Roof Pitch Calculator
Calculate roof pitch ratio, angle in degrees, and slope percentage
Roof Pitch Standard: Roof pitch is expressed as $\text{Rise} : \text{Run}$ (typically per 12 inches of horizontal run). Common residential pitches include $4/12$, $6/12$, and $8/12$.

⚠️ Roof pitch requirements determine appropriate roofing materials (e.g., low slopes below 3/12 require specialized membrane roofing instead of standard asphalt shingles).
