No Full Roof Replacement Needed
Most flat roofs across the region can be restored and waterproofed without removing the existing covering, adding years of reliable service life at a fraction of the replacement cost.
Specialist flat roof repair and waterproofing services across County Louth. Our advanced liquid-applied membrane systems eliminate leaks, restore worn roofs, and deliver lasting protection with manufacturer warranties of up to 25 years.
County Louth's east coast position brings persistent Irish Sea moisture, wind-driven rain, and seasonal temperature swings that subject flat roof structures to relentless wear. Without specialist waterproofing, even structurally sound flat roofs can develop leaks and costly water damage.
Property owners across the region regularly discover standing water on flat roofs and are understandably concerned about the consequences. With conventional roofing materials like felt or bitumen, that concern is justified — traditional systems were simply not designed to endure prolonged water contact.
As the video shows, today's liquid-applied waterproofing systems solve this problem at its root. These specialist membranes are engineered to withstand permanent ponding water without softening, delaminating, or losing 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 County Louth property has an active leak, visible signs of deterioration, or you want to protect against future problems, we develop a bespoke waterproofing solution that safeguards your roof for the long term while keeping cost, disruption, and downtime to a minimum.
Watch: Reconditioning existing felt roofs with liquid membrane
We never cut corners — every project follows a disciplined, proven process built to deliver lasting waterproof performance.
Every project starts with intensive power-washing and decontamination of the entire roof surface, stripping away grime, salt residue, moss, and pollutants. Properties near the coast and port areas accumulate airborne contaminants rapidly, and the waterproofing membrane demands a thoroughly clean substrate to achieve its full bond strength.
Meticulous surface preparation is the foundation of every successful liquid waterproofing installation — no shortcuts, no exceptions.
All moss, lichen, root growth, and trapped debris are systematically removed and drainage outlets fully cleared. The local climate — damp with persistent east coast moisture — encourages organic colonisation, particularly on flat roofs within sheltered industrial estates and between taller commercial buildings where moisture lingers.
Watch: LAVA 20 application on asphalt roof
Watch: Applying liquid membrane over fibreglass matting
Every crack, failed lap, open joint, and corroded fixing across the roof deck is identified and repaired before any waterproofing material 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 carefully controlled, overlapping passes to build a continuous protective barrier.
The system is constructed progressively:
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 give County Louth property owners a high-performance alternative to traditional roofing solutions, delivering reliable, long-term protection with minimal disruption.
Watch: Why installers prefer this system over traditional fibreglass
Most flat roofs across the region can be restored and waterproofed without removing the existing covering, adding years of reliable service life at a fraction of the replacement cost.
The liquid membrane sets to form an unbroken, joint-free barrier — removing the weak points where traditional roofing systems are most prone to leaks.
Liquid waterproofing is applied swiftly without hot works, open flames, or heavy machinery — making it suitable for occupied homes, offices, and commercial premises.
The finished membrane accommodates thermal movement and structural settling, holding its seal through changeable weather conditions.
Engineered to perform in Ireland's most demanding environments — from persistent east coast rain and Irish Sea winds to freeze-thaw cycles common in the northeast.
Reconditioning and waterproofing an existing flat roof is significantly more economical than a full replacement, with lower labour costs, less material waste, and minimal disruption.
Thanks to its exceptional adhesion, flexibility, and durability, this waterproofing system delivers where traditional methods often fall short — providing a proven, long-term solution for flat roof protection across the region.

Waterproofing Engineered to Last
Our flat roof waterproofing systems are installed strictly in accordance with manufacturer specifications and backed by long-term warranties of up to 25 years, giving 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.

For you, this means:
