When it comes to energy efficiency, metal roofs are the clear winner. They are the most energy efficient roof for residential installations, can last more than 50 years and require very little maintenance. Metal roofs are highly reflective, which is why they get so hot to the touch. This makes them a great choice for hot climates, as they can reduce energy use and costs significantly.Tile roofs are another great option for energy-efficient roofing.
Popular energy-efficient roof tile materials include concrete, clay, and slate. One of the main advantages of tile roofs is their ability to allow air to circulate easily between individual overlapping tiles. This airspace acts as a layer of insulation between the shingles and the roof covering, which promotes year-round energy conservation.Investing in a shingle roof can also make you eligible for federal and state tax credits, helping to offset some of the installation costs. Traditional roofing products contribute approximately 20 billion pounds of waste to the U.
S., while metal roofing systems are made of between 30 and 60% recycled material, are 100% recyclable and can be installed on an existing roof.Most metal roofing products use reflective pigment technology, making your home more energy efficient and reducing your monthly utility bills by up to 40%. In addition, these roofs have interlocking panels that provide resistance to outdoor air and to harsh conditions that can affect the use of public services.Solar shingles are a relatively new technology designed to look like asphalt shingles and offer the same level of protection, while taking advantage of solar energy. Solar shingles are about the same size as traditional shingles: about 12 inches wide by 86 inches long, and have a high conversion efficiency rate of 10 to 20%. This energy-efficient roofing material can reduce a home's energy and utility costs by 40 to 70%.
Each solar tile can produce between 13 and 63 watts of energy, depending on the brand.Solar shingles are lightweight and easy to install and, like common shingles, are designed to withstand rain, wind and hail. They can also generate a return on investment of up to 70% or more and increase the resale value of your home.Cedar roofs are also an attractive option for homeowners looking for an energy-efficient roof. Wood shingles are naturally insulating, helping to reduce the use of HVAC in winter and summer. This material is also completely natural, recyclable and biodegradable.Solar panels are more affordable and portable than solar shingles, while solar shingles are more attractive and can have a longer lifespan.
If you live in an area prone to wildfires, you'll want to avoid wooden shingles, which, while energy efficient, are more flammable than other options. Instead, opt for a metal roof, which is naturally flame resistant.Overall, metal roofs offer homeowners the best combination of affordability, durability and energy savings. White metal roofs have the highest solar reflectance but silver metal will also have a positive impact on your energy bills. Asphalt shingles are another affordable and energy efficient roof option - just make sure you choose one with light-coated granules so that the roof reflects more sunlight.Concrete tiles maximize natural energy efficiency while providing a gorgeous rooftop that could be the topic of conversation in the neighborhood.
They can last up to 100 years with proper roof maintenance but come with some drawbacks - they're heavy, susceptible to mold and water damage, and can fade and deteriorate over time.Always check with a local roofing contractor before applying any roofing material to an existing roof as painting the shingles can void the roof warranty or damage the roof. Experts recommend installing a water and ice protector instead of painting.
