Screw counting for screws purchased separately

Sheet Closure: Use U-Profile to close lower edge of roof sheets (see Eave Detail Options) and the Lower Edge of wall sheets. Lean-To Ridge, Freestanding Ridge and end wall sheets (See Roof Corner) must have aluminum tape at upper edge. This procedure will eliminate the possible entrance of dust, dirt and insects into the sheet channels. When U-Profile is used at lower edge of wall sheets and lower edge of roof sheets, a 1/16″ weep hole is required, every 12″ along the lower edge of the U-Profile, for moisture release.    U-Profile Install Tips
