When you cover a large commercial building with asphalt roofing tar, you can drive up your cooling costs. The problem is that the black color of a tar roof will absorb a ton of the sun's energy, and then allow that energy to seep into your home in the form of heat. If you want to save money on your cooling costs, you should instead consider installing a white or a green roof. While a green roof will cost you more money to install, it can save you more money in the long run.
The Benefits of a White Roof
You can save a lot of money on your cooling costs simply by changing the color of your roof. A white roof gets its color by reflecting almost all of the sun's energy away. This is good news because the less heat your roof absorbs, the less heat your AC system has to contend with. A black roof can reach up to 180˚ on a hot summer day. White roofs will stay much cooler and, thus, can save you up to 20% on your cooling costs.
The Benefits of a Green Roof
A green roof refers not to the color, but to what your roof is made from. A green roof will start with a waterproof roofing membrane, which is then covered by a potting material and greenery. What type of greenery you use on your roof depends on your taste. If you have a commercial property, you could plant your roof with grass and then use the roof as a display space. For example, if you sell lawn furniture, you could place the furniture on your roof and give your customer an idea of what it would look like in their yard. If you own a restaurant, you could use your roof as a terrace. Either way, it adds more functionality to you building. Even more importantly a green roof can save you up to 75% on your cooling costs and will provide insulation that can help to reduce your heating costs as well.
While you might not think of your roof when you are looking for ways to save money on your operating costs, you can save a lot of money over the long run by upgrading your roofing materials. White roofs are less expensive than green roofs, but in terms of all-around value, you stand to save more money over the long run by using a green roof.
