Inverted Roof Membrane Assemblies (IRMA) position the waterproofing membrane directly on the structural deck and protect it with insulation and ballast above. This configuration shields the membrane from thermal cycling, UV exposure, and mechanical damage, significantly extending service life. IRMA systems are commonly used amenity spaces, balconies, terraces, green roofs, and more. The new-construction approach to roofing offers an aesthetic roof assembly with long-term durability, energy efficiency, and robust waterproofing performance.

Roof Waterproofing

Cold fluid-applied roofing systems are efficient, eco-friendly, and cost-effective solutions that protect roof assemblies against leaks, weathering, and long-term deterioration. NaturaSeal solutions cover retrofit roof restoration, inverted roof membrane assemblies (IRMA) for new roofs, and green roof systems, each designed to deliver reliable waterproofing, thermal performance, and protection from environmental exposure. These high-performance systems extend roof lifespan, enhance building efficiency, and support both functional and landscaped rooftop designs.

Roof maintenance coatings offer an effective and efficient way to extend the service life of a structurally sound roof by reinforcing its existing integrity rather than masking underlying issues. When applied to a roof that is still in good condition, these coatings provide a seamless, highly durable protective layer that improves weather resistance, reduces thermal stress, and enhances overall performance. NaturaSeal&rsquo;s PME coatings serve as a strategic investment for roofs that remain fundamentally healthy but would benefit from added protection. By strengthening the substrate, improving energy efficiency, and delaying costly tear-offs, maintenance coatings deliver long-term value while supporting a proactive and sustainable approach to roof management.
