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 Waterford 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.
Waterford's southeast coastal position and Suir Estuary proximity bring persistent humidity, seasonal rainfall, and temperature fluctuations that steadily wear down flat roof structures. Without specialist waterproofing, even well-built flat roofs can develop leaks and water damage over time.
Property owners across the region frequently notice ponding water on flat roofs and are justifiably concerned. With conventional roofing materials such as felt or bitumen, that concern is warranted — these 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:
Whether your Waterford property has an active leak, visible weather damage, or you simply want to protect against future problems, we develop a tailored waterproofing solution that delivers lasting roof protection with minimal cost, disruption, and downtime.
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 starts with intensive power-washing and decontamination of the full roof deck, stripping away dirt, moss, algae, and atmospheric residue. The region's damp southeast climate and Suir Estuary humidity accelerate surface degradation, and the waterproofing membrane needs a clean, sound substrate to achieve its full bonding strength.
A properly cleaned and prepared roof surface is the single most important step in delivering a waterproofing system that lasts.
All moss, lichen, root growth, and trapped debris are carefully removed, and every drainage outlet fully cleared. The mild, humid southeast conditions promote rapid organic colonisation, especially on sheltered flat roofs in residential estates and between commercial buildings where moisture collects.

Watch: Applying liquid membrane over fibreglass matting
Every crack, open joint, worn fixing, and damaged detail across the roof is identified, repaired, and reinforced before any waterproofing material is applied.
As demonstrated in the video, this typically involves:
Once the substrate is fully prepared and all repairs complete, the liquid waterproofing system is applied in carefully controlled, overlapping passes to build a continuous protective shield.
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 Waterford property owners 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 southeast weather conditions.
Formulated to endure Ireland's demanding conditions — from sustained rainfall and coastal 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.

Waterproofing Built for the Southeast
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.
