Proper cricket design.

Ponding water is the leading cause of premature roof system failure. Proper cricket design caneliminate ponding water and prolong roof system life.

CRICKET TERMINOLOGY

  • Roof Surface Slope The slope that is in the structural deck, the slope created by tapered insulation, or a combination of the two.
  • Cricket Width (Points C to D) Generally the shorter of the 2 cross-sections.
  • Cricket Length (Points A to B) Generally the longer of the 2 cross-sections.
  • Cricket Panel Slope The slope of the cricket panel.
  • Cricket Valley Slope (Points C to B) the net slope created along the edge of a cricket. (Cross-Slope).
  • Cricket Angle The angle (X) between corresponding lines AB (Cricket Length) and AC (Cricket Valley)

Design Guidelines

  • Cricket Panel slope is typically double the roof surface slope.
  • Depending on the roof surface slope, there is an accepted maximum length to width ratio.
  • The functionality of the cricket is determined by the cricket valley slope.
  • Cricket valley slope is independent of the cricket material slope.
