The Cool Roofing Facts: Energy Star estimates that the average Heating & Air Conditioning Costs for Homeowners in the U.S. is $1,000 per year. The Cool Roof Rating Council (CRRC) estimates that the average energy savings for reflective shingles to be between 7% and 15% of cooling costs.
What color shingles are most energy efficient?
“Cool” roofs are lighter in color than traditional black asphalt or dark wood shingles and save energy by reflecting light and heat away rather than absorbing them. This is known as “the albedo effect,” and many studies have documented significant energy savings from simply lightening the color of a roof.
Does shingle color affect energy efficiency?
Roof color alone doesn’t affect home temperature and energy efficiency. The roofing material also determines how reflective your roof is. … Therefore, light-colored asphalt shingles may absorb more heat than a dark-colored metal roof. Roofing is a long-term balance between aesthetic appeal and energy efficiency.
Do asphalt shingles provide insulation?
Old roof shingles offer absolutely no insulating value. To insulate, a material must trap air, and roof shingles won’t do this. In fact, they can actually have the reverse effect since old layers of shingles can act as “heat sinks,” trapping and storing the sun’s heat. … Heat buildup is greater on a two-layer roof.Will black shingles make house hotter?
How can roof color affect the heat of your home? Generally, lighter colored roofers will reflect heat away from your roof and darker roofs will absorb the heat and transfer it into the house below. As black is obviously the darkest roof you can get, this color will absorb the most heat and warm your home the most.
What are cool shingles?
COOL roofing shingles are specially designed with solar-reflecting granules (granules that reflect the sun’s rays) to help decrease the amount of heat transferred into a home. These shingles can help make your home more comfortable and may even be required if you live in certain geographical areas.
What roof is best for hot climate?

What color roof is best for resale?
Roofs with good resale value tend to be neutral colored, such as tan, cream, brown, black or gray. These colors are classic and tend to stay in style over time. Trendier roofs include shingles that are mixed, with various color combinations of browns or blacks and grays.Do cool roof shingles work?
Installing a cool roof is most beneficial in a warm climate, where the winters are not cold enough to require the inherent heat gain of a traditional roof. Southern climates, including California and Florida, are prime candidates for cool roof installation.
What color roof lasts the longest?Both light-colored and dark-colored shingles can last longer if given the necessary maintenance. The only thing tested and proven about light-colored shingles is that they help us keep the indoor temperature cooler in the hot summer season.

Can you coat a shingle roof?
Two coats are recommended since most asphalt shingled roofs that need to be coated are porous and worn out and will tend to absorb the first coat, while the second coat leaves a protective surface film that stops shingle granule loss, cracking, curling and leaking.
Are architectural shingles durable?
They last longer than standard shingles, often coming with a 30–50 year warranty rather than the traditional shingles’ 20–30 year warranties. The highest quality architectural shingles can have warranties of up to 75 years!
What kind of roof is best for saving energy shingle or metal?
While both asphalt and metal roofing do an excellent job when it comes to keeping your home protected from the elements, metal roofing outshines asphalt shingles in areas of energy efficiency and material durability.
Are black shingles less efficient?
Black and white roofing materials also have different levels of heat retention. While both have nearly identical overnight temperature profiles, black shingles lose heat more rapidly than their white counterparts. Note that black and white are the two extremes on the color spectrum.
How can I make my roof more energy efficient?

What is better fiberglass or asphalt shingles?
Better Durability: Because organic asphalt shingles contain more asphalt than fiberglass shingles, they are more durable, and as a result, they last longer than fiberglass. Their added durability also means that they are more likely to last through severe storms without getting blown away or damaged.
What is the most popular roof shingle?
Asphalt shingles remain far and away the most popular choice because they’re relatively inexpensive and easy to install. In CR’s roofing tests, we found that some shingles performed better overall than others that cost more. And some provide a beautifully layered look or come in huge arrays of colors.
Should I put a second layer of shingles on my roof?
A second layer of shingles will decrease the integrity of your new roof and lower its lifespan. That’s because shingles aren’t designed to have a second layer of shingles on top of them! Plus, all that extra moisture and heat being applied to the first layer of shingles will make that first layer age faster.

What does Sri mean in roofing?
SOLAR REFLECTANCE INDEX (SRI): Incorporates both solar reflectance and thermal emissivity in a single value. SRI measures the roof’s ability to reject solar heat, defined such that a standard black (reflectance 0.05, emittance 0.90) is 0 and a standard white (reflectance 0.80, emittance 0.90) is 100.
Do cool roof shingles cost more?
How much does cool roofing cost? According to the EPA, reflective shingles may be the same price as premium standard shingles and between $0.10 and $0.20 more per square foot than regular mid-priced shingles.

Do asphalt shingles reflect heat?
The material of your roof can also have a big impact on how much heat is absorbed into your home. For example, an asphalt roof only reflects an estimated 30% of light that hits your home, regardless of if you have dark or light shingles.
Are there energy efficient roofs?
A cool roof is designed to reflect more sunlight than a conventional roof, absorbing less solar energy. This can save energy and money in buildings with air conditioning, or improve comfort and safety in buildings without air conditioning, by reducing heat flow from the roof into the occupied space. …
