Measuring Roof Pitches

When measuring the roof from a 2D plan, create measurements that account for the angle/pitch of the roof, which can be saved as templates to use on other projects.

Step 1: Set up the measurements to reflect the pitch

When adding the length or area, create a measurement for each different pitch.

1. Create a Stage;
2. Click on + Length / + Area button to create a measurement;
3. Add in the measurement name including roof pitch e.g., Roof Area 23 Deg;
4. (optional) Add in pricing and select style options;
5. Click the blue Create button;
6. Repeat for all the different pitches on the project under this stage.

Once all the measurements have been added to the stage, measure the Length or Area as normal.

Step 2: Add the pitch calculations into the measurement

Account for the angle/pitch by adding a formula to the measurement:

1. Click on the Worksheet tab;
2. Jump to the correct stage (if required);
3. Click onto the measurement;
4. Click on the Formula e.g., Len;
5. Adjust the formula within the measurement e.g., len *1.0863 for a 23 degree roof pitch;
6. Click the Save button.
7. Repeat for additional measurements and parts.

Reference for Roof Pitch and Multipliers

Here's our Roof Pitch Chart to assist you with common Roof Pitches, Angles and their corresponding multipliers.

If you know the roof pitch in degrees, find the secant of the slope using a scientific calculator. For example, if the roof pitch is 26°, then sec(26) = 1.1126019404753957. That's your roof pitch multiplier.

Step 3: Save these measurements to use on other projects

Create Take-off templates from your stage to use these measurements with the formulas applied on other projects.
