Inverted Roof Membrane Assembly (IRMA)

Inverted Roof Membrane Assembly (IRMA) offer superior protection of the roof membrane from foot traffic and mechanical damage.

Inverted Roof systems are also referred to as ‘upside-down’ roof assembly. In an IRMA, the system’s insulation is installed above the waterproofing membrane, instead of below as in a conventional roof assembly. The membrane is further protected by ballast overtop the insulation.

Inverted Roof Membrane Assembly (IRMA) can be constructed with virtually any type of roof membrane, including BUR, modified bitumen, and single-ply systems.
