Blog 3 energy saving technologies to consider with metal roofs.
How do metal roofs save energy.
As the demand for energy saving building materials increases metal roofs are installed more often.
A study funded by the u s.
Department of energy and conducted by the oak ridge national laboratory shows why metal roofs promote energy conservation in the home.
The secret to metal roofing s energy savings is in its variety of finishes.
Metal roofs can have solar reflective coatings applied which reflect the sun s radiation and are helpful in warmer climates.
In contrast asphalt shingles store and retain more heat in the summer.
Likewise in the summer an air gap prevents the heat of the sun from warming up the attic and the rest of the home.
But how exactly does a metal roof save more energy.
The basic unpainted metal roof will reflect more solar radiation than an asphalt roof which absorbs and holds heat.
