Abstract
A methodology presented for an integrated analysis of roofing systems is used to assess different flat roofing systems in Israel. This approach can help designers with integrating technology issues, performance management and life cycle costs for component systems. The performance and durability survey observed an overall premature failure rate of 30%. The principal cause of failure was poor maintenance and inappropriate use. Life cycle costing analysis indicated that polyvinyl chloride membranes offered the highest life cycle costing effectiveness within Israel, primarily because of low maintenance expenditures. Despite its low initial capital investment, the single-layered modified bitumen roofing system exhibited high life cycle costs due to its short service life and consequent replacements costs.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
