EuroSlate and EuroShake rubber roofing products contain 95% recycled content (mostly old tires), says the maker. They mimic slate tile and sawn cedar shakes, come in 36-inch and 40-inch-wide panels, and are held in place with standard roofing nails. An adhesive strip bonds successive courses to one another, and built-in tabs ensure correct exposure. The reported cost to the contractor is just under $300 per square.
