Roofing Contractor | How Do the Metal Roofs Keep the Buildings Cool?
Most people misinterpret the cooling properties of metal roofs considering that its thermal conductivity and electrical properties, makes its surface hot. However, that isn’t the case — the cool and energy efficient characteristics of metal roof that you are looking for are dependent on the quality of construction material and the aptitude of the roofing contractor. Here is how the metal roofs keep the buildings cool:
- Low Thermal Mass
Metal roofs reflect the light falling upon it because of low thermal mass. This property prevents them from absorbing light, meaning that when the external temperature cools, they also cool down. If there is additional reflective coatings applied by the roofing contractor the metal roof also have the tendency to re-emit the heat. You will realize that the attics are much cooler in the warm summer days and you will be able to notice the change in the cooling system’s efficiency.
- Low Maintenance
Conventional roofing materials experience severe damages after a storm or hurricane — resulting in extensive roof repairs. Sometime even the lifetime also declines, forcing homeowners to have roof replacements earlier than the lifetime of the material. In contrast, metal roofing has warranties that extend up till 40 years or more and have lifetime greater than 50 years.
- Not Just Cooler— Metal Roofs Are Also Greener
Because metal roofs are mostly constructed with 98% recycled aluminum materials, they are considered a sustainable option. The fact that they are pre-fabricated also limits the transportation costs. Just in case the roof has to be dismantled, it can again be recycled for a new construction, making them greener than other roofing materials.
