No Full Roof Replacement Needed
The vast majority of flat roofs across the region can be restored and waterproofed over the existing covering, dramatically extending the roof's service life at a fraction of the replacement cost.
Professional flat roof repair and waterproofing services across Kilkenny city and county. Our specialist liquid-applied membrane systems seal leaks, restore ageing roofs, and provide enduring protection with manufacturer warranties of up to 25 years.
Kilkenny's inland southeast position and Nore valley location bring consistent rainfall, seasonal humidity, and temperature variation that steadily wear down flat roof structures. Without specialist waterproofing, even well-maintained roofs can develop leaks and progressive water damage.
Property owners and facility managers across the region frequently notice ponding water on flat roofs and are rightly concerned. With conventional roofing materials such as felt or bitumen, those concerns are justified — traditional systems were never designed for prolonged water contact.
As the video demonstrates, modern liquid-applied waterproofing systems solve this problem at source. These advanced membranes are purpose-built to withstand permanent ponding water without softening, lifting, or compromising their protective seal.

As the video illustrates, the vast majority of flat roof problems can be resolved without tearing off the existing roof. Most of the local properties we treat have their roofs reconditioned and reinforced using liquid waterproofing membranes combined with fibreglass reinforcement matting. We also offer specialist asbestos roof waterproofing and polyurea roof coating systems for demanding applications.
This approach enables us to:

Watch: Reconditioning existing felt roofs with liquid membrane
We never take shortcuts — every project follows a rigorous, proven process designed to deliver lasting waterproof performance.
Every project opens with intensive power-washing and decontamination of the full roof surface, removing dirt, moss, algae, and environmental deposits. The region's inland humidity and Nore valley moisture promote surface contamination, and the waterproofing membrane needs a thoroughly prepared substrate to bond properly and deliver long-term performance.
Achieving a clean, sound roof surface is the single most important step in any liquid waterproofing installation — no exceptions.
All moss, lichen, root infiltration, and accumulated debris are methodically removed, and every drainage outlet restored to full working order. The mild, damp conditions typical of the southeast interior promote persistent organic colonisation, especially on flat roofs sheltered between commercial buildings and on older residential properties throughout the area.

Watch: Applying liquid membrane over fibreglass matting
Every crack, compromised joint, worn fixing, and damaged detail across the roof deck is located and repaired before any waterproofing membrane is applied.
As demonstrated in the video, this typically involves:
With the substrate fully prepared and every defect addressed, the liquid waterproofing system is applied in measured, overlapping passes to create a continuous, unbroken protective barrier.
The system is constructed layer by layer:
The finished result is a continuous, seamlessly bonded waterproof membrane that shields the roof against ponding water, severe weather, and thermal movement for decades.
Modern liquid-applied waterproofing systems offer Kilkenny property owners and facility managers a proven, high-performance alternative to traditional roofing methods — delivering long-lasting results with minimal disruption.
Watch: Why installers prefer this system over traditional fibreglass
The vast majority of flat roofs across the region can be restored and waterproofed over the existing covering, dramatically extending the roof's service life at a fraction of the replacement cost.
The liquid membrane cures to form an unbroken, joint-free shield — eliminating the seams and weak points where traditional roofing systems are most vulnerable to leaks.
Liquid waterproofing is applied quickly without hot works, open flames, or heavy plant — ideal for homes and businesses throughout the area.
The finished membrane moves with thermal expansion and structural settlement, holding its seal through changeable weather conditions.
Formulated to endure Ireland's conditions — from sustained rainfall and inland humidity to the seasonal temperature shifts common across the southeast.
Reconditioning and waterproofing an existing flat roof costs a fraction of full replacement, with lower labour, reduced material waste, and minimal disruption to your property.
Owing to its exceptional adhesion, flexibility, and longevity, this waterproofing system excels where traditional methods fail — providing a proven, long-term solution for flat roof protection across the region.

Our flat roof waterproofing systems are installed strictly in accordance with manufacturer specifications and backed by long-term warranties of up to 25 years, providing property owners reliable protection and complete peace of mind. We utilise advanced systems such as the LAVA 20 waterproofing system for proven, long-term results.
As demonstrated in the video, many roofs that appear to be at the end of their life do not need to be stripped out or replaced. In many cases, existing felt roofs — even those decades old — can be professionally cleaned, reconditioned, detailed, and fully waterproofed using advanced liquid-applied systems. Even valley leak repairs can be addressed as part of the reconditioning process.
