If you are planning a roof replacement or need to replace an ageing or damaged roof, A O Leary Roofing & Renovation is a trusted re-roof specialist serving Cork City, County Cork, and County Kerry. With constant Atlantic winds, heavy rain, sudden weather changes, and long damp winters, roofs across the South West of Ireland face far greater strain than most.
When an existing roof begins to fail, minor issues can quickly develop into serious structural problems. For this reason, investing in a professionally completed roof replacement is one of the most important long-term upgrades you can make to protect your property. For new builds or extensions, you can also view our new roof installation services.
With over 20 years of roofing experience, our team delivers complete solutions for replacing existing roofs, built for durability, weather resistance, and long-term performance.
Professional Roof Replacement Services Built for Irish Weather
Our services for replacing ageing and damaged roofs are designed specifically for the challenging weather conditions found across Cork and Kerry. Properties in this region remain exposed to Atlantic winds, driving rain, and prolonged damp conditions throughout the year. As a result, every project focuses on strength, protection, and long-term reliability.
From full roof renewals to structural strengthening, insulation upgrades, and proper ventilation systems, we tailor each solution to the needs of your home or building. We install high-performance breathable membranes, secure fixing systems, and weather-resistant materials to prevent future leaks, reduce heat loss, and improve overall roof performance.
Each project is completed using Irish-approved roofing materials and correct installation practices suitable for both coastal and inland environments. The result is a safer, stronger, and more reliable roof that delivers lasting peace of mind.
Roof Replacement for Residential Properties
We are experienced residential specialists carrying out replacement work on:
- Detached homes
- Semi-detached houses
- Bungalows
- Extensions and garages
- Older cottages and farmhouses
From the initial inspection through to final clean-up, we manage the entire process carefully, keeping disruption to your home and family to a minimum.
Commercial and Industrial Roof Replacement Specialists
We also provide professional replacement services for commercial and industrial properties across Cork and Kerry. If your existing roof has reached the end of its lifespan, suffered storm damage, or no longer meets modern performance standards, our team delivers complete solutions with precision and care.
We work with a wide range of roofing systems, including slate, tiles, metal, and modern flat roofing systems, ensuring the finished roof improves durability, appearance, and long-term weather resistance while remaining suitable for Irish conditions.
What Is Included in Our Roof Replacement Service
Every project includes:
- Safe removal of existing tiles, slates, or roofing materials
- Structural roof inspection and timber checks
- Installation of new breathable membrane and underlay
- Replacement using slate, tile, metal, or flat roofing systems
- New ridge protection systems
- Lead work and flashing upgrades
- Ventilation and full weather sealing
- Optional fascias, soffits, and guttering upgrades
This ensures your new roof is secure, weather-resistant, and built to last.
When Roof Replacement Is the Right Option
Replacing an existing roof is often recommended when repairs are no longer cost-effective. Common signs include:
- Regular roof leaks
- Cracked, loose, or missing tiles
- Sagging roof lines
- Water staining on ceilings
- Rotten or weakened roof timbers
- Ongoing storm damage
- Rising heating costs caused by heat loss
An early inspection can often prevent far more serious and expensive damage.
