No Roof Replacement Required
Existing roofs can be restored and waterproofed without costly strip-out, significantly extending roof lifespan.
Professional flat roof repair and waterproofing solutions designed to stop leaks, extend roof life, and protect your property for decades. Our liquid-applied waterproofing systems come with manufacturer-backed warranties of up to 25 years.
Flat roofs are constantly exposed to standing water, harsh weather conditions, and temperature fluctuations, making them one of the most demanding roof types when it comes to long-term waterproofing.
Many property owners worry when they see ponding water on a flat roof. This concern usually comes from experience with traditional roofing systems such as felt or asphalt, which are not designed to tolerate permanent standing water and can deteriorate over time.
As shown in the video, this is not an issue with modern liquid-applied waterproofing systems. These systems are engineered to perform even with permanently ponding water, without breaking down, softening, or losing their waterproof properties.
Our flat roof waterproofing systems:
At Dublin Protective Coatings, we specialise in flat roof leak repair, sealing, and complete waterproofing systems for both residential and commercial properties. From small kitchen extensions and garages to apartment blocks and industrial units, we deliver long-term, reliable roof protection—without the cost and disruption of full roof replacement.
We provide professional flat roof repair and waterproofing solutions using modern liquid-applied membrane systems designed to seal, reinforce, and extend the life of existing roofs.
Our systems are ideally suited for:
As shown in the video, the majority of flat roof issues can be resolved without full roof replacement. In fact, most flat roofs we work on are reconditioned rather than removed, using advanced liquid waterproofing systems in combination with reinforcement layers such as fibreglass matting.
This approach allows us to:
Whether your roof is actively leaking, showing signs of wear, or simply requires preventative protection, we design a tailored waterproofing solution that future-proofs your roof while keeping costs, downtime, and disruption to a minimum.
Watch: Reconditioning existing felt roofs with liquid membrane
We don't just coat over problems — we fix them properly using a structured, proven process designed to deliver long-term waterproof performance.
We begin with thorough roof cleaning to remove dirt, moss, algae, and surface contamination. This step is critical to ensure the waterproofing system bonds correctly to the existing roof surface.
Only a clean and dry roof substrate is suitable for liquid-applied waterproofing systems.
All organic growth, roots, and trapped debris are carefully removed. Vegetation can retain moisture, damage roof layers, and create weak points that eventually lead to leaks if not addressed properly.

Watch: Applying liquid membrane over fibreglass matting
Before full waterproofing begins, cracks, joints, laps, fixings, and weakened areas are repaired and reinforced.
As demonstrated in the video, this often includes:
Once preparation and reinforcement are complete, multiple layers of the liquid waterproofing system are applied.
The system is built up in stages:
The result is a fully bonded, seamless, and durable waterproof membrane that protects the roof from standing water, weather exposure, and temperature movement.
Liquid-applied flat roof waterproofing systems offer a modern alternative to traditional roofing methods, delivering long-term performance with minimal disruption.
Watch: Why installers prefer this system over traditional fibreglass
Existing roofs can be restored and waterproofed without costly strip-out, significantly extending roof lifespan.
The liquid membrane creates a joint-free surface with no weak points, reducing the risk of future leaks.
Easier to apply than traditional fibreglass, allowing precise, controlled installation with minimal disruption.
Unlike rigid systems that crack over time, the membrane remains flexible, adapting to roof movement and temperature changes.
Designed to withstand rain, UV exposure, temperature extremes, and even permanent standing water without degrading.
By restoring rather than replacing existing roofs, this system delivers durable protection at a fraction of the cost.
Thanks to its exceptional adhesion, flexibility, and durability, this waterproofing system performs reliably where traditional solutions often fail—making it a proven, long-term choice for flat roof protection.
