Durability, protection against chemical exposure, cool roof requirements, and potential savings on cooling costs can make roofing choices feel overwhelming. At Siplast, we face the same conundrums you face when we re-roof one of our own warehouses, plants, and offices. This is a project that shows how roofs can adapt to modern roofing demands.
In 2023, Siplast decided to use a two-ply hybrid re-cover roofing system that offered a unique combination of reliability and performance for one of our warehouses. The existing Paradiene® 20/30 roofing system was in generally good condition overall, but needed some minor repairs prior to reroofing to help ensure water tightness and to prepare the upcoming reroofing project's updated performance requirements. The re-cover roofing system consisted of a gypsum-based recovery board, a self-adhesive base ply, and a fleece-back PVC KEE (Parasolo® KEE) adhered with low-rise foam adhesive.
A recovery board provides a solid, smooth substrate for the two-ply hybrid membrane and a proper surface to adhere to. A self-adhesive base ply makes for an efficient application and allows phased construction due to its weathertightness. The PVC KEE membrane offers enhanced durability and protection against chemical exposure and algae growth, as well as increased roof reflectivity.
But why choose a hybrid roofing system in the first place? Temperature control (i.e., high reflectivity), durability, performance enhancements, and service life are key factors. Of course, an SA base ply (e.g., Paradiene® 20 SA) with a PVC KEE membrane (e.g., Parasolo® KEE) is just one of many possible hybrid membrane configurations. Multiple base plies, varying types of base plies, numerous application methods, as well as alternate single-ply membrane types can be used.
