 View Saved (0)

Purpose:

Low-slope vented wood-frame membrane roofs are widely used in British Columbia but often struggle with durability and moisture issues in the coastal Pacific Northwest climate, even when built to code. Effective strategies for both new construction and renewal are essential to ensure long-term performance and resilience. This bulletin offers practical guidance for owners, designers, and contractors, drawing on findings from a recently completed Low-Slope Vented Wood-Frame Roof Study.

Impact:

Builder Insight is a series of bulletins and companion videos that provide practical information on new technologies, research results, good building practices and emerging technical issues in residential construction to Licensed Residential Builders and others in the industry.
