Use Pitch to determine material needed for
roofing, proper vents & flashing for a roof, and paint and siding for
gable ends.
|
Ridge
Method
With the center bar of
the Quick Angle pointing up, lower both wings to
touch the roof on each side of the ridge. Read the pitch on the
center bar. |
|
Horizontal Method
- With the bottom wing level and the
top wing against the soffit or rafter, read the pitch on the center
bar.
- Place the bottom wing on the slope of the
roof and level the top wing. Read the pitch on the center bar.

Under the Ridge Pitch
- Open the Quick Angle to approximately
zero (0) degrees and slightly tighten the knob.
- Tie the Quick Angle to broom stick
or pole or 3/4" 200PSI PVC pipe.
Do not climb on a ladder or the roof!
|
|
Push the Quick
Angle to the center of the ridge peak.
- Read the degrees on the scale side of the
Quick Angle.
- Invert to the same degree on the upper end
of the scale.
- Turn over and read pitch.

To find Square
Feet for Material for a Roof
-
Measure Pitch using the easiest
method.
-
Multiply the Length x Width
of the roof.
-
Using this table, multiply
the figure from Step #2 by the number listed beside the pitch
of your roof.
4/12 pitch = 1.054
5/12 pitch = 1.083
6/12 pitch = 1.118
7/12 pitch = 1.157
8/12 pitch = 1.202
9/12 pitch = 1.250
10/12 pitch = 1.302
11/12 pitch = 1.356
12/12 pitch = 1.414 |
|
Vertical Pitch
|
You must remember to add extra for
the length of the overhang.
