COOL roofing shingles are made mostly of solar-reflecting grains that reflect sunlight. This reduces heat transfer to the home.
Cool roof shingles are a great choice, especially if your home is in a hotter area like Florida. Cool roof shingles reflect light instead of absorbing it. This makes your home cooler and more efficient than other roofing materials which absorb heat and heat.
Did you know that heat from the roof can adversely impact cooling costs and comfort in hotter areas? Cool roof shingles are a great option to increase energy efficiency and comfort.
What should you look for in cool Shingles?
An ENERGY STAR label is available on many lighter-toned products in the United States when searching for Cool Shingles. Before you choose a cool roofing shingle, make sure it meets your state’s cool roofing energy regulations. The following are some of the aspects that influence the Quality of cool roof shingles
Absorbing Heat
Sometimes, a poorly ventilated attic can cause your home’s temperature to rise. High temperatures can increase your energy bills as you will need to cool your home more often or at a lower temperature. If you notice an increase in energy costs, it is worth having your roof and attic inspected by a roofing professional.
Solar Reflectance
A good cool roof shingle should have a solar reflectance of at least 0.25 at its initial measurement. The three-year solar reflection measurement should be below 0.15. The sun’s rays produce visible and invisible light from your roof when it shines down upon it. Your roof’s solar reflectance is determined by the way it reflects these waves. It is worth noting, however, that the greater the solar reflectance of an asphalt roofing shingle the more waves are bounced back into space.
Thermal Emittance
There is a range of thermal emission values from 0.0 to 1. The higher the value, the more heat is transmitted to the home. Although the ENERGY STAR standard doesn’t include a thermal emission value for cool roof shingles (the value can be found in specification sheets).
When choosing items with high or very low thermal emission, it is important to take into account your local climate. Material with high thermal emission may be more suitable for hot and sunny climates such as Florida. Materials with low thermal emittance, on the other hand, may help houses reduce their heating loads in very cold environments.
