Henry cool roof coatings will
save money, energy and your roof
FACT:
Without a cool roof coating, a roof will absorb nearly all of
the sun’s heat and UV radiation. This causes air conditioning
systems to work harder, driving energy costs higher. Roofing
surfaces deteriorate faster, leading to costly repairs, or even
costlier replacement.
With a Henry ENERGY STAR-rated cool roof coating, a roof will
reflect most of the sun’s heat and UV rays, reducing energy
bills, extending roof service life, and improving occupant
comfort. ENERGY STAR qualified cool roof products can:
• Reduce energy bills by up to 50%*
• Lower roof surface temperatures by up to 100°F*
• Reect over 88% of the sun’s heat and UV rays
• Help reduce the amount of air conditioning required

Actual results will vary depending on factors such
as climate zone and building design parameters.
Actual photos tell the story: Henry’s Enviro-White
™
with DPR technology keeps roofs cooler.
Thanks to special Dirt Pick-Up Resistant (DPR) technology, Henry’s 687 Enviro-White
™
outperforms ordinary roofs, lowering
temperatures dramatically to help building and home owners across the country cut energy costs. The photos below, all taken at the
same time in Phoenix, Arizona, demonstrate just how dramatic the temperature difference can be. The Henry cool roof white reflective
coating (top left) is 49°F cooler than the white, uncoated roof (top right). And the Henry roof is a full 68°F cooler than the black roof!
Uncoated white granulated roof = 152°F
White coated granulated roof = 103°F
Uncoated black granulated roof = 171°F
Uncoated tan granulated roof = 163°F
