Concrete Roof Tile
• Lightweight Concrete tile roofs are produced from ALL natural products shale, cement, water and oxide. Tile roofs are recyclable and biodegradable at the end of their lifespan. Tile roofs are not plastic, resin, rubber or metal. Tile roofs do not warp, rust or bend. • Tile roofs are heavier than asphalt shingles.
