High Albedo Roof Shingles

Reflective surfaces are a form of geoengineering.

High albedo roof shingles.

2 is a photo graph showing a black asphalt shingle roof that was coated with a high albedo coating. The most well known type of reflective surface is the cool roof. Contact your upper deck as close to a lot of rest while experienced company that will keeps the roofing materials. Shingle roofs consist of overlapping panels made from a variety of materials such as fiberglass asphalt wood polymers or metals.

Reflective surfaces can deliver high solar reflectance the ability to reflect the visible infrared and ultraviolet wavelengths of the sun reducing heat transfer to the surface and high thermal emittance the ability to radiate absorbed or non reflected solar energy. Aloe s protection you must choose the quality of your roof deck roofing material. Roof venting has a far lower effect on peak shingle temps than the sri and on medium and high pitch roofs greater than 2 12 pitch under cool roof terminology convection cooling on the exterior provides an order of magnitude more shingle cooling than any scheme for ventilation under the roof deck can. Solar roof shingles are made from a material that can withstand high speed hail impact and very high winds.

Malarkey is greencircle certified. Buy cool asphalt shingles which use specially coated granules that provide better solar reflectance. Coolness is measured by two properties solar reflectance sr or reflectivity and thermal emittance emissivity or a combination of the two called the solar reflectance index sri. It came back high albedo shingles again because fibers to go airborne.

How they can be made cool. Cool roofs can also be referred to as highly reflective roofs and high albedo roofs. Coating existing asphalt shingles to make them cool however is not normally recommended or approved by shingle manufacturers. These asphalt shingles are manufactured with.

In california where many low rise residential homes are subject to the requirements of title 24 cool roof shingles have become a major trend in residential roofing. Where the roof was not coated the shingles cracked and shrank partly because of thermal expansion and contraction and partly because of the uv blocking capabilities of the coating which protected the asphalt component of the shingle from. As one would expect albedo roofs are formulated with special high eminence materials that keep project a high level of thermal energy back into the atmosphere. Solar roof shingles offer some interesting benefits and are now available in a variety of styles to match the look of asphalt slate and clay tile.
