Energy-efficient roofing systems are becoming increasingly common. An energy-efficient roof can enhance your home in many ways, from reducing your monthly energy bills to helping you live more sustainably.
Today, ABM Services and Renovations Inc. discusses how energy-efficient roofs work.
Energy Efficiency in a Nutshell
A roof that is not energy-efficient will not do much to prevent heat from the sun from entering your home. As your roof heats up, this heat will spread into your attic, raising your home’s internal temperature.
Energy-efficient roofs are designed to reduce the heat absorbed by your roof. With less heat entering your attic, and, by extension, your interior, your HVAC system won’t need to work as hard to regulate your home’s temperature. Additionally, an energy efficient roof could even minimize the need for roof repair because your attic won’t suffer damage from skyrocketing temperatures in the summer.
Roofs built with solar reflectance reflect the sun’s energy away from the home rather than absorbing it. Reflectance is measured from 0 to 1, the latter being the highest level of reflectivity. Different “cool roofing” materials have a different solar reflectance levels, so be sure to do your research.
One thing to be aware of is that the reflectivity level of cool roofs can gradually change. Dirt and deterioration can slowly chip away at the reflectiveness of your roof. When that happens, call us so we can provide you with a roof replacement.
Emittance is the roofing material’s ability to remove heat rather than retain it. Shedding the excess heat keeps the material cool, which also helps keep your home cool. A roofing material’s emittance is also scaled from 0 to 1, with 1 being the highest level. When you’re looking for a new, energy-efficient roof, choose a for product that features strong thermal emittance.
