Does a white roof keep your house cooler?

A white roof can emit up to 90% of absorbed heat, maintaining a stable, cooler temperature inside your house. This increases energy efficiency, reduces utility bills, and extends the life of your roof.

Is it good to have a white roof?

It has long been known that installing white roofs helps reduce heat buildup in cities. But new research indicates that making surfaces more light-reflecting can have a significant impact on lowering extreme temperatures – not just in cities, but in rural areas as well.

How much cooler is a house with a white roof?

Conclusion #2: White Roofs Increase Energy Efficiency

During the maximum internal temperature increase hours of 7:00am – 5:00pm, a white roof is 6.97% cooler (more energy efficient) than a non-white roof.

What color roof is the coolest?

Since dark surfaces are better heat absorbers, traditional cool roofs are white. Berkeley Lab research has demonstrated that raising the solar reflectance of a roof from about 20 percent (dark gray) to about 55 percent (weathered white) can reduce cooling energy use by 20 percent.

What roof is best for hot climate?

Visions: Cool Roofs

What kind of roof is the coolest?

#1 Metal Roofs

Metal roofs are perfect for hot climates because they excel under extreme temperatures. Metal is reflective and considered a “cool roofing” material. Highly reflective paints and coatings can even further improve your roof's energy efficiency.

What color roof is best for hot weather?

Is white a good roof color?

The first cool roof studies concluded that white was objectively the best roof color for cost effectiveness. Later, studies showed that in cooler, northern climates, cool roofs can still result in a higher annual energy costs for homeowners.

Are white shingles cooler?

White shingles result in better energy cooling costs than black shingles. Shingles of all colors are poor reflectors of the sun's rays. Therefore, shingle color affects the curb appeal as well as energy efficiency.

Is a white roof cooler than a black roof?

Black roofs are known for their ability to absorb a great amount of the Sun's heat energy, which causes the roof surface to become extremely hot. They're typically made out of rubber or EPDM roofing. White roofs on the other hand reflect most of the Sun's heat energy, cooling the roof surface.

Why do people not paint their roof white?

atmosphere, a white roof should act like a natural anti-warming device, while also reducing your energy costs by keeping your house cool in the summer. Turns out, painting your roof white would be simply a massive waste of white paint. negative effect in the winter.

Does white roof reduce heat?

White Roofs Can Save You Money

White roofs absorb much less heat, the interior of your house will stay cooler, reducing the need for air conditioning. Another way to keep your house cool if you live in a hot climate is to use UV blocking window inserts. They block solar heat gain through your windows.

Is a white or silver roof better?

When it comes to metal roof coatings, white is your best option. In fact, in 2009, U.S. Secretary of Energy Steven Chu encouraged Americans to paint their roofs white as a means of combating global warming because of the increased energy efficiency.

Do white roofs look dirty?

False, White roofs attract and retain dirt easily which quickly diminishes some of the positive aspects of the membrane. Unless routine maintenance and power washing is completed a white roof will often dull and look dirty. This is especially true when you are removing a black roof and installing a new white roof.

Do white shingles save energy?

Some roof coatings will make the roof a lighter color, such as white, or use special reflective pigments that reflect the sunlight. Others will provide more solar heat reflectivity. This reflectivity can help with energy savings in warm weather and especially during summer months.

Does a white roof reflect the sun?

According to Lawrence Berkeley Laboratories, white-coated roofs can reflect 60 to 85 percent of the solar energy that hits them and stay as little as nine degrees above air temperature. Dark-colored roofs, by contrast, typically reflect 20 percent of sunlight or less, and a black asphalt roof reflects only 5 percent.

Why don't we use white shingles?

The main drawback of white shingles is that they won't be able to absorb heat as well as black shingles would during the colder seasons of the year. As you can imagine, absorbing heat during the winter could help you reduce the amount of heat your heating system needs to crank out to keep your home warm.

Does the color of your roof affect house temperature?

First things first, the color of your roof can majorly impact the temperature of your house. The darker your roof is, the hotter your house will be. Darker roofs absorb more heat, and the wood beneath the surface of the roof will be much hotter.
