Harness The Power Of Roof Reflection To Reduce Your Cooling Bills
You've probably heard the advice to wear light-colored shirts on a hot day because they reflect more sunlight, keeping you cool. If you've followed this advice, you may have realized just how effective this strategy really is! When trying to save money in your cooling bills, you can put the same concept to use -- but with your roof. Here's a closer look.
How can you use reflectivity to keep your home cooler?
Your home's roof absorbs a certain amount of heat from the sun. This heat is transferred into your attic, and then into your home. The more heat is transferred, the harder your AC unit will have to work to keep your home cooler.
A standard black roof, just like a black t-shirt, absorbs a lot of sunlight, resulting in a pretty pronounced warming effects. However, there are a number of more reflective roofing surfaces that reflect more sunlight than they absorb, resulting in lower cooling bills.
What are your options for more reflective roofs?
The easiest option is just to choose lighter-colored shingles. For instance, you could pick light tan or pale green shingles instead of black or light brown ones.
An even more effective option is to look specifically for shingles marketed as "cool shingles" or "reflective shingles." These are typically made with granules that have a slight metallic property to them. As a result, they reflect more sunlight than even lighter-colored standard shingles. From close up, they might have a slightly metallic look, but they look almost exactly like traditional shingles from close-up.
Still another option is to opt for a metal roof instead of one made from shingles. Metal is, by nature, reflective. However, it does have a different look than shingles so you'll have to decide if this is a look you enjoy.
How can you make your reflective roof even more energy-efficient?
Regardless of which reflective option you choose, you should also be sure to insulate the attic well. Even the most reflective shingles do absorb some heat from the sun -- and insulation will minimize the amount that actually warms up your home.
To learn more about your reflective roofing options, talk to a roofing company in your area. They can help you choose between standard light-colored shingles, reflective shingles, and metal roofing. A good place to start is by getting a few estimates so you know what you can afford and what will look best on your home.
