This guide provides information on how to design and build simple roof structures for light weight and even (non-curved) roof cover materials. Although it is part of the FCR/MCR Toolkit series, it is equally applicable in the case of other roof cover materials such as clay tiles, slates, sheets etc.

The guide explains the basic principles of building statics and structural design. Constraints determining the roof shape and earthquake and storm proof construction are discussed.

The guide deals in brief with all the commonly known materials for roof structures with special emphasis on timber technology.

The guide is addressed to architects and engineers involved in the design of buildings with FCR/MCR tile roofs, and also to builders, site engineers and overseers, who are implementing construction.

Producers of roof cover materials can use the guide as a basis for advising their costumers on the successful use of their products. The guide is also useful as a teaching aid.
