How do you figure roof rafters?

How do you calculate a roof?

Multiply your house length by your house width to get the area. (For example, 40 feet x 30 feet = 1,200 square feet.) Next, multiply the area by your roof’s pitch. (1,200 x 1.05 = 1,260 square feet.)

How do you calculate rafter length and Birdsmouth?

On the rafter, you want to cut, measure its overall depth, and divide it by 3. Using this figure, measure and mark two points on each side of the vertical line, which indicates where the birdsmouth will be cut.

What is the most common roof pitch?

The most commonly used roof pitches fall in a range between 4/12 and 9/12. Pitches lower than 4/12 have a slight angle, and they are defined as low-slope roofs. Pitches of less than 2/12 are considered flat roofs, even though they may be very slightly angled.

How do you measure a hip roof for shingles?

Climb up to the roof and measure each face of the hip roof. For parallelogram-shaped faces, measure the length of the bottom edge of the roof, length of the top edge (the ridge) and length from the ridge straight down to the bottom edge.

How do you measure shingles for a hip roof?

How do you calculate roof framing?

For example, if the slope is 4 in 12, and the run is 12 feet, the ridge beam height (M) will be 4 feet. The finished ridge beam height (Z) above the top of the wall will be (M) plus the Y Height. The formulas are: M = (R * X) / 12.

How are hip and ridge shingles calculated?

Just measure the length of the ridges and hips and divide by 35 to determine how many bundles of regular or hip-and-ridge shingles you’ll need.
