HOW ENERGY EFFICIENT ARE METAL ROOFS?
2

• Did you know that metal is one of the most energy
  efficient materials that a roof can be
  constructed from? With a professionally fitted
  metal roof, you could save up to as much as 40
  on your energy bills and still have an
  effectively insulated home during the cold,
  winter months.
• How do metal roofs help save so much energy?
• There are many finishes that can be applied to a
  metal roof, and its these that are the key to
  saving energy. A standard metal roof that hasnt
  been painted, will reflect more solar radiation
  than a roof made of asphalt, which is the type of
  material that absorbs and retains heat.

• If you live in an area of the country with a
  warmer average climate, then a metal roof that
  has been pre-painted or granular coated, will
  reflect more solar energy and help to keep your
  home lovely and cool as it re-emits most of the
  solar radiation thats been absorbed.
• For maximum energy saving results, a reflective
  and highly emissive painted or granular-coated
  metal roof is the best option, as it has the
  capacity to re-emit up to a whopping 90 of
  absorbed solar radiation.

• What is cool-metal roofing?
• Cool-metal roofing is often referred to as the
  most effective of the energy-saving finishes, and
  with its highly reflective coating, it uses cool
  pigments in the paint to increase solar
  reflectance and bring down the temperature on the
  surface of the roof. Properties without
  air-conditioning are helped to feel much cooler
  with this type of roofing, and in those buildings
  that have A/C, the energy needs are reduced.
  Coming with an ENERGY STAR certification and
  often qualifying for tax incentives, cool-metal
  roofing could be an option for you and your
  property.

• Getting your Passive House Institutes
  certification
• Passive House is a construction concept that can
  be applied to any building, and which basically
  means that its a low-energy one, with
  certification involving meeting certain standards
  of efficiency, comfort and affordability.
• Metal roofing is often used on buildings that
  have been Passive House certified, due to its
  high levels of solar reflectance and thermal
  emittance. Here are a couple of other ways in
  which metal roofs can help achieve a passive
  house
• Insulation backup
• Most metal roofs protect their insulation backup
  more effectively, and this goes on to help ensure
  long-term thermal resistance

• Airtight construction
• Metal panels are great for providing an air
  barrier and airtight building, one thing that is
  essential for certification
• High efficiency
• High efficiency windows and skylights can be used
  in conjunction with metal roofing

• Are metal roofs solar friendly?
• Oftentimes, solar energy panels can be installed
  on metal roofs without having to penetrate the
  roof system, and with the longevity of a metal
  roof, solar panels can even be added to an
  existing roof.
• So, with the addition of a metal roof and solar
  panels, your property can easily be upgraded to
  become energy efficient, and you could end up
  saving hundreds of dollars on your utility bills
  each year.
