Cricket slope set from the field slope, with manufacturer confirmation when needed.
Offline Android tool for low-slope roofing
Design your roof crickets and tapered layout, offline.
Drop drains, draw the bay, and CricketWright sizes the cricket, checks the valley slope, sequences the board stack, and counts the takeoff before the membrane crew starts.

One bay, one solved stack
Valley slope shown in inches per foot so the diagonal drain path is not guessed.
Cricket rows, field boards, flat fill, waste, and pallet estimate are counted together.
Export a cut-and-stack layout with the assumptions and disclaimer on the page.
Built for field judgment, not blind approval
CricketWright is a tapered-insulation layout aid based on NRCA/PIMA design practice and IBC minimum-slope rules. It is not a substitute for a manufacturer stamped tapered design, a licensed engineer, or your local code authority. Verify all slopes, board counts, and R-values against the manufacturer data and your AHJ before ordering or installing.
