5.12 PREPARING THE STEEL BUILDING EAVE
After installing the first run of steel building insulation, prepare the eave for the first roof panel by applying tape sealant along the eave outside of the insulation and leaving release paper in place. Sealant must be applied in a straight line and without voids. Do not stretch the sealant. Use a knife to cut if necessary. Cut an inside closure strip as shown and place starter piece on top of the sealant (removing protective paper from the sealant only as required). Align the major rib of the closure with the edge of the endwall roof line. Splice a full closure to the starting closure and apply along the top of the eave sealant. If roof is subject to ice and snow build-up, the splice in the closure strip must be caulked to insure weathertightness.
Along the top of the closures that have been placed along the eave, apply a second run of tape mastic. Prior to removing paper backing, check and mark for proper alignment of the first roof panel.Note that self-tapping screws will require holes be drilled in the supporting the steel building prior to installation. Continue mastic and closure run along eave in preparation for the next roof panel.
