Hip Roof Calculator
Calculate hip roof dimensions, area, materials, and construction costs. Determine rafter length, roof pitch, and material requirements for your project.
Step 1: Roof Dimensions
Understanding Roof Pitch
Roof pitch is expressed as rise:run (e.g., 6:12 means 6 inches of rise per 12 inches of run). Standard pitches range from 4:12 to 12:12 for hip roofs.
Step 2: Materials & Cost
About Roof Squares
One roofing square equals 100 square feet of roof area. Materials are typically sold by the square, and waste factor accounts for cutting and errors.

Hip Roof Formulas
Common Rafter Length = √(Run² + Rise²)
To calculate rafter length: Use Pythagorean theorem where run is half the building width and rise is determined by pitch. Hip rafters are longer and calculated using diagonal geometry.
