Cool Metal Roof

There was much interest in the industry when cool metal roof systems were first launched, chiefly in terms of energy savings for the consumer. Sturdy, and wind and fire resistant, metal roofing products provide a low-cost life cycle. Cool metal roofing was first developed because of the obvious need for “green” products. Other roofing materials pale in comparison to cool metal roofing, especially when it comes to energy savings. Here’s how:
 

The biggest drawback of this material is it’s heaviness: it requires special structuring, and it’s costly to ship. In comparison, metal roof systems are also among the lowest weight roofing products available, since they usually vary from 40 to 135 pounds per square foot. A cool metal roof also reflects solar energy rather than absorbing it, allowing the roof surface to remain cooler, which means less heat is transferred into the building.
 

Cool metal roof products are not subject to the deterioration experienced by organic materials like wood when they are exposed to the weather cycle. Most metal roof systems have also been tested to meet Class A, B and C fire ratings. The architectural appeal of a cool metal roof, along with its wide range of profiles, textures and colors and long-term durability make it popular for residential projects.
 

The widespread use of energy-absorbing, dark building materials such as asphalt, together with a shortage of plant life, generates a microclimate where ambient temperatures are higher than in the nearby areas. A cool metal roof is one way to alleviate this urban heat island effect. These roofs reduce ambient air temperatures, since they have higher reflectance and lower surface temperatures. Homeowners experience a striking difference in home energy consumption with cool metal roofs as compared with other roofing materials that merely absorb solar radiation and move the heat straight into the house
