TL;DR
A roof truss is a factory-engineered triangulated frame of dimensional lumber joined with pressed metal connector plates, designed to span between exterior walls and carry the roof without interior bearing walls. Trusses arrive sealed by the manufacturer's engineer, set on 24-inch centers, and must never be cut, drilled, or notched in the field without an engineered repair.
What it means
A roof truss is a factory-engineered triangulated frame of dimensional lumber joined with pressed metal connector plates, designed to span between exterior walls and carry the roof without interior bearing walls. Trusses arrive sealed by the manufacturer's engineer, set on 24-inch centers, and must never be cut, drilled, or notched in the field without an engineered repair. Their webbing fills the attic space—the trade-off against stick framing—although attic and scissor profiles buy back room or vaulted ceilings.
