Cool Roof Systems
07/28/2016

Cotterman & Company is an industry leader of installing cool roof systems. A cool roof is both highly reflective and highly emissive, transferring less heat into the building compared to a dark colored "non-cool roof."
- Cool roofs provide benefits in all climates throughout the United States:
- Cool roofs, with highly reflectivity and emittance, can be 70 degrees cooler or more during hot summer days when compared with traditional roofing materials.
- Cool roof systems save money and energy during peak cooling demand periods - typically mid-days, when electricity demand and costs are highest.
- A cool roof surface can reduce the cost of operating rooftop HVAC units because the units will use cooler air than if mounted on a dark roof surface.
- By keeping moisture out while reflecting ultraviolet (UV) and infrared (IR) radiation, a cool roof can help to protect underlying insulation and the roofing substrate from deterioration.

Last week, after the snow and ice finally cleared here in Dayton, Cotterman & Company Inc. completed a roof evaluation on a large warehouse facility that had recently started experiencing leaks.
As part of the inspection, a date stamp was located on the membrane: DL ’99.
That simple marking told a big story.
