Living in Florida, you likely take steps to keep your home energy-efficient to keep your home cooling costs down year round. However, you may not realize that choosing the right roof for your home can help lower your home cooling bills drastically. Some roof materials reflect much more sunlight away from your home while remaining cooler to the touch. When your roof remains cooler, it passes less heat into your home.
Thankfully, energy-efficient roofs come in many materials, colors, and styles, so you don’t have to sacrifice your home’s aesthetic appeal to keep your home cooler and save money on your energy bills. Read on to learn how to choose the most energy efficient roof to keep your Florida home cooler, no matter which roof material you prefer.
Metal roofs are becoming much more popular than ever before. In fact, as of 2016, metal was the second most popular roof type in the United States. While many people like metal roofing because it can be made from recycled materials, others prefer it due to its heat resistance that cannot be matched by any other material.
Not only is metal a naturally reflective material that reflects the sun’s UV rays away from the surface, but when a metal roof is installed, an airspace called a thermal break can be left between the outer metal roof and the support system below it.
This keeps the heat that the metal does absorb from transferring directly onto the roof decking and then into the home. Instead, much of the heat passes into the thermal barrier instead.
For extra thermal resistance, choose a metal roof with a heat-resistant granular coating or a special paint meant to reflect even more of the sun’s harsh rays. Some of these coatings also come with additional waterproof protection to protect your roof from rust and corrosion.
Asphalt Shingle Roofs
If you prefer the appearance of a shingle roof compared to one made of metal, then don’t worry, because some shingles are relatively energy efficient as well.
Asphalt shingles are the most popular roof material due to their durability and low cost. While traditional asphalt shingles are not very energy efficient, cool asphalt shingle can be. Cool asphalt shingles are coated with a special granular substance that reflects the sun’s UV rays more efficiently than asphalt alone.
In addition to opting for cool asphalt shingles, choose light-colored asphalt shingles instead of black ones. In general, the lighter the color of a roof material, the less of the sun’s heat it absorbs and then transmits into the rest of the home.
Many types of tiles can be used to create an energy-efficient tile roof.
Terracotta is a type of fired clay that has a reddish brown color, and terracotta tiles naturally reflect up to 34 percent of the sun’s UV rays. In addition, terracotta tile is heat-resistant due to its hardness and less porous nature after being baked in a hot kiln. Both of these properties lead to terracotta tile absorbing less heat naturally.
For additional roof heat resistance, be sure to choose terracotta tiles that are curved in shape — this curved shape allows air to circulate underneath the tiles to keep the tiles cooler.
Other Clay Tiles
If you find that terracotta tiles are out of your budget, since they are one of the more expensive roofing materials, then other more affordable clay roof tiles can keep your home just as cool as terracotta tiles can. For the best thermal resistance, choose thick clay tiles that are light in color and coated with a reflective coating.
Another very heat-resistant tile roof option that is even more affordable than clay is concrete tile. Concrete tile is made of a combination of sand, water, and cement that is then baked. If you don’t like the traditional grey color of concrete, then you can choose dyed concrete tiles that are available in a variety of colors. However, be sure to choose a light color for maximum heat resistance.
In addition, ask your roofer for concrete tiles that are curved in shape like most terracotta tiles are. This will allow air to circulate under and around the tiles to keep them extra cool. In fact, white concrete S-tiles that have a curved shape reflect almost 75 percent of the sun’s rays, which makes them even more energy-efficient than their clay counterparts.
