Asbestos Roof Repair & Encapsulation Safe, Cost-Effective, Long-Lasting

Many older buildings from domestic garages to commercial shopping centres and factories still have asbestos cement sheet roofs. While asbestos removal or over-cladding are often assumed to be the only repair options, there is a safer, faster, and more cost-effective alternative: repair and encapsulation.

At Dublin Protective Coatings, we specialise in asbestos roof repair and encapsulation, extending roof life by decades without disturbing the asbestos fibres. Our solutions minimise disruption, improve safety, and save you time and money compared to removal.

Our Asbestos Roof Repair Services

1.

Spot Repair of Defects, Overlaps & Rooflights

We repair visible problem areas using hand-applied LAVA 20 with reinforcing tape for a quick, targeted fix. This method is ideal for localised leaks and includes one follow-up visit after completion. Additional visits may be required.

2.

Full Asbestos Roof Waterproofing & Encapsulation

For maximum protection, we apply a seamless closed-cell polyurethane foam blanket across the entire roof, topped with 2mm of polyurea coating and followed by UV stable top coat. This creates a watertight, weatherproof, and long-lasting barrier without disturbing the asbestos.

Preparation Stage

Safe Cleaning & Preparation Process

Before encapsulation, the roof must be clean and dry. To ensure safety and compliance, we:

  • Use robotic cleaning equipment to avoid close contact
  • Filter contaminated water to 7 microns before disposal
  • Allow surfaces to dry fully before coating

Encapsulation is the safer, more cost-effective solution approved by the Health & Safety Authority. Removal involves breaking asbestos sheets, creating dangerous dust that poses health risks to workers and the surrounding area. Our encapsulation system costs 50% less than removal, takes only instead of , and most importantly, allows your business to remain operational throughout the process. The asbestos remains safely sealed, eliminating any risk of fibre release whilst maintaining its fire-resistant properties.

No, you won't need to close your facility at all. This is one of the biggest advantages of our encapsulation system. All work is conducted entirely on the roof exterior, meaning your interior operations continue completely unaffected. There's no production downtime, no revenue loss, and no need to relocate inventory or employees. We've completed numerous projects where factories have maintained full production throughout our entire installation process.

Our polyurea system comes with a warranty and has a proven life expectancy of . The technology was developed in the , and original applications are still performing perfectly on roofs today. Even after decades, the system can be simply recoated to extend its life another . This isn't a temporary fix—it's a permanent solution that's actually more durable than traditional roofing materials.

Our system consists of three protective layers. First, we apply a specialised cleaning treatment without disturbing the asbestos. Then, we spray a 1-inch layer of closed-cell polyurethane foam that expands to fill all gaps, joints, and imperfections, creating a seamless waterproof barrier. Finally, we apply two coats of Lava 20 polyurea resin that cures instantly, creating a super hard yet flexible surface. This combination provides complete waterproofing, thermal insulation, and structural reinforcement—all whilst safely encapsulating the asbestos.

We can complete 1,000 square metres in under , with our team typically covering 800 square metres per day once application begins. This is 65-75% faster than traditional removal or re-roofing methods. The polyurea cures instantly—within of application—providing immediate waterproofing. We can work a year, even in wet weather conditions, so there are no weather-related delays unlike traditional roofing methods.

Yes, absolutely. The Health & Safety Authority directly instructed us on this approved methodology. Spray encapsulation is the only legally approved method for treating asbestos roofs in-situ. Our system is BBA approved with the highest European fire rating (B Roof T4), and we require independent consultant verification before commencing any project. All our workers hold asbestos awareness certifications, and we maintain full compliance with all health and safety regulations. This isn't just legal—it's the recommended approach by regulatory authorities.

Our encapsulation system costs approximately 50% less than complete asbestos removal and replacement. You save on disposal fees (which require transport to other European countries), avoid business closure costs, eliminate temporary roofing expenses, and prevent weeks of lost production. Additionally, the included insulation upgrade reduces your heating and cooling costs by 20-30%, providing ongoing savings. The system essentially pays for itself through energy savings and avoided closure costs. We can provide a preliminary quote using just your Eircode and Google Maps—no site visit required initially.

No, undisturbed asbestos produces absolutely no dust or fibres. Asbestos is only harmful when it's broken or disturbed, releasing fibres into the air. Our encapsulation system permanently seals the asbestos from above, preventing any possibility of fibre release. If additional peace of mind is required, we can also apply closed-cell foam from underneath, creating double protection that exceeds all safety requirements. The key fact is: intact, sealed asbestos poses zero health risk to anyone in the building.
