Begin by verifying the roof datum lines, then install the supports and fixing brackets. Lay down the insulation and waterproof underlayment. Hoist the metal roof panels into position according to the layout plan, secure them using a locked-seam (standing-seam) technique, and ensure that the panel joints remain straight and aligned. Properly execute the detailing for roof ridges, gutters, and flashings, and apply sealants at all junctions. Inspect the panel surfaces for flatness, ensuring there is no warping or leakage, and provide adequate protection for the finished installation.

Construction Steps for Structural Layers

Key Construction Requirements

1.The structural layers must be continuous and complete, with tight overlaps that meet design specifications.

2.The insulation layer must be laid flat, with no loose sections or gaps.

3.The waterproof layer must be reliably integrated with the metal roof panels to form an effective, watertight system.
