Reduce Greenhouse Effect – Use Cool Roof Technology

The idea has existed for years but recent studies have proven that cool roofs can indeed offset carbon dioxide emissions and reduce the greenhouse effect. Recently the US Energy Secretary Steven Chu announced a series of initiatives at the Department of Energy which will help implement cool roof technologies on various DOE facilities and other buildings across the federal government. The move hopes to set an example for the citizens to use sustainable building practices and reduce their carbon footprint.

What are Cool Roofs?

This technology helps build roofs which can reflect solar energy and radiate the absorbed and non-reflected solar energy better when compared to dark-colored roofs. They help reduce energy use and cut energy costs, cur air pollution and bring down the costs associated with roof maintenance also. In fact the Environmental Protection Agency has stated that these roofs will reduce your cooling energy use by 20-70%.

Your roof and its insulation are guaranteed a longer life because they are not subject to extreme temperatures or expansion / contracting cycles. Lower rooftop temperatures also imploding cooler air in the surroundings and reduce the heat island effect which brings down smog levels.

Almost 90% of the homes in the US have asphalt shingle, which are the hottest roofing materials. There are many types of energy efficient roofs which you can use after evaluating the cost, durability and overall environmental impact. If you are considering cool roof technology you will need to evaluate the products before you choose one. As costs vary by material, you will need to get in touch with a certified roofing contractor to discuss your options. Note that there are a number of incentives for cool roofs which include rebates to tax deductions and loans.
