Three Ways To Increase The Energy Efficiency Of Your Existing Roof

Gregory Walker

The type and color of roof you have on your home could be impacting your energy bill, but there are steps you can take to make it more energy efficient. Whether your existing roof is in bad shape and in need of repair or replacement, or whether you're just looking for tweaks to help make it more environmentally friendly, these tips will help you choose the roof that's just right for your lifestyle:

Consider Cool Roofing Materials

Cool roofing materials are those that reflect heat and light back into the atmosphere instead of transferring it to the interior of your home. Metal is a cool roofing material -- so is foam. Shingles, tiles, and slate can qualify as cool, depending upon their color and thermal mass. A cool roof is measured using two factors:

  • Solar Reflectance: The ability of the roof to reflect light.
  • Thermal Emittance: The ability to reflect heat.

On a scale of zero to one, materials that score higher, perform better. 

Apply a Cool Coating

If your existing roof is in good shape, but scores low on the scales of solar reflectance and thermal emittance, you can apply a simple coating that will help improve both numbers. When applied to roofs that are already in existence, these are called field coatings. They go on just like paint to improve your roof's energy performance. Roof coatings can be applied to nearly any type of existing roof.

Install a Green Roof

A green roof is a living roof made of grasses and plants, and even trees if the structure is sturdy enough. Many cool roofs are created atop apartment buildings or large structures within populated cities. The oxygen produced by the plants help to reduce something called the heat-island effect that happens in densely populated areas during the hot season. The heat-island effect accounts for higher temperatures in certain areas of a city due to many buildings placed closely together. This can cause higher energy bills in these areas and increased air pollution. Green roofs made of plant life helps to combat this. The combination of soil and greenery insulates a roof and keeps it cool during even the hottest of summers. 

You can take advantage of the benefits of any of these types of roofing by contacting a roofing company such as Durable Roofing Company to discuss the possibilities. Some options, such as coatings, are easily applied by the homeowner. But the intricacies of something like a green roof needs professional input.

Hi, I'm Caroline. Welding has always been really fascinating to me. One day, when I was at work in my office, we had a leaky pipe in the ceiling. After calling a plumber, he called a welder who came to repair the large, open pipe. As we were all sitting there trying to work, the welder just came in and started repairing the pipe! I had never worked on a construction site before, and I probably never will. But I started thinking about what it would actually be like to work on a construction site, which led to me exploring construction themes and writing this blog!
