Beautifully Healthier for Homes and the Environment
The growth of metal roofing in the U.S. is directly attributable to the rise of the sustainable design movement. Architects and homeowners have discovered the many environmentally beneficial advantages that metal roofing has over other roofing materials – especially asphalt shingles. Environmental efficiency often goes hand-in-hand with financial efficiency.
Here’s why metal roofing is sustainable:

Long Life Cycle
A metal roof lasts up to and beyond 50 years, or two to three times longer than the average asphalt roof.
Metal Sales metal roofing systems enjoy very long life cycles compared to alternative products - often 50 years or longer. Products that don’t require replacement (or more infrequent replacement) during the lifespan of a structure are more sustainable than those that need to be replaced.
According to the Metal Roofing Alliance, "You can expect a metal roof to last at least 2 to 3 times longer than a regular roof. In general terms, count on a metal roof lasting 40 to 60 years and beyond.
To put it in context, the average life span of an asphalt roof is 12 to 20 years. That lifespan can be shorter depending on the pitch of your roof and the climate in your area. Made of oil impregnated paper or fiberglass, asphalt begins to deteriorate as soon as you expose it to normal weather. A metal roof, however, will never decompose.
Other roofing materials like wood shingle, shake and tile have varying degrees of weather-related problems that lead to breakdown. Wood shingle and shake roofs often need replacement before twenty years. Concrete tile roofs can crack and warp in the freeze/thaw cycle of more northern climates.
All of the above roofing materials are well-outlasted by metal roofing, which retains its good looks and durability decade after decade after decade."
Metal Sales steel contains a minimum of 30% recycled material and is 100% recyclable at the end of its service life.
The vast majority of Metal Sales metal roofing systems are made from steel, the world’s #1 most recycled material. The steel we use can contain up to 30% recycled content.
Metal Sales products last a very long time, but when their useful service life finally comes to an end, the products in their entirety are recycled rather than landfilled. This is due to scrap metal’s significant market value. Because of the ease with which metal is recycled, its ability to be recycled infinitely without degradation, and its wide ranging applications, metal will continue to command top dollar in scrap markets. This market force ensures that the material is almost always re-used and rarely, if ever, landfilled. This is not the case with other building materials.
Conversely, a very small percentage of asphalt shingles are ever recycled.
In fact, they account for the highest percentage of building materials landfilled today.
Plus, asphalt shingles are a petroleum-based product that further taxes our world’s reliance on fossil fuels.
Metal Sales products reduce solar heat gain, lowering energy costs. Our systems enable energy conservation and on-site energy production in alignment with Net-Zero practices. They can contribute credits toward LEED® building certification.
All standard Metal Sales color coating systems are ENERGY STAR® listed and many are certified by the Cool Roof Rating Council. In both cases, Metal Sales products help to reduce the solar heat load on homes and thereby reduce energy expenditures for cooling.
Metal Sales roof and wall panels can contribute to LEED credits
All standard Metal Sales color coating systems are ENERGY STAR listed.
Metal Sales roof and wall systems contribute as the outermost component to a tight building envelope for less air loss and better thermal performance. Additionally, they have material attributes which contribute to a healthful environment and foster energy efficiency.
Declare Red List Free
The Declare label addresses human health and toxicity impacts of building materials. Metal Sales has fully disclosed all of the ingredients its Acrylic-coated Galvalume roof and wall panels through Declare, and they are designated as being Red List Free.
Roofing is a critical element to the overall sustainability of the building envelope.
Metal Sales Standing Seam roofs can accommodate up to 6” of blanket insulation for maximum thermal efficiency.
Additionally, the low thermal mass of metal roofing means that it dissipates heat very quickly once the sun goes behind a cloud or sets for the day. Other roofing materials have greater thermal mass and will continue to radiate captured heat into the structures beneath them even when the sun is not shining.
The installation of a high-performance Metal Sales roof can contribute to lower energy expenditures related to heating and cooling your home.
Integration with Renewable Energy
Metal roofing panels easily integrate with new technologies, such as photovoltaic, micro wind turbines and solar hot water heating.
Roof systems from Metal Sales provide the durability, exceptionally long lifespans and limited maintenance that make them the ideal platform for renewable energy technology.
Metal Sales continues to develop methods that enable renewable energy technology to be more easily integrated into our products and systems. Examples include the integration of polycrystalline and thin-film laminate photovoltaics, micro wind turbines, solar heating and potable rainwater harvesting systems into our metal roofing systems.
Micro Wind Turbines – These smaller, lightweight but powerful devices are easily attached to the standing seams of Metal Sales roof systems. Specially engineered clips, which do not compromise the roof’s weathertight integrity by penetrating the metal roofing panel, are used.
Solar Heating Integration – The sun beating down on a roof is obviously the primary source of unwanted solar heat gain in a building. Cool coating technology helps to significantly reflect the sun’s energy away from a building.
Additionally, the thermal energy that remains can be used to help heat air and water for building operations. Today, standing seam metal roof systems are successfully being employed to accomplish this.
Potable Rainwater Harvesting
Metal (specifically Galvalume) is a preferred roof material to produce the highest harvested rainwater quality for indoor domestic use.
Only a small minority of homeowners live in areas subject to water shortages. Still, the fact that metal roof systems are the preferred roof material from which to harvest potable rainwater speaks volumes about the health and safety of metal, compared to wood or asphalt shingles.
Potable rainwater harvesting engineers prefer metal over wood or asphalt shingles because the latter hold and harbor many pathogens and leach toxins into water. Metal roofs do not contain these toxins. Plus, metal’s slick surface that makes it easier to keep clean of dust, debris, bird droppings, etc. Finally, while clay and concrete tile roofs can be used for potable rainwater harvesting, their porous natures create a danger for bacterial growth, and can cause the loss of as much as a 10 percent of water from inefficient flow and evaporation.1
*Note: Please check with your local jurisdiction about the laws in your area governing rainwater collection/harvesting. See www.ncsl.org for a list of states that allow for rainwater harvesting and how the collected water can be used.
