Energy Star Solutions
ENERGY STAR roof specifications are not restricted to any particular type of roof product and include metal roofing products, roof tiles, asphalt shingles, single-ply membranes, roof coating products, and modified bitumen.
ENERGY STAR Qualified Roof Products
ENERGY STAR qualified roof products reflect more of the sun’s rays. This can lower roof surface temperature decreasing the amount of heat transferred into a building. Energy Star Solutions save your family money. Roof products qualify for the ENERGY STAR label based on their solar reflectance, without compromising product quality and performance.
ENERGY STAR labeled roofs are more common on commercial buildings, but can also be used on residential homes. You’ll get the most benefit if you live in a hot sunny climate where you are using your air conditioning a lot, however, the structures in the southwestern Ohio area can still benefit from these features. If your house is already shaded and the roof is not exposed to much sun, then a reflective roof may not provide a significant benefit. The benefits will also be lessened if the attic space is well insulated.
Van Martin has a genuine concern in helping to maintain and improve the environment for future generations. In this regard, metal roofing meets the criteria of recycled content, recyclability, and energy efficiency. Metal roofing is one of the most energy-efficient roofing systems available and tests have shown that it can save you up to 40% on cooling costs.
In addition, it’s not asphalt-based like shingles, which means its production doesn’t continue to fuel our country’s biggest addiction… oil. Although these are the major drivers, there are many other reasons why metal roofing is gaining in popularity.
It is a reflective roof product that lowers roof surface temperature by up to 100｡F, thereby decreasing the amount of heat transferred into a building’s interior. ENERGY STAR qualified roof products save money and energy by reducing the amount of air conditioning needed to keep a building comfortable.
Products bearing the ENERGY STAR labels are more energy efficient than standard products, thereby saving energy and money. In general, ENERGY STAR qualified products including: appliances, HVAC equipment, office equipment, residential lighting, and even homes, reduce energy costs by at least 30 percent.
Energy star solutions and Roof products that meet or exceed solar reflectance, without compromising product quality and performance, qualify for the ENERGY STAR label. Manufacturers voluntarily sign an agreement with ENERGY STAR called a Partnership Agreement (PA) allowing them to place the ENERGY STAR label on the packaging of qualifying roof products. They can also use the label in product promotions and advertising for qualified products.
ENERGY STAR roof specifications are not restricted to any particular type of roof product. However, ENERGY STAR expects that, at least initially, metal, single-ply membrane, and roof coating products will be most widely represented.
Ninety percent of the energy in the United States is generated by burning fossil fuels, which creates the air pollution associated with smog, acid rain, and global climate change. By reducing the amount of energy needed to cool buildings, ENERGY STAR qualified roof products help to reduce the production of these air pollutants. Additionally, reflective roof products can help reduce the “heat island effect,”a phenomenon in which cities can be 2 to 8｡F warmer than the surrounding countryside. Such heat islands occur, in large part, because many buildings and paved surfaces are designed with dark materials that absorb heat from the sun. This heat is released at night, causing the air temperature to remain high. The resulting elevated temperature leads to an increased demand for air conditioning in buildings, increased fuel use for vehicle air conditioning, increased levels of smog, and associated increased levels of heat-related and smog-related health problems. Installing reflective roofs helps reduce the heat island effect, decreasing the amount of smog in the air and benefiting the entire community.
Benefits of ENERGY STAR qualified roof products include:
- Saves Money and Energy. According to EPA, about $40 billion is spent annually in the US to air condition buildings — one-sixth of all electricity generated in a year! ENERGY STAR qualified roof products reduce the amount of air conditioning needed in buildings, and can reduce energy bills by up to 50 percent.
- Downsizes Cooling Equipment. A reflective roof can reduce peak cooling demand by 10-15%. As a result, the home or building owner may be able to purchase a smaller, more efficient, and less expensive cooling system.
- Decreases Pollution in Urban Areas. Reduced energy demand means less burning of fossil fuels, which results in less pollution from power plants. Also, ENERGY STAR qualified roof products help to reduce the “heat island effect,” in which dark, heat-absorbing buildings and paved areas make the air in urban areas hotter, and more smoggy.
- Increases Roof Product Life. ENERGY STAR qualified roof products maintain a more constant temperature and reduce thermal shock, which occurs when cool rain hits a hot roof, causing a sharp drop in temperature. During temperature changes, a roof expands and contracts, causing stress and degrading the roof.
Energy savings from installing ENERGY STAR qualified roof products will depend on the geographic location and climate where it is installed, existing insulation levels in the building, the type of roof it replaces, the type of roof installed, and how well it is kept clean and maintained. In general, cooling energy savings can be as high as 50 percent. Additionally, a reflective roof can reduce peak cooling demand by 10 to 15 percent. As a result, building owners may be able to purchase smaller, less expensive HVAC systems.
Homes and buildings located in hot and sunny climates will realize the greatest energy and cost savings. So, people living in southern geographic areas that use more air conditioning will see greater reductions in their energy bills than people living elsewhere in the country.
In general, building owners will save the most money on energy bills by installing an ENERGY STAR qualified roof product if their building has the following characteristics: high air-conditioning bills, a large roof surface as compared to the building’s overall size, lower levels of insulation, and/or a location in a hot, sunny climate. The most cost-effective time to install an ENERGY STAR qualified roof product is when re-roofing, constructing new buildings, or maintaining a roof by applying a coating.
Will I save money by using reflective roof products if my home or building already has a high level of insulation?
An energy-efficient home or building has both reflective roof surfaces and adequate insulation. But, you will notice greater savings on your cooling bills if you install ENERGY STAR qualified roof products on a building with a lower level of roof insulation. However, when installing a reflective roof while constructing a new building, doing a major renovation, or replacing your whole roof system, you should consult with your contractor to maximize savings by making sure an optimum level of insulation is installed.
Due to normal wear and tear, some degradation of roof reflectivity can be expected, particularly within the first few years after installation. Flat roofs may accumulate more dirt and debris because their slope is not great enough to allow washing by rain. Following maintenance procedures minimizes degradation and maximizes energy savings. Consult your roofing contractor or product manufacturer to learn more about recommended maintenance procedures and schedules.
How do ENERGY STAR qualified roof products compare with standard roof products in terms of durability?
ENERGY STAR understands that the water tightness, durability, and longevity of a roof are the primary concerns of building and homeowners. These participating manufacturers must back their compliant roof products with warranties that are comparable to their other roof products.
The ENERGY STAR label will appear on roof product packaging and advertisements. If you are installing or replacing a roof on a commercial or residential building, be sure to ask your roofing contractor or manufacturer about ENERGY STAR products.
