It Came from Hail
“The roof is becoming a more complex, challenging, and important component of any number of buildings, but especially so for schools and universities. The current economic climate, the growing presence of energy producing systems (solar panels or wind turbines), the… Read More
Energy Efficient Roofs
The issue is even more simple than black and white. The days when heating and cooling costs were a relatively insignificant item on a school’s budget are long gone. The price of oil, natural gas, and coal are high, extremely… Read More
Is Ballast Green?
The small, common stones used as roof ballast possess few individual attributes worthy of extensive examination. But the combined effect of these small stones has been gigantic within the roofing industry.

SPRI-ORNL Study Shows Ballast and Paver Systems Save as Much as a Cool Roof
SPRI, the association representing sheet membrane and component suppliers to the commercial roofing industry, has released a final report on a joint study with the Department of Energy, entitled: Evaluating the Energy Performance of Ballasted Roof Systems.
New Ways of Defining Cool Roofs
Currently, cool roofs comply with the U.S Environmental Protection Agency’s (EPA) ENERGY STAR@ roofing products standards. In addition, U.S. states (such as California, through its Title 24 Energy Code [CEC]) prescribe cool roofs as part of the base case building… Read More
Life Cycle Assessment and the LEED Green Building Rating System
“LCA is a better measure of a products “cradle to grave” and true long term economic and environmental than traditional Life Cycle Costing (LCC).”
EPDM Group Champions Recycling
With energy savings and sustainability becoming crucial components of a modern roof system, the ability to recycle roofing products is growing in importance. During the past 18 months, the EPDM (ethylene propylene diene monomer) Roofing Association (ERA) has been conducting… Read More
Evaluating the Energy Performance of Ballasted Roof Systems
It is well known that the mass of a ballasted roof can reduce peak roof temperatures and delay the heat flow into a building. Although ballasted roofs perform these “cool” functions, they do not meet the traditional requirement of high… Read More
