Which Is More Energy Efficient Metal Roof Or Shingle

At the highest rank of energy efficient homes stands the passive house institutes certification.

Which is more energy efficient metal roof or shingle.

These roofs can last for 40 to 70 years and are recyclable at the end of their useful life. 1 cool your roof cool roofs are lighter in color than traditional black asphalt or dark wood shingles and save energy by reflecting light and heat away rather than absorbing them. Standard or dark roofs can reach temperatures of 150 f or more in the summer sun. Due to their durability and energy efficiency they have significant cost saving potential.

Such a roof can be reasonably expected to be some 50 to 60 degrees cooler than a dark color asphalt shingles roof. The popularity of metal roofs has soared in recent years because of their durability energy efficiency and environmental performance. Energy star certified roof products can help reduce the amount of air conditioning needed in buildings and can reduce peak cooling demand by 10 15 percent. In fact a high end kynar 500 white metal roof is energy star rated and classified as a cool roof by the cool roof rating council.

Tile is renewable and energy efficient like. Due to metal roofing s incredibly efficient solar reflectance and thermal emittance metal is the ideal roofing material for the construction of a net zero energy home. The roof of a building is exposed to the sun more than any other part of the structure making the roofing material a critical factor when it comes to energy efficiency. Shingle roofs are cheaper up front.

A cool roof under the same conditions could stay more than 50 f cooler and save energy and money by using less air conditioning. Energy star certified roof products reflect more of the sun s rays. Using a sealant to repair a leak is not a long term fix and it may be more efficient to replace individual shingles. Homeadvisor s metal roof vs shingles guide compares pros cons differences and costs of metal shingle or panel roofing versus asphalt shingle roofs.

This can lower roof surface temperature by up to 50f decreasing the amount of heat transferred into a building. Modern energy efficient metal roofing acts as a giant mirror of sorts by reflecting the heat and energy up into the air. A white or light colored metal surface reflects best under testing at about 67 percent reflectivity and even some newly developed cool colors send the rays away source. Metal roofs generally can run from 120 to 900 per 100.

Cool roofs can be made of a highly reflective type of paint a sheet covering or highly reflective tiles or shingles. This is known as the albedo effect and many studies have documented significant energy savings from simply lightening the color of a roof.
