Protected Membrane Roofing (PMR) assemblies have been widely adopted in low-slope commercial buildings since the late 1960s. Also known as the Inverted Roof Membrane Assembly or Upside Down / Inverted Roof, PMR assemblies move the waterproofing membrane from the top of the roof assembly to the surface of the structural deck. This simple design change provides several advantages over conventional roof assemblies that have their waterproof membrane fully exposed at the top surface. For architects, PMR assemblies present many opportunities to create innovative, sustainable, and efficient buildings. The most significant advantage is that PMR assemblies offer superior protection against water penetration, which reduces the likelihood of leaks and extends the lifespan of the roofing system. They also offer enhanced energy efficiency, from the strategic insulation layer placed above the waterproofing membrane. This course will also show how PMR assemblies provide ample opportunities for sustainable design integration. They allow for the creation of green roofs or Blue Roof systems, which provide environmental benefits like rainwater harvesting. With its proven record of reliability, PMR assemblies present a compelling solution for architects seeking innovative, sustainable, and efficient roofing option
