Energy Savings also contribute to help make up the initial cost

Did you know that a metal roof can greatly decrease your air conditioning bill during the hot months of summer? One of the two significant energy-saving features of metal roofing is that metal has higher reflectivity (albedo) properties, which allow it to reflect the heat radiation away from your roof, keeping your house cool and your energy bill low.

The other energy-saving advantage is by helping to reduce the heat soak of an attic through emissivity, especially in the evening. Since metal has a high thermal conductive potential, your roofing will help transfer the pent-up heat from your attic at night. After all, our monthly air conditioning costs can add up to a big chunk of money during the summertime.

“Emissivity can also contribute to a cool roof. In warm and sunny climates highly emissive roof products can help reduce the cooling load on the building by releasing the remaining heat absorbed from the sun. However, there is also evidence that low emissivity may benefit those buildings located in colder climates by retaining heat and reducing the heating load. Research on the benefits of emissivity is ongoing. Discuss reflectance and emissivity with your roofing contractor to determine what characteristics matter most given your unique climate. ” Source: energystar.gov/products/building_products/roof_products/cool_roofs_emissivity

We’ve given you the basics, so now let’s discuss.

While using the newest techniques and panels, we also source many of our products from local businesses and press many of our own panels with our modern machinery and manufacturing techniques. Our service area extends west, north, south and east of Loomis in varying distances. Our general areas cover the greater Sacramento area, the northern foothills including Placer, El Dorado, Sutter, Yuba and Nevada county as well as the Northern/Central Valley area, extending down south to Stanislau and north to Butte. Even if your project falls outside these counties, we may still be able to help, so feel free to reach out to us today

Having high thermal emittance (to cool down rapidly at night), and higher reflectivity; modern pigments in metals can be both dark and highly reflective of thermal radiation (sunlight). This means your attic will both be slower to heat up in the summer days and quicker to cool down in the summer evenings.

Wikipedia agrees: “For building products, thermal emittance measurements are taken for wavelengths in the infrared. Determining the thermal emittance and solar reflectance of building materials, especially roofing materials, can be very useful for reducing heating and cooling energy costs in buildings. Combined index Solar Reflectance Index (SRI) is often used to determine the overall ability to reflect solar heat and release thermal heat. A roofing surface with high solar reflectance and high thermal emittance will reflect solar heat and release absorbed heat readily. High thermal emittance material radiates thermal heat back into the atmosphere more readily than one with low thermal emittance.”

To save the very most on cooling, you may even consider creating an air gap over your existing roof that shields your attic from the extreme heat daily. With a new metal roof and air gap you can further those cooling savings to their logical maximum!

Metal roofing can be the more sustainable option for a home. Because shingle roofs last roughly 15 years before major maintenance, an estimated 20 billion pounds of asphalt shingles are sent to landfills in the U.S. alone every year, an almost unfathomable number and amount of waste. That number is not surprising seeing as how the NAHB found the average asphalt shingle roof lasts just twenty years. Waste could be saved every year makes stainless metal that much more reasonable! Metal roofing, at the same time, can be both recycled and use recycled mateial. Many aluminum metal roofs are manufactured with up to 95% recycled post-consumer metals!
