present invention in a preferred embodiment steel trusses manufactured by steel con u2122 are used in a preferred embodiment angle clips 462 which have been designed to withstand extreme uplift forces are used to attach the trusses 460 to the header 450 by self tapping steel screws 464 or other similar fasteners furthermore because of the load distribution created by the spacing of the columns the trusses 460 can be spaced much further apart than in prior art systems reducing the amount of trusses 460 needed in a preferred embodiment the trusses 460 are place 4 feet apart from center compared to spacing the trusses 460 2 feet from center as commonly done in the prior art having wider spaces between the trusses 460 also makes subsequent procedures such as installing insulation further described below easier to accomplish roof panels may then be attached to the trusses 460 to form the roof of the building in a preferred embodiment 22 gauge roof panels are used installed in a horizontal and staggered fashion the rest of the building may then be finished as desired by the builder for example in a preferred embodiment an overhang for the roof is formed by inserting 1 inch u00d7 3 inch steel tubing into the open ends of the trusses 460 cut to the proper pitch and adjusted to the proper length to create the desired overhang and then connecting them together around the perimeter of the roof using a steel sub fascia a fascia may then be applied in a preferred embodiment insulation is sprayed on the interior of the roof as well as on the walls and floors of the building in a preferred embodiment the insulation is provided by icynene u2122 this greatly improves the insulation.
