Green Pointers

Whether you're tackling a reroofing project yourself or hiring a roofing professional, it's worth your while to get familiar with today's environmentally friendly roofing options. A good roof will hold up for decades, protect your home from water damage, keep your repair and replacement costs in check, and reduce your heating and cooling bills. They can also provide valuable real estate for locating solar panels or a beautiful roof garden.

Here are some great tips and information for reroofing.

Step 1


  When it comes time to reroof your home, choose a durable material. Durable roofing materials are better able to withstand the elements, including the sun's heat and ultraviolet light. Short-lived roofing materials result in more waste going to landfills and more money spent on roof replacement. In extreme cases, early failure of a roofing material can result in water damage to the home.

It's important to check the fire rating and warranty period of any roofing product. Avoid shakes and shingles made from cedar and other woods. These can be a fire hazard. They also tend to have a shorter life span than other roofing materials and they are high maintenance. If you must have wood shakes or shingles, choose a product that has been certified as sustainably harvested by the Forest Stewardship Council (FSC).

Step 2


  Overhangs and gutters reduce maintenance and repair costs by helping keep water off of the siding, windows and doors, thereby reducing the likelihood that rot and mold will develop. Gutters provide a pathway for water to flow off of the roof without hitting the walls, splashing back onto the foundation and siding, dripping onto people and eroding the landscape.

Overhangs can also shade windows, helping keep the home comfortable and reducing air conditioning costs. And overhangs can provide protection from the sun's harsh UV rays, which can degrade building materials and furnishings.

Ideally, a home's entire roof should be built with at least a 16-inch overhang with gutters. When building an addition or substantially remodeling areas of the house, be sure to include adequate overhangs with gutters on the new sections of the roof. Consider adding deeper overhangs where needed to shade walls and windows to provide cooling during summer.

Instead of draining gutters into the sewer system, drain them at least 24 inches from the building and into a rainwater cistern. You can use the stored water to irrigate your landscaping. Or drain the gutters toward adjacent landscaped areas that are graded to receive the excess water; this will allow the rainwater to water vegetation and recharge groundwater. Check with the local building department for applicable codes.

Step 3


  If you are reroofing, building an addition or doing a major remodeling project, look for opportunities to add solar electric or solar hot water panels to the roof. Even if you don't plan to add solar right away, reserving roof space for future panels can be a smart move. Read more in our know-how feature on Renewable Energy.

Step 3


  The sun's rays beating on the roof can really heat up a house and drive up cooling costs. Good insulation, a radiant barrier in the attic, and reflective roofing materials are all excellent strategies for blocking heat. Another great option is utilizing shade trees. Plant them where they will cast summertime shade on the roof when they reach maturity. Keep shade off of roof areas where solar panels may be located now or in the future.

Step 3


  Proper flashing details help increase the roof and building life. Read our know-how feature on Moisture and Pest Control for information about flashing.
