Most commercial buildings are flat, and the lack of slope is a risk of standing water and infiltrations that add a big stress to the roof and void warranties. Here comes the role of tapered insulation: it has been designed precisely to create artificial roof slopes and eliminate ponding water from the surface of flat roofs.
A tapered roof system can be installed much easier than adding a layer of screed on top, which saves about 25% on roofing costs. It is lightweight, so it can be handled with ease and does not load the structure of the building.
Design is tied to its performance. In most of the cases, Colorado Springs roofing company specialists use polyisocyanurate insulation, which is rigid foam insulation, commonly used in flat roof construction, being compatible with any roof membrane. There are different potential slope designs that can be created, but roofing specialists must consider each building’s layout, the presence of HVAC units, drainage locations, as well as specific concerns each client may have.
Tapered insulation also has superior R-values. The level of insulation is directly responsible for the energy costs for heating & cooling, so adding tapered insulation to your flat roof will allow you to pay less for energy bills.
