Tips: Energy-Efficient Roofs


If you've ever stood on a roof on a hot summer day, you know how hot it can get. The heat from your roof makes your air conditioner work even harder to keep your home cool.

Cool Roofs

If you are building a new home, decide during planning whether you want a cool roof, and if you want to convert an existing roof, you can:
  • Retrofit the roof with specialized heat-reflective material.
  • Re-cover the roof with a new waterproofing surface (such as tile coating).
  • Replace the roof with a cool one.
A cool roof uses material that is designed to reflect more sunlight and absorb less heat than a standard roof. Cool roofs can be made of a highly reflective type of paint, a sheet covering, or highly reflective tiles or shingles.
By installing a cool roof, you can lower the temperature of your roof by up to 50°F and save energy and money by using less air conditioning. Cool roofs make spaces like garages or covered patios more comfortable.
As cool roofs become more popular, communities will benefit from fewer power plant emissions and less demand for new power plants. Cool roofs can lower outside air temperatures, reducing heat islands in urban areas.
Nearly any type of home can benefit from a cool roof, but consider climate and other factors before you decide to install one.

Green Roofs

You may also consider installing a green roof. Green roofs are ideal for urban buildings with flat or shallow-pit roofs, and can include anything from basic plant cover to a garden. The primary reasons for using this type of roof include managing storm water and enjoying a rooftop open space. Green roofs also provide insulation, lower the need for heating and cooling, and can reduce the urban heat island effect. This roof type can be much more expensive to implement than other efficient roof options, so you should carefully assess your property and consult a professional before deciding to install a green roof.

  1. Roof is a part of the house where attention must be place. One must consider the quality of materials used to stand any type of weather conditions.

  4. Metal roofs are one of the common cool roofs or reflective roofs out there in the market. Metal roofs that are painted with special coats greatly decrease the heat transferred from the roof to the attic. It is also a common choice, since metal roofs are known for their durability and low-maintenance requirements.

  5. It is true that metal roofs are known for their durability and low-maintenance requirements, but it does not exempt them from the wear and tear of the passing of time. So, keeping a schedule for maintenance is still important to keep it in good condition. This goes for any type of roof as well, because there isn’t a material yet made to withstand the wear and tear and the oxidation of time.

  6. Many structures today have cool roofs, while green roofs are growing in popularity. Having green roofs is very favorable because you get to mitigate the surrounding heat and commune with nature at the same time. Everyone thought that growing plants in a busy and modern city was not possible a couple of years back. Well it is now, why can we not do our part in conserving nature while doing our job?

  7. I agree with Pleasance, such a nice name by the way, that metal roofs are known for their durability, but they are not exempted from the wear of time. Corrosion is the common enemy of metal roofs, so it will be best to do roof recoating every six months to ensure the roof’s longer life service.

  8. @Willie: The green roofing trend is indeed becoming popular in all over the world. In fact, there are states that promote and implement green roofing system. They took notice of its benefits and so, they started to embrace this brilliant trend. It not just makes an ordinary building turn into a magnificent space, but also helps to save Mother Earth.
