Roofing Measurement & Geometry Calculators

Calculate true sloped roof area from footprint dimensions and pitch. Results in square feet, square metres, and roofing squares.

Enter rise and run to find pitch ratio, angle in degrees, slope percentage, and pitch multiplier.

Convert roof square footage to roofing squares with adjustable waste factor for accurate material ordering.

Bidirectional converter between pitch ratio, degrees, and percent slope. Includes common pitches reference table.

Calculate four-slope hip roof area, ridge length, hip rafter length, and material estimates.

Standard two-slope gable roof area with ridge length, overhang factoring, and material estimates.

Barn-style double-slope geometry calculator with dual pitch angles and material requirements.

French-style four-sided double-slope calculator with upper and lower area breakdown.

Single-slope calculator for sheds, carports, verandahs, and ADU/granny flat additions.

Multi-section calculator for L-shape, T-shape, and U-shape homes. Add sections with different roof types and pitches.
