[ p = q , G , C_p - q_i , (GC_pi) ]

For a gable roof building with a roof angle of approximately 18 degrees, for instance, the roof external pressure coefficients (GC_p) might be as follows: Zone 1 negative coefficient of -0.80, Zone 2 negative coefficient of -1.20, and Zone 3 negative coefficient of -2.00, reflecting the increased suction at roof corners and eaves. Positive coefficients for Zone 1 typically range around 0.30. wind load calculation as per asce 7-05

Note: The positive and negative values represent internal pressure pushing outward or pulling inward on walls and roofs, respectively. Both configurations must be evaluated.
