Roof trusses are required every 24 inches on center. To determine the number of trusses, measure the entire roof’s slope in feet and divide by two, then round up to the nearest whole number to secure proper support. This calculation guarantees complete structural integrity and accommodates additional trusses for overhangs or complex roof designs while strictly following manufacturer specifications.
Truss size depends on your roof’s span and pitch. The pitch is calculated by how many inches the roof rises vertically for every 12 inches it extends horizontally (e.g., a 4/12 pitch rises four inches for every 12 inches of width). The span is the width of the truss from one end to the other. Larger spans need bigger trusses, which are more expensive.
Roof truss installation takes a full day when a proficient team of three professionals is engaged. The installation process follows a strict sequence that uses precise coordination and specialized equipment to align each truss securely with manufacturer guidelines. This efficient methodology ensures a completed roof structure that meets all quality and safety standards without compromise.
