Metal Roof Energy Efficient

A white or light colored metal surface reflects best under testing at about 67 percent reflectivity and even some newly developed cool colors send the rays away source.

Metal roof energy efficient.

Due to their durability and energy efficiency they have significant cost saving potential. Unpainted metals are typically good solar reflectors but poor thermal emitters so they rarely satisfy low slope cool roof requirements. This makes it a versatile and appealing product. Alternatively you can apply cool reflective coatings.

How they can be made cool. Energy star certified roof products can help reduce the amount of air conditioning needed in buildings and can reduce peak cooling demand by 10 15 percent. A high quality metal roof can save homeowners up to 40 in energy costs. Reflectivity requirements differ for low slope and steep slope roofs.

Florida solar energy center. Certified roof products reflect more of the sun s rays which can lower roof surface temperature by up to 100f decreasing the amount of heat transferred into your home. Metal roofs also have lower concentrations of bacteria compared to other materials especially when coated in an anti microbial paint system that reduces the amount of potential contaminants that may grow on the roof. Painting a metal roof can increase its solar reflectance and thermal emittance allowing it to achieve cool roof status.

It comes in a variety of formats and designs including shingles standing seam wooden shake and tile. To achieve the most energy efficiency and to make your home greener you can also consider installing photovoltaic solar panels on top of your standing seam metal roof. The secret to metal roofing s energy savings is in its variety of finishes. Metal roofing types metal is light energy efficient and durable.

The ability of the roof to radiate the sun s heat up and away. The popularity of metal roofs has soared in recent years because of their durability energy efficiency and environmental performance. And while asphalt tiles don t have the power of a magnifying glass they do intensify the heat from the sun by holding it long after the sun itself has called it a day. Modern energy efficient metal roofing acts as a giant mirror of sorts by reflecting the heat and energy up into the air.

When evaluating a roofing material s energy efficiency also known as thermal performance there are three terms to familiarize yourself with. These roofs can last for 40 to 70 years and are recyclable at the end of their useful life. Metal roofing is a prime choice for this energy efficient and eco friendly process because of its durability. Metal is one of the most energy efficient roofing materials available and can save your home up to 40 in energy costs and provide excellent insulation during the winter.
