rafters, battens, felt) is sound and only a small area of slates or tiles is damaged, repair is the right choice. If the felt is disintegrating (visible as black dust in the attic), battens are rotting, or slates are failing across multiple areas, replacement is usually more cost-effective than patching repeatedly. A good roofer will give you an honest assessment. Get a second opinion if you are unsure.
Natural slate is the traditional and still the best overall choice for Irish pitched roofs. It is impervious to water, frost-resistant, wind-resistant when properly fixed, and lasts 80 to 100+ years. Spanish slate is the most common (good quality at moderate cost), while Welsh slate is premium. Concrete tiles are a good budget alternative with a 40 to 60 year lifespan. For flat roofs, fibreglass (GRP) and single-ply membranes offer the best balance of durability and cost.
