have a tendency to leave hot metal particles that can bum paint surfaces or leave rust marks on panels and trim. Likewise, any particles left on the roof caused by the application of screws must be removed. Care should be taken to remove all loose particles from roof surfaces after application. To cut panels lengthwise: Note carefully where the panel is to be cut, and, using a straightedge, score deeply down the length of the panel with a sharp-pointed utility knife. Folding the panel along the score mark, and bending back again if necessary, should produce a clean break in the panel. Ordering Roof Panels and Screws Care should be taken when ordering metal panels that correct length measurements are stated to avoid having to take corrective measures after purchase. Panel lengths should fall 2 to 3 inches short of the ridge when a vented ridge is desired and should extend 2 to 3 inches past eave to allow a sufficient drip edge (except concerning gutters). The ATFAB sales personnel are ready to assist customers with information specific to their particular metal roofing needs. Specially-washered screws applied through the flat of the metal is the recommended method used to attach metal roofing panels. 1-inch screws can be used if penetration of only % inch is either necessary or desired; otherwise, #9 x 1-% inch screws are recommended for metal to wood application. 2- ~ inch screws are also available, and are often applied by installers who hold to through-the-rib fastening, and for ridge-cap application. Ordering and Applying Trim Common flashing for metal roofing is the ridge cap, which is applied at the peak of a roof where two opposing roof slopes join. Other flashings include transition flashing, end wall, sidewall flashings and valleys. Eave flashings include gable flashing and eave drip, which are commonly applied above fascia trim. For a roof pitch exceeding 5/12 (a 5 inch rise in 12 inches), the slope of the roof should be specified upon ordering ridge caps, endwalls and eave drip. Verify local code requirements. Both slopes should be specified when ordering transition flashing if a steeper roof slope meets a lesser slope, At the gable edge, the use of gable trim adds to the appearance of the structure and protects the fly-rafter, and a sidewall flashing is used where the side of a panel butts up against an adjacent wall. In both instances, the installer/contractor should be careful to seal between the gable rake or sidewall and panel with butyl
