Roof Pitch Calculator & Gauge

Roof Pitch Gauge & Calculator is a practical roofing tool for measuring roof slope and handling common pitch calculations in one app.

Use your phone’s motion sensor to check roof angle and pitch directly on a sloped surface. Choose Flat, Long Edge, or Short Edge measurement mode depending on how your phone is positioned, then calibrate the selected mode for more consistent readings. You can hold, save, share, or hear a measured reading aloud when needed.

When direct phone placement is difficult, Camera Gauge provides a visual way to align a guide with a visible roof edge and estimate its pitch.

The built-in roof calculators help with everyday field calculations:

• Convert roof pitch, degrees, slope percentage, pitch factor, and rise/run
• Calculate roof rise from building span or horizontal run
• Find horizontal run from a known rise and pitch
• Calculate rafter or slope length from run and pitch
• Include horizontal overhang in slope-length calculations
• View common roof pitch reference values

Saved readings can be organized into Jobs with roof sections, photos, locations, client details, and notes. Job information can also be shared as a summary or exported as a PDF report. Selected roof photos can be shared with pitch and angle information added to a generated copy.

Additional tools include smart pitch snapping, adjustable display precision, measurement placement guidance, recent readings, light and dark themes, and calibration controls.

Roof Pitch Gauge & Calculator is useful for quick roof measurements, pitch conversion, rafter checks, and keeping roofing measurements organized while working in the field.

Camera Gauge is intended as a visual estimate. For measurements where higher repeatability is important, use a calibrated sensor measurement and appropriate professional measuring procedures.
