2022年6月2日 · Cool metal roofing is defined as painted or coated metal products that reflect the sun’s energy to dissipate heat. Cool roofs help to reduce the heat that is transferred into the building, which can result in total cooling cost energy savings ranging from 7% to 15%, according to the Green Building Alliance .

2024年4月16日 · Cool roofs reflect more sunlight and absorb less heat than standard roofs, making them over 50 degrees F cooler, contributing to energy savings and comfort in hot weather. Options for creating a cool roof include materials like modified bitumen, single-ply membranes, cool roof coatings and even green (vegetated) roofs.

Naturally reflective and highly emissive, metal is ideally suited to homes in hot climates. Cool-metal roofing, which is commonly made from steel and aluminum, is available in a dizzying range of styles and colors. Standing-seam roofing can last indefinitely.

2023年8月15日 · Keeping a metal roof cool on your building involves a combination of strategies to reduce heat absorption and improve heat dissipation. Here are some effective ways to achieve a cooler metal roof: Cool Roof Coatings: Apply reflective cool roof coatings to the metal surface.

For homes in warmer climates, pre-painted or granular coated metal roofing systems reflect solar energy and cool your home by re-emitting most of what solar radiation is absorbed. A highly reflective and highly emissive painted or granular-coated metal roof is optimal for reducing energy consumption and can actually re-emit up to 90% of ...

Cool metal roofing stays significantly cooler than traditional roofing materials. In fact, studies show that a cool metal roof can reduce cooling costs by up to 20%. Cool roofing is defined differently by various performance criteria in codes, standards, and incentive programs.

Some common cool roof materials include membranes, shingles, coatings, stone/rock, metal, and tile with high solar reflectance. Other cool roof strategies include ballasted roofing and green roofs.

2012年5月21日 · Metal roofs are probably the most expensive (first cost) cool roof solution, but they also have a favorable life-cycle cost which shouldn't be ignored. From a long term sustainability point of view metal is a good deal, but cool roof shingles shouldn't be dismissed- they run cooler (increasing shingle life) and come in many colors other than ...

Metal Cool Roofs: Metal roofs that are coated with reflective coatings or naturally high reflective materials. Single Ply Membranes : Reflective TPO, PVC, and EPDM membranes for flat roofs. Cool Tile or Slate Roofs: Roofing tiles that reflect solar light or have coatings on them.

2024年9月9日 · Cool metal roofing is a roofing system that has greater solar reflectance. These reflective roofs ensure lower heat even on hot days than conventional roofs. Their coating helps them reflect sunlight and dissipate heat. Cool metal roofs can save total cooling costs and energy savings about 7 to 15%.
