Commercial flat roofs are typically more cost effective because of the flat design. They cover fewer square feet and thus require less materials to complete the project. They are easier and quicker to install, which can translate to a significant savings for the building owner on both materials and labor. Owners have many types of flat roofing materials and membranes to choose from – rubber rolled roofing, EPDM, PVC, TPO, bitumen, modified bitumen and built-up roofing. While there are many different color choices to choose from with roofing membranes, however many building owners choose to stick with white. This can help reduce energy waste from cooling costs due to it’s reflective properties. There are also additional benefits some don’t consider. For instance, air conditioners can be moved from the ground to the roof and solar panels and satellite dishes are easier to install on flat roofs than on pitched ones. Moving these appliances to the roof also makes them less noticeable. Maintenance and drain cleaning is easier on flat roofs since workmen can walk easily and safely, regardless of weather conditions.
