Abstract
Condensation in wood-framed parapets can result in water damage, mimicking low-slope roofing membrane and parapet cap leaks. Unfortunately, roofers have been erroneously accused of causing water leaks into buildings when these parapet “leaks” occur. These roofing installation claims often force roofers and others to spend countless hours probing roofing seams and making roof cuts in search of non-existent roof leaks. This technical bulletin discusses the potential for condensation and associated water damage within wood-framed parapets and ceiling cavities caused by the failure to control humidity build up within the parapet. It also outlines design features to include in wood-framed parapet walls to minimize condensation potential.
