Roofing & Insulation and along with ERSystems has
long promoted that "Bright is Right" pertaining to roof surfaces.
Bright, highly reflective materials produce cooler roofs which
reduce energy costs, urban air pollution, and help extend the
longevity of the roof system.
The Lawrence Berkeley "Heat lsland Project" studies have proven
that a roof with a high solar absorptive surface (Black EPDM,
Asphalt BUR, Modified Bitumen) exhibits temperatures 75°-100°
F higher than ambient temperature, while a highly reflective roof
is only 15°-25° F higher than ambient temperature. Check out "Cool
Roofs and Energy Conservation" Spray Foam 2001
Pella Roofing & Insulation which uses ERSystems
complete line of highly reflective elastomeric coatings and single-ply
roofing membranes for Restoring metal roofs, dark single-ply roofing
membranes, polyurethane foam, and smooth surfaced built-up and
modified bitumen roofs. In the process of Restoring we can also
Preserve the roof while saving energy, and protecting the environment.
It has been observed that air temperatures in many cities are
5°-12° F higher than in surrounding suburban areas. This effect
is primarily attributed to black roofs, dark pavement, and loss
of shade trees. According to the U.S. Department of Energy this
could potentially be responsible for about 20% of energy costs
associated with air conditioning. This 20% is estimated to cost
building owners approximately 4 billion dollars annually. This
excessive urban heat also contributes significantly to the rate
and quantity of smog formation in the cities. The same studies
indicate that much of this energy could be saved and smog levels
reduced by turning hot, heat absorbing black roofs white with
highly reflective elastomeric coatings or white membranes.
