" But we don't have a metal roof."

“但我们没有铁皮屋顶呀。”

A wide, raised metal roof protects the building from rain and helps air flow.

宽阔凸起的金属屋顶可以保护建筑免受雨水的侵袭，并有助于空气流通。

In one town, a metal roof blew off of a business and landed between two homes.

在一个城镇，一家企业的金属屋顶被刮掉，落在两户人家之间。

The three- to four-bedroom homes take about three weeks to finish printing, with the foundation and metal roofs put in place with traditional building methods.

三到四居室的房屋大约需要三周时间才能完成打印，地基和金属屋顶则采用传统建筑方法安装。

As one does when facing the indisputable fact that there's nothing odd about a normal man without a metal roof getting through his corrugated iron at such a rate that it runs out.

就像在认可一个没有铁皮屋顶的人毫不费劲就把波形铁皮用完了这件事一点都不奇怪。
