The roofing system is framed with engineered raised heeled trusses. The use of raised or cantilevered trusses allows for a greater depth of insulation over the exterior rim plate. The result is increased energy efficiency and reduced likelihood of ice dams. In addition, raised heel trusses facilitate the installation of bricks above the windows. This provides a more attractive exterior appearance.
Trusses are sheathed with ½" spruce plywood. (no chipboard is used). Standard shingle is 25-year asphalt. Lifetime Warranty architectural shingle is available as an upgrade
Six mil polyethylene vapour barrier and resilient channel are secured between the underside of the trusses and the ceiling drywall. Resilient channel is installed to eliminate cracks caused by truss uplift and to provide a smoother ceiling.
