Cool roof coatings are thin films that can be applied on top of your roof. They are made from a material that naturally reflects the sun's rays, so your building does not become as warm and your cooling costs decrease. While cool roof coatings are an energy-efficient choice for many homeowners, they are not right for every situation. Weigh these pros and cons to decide if a cool roof coating is right for you.
A cool roof coating will extend the life of your roof.
High temperatures cause roofing materials to break down. A cool roof will stay about 80 to 90 degrees F cooler than a non-coated roof, so it will experience less wear and tear and likely have a longer lifespan. Also, a cool roof maintains a more even temperature, rather than going through rapid temperature fluctuations like a standard roof. This means there will be fewer contractions and expansions in a cool roof, which will also increase its lifespan.
Your home will be more comfortable with a cool roof.
Does the upstairs of your home tend to get hot and muggy in the summer? A cool roof is likely to fix this problem. Less heat will be transferred through the roof after the cool coating is applied, so your home will maintain a more even temperature. Not only will you be more comfortable, but you'll spend less on air conditioning.
It's difficult to apply a cool coating on top of an existing shingle roof.
There are contractors who offer this service, but it does present some risks. If the shingles are not completely dry when the coating is applied, some moisture will get trapped in the roofing materials. This can lead to molding and premature breakdown of the roof. These risks can be minimized by a knowledgeable contractor, but it is always riskier to apply a cool coating to an existing roof than to a new one.
Some coatings are not as good as others.
You have to be very vigilant when it comes to finding a reliable cool coating. There are some brands that are more hype than quality and will lose their ability to reflect heat and energy after a few years. To ensure you don't waste your money on a less-than-optimal roof coating, work with a roofing company with a long track record of excellence, and do your own research on any roof coating they recommend.
If you are getting a new roof and have the time to do your research, a cool roof coating can be a great choice for your home. However, if you're considering coating an existing roof, it's worth your while to consider whether having a more comfortable home and lower cooling bills is worth the risk.
