Metal Roof Drain Detail Section with Pluvial Pipe and Joint Layout

This AutoCAD metal roof drain detail drawing presents a clear metal roof drain detail section showing the construction of a metallic roof with an integrated pluvial drainage system. The drawing illustrates the sectional arrangement of roof panels, roof edge flashing, structural supports, and the pluvial pipe connection used to manage rainwater flow from the roof surface. The metal roof drain detail section explains the relationship between the roof sheet layers, supporting structural frame, and the drainage outlet that directs water into the pluvial pipe system. Detailed joinery connections are shown at the roof edge where the metallic roofing elements meet the supporting wall structure and drainage outlet. These elements form a complete metal roof drainage assembly used in architectural roof construction.
