BIM modelling for mechanically fixed roof systems

With a mechanically attached roof system, the EPDM roof covering is attached to the roof construction with a fastener that goes through the insulation layer and into the substrate. Because the fastener goes through the insulation layer, the entire roof package is attached to the substrate. A mechanically attached roof system has been increasingly used in the UK in recent years. In addition to a simple mounting method, a mechanically attached roof has high wind uplift resistance and is easy to separate during renovation.

Our RESITRIX® and HERTALAN® EPDM waterproofing membranes are both suitable for use as part of a mechanically fixed flat roofing system.


RESITRIX® is the only flat roof membrane manufactured using a unique combination of high-quality polymer-modified bitumen and synthetic rubber EPDM. A successful and advantageous combination because thanks to the polymer bitumen layer on the underside, the material can be used over almost any surface. The re-inforced EPDM core ensures a long life expectancy of more than 50 years (SKZ study).

    HERTALAN® EPDM Membranes

    HERTALAN® EPDM systems offer many advantages over traditional flat roofing systems. EPDM is the synthetic variant of a natural rubber type and therefore has unique product properties. This makes EPDM ideally suited for sealing flat and slightly sloping roofs.

    ✓ Proven life expectancy of more than 50 years
    ✓ Suitable for many different types of roof structures
    ✓ Environmentally friendly product
