description The utility model relates to a double-layer waterproof noise-reduction thermal insulation sound-absorbing metal roof. A traditional metal roof system adopts that thermal insulation cotton and a metal plate are directly installed on a steel structure, and has only one thermal insulation layer and a waterproof layer, and is poor in thermal insulation and waterproof properties. The double-layer waterproof noise-reduction thermal insulation sound-absorbing metal roof comprises a lower primary steel structure (1) which is connected with a primary purline (3) through a primary purline supporting member (2), a perforated contour plate (4) and a reinforcing rib pipe (5) are installed on the primary purline, a non-woven fabric dustproof layer (6) is arranged on the perforated contour plate, and a sound-absorbing cotton layer (7) is arranged on the non-woven fabric dustproof layer. The primary purline is connected with an auxiliary purline (10) through an auxiliary purline bracket (8), a galvanized steel wire net (11)
