Americans spend about $40 billion annually to air condition buildings - sixth of all electricity generated in this country. An efficient roof can save up to 40% of your cooling costs in summer and can reduce urban air temperatures by as much as 12 degrees!
When replacing your roof, using reflective materials such as "white painted metal" can have a dramatic effect on your energy costs.
ENERGY STAR qualified roof products reflect more of the sun's rays. This can lower roof surface temperature by up to 100 degrees, decreasing the amount of heat transferred into a building.
Ballasted Roof Systems
Ballasted roofing systems are fairly common and consist of a membrane that is usually loose laid on the roof deck and held in place by the weight of a natural stone or precast concrete pavers. The weight of the stone or pavers employs the force of gravity to hold the roof membrane in place and counter the uplift forces of wind.
A green roof, or rooftop garden, is a vegetative layer grown on a rooftop. Green roofs provide shade and remove heat from the air through evapotranspiration, reducing temperatures of the roof surface and the surrounding air. Green roofs absorb heat and act as insulators for buildings, reducing energy needed to provide cooling and heating.
More and more, homeowners are seeking out energy-saving building materials for their renovations and new homes, products that not only secure and improve structures but also provide long-term cost-cutting on energy bills while promoting environmental and economic sustainability in the greater community.
Among the array of possible upgrades, “cool metal roofing” easily answers this consumer demand offering a solid, attractive roofing solution available in multiple colors, textures, and profiles, for steep-slope and low-slope applications, that can save your household up to 40% of its annual energy costs, depending on your geographical region.
