A roof replacement is one of the biggest jobs a Cork home will ever need, so it's worth getting right. We replace roofs that are past economic repair — perished underlay, cracked ridge mortar, repeat leaks in different spots, or storm damage across a large area. Every job starts with a free drone and thermal survey so you can see exactly what's wrong before committing, followed by a fixed written quote held for 30 days. We strip the old covering, renew battens and breathable membrane, fit new ridge, valley and chimney lead, and re-cover in your chosen material — natural slate for period homes, concrete or clay tile for estate properties. Our own roofers do the work, the site is protected throughout, and the finished roof is backed by a 20-year workmanship guarantee.
We start with a practical assessment, explain the condition of the roof, and agree the right scope before work begins. You get updates during the job, daily site care where needed, and a final review before handover.
Timing depends on access, weather, materials, and the scale of the work, but our team keeps the process straightforward from first call to completion.

Ask About Roof ReplacementFor a typical 3-bed semi (about 100 sqm), a full re-roof is roughly €11,000–€16,000 in concrete tile or €18,000–€26,000 in natural slate, ex-VAT and before scaffolding. Coastal exposure adds 10–15%. See our cost of a new roof in Cork 2026 guide for ranges by house type, then book a free survey for a firm price.
Most concrete-tile re-roofs on a standard Cork semi take 3–5 working days including scaffolding; natural slate takes 5–8 days because every slate is nailed individually. Weather is the main variable — we plan around Met Éireann forecasts and don’t strip a roof with heavy rain due inside 48 hours.
Replace when the roof is past its lifespan, the underlay has perished, you’re getting repeat leaks in different spots, or more than about a quarter of the slates or tiles are damaged. Repair when the covering is sound and the problem is local. A free drone survey settles borderline cases without guesswork.
Yes — two layers. The manufacturer warranty on materials (typically 10–25 years depending on product) and our own 20-year workmanship guarantee covering everything we install, both issued in writing at completion.
