We recently consulted on a gem of historic architecture - a 1920s medical center in North Central Pennsylvania. It was an optimistic time, and the original donor mandated that "the structure last 300 years." His architects used the most time-proven materials money could buy. Today, the building - a city block's worth of granite, exquisitely decorated terra cotta, and bronze windows - does not look much the worse for wear.

Here are some key requirements for long-lasting clay tile roofs. Read more.
