Yes. An inverted roof can be just as watertight as a traditional roofing system. The order of the system’s components is simply reversed: the waterproofing membrane is installed directly on the roof deck, with the insulation placed above it.
This design protects the waterproofing membrane from ultraviolet radiation, temperature fluctuations, and weather exposure. Inverted roofs offer several advantages, including potential savings on installation and project materials.
However, repairs can be more complex because the materials above the membrane must be removed before it can be accessed. Before choosing this type of roofing system, consult an LK Toitures expert.
