Roof System Components

All steep-slope roof systems (i.e., roofs with slopes of 25 percent or more) have five basic components:

  • Roof covering: shingles, tile, slate or metal and underlayment that protect the sheathing from weather.
  • Sheathing: boards or sheet material that are fastened to the roof rafters to cover a house or building.
  • Roof structure: rafters and trusses constructed to support the sheathing.
  • Flashing: sheet metal or other material installed into a roof systemís various joints and valleys to prevent water seepage.
  • Drainage: a roof systemís design features, such as shape, slope and layout that affect its ability to shed water.
