If you remember from two of our previous articles relating, the bp oil spill (part 1 and part 2) to the use of shingle roofing than this article will make perfect sense. Every year over 13 billion pound of asphalt shingles go into land fills, which could all be prevented because metal roofing is:
- 100% Recyclable at the end of it’s lifespan
- Metal roofing has a lifespan 2-3 times as long as shingles
- Metal roofs already have recycled content of 20-30%
- Steel is the most recycled material in North America
- Shingle Roofs are made up of more oil and raw materials (see chart)
But what about rainwater? Is there more poluttion from a metal roof or a shingle roof? The answer is shingle roofing is more toxic because:
- Shingle roofs have a permeable surface and rain water washes away the oils and particles that rise to the top of the shingle as the shingle drys out
But what about solar reflectance and insualtion? Which roof is more energy efficient? Metal roofing is more energy efficient because:
- Metal roofs are coated to reflect sunlight and have infared pigments to keeo the roof cool in the summer
- Metal roofs are also much thinner and have less mass which means they hold less heat given them a higher emissivity
- Metal roofs are tax credit eligible for the $1500 rebate!
And finally, what about integrating solar? Metal roofs are the best option for solar because:
- You can go with traditional solar panels using an s-5 bracket which requires no roof penetrations or
- You can go with solar thin film, an aesthetically pleasing and extremely durable option

Going “Green” is a global concept that needs to be executed locally. We have found that the growing trend of metal roofing directly relates to the ecological awareness of homeowners! Metal Roofing is 100% recyclable whereas traditional roofing products, such as asphalt, contribute 13 billion pounds of waste to U.S. landfills annually!!
