Save money with an 'enlightened' roof — and decorate too

All roofs protect us and the interiors of our homes, but they can do so much more. They can be the collection and distribution point for an inexhaustible supply of free natural light and energy.

A roof that uses Energy Star-qualified venting skylights, for instance, admits healthful natural light while providing passive ventilation through the natural “chimney effect” of rising air. This is not an insignificant consideration especially in kitchens and baths that have higher moisture and humidity levels than other areas of the home.

Another kitchen- and bath-specific issue that skylights help address is the need for privacy. Many modern homes are built on small lots, in proximity to neighboring houses. “Light from windows is rarely enough, especially in places where lot sizes are small,” says Jennifer Powers of the design firm Scott-Ulmann.

Areas of the home where traditional skylights with blinds might not work — such as hallways, closets and small, interior baths — can still admit natural light through less expensive Sun Tunnel tubular skylights. And optional light kits turn these units into 24-hour sources of light. Low-profile flat glass models that blend unobtrusively with the roof, and domed models, all offer a fast, easy, less expensive way to transform a home with natural light.

In addition to light and ventilation from above, if you add an Energy Star-qualified solar water heating system, your roof will work even harder for you. And, in addition to monthly power bill savings, these solar thermal systems qualify for tax credits and other savings that significantly reduce the payback time it takes to recover the initial cost.
