ABSTRACT: While there are an increasing number of outlets for information on building materials and
methods, particularly web-based ones, little published information is available on the suitability of
membrane materials for water collection. The microbiological aspects of roof materials and systems for
rainwater collection are well documented, thanks to ongoing study of those at the Wellington Massey
Roof Water Research Centre. Issues such as chemical leeching from materials however are far less
comprehensively studied. This paper examines existing information on the performance of membrane
roofs for water collection, identifies areas where such information is lacking, and suggests methods to
improve the quality and breadth of information available.
