Since metal roofs reflect heat away from buildings, they are considered one of the most energy efficient roofing materials on the market. A high-quality metal roof can save homeowners up to 40% in energy costs. Metal roofs do not heat a house more than other types of roofing materials. Because metal roofs have a low thermal mass, they reflect light and heat instead of absorbing it like asphalt shingles.
This means that instead of heating your home during the summer months, metal roofs help keep you cool, increasing your home's energy efficiency. While it's true that a metal roof will absorb heat when exposed directly to the sun, the same goes for any roof covering material. A dark-colored roof on asphalt, ceramic, slate, or any other material will absorb heat at approximately the same rate. Using the same color in different materials is unlikely to result in a significant temperature difference at the top of the roof.
This is a rumor that is obviously false. The truth is that metal roofs don't increase the internal temperature of a home and can even help regulate the temperature of a home by making it cooler in the summer months. A metal roof is able to balance the temperature inside your home because it is very reflective. Metal has a low thermal mass, which allows it to reflect light and heat rather than absorb it.
This means that most, if the sunlight the material is exposed to is deflected, it decreases heat transfer to your home. Once the temperature drops outside, the metal material will also be much cooler. Metal roofs are available in a variety of finishes. The added pigmentation can help emit up to ninety percent of the heat that is absorbed.
Whether you're putting a roof on a new home or your existing roof requires a total renovation, there are many materials available. But no matter what style of roof you have, metal roofs can be an attractive option due to their longevity, minimal maintenance, and energy efficiency. Material options include steel (galvanized, galvalume, or weather resistant), aluminum, copper, zinc, and tin. Product types are vertical joints, preformed panels and granular coated panels.
Style options allow you to have the look of shingles, slate, tile, milkshake, or vertical panels. Ensure your metal roofing product is tested, labeled, and listed with a testing organization, such as UL, FM Approvals, or Intertek, to meet rigorous wind, fire, and impact rating requirements. Also remember that installation may vary based on geographical location, manufacturer guidelines and, as a result of local building code requirements. No roofing system will create a cool home in the summer, but most roofs help keep out the heat that comes from direct sunlight.
Infrared roof inspections and energy audits can help you find weak spots in your roof insulation, where heat transfer looks different from the rest of the roof. One of the main concerns many homeowners have when considering metal roofing is the internal temperature of their home, particularly that of the attic. Metal roofs are a great option for homeowners looking to improve their home's energy efficiency. While the color and material of the roof will certainly affect the amount of heat collected by the roof, the biggest factor contributing to that heat being conducted to a room below is the type of construction between the ceiling and the space occupied below.
If the roof is well constructed, ventilated, and the attic has the right amount of insulation, the heat that the roof absorbs will not have a major effect on the temperature inside your home. Yes, metal roofs are cooler than shingles and work to keep warm air out so the air conditioner doesn't have to work overtime. So which roof is most energy efficient in warmer climates? By far, it's a metal roof, but how does it work?. In an exceptionally hot area like Alabama, homeowners can go one step further by choosing to use metal products that are built with integral air space that separates the back of the metal panel and the subfloor.
Now you know the truth: metal roofs are really good for keeping your home cooler, as they reflect the sun's rays. Both metal and asphalt roofs do the job when it comes to protecting a building, but they really separate when it comes to durability, energy efficiency and cost. . .
