Is A Metal Roof Hotter

Or course color isn t the only aspect of your roof that affects home temperature.

Is a metal roof hotter. Yes metal roofs are cooler than shingle s and work to keep the hot air out so that your air conditioner doesn t have to work overtime. Based on my personal experience with both asphalt shingle and metal roofs a metal roof is hotter to walk on. They don t collect and absorb radiant heat to a significant degree as do some forms of roofing material. That s why sentry roof always tries to use metal roofing that s been coated with basf paint as part of the manufacturing process it helps cut down on the surface heat.

However there is a layer of insulation at least mine does between the metal panels and the existing roof deck which reduces heat transfer to the attic. Though you ll get more life out of a metal roof you ll pay the price at the time of installation. Once the sun stops shining on a metal roof it quickly reverts to the same temperature as the surrounding air. This quality means even tan asphalt shingles may welcome more heat into your home than a dark brown metal roof.

Metal roofs generally can run from 120 to 900 per 100. Metal roofs do not have substantial thermal mass. We can paint the roof after it s installed but installing pre painted is best. It can be difficult to understand the cooling properties of a metal roof.

Still slight increases in temperature are possible because of the nature of the color. Shingle roofs are cheaper up front. Metal roofs also get hot. Unlike black tar shingles or roll roofing however the metal is less insulating and doesn t retain as much heat from the absorption.

The lightest roof available is metal so it cools quickest. This is especially pronounced in aging roofs. With heavier materials like slate or concrete their mass means they will retain heat much longer. The roofing material also affects how reflective your roof is.

Metal roofing dissipates heat and swiftly cools down as soon as the sun is hidden by clouds or a cool wind passes over its surface. This is because high temperatures and intense sun are especially damaging to roofing materials prompting homeowners to seek out more durable lasting and energy efficient options. For example asphalt shingles are less reflective than metal or rubber roofing materials.
