被风掀下一块可以杀人于无形。风大的地区应该不好不适合。还有金属导热快，冬冷夏热是免不了的，夏天万一要上roof维修还有烫伤的危险，夏天摸摸你的车子。遇上雷电那就更过瘾了。

看看下面wiki的解析

Advantages
Very durable in cold weather
High percentage of recycled material and are 100% recyclable
Disadvantages
Rusting (require maintenance to prevent corrosion)
Copper and lead roofs can be targeted by metal thieves
High heat conductivity of metals (particularly copper and aluminum) requires careful incorporation of insulation into the roof structure
Cellular and radio reception may be negatively impacted

據說很好可以延長屋頂使用時間，就是貴。

that is not my major concern, the hail won't last long, but other issues bother me such as cell signals, conductivity, etc.
