What the AI looks for in Roofing Trusses

Engineered design: Trusses should come with sealed design drawings to ANSI/TPI 1 for your span, pitch, spacing and loads Snow, wind and dead loads are site-specific, and building departments require the truss drawings.
No field modification: Never cut, notch or drill chords or webs without a written repair detail from the truss engineer A single cut member can compromise the whole truss.
Bracing: Install temporary and permanent bracing per the truss drawings and BCSI guidance Unbraced trusses can domino over during erection and buckle under load.
Uplift connectors: Use hurricane ties or truss clips sized for the uplift loads on the drawings Toe-nails alone often fail in high winds.
Spacing and sheathing: Match truss spacing (commonly 24 inches on center) to the sheathing's span rating Overspanned sheathing sags and shingles telegraph the waves.

Simpson Strong-Tie: Standard brand for hurricane ties, truss clips and hangers.
MiTek: Major maker of truss connector plates and engineering software used by truss fabricators.

Building trusses are normally made to order by a local fabricator from your plans. Online you will mostly find connectors and hardware.
