Abstract: 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. Its roof is covered with clay tiles, one of the oldest and most durable building materials.|Of course, such a timeframe far exceeds what reasonable designers will promise, but many institutions still expect their buildings to last for generations. Clay tile roofs, which can last 75 years or more, are frequently used on monumental buildings. On the downside, such roofs represent a significant initial investment that can be quickly destroyed by faulty design, workmanship, or materials. Here are some key requirements for long-lasting clay tile roofs.
