What Can (And Should) Go Under Roofing Membranes?

A flat or low slope roof assembly consists of several components that need to work together efficiently and consistently to offer a long-term, sustainable solution. While the roofing membrane is often the top and therefore most visible layer, what lies under it has a significant impact on the overall roof performance. Choosing the adequate and most sustainable materials (and ensuring their proper installation) is what makes a roof stand the test of time and be ready for the challenges of the future.
