About Roofing and Pergolas cost estimation
Roofing cost splits into the supporting frame and the covering over it. The frame follows the same weight-based pricing as other steel work; the covering is sold by area, and the sheet profile, thickness and coating set its rate.
Pitch, overhang and the number of supports change the frame weight substantially, so a plan area alone will not give a reliable figure.
