Primary aerodynamic classification
Plan geometry for steep-slope roofs
Why provide precise slope? Enables accurate ASCE 7-16 GCp coefficient lookup across all slope ranges (≤7°, 7-20°, 20-27°, 27-45°).
Common pitches: 2:12 ≈ 9.5° | 4:12 ≈ 18.4° | 6:12 ≈ 26.6° | 8:12 ≈ 33.7° | 12:12 = 45°
Default: C (Open terrain with scattered obstructions)
Default: II (Most residential and commercial buildings)
Default: Enclosed (Standard building enclosure)
Default: ASCE 7-22 (Latest edition)
