The Truth About Metal Roofing in Hot Weather

As the temperatures begin to rise at the start of the summer season, most homeowners understandably worry about keeping the heat out of their homes. But, even though you may have your central air serviced, your windows sealed, and your walls insulated, there is no physical part of a house more integral to keeping you and your family cool this summer than your roof.

Metal has been proven to be the most energy-efficient roofing material. Sadly, there are still many misconceptions among homeowners about the efficacy of metal roofs with many claiming that the material is too reflective and less efficient than traditional materials. Fortunately, the Green Knight metal roof installation pros in Williamson County, TX, can debunk the metal myths once and for all!

Myth #1: Blinded By the Light

Frequently when we think about metal, the reflective qualities of some metals come to mind (like shiny stainless steel or car-tops on the highway at noon). Many homeowners shy away from installing metal roofing because they believe that their roofs will provide a highly-reflective surface for sunlight to blind passersby, but that could not be further from the truth.

The Sun’s Energy

To better understand why this is a myth, we must first take a look at the distribution of the sun’s energy in three major categories:

  • Infrared: Non-visible rays that produce the majority of heat.
  • Ultraviolet (UV): Non-visible rays that are not felt, but can damage roofing materials.
  • Visible: Rays that we can see, as the name suggests.

It is true that basic, unpainted metal roofing does reflect more solar radiation than traditional materials; however, with the many metal styles, finishes, colors, and coatings from which to choose, low-glare metal roofs end up reflecting mostly infrared and UV rays, which are not visible and cause the most heat gain and exterior damage. Even dark metal roofs can emit as much as 85 percent of the heat generated by the sun without burning the retinae of your neighbors.

Myth #2: Metal Can’t Beat the Heat

Due to inadequate materials and installation jobs, roofs are frequently the least efficient part of a home. Luckily, the experienced technicians at Green Knight Metal Roofing can scrap this myth with ease. Watch the video below for more information on how “cool” metal roofs can be.
