Average summer temperatures in Atlanta are around 90 degrees Fahrenheit, and the majority of that heat hits your roof. The immediate effects of heat on your roof are seen in higher cooling costs and lower comfort levels indoors, but the heat can also shorten the life of your roof. By taking steps to cool off your home's roof, you can save 10-15 percent on air-conditioning costs and make your roof last longer. Here are the options as you prepare for the extreme summer heat.
Reflective materials that lower the temperature
The sun's ultraviolet rays pound Forsyth roofs all summer long. Over time, the intense heat can cause asphalt roofing to crack and fall apart. Metal roofs also deteriorate from prolonged direct contact with the sun. An easy solution is having a contractor apply a reflective coating to your home's roof.
You may reduce the temperature on your roof by 50 degrees or more when you apply an effective roof coating. Qualified roofing contractors can advise you on the best choice for your home.
Why the effects of heat on your roof are so costly
Air-conditioning costs are one of the biggest energy drains for Americans, but in hot climates, it can be difficult to go without cooling. Taking steps to turn down the roof's temperature can bring your energy costs down as much as 15 percent, according to the EPA's ENERGY STAR website.
Saving money on cooling costs is not the only benefit of reflective roof coatings. Over the long run, roofs that are not overwhelmed by the Georgia sun require fewer repairs and last longer. Simple steps such as applying roof coatings and guaranteeing you have sufficient insulation can help prolong your roof's life.
Considering options for your roof
The decision you make with respect to roof coatings depends largely on the material of your roof. ENERGY STAR-rated aluminum coatings may be a solution along with elastomeric coatings, both of which serve as reflective barriers. When a roof is older, you may need to apply a primer before roofers can apply the reflective coating.
If your roof has already run its course, you will need to replace it. You may consider a cool roof with solar reflective shingles, tiles or paint. These roofs have the potential to lower surface temperature by as much as 100 degrees. Whenever you lower the impact of the sun and need to cool your home less, carbon emissions and energy use drops significantly. Cooler roofs mean greener communities.
Extreme heat can bake your roof and cause you pay more in cooling and long-term roofing costs. Explore your options in reflective coatings to combat the effects of heat on your roof.
