Cool roof shingles and tiles.
How cool roofing works.
Cool roof shingles tiles and slate may be coated with special granules to give them better solar reflectance.
Cool roofs can be made of a highly reflective type of paint a sheet covering or highly reflective tiles or shingles.
It is an eco friendly paint which upon application to cementaceous asbestos or ms roofing increases the emissivity of that surface which results in reflection of heat energy.
On top of the rafters your roof has plywood followed by sheathing a material that s designed to protect your home from moisture.
This results in lower absorption of solar heat and a cooler roof.
Today there are many options for roofing underlayment materials rubberized asphalt to organic fiberglass to synthetic.
While the term cool roof is sometimes used to describe any roofing surface that is cooler than a standard rooftop green certification programs such as leed energy star the u s.
Green building council and the department of energy building technology program base their respective cool roof credentials on a roofing material s ability to reflect the sun solar reflectance and release absorbed heat emissivity.
It begins with the rafters and continues on in layers of protection that prevent water and the wind from damaging your home.
Nearly any type of building can benefit from a cool roof but consider the climate and other factors before deciding to install one.
A cool roof is one that has been designed to reflect more sunlight and absorb less heat than a standard roof.
On the other hand cool roofs stay cooler in the sun and transmit less heat into the building.
Thermal emittance ability to cool down by emitting heat that is absorbed.
How your roof works your roof is not just made up of a few shingles.
A cool roof is a roofing system that delivers higher solar reflectance the ability to reflect the visible infrared and ultraviolet wavelengths of the sun reducing heat transfer to the building and higher thermal emittance the ability to radiate absorbed or non reflected solar energy than standard designed roofing products.
Cool roofs are designed to lower the temperature of your home in summer months making you more comfortable and potentially reducing your energy bill.
Cool paint is made of highly reflective type of paint by emissivity aqueous coating based on acrylic resins.
The right underlayment for your roof will keep moisture cold weather and stifling summer air out giving your roof a longer life.
Reflective metal roofing may also cool high slope roofs.
Solar reflectance ability to reflect sunlight.
The coolness of a roof is determined by two properties of roofing materials and their combined effects on temperature.
Whereas darker traditional roofing materials absorb sunlight the reflective surfaces of a cool roof reflect it away.
