Finding roof pitch with a rafter square
What happens here
To measure the roof pitch, first hook the rafter square onto the lower edge of the roof. Ensure that the straight edge of the square is flush against the roof's fascia or drip edge. Next, slowly rotate the rafter square until the bubble in its built-in level is perfectly centered, indicating that the tool is level. Once the bubble is centered, identify the point on the rafter square's 'common scale' where the roof edge aligns. The video shows the reading at '4', which signifies a 4/12 roof pitch, meaning the roof rises 4 inches vertically for every 12 inches horizontally.
Goal: Determine the roof pitch using the rafter square's level and common scale
