The invention relates to a method for arranging profiled metal roof panels with free-form surfaces, which belongs to the technical field of building structure engineering and comprises the following operation steps of: determining the drainage direction of a roof by drawing a contour line of a building model, namely determining the direction of roof panel arrangement; then, making a vertical projection of a first roof panel on the building model to obtain a first auxiliary curve; making a first geodesic line of the building curved surface through the starting point and the terminal point of the first auxiliary curve, and obtaining the starting line of the first roof panel of a hyperbolic building metal roof. allowing the plate width of the metal roof panel to be L, and enabling the metal roof panel to deviate from a first roof panel starting line on the building model with the deviation distance of L to obtain a second auxiliary curve. and finally, establishing a geodesic line by adopting the auxiliary curve
