How Can White Metal Roof Save Energy?

Everyone knows as a kid that a white shirt keeps the body cooler than a black shirt. The principle holds not only for shirt and body temperatures but also for roofs and houses, as shown by experiments.

Beyond the basic colour and material, there are a variety of variables that influence how much energy a white metal roof saves, but energy savings start with the colour white.

Solar reflectance and thermal emissivity, as well as other roofing and construction techniques, are used to create cool roofs that save energy.

Solar reflectance (SR) is the power of a surface to reflect solar radiation away from itself, expressed as a ratio. More solar radiation is reflected away from the roof as the reflectance increases. Solar reflectance is higher in white and other light colours than in darker colours.

Thermal Emissivity (TE) is the potential of a surface to re-emit or release absorbed heat expressed as a ratio. The emissivity of pigments and chemicals is more important than the hue. To improve the material’s thermal emissivity, special pigments can be applied to any paint. Up to 90% of absorbed solar radiation may be re-emitted by a highly emissive painted or granular coated metal roof.

If a roof can reflect the majority of solar radiation and rapidly release a large portion of absorbed heat, the structure underneath it can stay cooler for longer while consuming less energy.

Solar reflectance and thermal emissivity, on the other hand, are just one component of a cool roof solution.

Ventilation, which involves creating a dead air gap between the cladding and the deck, allows air to flow freely under the roofing material while still providing some insulation. Warm air may escape as cooler air is drawn in to replace it, creating a convection cycle that protects the structure below from excessive heat.

In contrast to asphalt shingles, which are heavy and thick, metal roofing materials have a lower thermal mass. High thermal mass materials take a long time to heat up, but they also take a long time to cool down. Metal has a low thermal mass, so it heats up slowly while rapidly releasing absorbed heat.

Solar reflectanceIn the cooler months, interior reflectance is advantageous. A heated building with a white roof will reflect heat into the interior rather than only away from the exterior surface, allowing less heat to escape through the roof and saving heating costs and electricity. Insulation and radiant barrier coatings for attics have been developed using the same idea, but a white metal roof has always had these characteristics.

Benefits Of White Metal Roof

Steel is one of the most eco-friendly building materials available. It’s both long-lasting and recyclable. The majority of steel in use today is made up of both recycled and virgin steel. The benefits of a white steel roof are increased by energy efficiency and lower energy prices.

A reflective metal roof will save a home up to 40% in summer cooling energy costs. A highly emissive metal roof can reduce urban air temperatures by up to 12 degrees, offering an environmental advantage that extends beyond the structure.

  • Less energy consumption means lower peak energy usage, which means fewer outages.
  • CO2, sulphur dioxide, nitrous oxides, and mercury emissions from power plants are all reduced.
  • The urban heat island effect is reduced by quickly re-emitted heat, which decreases energy usage within a community.
  • No materials end up in a landfill when a metal roof is replaced; steel is recycled, while asphalt shingles must be stripped from the roof and hauled to a landfill.
  • A white roof has the advantage of making a building appear taller, which a few buildings and homeowners may appreciate.

Photovoltaic panels can be mounted on a standing seam metal roof to collect solar energy. A metal roof can also be mounted directly on top of asphalt shingles, lowering landfill waste and scrap transportation costs even further.

Because of its high solar reflectance, a white metal roof saves energy. Additional coatings and pigments will improve a white roof’s thermal emissivity, resulting in even more energy savings.

A roof with white metal panels and proper ventilation, as well as photovoltaic cells, can not only conserve energy but also generate it. With the same advantages, white metal roofs can be used on both low and steeply sloped roofs.

Metal roof panels are available in a variety of colours, textures, and profiles, allowing you to choose a roof that meets your neighbourhood’s requirements while keeping your energy bills low.
