Cool Roofing Defined
The term cool roofing refers to the ability to minimize heat gain through the roof surface. It can be described by two terms: solar reflectance and thermal emittance. The combination of those properties determines the surface temperature of a roof and its ability to act cool.

Solar Reflectivity
Solar Reflectivity is a measure of a material's ability to reflect sunlight. This characteristic of metal roofing is the most important in terms of energy savings. Cool metal roofing reflects much of the sun's rays, making the surface of the metal much cooler than material with a lower solar reflectance rating.

Emissivity is the ability of a material to release absorbed heat. A low emissivity rating means the material will be hot to the touch (it doesn't release the heat), while material with a higher emissivity rating will be cooler to the touch.

         What are the Benefits of Cool Roofing?
Savings on Energy Bills
    Cool roofing owners have reported annual energy savings up to 40%. Metal roofing solar reflectance and thermal emittance capabilities can reduce air conditioning and heating costs. Some insurance companies offer discounts to customers for using a qualified metal roof.

Environmentally Friendly - Green Product
    Metal roofing's durability can virtually eliminate the need to use future raw materials to produce roofing. Metal will outlast most other roofing products. Conventional roofing shingles have much shorter lives and use oil-based products as their primary raw material. Most metal roofs have recyled content ranging from 25% to 95%. Metal also has the added benefit of being 100% recyclable if it is ever removed in the future.

       What Martin's Steel Roofing Provides:
    Our painted metal panels are available with limited 40 year paint warranties which should last 2-3 times longer than traditional asphalt shingles.
    We also carry a variety of colors that meet ENERGY STAR requirements in reflectivity and emissivity values.
