Plywood Roof Sheathing Stick

Most of the time we just snap a chalk line down the hip rafter to cut the plywood roof sheathing. However, when the roof slope angle is steeper than an 8:12 pitched roof, 33.69007°, we will cut the plywood roof sheathing that attaches to the hip or valley rafter on the ground.  The easiest way to make an Roof Sheathing Stick is to lay the first plywood sheathe across the hip rafter and lay a stick parallel with the hip rafter and drive two nails next to the hip rafter.   AKA -- Okie Roof Stick,  something my father taught me. No math, just a couple of nails.







To make an Roof Sheathing Stick on the ground you can use the plywood cut off dimension, included in both of my Android and iPhone RafterTools apps. Simply mark off the plywood cut off, offset, dimension and snap a line for the plywood sheathing diagonal. Then lay a stick next to the diagonal line and drive two nails next to the edge of the plywood.

You can also use a framing square to layout the roof sheathing angle on the plywood using 12" and the length of the common rafter per 12" of run. Not very accurate on a 48" wide piece of plywood, but it works.



Math or Trigonometry for the Roof Sheathing Stick.


For Unequal -- Irregular -- Bastard pitched roofs.

Sheathing Angle = arctan(tan(Plan Angle) ÷ cos(Roof Slope Angle))
Plywood Offset Dimension = 48 / tan(Sheathing Angle)
Roof Sheathing Stick (Diagonal) = 48 / sin(Sheathing Angle)


For Equal Pitched Roofs:
