5 tips for specifying cool metal roofs

摘要

Metal roofing has a reputation for being durable—both low-and steep-slope systems can remain operational for 30 years or more. But today's systems also meet increased demands for energy efficiency, says Scott Kriner, technical consultant with the Metal Initiative, Glenview, Ill. Through the proper selection of surface finishes, metal roofs can have higher levels of solar reflectance and infrared emittance, resulting in lower surface temperatures, says Kriner.
