Are you in the market for a “cool” metal roof? And by cool, we don’t mean hip or with it in the vernacular sense of the word. We’re talking about roofs that are literally cool, temperature-wise. Well, there is such a thing, and it all comes from the reflectivity of metal materials used to make what is known as cool roofs.
What Makes Roofs Cool?
Cool metal roofs provide excellent energy efficiency due to their high solar reflectivity. This, of course, translates into lower utility bills for homeowners living in houses equipped with this type of roof. This reflectivity of metal materials used to construct cool roofs is measured by albedos and is expressed in percentages.
