Abstract
The concept of life expectancy in the context of built-up roofing is discussed. A simplified mathematical model is used to determine the characteristic fatigue endurance envelopes for selected built-up specifications. The major technical benefit afforded by the use of polyester-reinforced roofing is a marked increase in the life expectancy and/or a greater tolerance to amplitude of suvstrate joint movement. Both life expectancy and joint movement capabilities contribute to the durability of the roof covering.
