Cut Cooling Costs With the Right Roof Color -- Savings Experiment

The wrong color on your home's exterior can cost you, so if it's time for a new coat of paint or a new roof, keep these tips in mind.

A dark colored roof absorbs quite a bit of solar energy, and shortens life of shingles. It also significantly increases the cost of keeping your home cool. On the other hand, white roofs reflect solar energy, and the heat reduction can lower cooling costs by as much as 20 percent.

If a new roof is not in your budget, consider investing in white titanium dioxide paint and aluminum sheets, which are relatively inexpensive and easy to apply and install. However, dust and dirt can cause the aluminum and paint to lose their reflective properties over time, so reapplication and regular cleanings are a must.

So, if you're in the market for some home improvements, think twice about the colors you choose. The decision could save you a bundle in the long run.
