Upside down roofs

To obtain a copy of a specific publication, users should contact the publication's publisher directly.

Abstract
The CRCA acknowledtges the seeming inherent advantages to the "upside down roof" as opposed to the conventional roof. The association would, however like to caution against too rapid acceptance for general use of a system not yet proven in practice and to rapid condemnation of a system which has, despite some often highly publicized failures, given good service over many years under varying Canadian climatic conditions.
