What is a "Structural Roof System"?

A Light Gauge Steel Roof System consists of:

  • Light Gauge Steel Trusses
  • Truss Bracing
  • Truss Connections:
  • Truss to Truss, Truss to Structure
  • Roof Deck Assembly
  • Shear Transfer Framing
  • Eave Edge Structural Supports
  • Valley, Hip, and Ridge Structural Supports

These 7 Structural Elements form a “Roof System”!

What is required to meet the code?

The 7 structural elements of the “Roof System” must meet the following building code requirements:

    1. Light Gauge Steel Trusses
      • Support Vertical loads both up and down
      • Transfer lateral loads
      • Provide proper bearing for the deck i.e. avoid knife-edge conditions
    2. Truss Bracing
      • Prevent chord buckling
      • Prevent web buckling
    3. Truss Connections
      • Resist gravity loads
      • Resist wind loads
      • Resist seismic loads
    4. Roof Deck Assembly
      • Support both uniform and concentrated vertical loads
      • Act as a shear diaphragm resisting either seismic or wind loads
    5. Shear Transfer Framing
      • Collect shear and transfer it to the structure and the diaphragm chord below
    6. Eave Edge Structural Supports
      • Support concentrated and uniform loads at the roof edge
      • Collect shear from the roof deck
    7. Valley, Hip and Ridge Structural Supports
      • Support concentrated and uniform loads
      • Transfer shear across the roof deck transition planes

All 7 Items Must Meet Code Requirements!

If each of these 7 elements in your light gauge steel roof system has not been designed and certified by a structural engineer, then chances are:

Your Roof Won’t Meet the Building Code!

Our 7 elements will meet the building code!

We guarantee it!
