Understanding Roof Pitch
Roof pitch is expressed as rise/run. A 4/12 pitch means the roof rises 4 inches for every 12 inches of horizontal run. Steeper roofs require more shingles due to increased surface area.

Shingle Calculation Formula
Squares = (Length × Width × Pitch Factor) ÷ 100
The number of shingle squares is calculated by determining your roof’s surface area, adjusting for pitch complexity, and dividing by 100 (since one square covers 100 sq ft).
