How much cooler is a house with metal roof?
Metal roofs, on the other hand, reflect the sun’s heat away from a building, leading to energy savings of about 50 percent, and they can be about 100 degrees cooler on the surface than traditional asphalt roofs [source: MRCA].
Do metal roofs really save cooling power?
Energy efficiency. Metal roofs reflect the suns UV and infrared light rays that contribute to roof surface radiant heat, which can result in a 10-25\% reduction in cooling costs.
Is metal roofing cooler than shingles?
No, metal roofs are not hotter than dark shingle roofs made from asphalt or other standard materials such as slate, for example. Additionally, most metal roofs are treated with Energy Star finishes which, when coupled with paler colors, can result in surface temperatures up to 50 degrees cooler than shingles.
Does a metal roof make your house colder in winter?
A metal roof acts as an insulator and it naturally reflects the sun’s UV radiation. This will keep you home cooler in the summer and warmer in the winter.
How do you cool down a metal roof?
They may soon have another option: paint made of glass. Scientists have created a glass paint that can bounce sunlight off metal roofs and keep them at air temperature. This is no minor feat. The sun can heat metal surfaces so much that playground slides or stadium bleachers can become too hot to use.
How does a metal roof keep a house cool?
Rather than absorbing heat like asphalt shingles, a metal roof is design to reflect sunlight. The roof stays cooler, and no extra heat enters the home. Added pigmentation can help to re-emit up to 90\% of heat that is absorbed into the home. In urban areas, this can reduce air temperatures by as much has 12 degrees Fahrenheit.
Is metal roofing cooler than shingle roofing?
Metal is much cooler than a shingle roofing system. Regardless of the type of roofing material you decide to install over your home, attic ventilation and roof construction are important factors that can determine how well your home balances temperature.
What are the benefits of a metal roof?
A metal roof is able to balance the temperature inside of 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. That means that the majority if the sunlight that the material is exposed to gets deflected away decreasing the heat transfer into your home.
Are cool roofs worth it in cold climates?
In cool/cold climates (US zone 5 and higher) the net annual benefit of cool roof strategies to buildings accrue only to higher density construction or on low-angle & flat roofs, single-family residential.
