3 Hot Types Of Cool Roofs For Commercial Buildings

So, the time has come to replace the roof on your commercial building. Replacing a roof is never a cheap project, but you can save some money in the long run by choosing to have a cool roof installed. Cool roofs are designed to reflect the sun's rays instead of absorbing them, leading to a lower overall temperature inside and around the building. This is good for you, as it lowers the amount of energy used to cool the building. Your new cool roof will save you money on energy bills for years to come. It's also good for the community surrounding your building, because cool roofs help reduce the overall temperature in the vicinity of your building, which lessens the heat island effect in your area. The only problem is deciding which cool roof is right for you. Check out several types of cool roofs that are commonly used on commercial buildings.

Foam Roofs

In addition to being a cool roofing material, spray foam roofs are beneficial because they cost less to install, and because their life can be extended almost indefinitely with recoating. This roofing material can be installed over many existing roofs, so instead of having to pay for the labor to remove the old roof, you'll only pay for the application of the new roof. Because the foam can be sprayed in any shape, this is a great choice for commercial roofs that have a lot of features, vents, or machines to work around.

To install a foam roof, your commercial roofing contractors will first thoroughly clean your existing roof, and they'll apply a primer on top of the existing material. Some companies use a robot to apply the closed-cell spray insulation and the reflective top coat. The insulation and the reflective coating both contribute to making your roof as energy efficient as possible, conceivably reducing your building's energy bill by as much as 50%.

Coated Metal Roofs

If you'd rather replace your building's entire roof, a coated metal roof is another good choice for a commercial building. Metal is one of the longest-lasting roofing materials on the market, so it's a perfect choice if you're living in an area that's prone to hurricanes or other potentially damaging weather phenomena.

When you choose a coated metal roof, your roofers will apply a spray-on reflective coating that is usually white in color. This is not simply a layer of paint, however. In addition to reflecting the sun's rays, this coating extends the life of your roof by waterproofing it and protecting it from rust and leaks. Not only will your metal roof save money on your energy bills, it will also outlast many other roofing materials, which will save you money on repairs and replacements.

Built-Up Roofing (BUR) Systems

Built-up roofing systems are a popular choice for flat commercial roofs. This method of commercial roofing has been in use for many years, so it has a long track record of success. A BUR system is made up of several layers of different materials. Usually, these layers include a base sheet, several layers of reinforced fabric, and a top layer made of asphalt or coal tar. All of the different layers help to insulate the building and keep out the heat from the sun. The many layers also make this roof difficult to damage.

BUR systems can be made reflective in one of several ways. One technique is to embed reflective materials in the top layer of asphalt or tar. Another option is to apply a reflective coating on the finished roof. And some BUR systems are cool because they add an extra layer sheet of reflective mineral granules. Which method your roofer uses to create a reflective surface is based on your preference and the needs of your building.

If you're ready to get the new roof that your building needs, save money on your energy bills, and help your community by doing your part to reduce the heat island effect, a commercial roofing contractor in your area can inspect your existing roof and help you decide which roof is right for you.
