Panel lengths should fa112 to 3 inches short of the ridge when a vented ridge is desired, and should extend 2 to 3 inches past the eave to allow a sufficient drip edge (except as noted on pg. 3 concerning gutters). The Gulf Coast sales personnel are ready to assist customers with information specific to their particular roof. Specially-washered screws applied through the flat of the metal is the most recommended method used to attach roofing panels. 11/z inch screws are the commonly recommended length. 2'/z inch screws are available for ridge-cap application and other special needs. For attachment to metal purlins, a minimum of#12 x 1" hex head TEK screw or equivalent is recommended, and for stitching panels and trim to panels, we recommend#14 x 7/8" lap TEK self-drilling screws. See pages 6 and 7 for more information on screw spacing and ordering. Ordering and Applying �im The most common flashing for metal roofing is the ridge cap, which is used at the peak of a roof where two opposing roof slopes join. Other flashings include transition flashing, end wall and sidewall flashings, and valleys (see diagram on right for application). Eave flashings include gable f lashing and eave drip, both of which are often applied above fascia trim. When roof pitch exceeds 5/12 (a 5 inch rise in 12 inches), the slope of the roof should be mentioned when ordering ridge caps, endwalls, and eave drip. When a steeper roof slope meets a lesser slope, both slopes should be mentioned when ordering transition flashing. At the gable edge the use of gable trim adds to the appearance of the structure and protects the fly-rafter, and sidewall flashing is used where the side of a panel butts up against an adjacent wall. In either case, the installer should be careful to seal between the gable rake or sidewall and panel with butyl sealant tape, and to fasten the trim every 6" to 12" up the slope of the roof with the appropriate screws. If eave drip is used on the gable, the number of 90 degree eave drip for the gable should be specified separately from that used on the drip edge when ordering. To prevent penetration of water, insects, and debris at the ridge, either solid or vented closure material is inserted between the ridge cap and the top end of the panel (shown on p. 9). Screws are applied through the ridge cap, closure, and each rib of the panels. 21/z" wood screws or self-drilling lap screws should be used for attaching ridge caps. Keep Materials Dry! Paint and finishes of Gulf Coast panels and trim are designed to withstand severe rain and wet weather conditions. Neither paint, galvanized, or Galvalume finishes, however, are designed to be in continuous contact with water for long periods of time. Damage will result if uninstalled . panels or trim are allowed to remain wet in storage. Be sure to store material that will not be installed immediately in a dry location. Wet material should be air-dried and re-stacked if installation is not planned right away. (352) 498-0778 • 1'0ll Free (888) 393-0335 • FAX (352) 498-7852 - 5 -
