Repair of Historic Clay Tile Roofs

Jeffrey Havelin, PE

The purpose of this (One-Hour) course is to provide the architect or engineer with a fundamental understanding and a technical knowledge of historic clay tile roofs.

Historic roofs are being improperly repaired or replaced with alternative roofing materials, to the detriment of the historic integrity and appearance of the structure. Increased knowledge of the characteristics of historic clay tiles and its detailing and installation on the roof can lead to more sensitive interventions in which original material is preserved and the building's historic character maintained.

This course will review the history of clay roofing tiles and will include a description of the many types and shapes of historic tiles, as well as their different methods of attachment.

A complete internal and external inspection of the roof structure and the roof covering is recommended to determine condition, potential causes of failure, or source of leaks, and will help in developing a program for the preservation and repair of the tile roof. Before initiating any repair work on historic clay tile roofs, it is important to identify those qualities important in contributing to the historic significance and character of the building.

This course is based entirely on the web version of the National Park Service Preservation Brief 30 which is entitled “The Preservation and Repair of Historic Clay Tile Roofs” as published by the National Park Service- U.S. Department of the Interior.

This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of course materials.
