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 roofings is a marked increase in life expectancy and/or greater tolerance to ampliduted of substrate joint movements. Both life expectancy and joint movement capability contribute to the durability of the roof covering.
