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.
Expert flat roof repair and waterproofing services in Shannon and the surrounding area. Our proven liquid-applied membrane systems stop leaks, restore ageing roofs, and deliver lasting protection with manufacturer warranties of up to 25 years.
Shannon's location on the Shannon Estuary brings persistent humidity, prevailing westerly winds, and year-round rainfall that test flat roof structures to their limits. Without specialist waterproofing, even well-constructed commercial and industrial roofs can develop leaks and costly water damage.
Property owners and facility managers across the region regularly discover ponding water on flat roofs and are rightly concerned. With conventional roofing materials such as felt or bitumen, those concerns are well-founded — traditional systems were never engineered for prolonged water exposure.
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 Shannon 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 begins with thorough power-washing and decontamination of the entire roof surface, clearing away industrial deposits, moss, algae, and atmospheric contamination. The region's estuary humidity and prevailing westerly weather accelerate surface degradation, and the waterproofing membrane requires a meticulously prepared substrate to bond effectively and perform long-term.
On commercial and industrial roofs, thorough surface preparation is essential — the scale and exposure of these structures demand the highest standards of substrate cleanliness.
All moss, lichen, algae, and accumulated debris are systematically cleared, and drainage systems fully restored to working order. The mild, humid conditions common in the mid-west promote rapid biological colonisation, particularly on large flat roofs where water pools in low spots and drainage channels become blocked.

Watch: Applying liquid membrane over fibreglass matting
Every crack, failed joint, corroded fixing, and damaged detail across the roof deck is identified and repaired before any waterproofing membrane is applied.
As demonstrated in the video, this typically involves:
With the substrate fully prepared and all defects addressed, the liquid waterproofing membrane is applied in controlled, overlapping passes to form an unbroken protective shield across the entire roof area.
The system is built up in stages:
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 Shannon 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 prevailing weather conditions.
Formulated to endure Ireland's demanding conditions — from sustained rainfall and estuary exposure to the seasonal temperature shifts common across the mid-west.
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 Commercial Performance
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.
