Abstract
The performance of western hemlock, sugar pine, and western larch as alternatives to western redcedar (WRC) for roof shingles was investigated on outdoor roof racks with and without an initial brush or dip treatment with either pentachlorophenol (penta) or chromated copper arsenate (CCA). Untreated shingles of all species experienced degradation over a 32-year exposure in western Oregon, but WRC provided the best performance. Penta treatments improved performance to some extent, but the best protection was provided by a dip treatment in CCA prior to installation. The results illustrate the benefits of even shallow surface protection in aboveground exposures.
