WHAT ARE THE BENEFITS OF A COOL ROOF?










































WHAT ARE URBAN HEAT ISLANDS?

Urban Heat Islands have been created over
time here in the United States and around the
world. In Baltimore, Phoenix, Tucson, Washington,
Shanghai, and Tokyo, for example,
scientific data show that July's maximum
temperatures during the last 30 to 80 years
have been steadily increasing at a rate of onehalf
to one degree Fahrenheit every ten years.

HOW DO CITIES
BECOME URBAN HEAT ISLANDS?
Temperatures are higher in cities because:

• There are few trees, shrubs, and other
plants to shade buildings, intercept solar
radiation, and cool the air by “evapotranspiration.”

• Buildings and pavement made of dark
materials absorb the sun’s rays, causing
the temperature of the surfaces and the
air around them to rise.

The heat that is absorbed by your old roof system has to go somewhere; therefore, it is radiated back into the atmosphere causing what is known as the Urban Heat Island. The heat will also be absorbed by a cooler surface, typically the inside of your air-conditioned building. This in turn causes your HVAC to work harder to cool the inside of the building, costing you more in energy consumption.
