Abstract
In the years between 1950 and 1992, there has been little overall improvement in the life span of typical roofs. In fact, some old timers will argure that the roofs they installed in the 50's lasted longer than today's roofs. Why have we not seen improvements in roof life? Achieving more sustainableroofing is possible at very little incremental first cost and with total cost savings over just a few years. The examples cited in this reportshow how two of the most popular roofing systems could be improved with a small increase in cost, using currently available technology and skills.
