摘要

This invention provides a new roofing system for protecting flat roofs or slightly sloped roofs. This invention also features a method of roofing and a method of reroofing using a new roofing system, said method comprising:PP(a) removing and relocating debris, including but not limited to leaves and loose roof gravel, from top of a building;PP(b) using an existing horizontal roof deck as a lower surface of said new roofing system;PP(c) fastening a horizontal roof support to said horizontal roof deck, and to any ceiling joists lying under the horizontal roof deck, using fasteners; PP(d) fastening metal sheets to the horizontal roof support using fasteners, said metal sheets inclining upwards from a number of longitudinal outer edges of the lower surface towards a central section of the new roofing system forming a left upper surface and a right upper surface, with a gap existing at the central section between the left upper surface and the right upper surface of the new roofing system;PP(e) using a number of ridge caps to cover said gap at the central section which is located between the left upper surface and the right upper surface after having placed a number of two- way vents for transmission of air and moisture on the lower surface and at the central section of said new roofing system;PP(f) setting air conditioning compressors above metal sheets after supplying additional support under said air conditioning compressors and above said metal sheets;PP(g) sealing existing functional vents, and additional vents that are needed, to the metal sheets at the left upper surface and at the right upper surface of the new roofing system; and PP(h) attaching prefinished compatible metal gutters to a number of outer edges of the new roofing system such that said metal gutters surround the metal sheets and, thus, the building above which said metal sheets are installed, utilizing a number of down spouts when appropriate and supplying a number of new down spouts when needed and connecting said number of down spouts to the metal gutters.
