Cool roofs, also referred to as white roofs, have special coatings and colors that reflect sunlight and emit heat more efficiently than traditional roofs, thus keeping them cooler in the sun. Cool roofing technologies can be implemented quickly and at a relatively low cost, making it a fast-growing sector of the building industry.

According to ENERGY STAR®, Americans spend about $40 Billion annually to air condition buildings. Traditional roofs absorb 90% or more of incoming solar energy. The higher the roof temperature, the harder the air conditioning system must work to keep interiors cool.

In contrast, cool roofs can substantially reduce the roof surface temperature – sometimes by up to 100°F - thereby reducing annual air conditioning use by as much as 15%. This helps to reduce energy costs by keeping attics and ducts cooler, improve occupant comfort, cut maintenance costs, and increase the life span of the roof.

When constructing a new roof, or if it's time for your roof to be replaced, consider cool roofing a viable, cost-saving option.
