InterNACHI inspectors should not call out a lack of collar ties as a defect unless they know that collar ties were required in the jurisdiction where the home is located at the time the home was built. They may or may not be required, depending on the jurisdiction.In high-wind areas, uplift can tear a roof off of a house if it's not properly attached.Ĭollar ties and ridge straps should be installed on roof with a minimum slope of 3:12, a maximum wind speed of 100 miles per hour, and a maximum roof span of 36 feet. They must be spaced no more than 4 feet (1219 mm) apart. They must be at least 1 inch by 4 inches (25 mm by 102 mm).
#Rafter vs truss series
is that rafter is one of a series of sloped beams that extend from the ridge or hip to the downslope perimeter or eave, designed to support the roof deck and its associated loads or rafter can be a raftsman while truss is a bandage and belt used to hold a hernia in place. If collar ties or ridge straps are installed to connect opposing rafters, they must be located in the upper third of the attic space. As nouns the difference between rafter and truss. Ridge straps are permitted to replace collar ties.

We often get asked what the standard size and pitch of a truss is as many people think they are an off the shelf product. Its a beam that stretches from a central ridge beam to the outer walls. Rafters require more labour costs and time, whereas trusses are manufactured offsite ready to be installed when they reach the site. A rafter is a traditional roof framing element.

Rafters need to be cut and constructed on site whereas a truss is a fully designed structure meant to be lifted and installed onto the roof. There’s often some confusion between trussed rafters and roof trusses and we want to try and provide some clarity about the differences. They are called ‘cold’ trusses because the area above the loft insulation leaves a large cold space in the roof zone.Ī warm roof truss, also referred to as an attic truss is where people live so the insulation on the truss is placed within the sloping top chord of the truss so there is a minimal void space above the insulation and the outside environment, hence the term ‘warm’ roof truss. These are our standard fink trusses and the loft insulation is laid directly above the ceiling. Cold roof trusses are most commonly used in new build houses.
