Abstract
As the name implies, a hybrid roof system combines plywood sheathing and wood sub-purlins supported by open web steel joists and joist girders. Hybrid roof systems offer a more sustainable alternative to metal deck systems. In addition, depending on the market, hybrid roofs can be more cost-effective and faster to build than metal deck roofs. This article investigates hybrid roofs under light to heavy uniform and non-uniform snow loads throughout the Mainland U.S. Sheathing thickness, rafter size, and rafter spacing are adjusted accordingly to provide adequate strength and stiffness. The findings are presented in color-coded maps, enabling owners, architects, and engineers to make instant and accurate decisions.
