Roofing membranes within a roof assembly are generally the only barrier to keep the elements out. Standard building cladding design recognizes that well-performing walls consist of layers of materials (zones) to resist wind, heat, rain, etc., to achieve the rain screen principle in wall cladding. This dual-barrier design can be applied to roofs. Protected membrane roof (PMR) assemblies can have superior performance over conventional roofs since the moisture-resistant insulation protects the primary roofing membrane from the environment. Dual-barrier design can be implemented to help reduce negative effects of water diffusing into the insulation or reducing the thermal performance by flowing underneath. Typical PMRs can be easily upgraded by the placement of a properly selected vapour-permeable drainage layer above the insulation.

Objectives

  • Understand when to utilize protected membrane roof assemblies to meet specific design requirements.
  • Decipher what systems and products to consider using.
  • Determine how to implement and ways to assess the benefits of protected membrane roof assemblies.

Interesting approach to rehabilitating PMR roof assemblies.
