Roof That Absorbs Least Heat

Cool roofs can be made of a highly reflective type of paint a sheet covering or highly reflective tiles or shingles.

Roof that absorbs least heat.

A cool roof is a roofing product that reflects sunlight and absorbs less heat than traditional roofs. Since black roof shingles absorb the energy from the sun you lose the option to reflect the sunlight to create a cooler attic. When the sunlight strikes a dark rooftop about 15 of it gets reflected back into the sky but most of its energy is absorbed into the roof system in the form of heat. That s why you don t often see darker roofs in warmer climates.

In contrast a dark roof likely raises the temperature inside your home s highest rooms. Shingles with a higher thermal emittance also allow less heat to transfer into a home. A cool roof is one that has been designed to reflect more sunlight and absorb less heat than a standard roof. The roof reflects a portion of the sun s energy.

The roof radiates some of the absorbed heat back into the atmosphere. Owens corning cool roof collection shingles are specially designed to reflect the sun s energy and absorb less heat than standard shingles without limiting your color options.

A cool roof is a roof that has been designed to absorb less heat and reflect more sunlight than a standard roof.

Some roofing materials come in cool roof options and others can be altered with a highly reflective type of paint or coating to absorb less heat. Darker colors absorb more light trapping the heat in the roof and allowing it to flow into your attic and or top of your home. As a result your air conditioner operates more efficiently uses less energy and leads to lower utility bills. Lighter colors are reflective and cause the heat from light rays to bounce off it s surface.

Shingles with a higher solar reflectance allow less heat to transfer into a home. Cool roofs lower roof temperatures on hot sunny days and therefore keep homes cooler inside saving energy by reducing the need for running air conditioning systems. This means that lighter color roofs hold much less heat than darker color roofs. Heavier thicker asphalt shingles can absorb alot of heat and are continously radiating conducting some of it to the sheathing and framing and thereby to the interior.

Metal roofs get hot too but should have substantially less capacity to absorb heat and should cool off faster. If you have a light roof your home absorbs less heat through the roof during summertime.
