The paint system employed on painted products offers optimum exterior protection plus superior resistance to corrosion and ultraviolet radiation. While bare Galvalume carries a 25-year limited coil manufacturer's finish warranty, most painted metal carries a 40-year war- ranty.

DETAIL MANUAL Installation of Panels Roof Pitch Gulf Coast roofing panels require a certain degree of pitch to ensure proper water. drainage. Florida Building Code allows a minimum pitch of 2/12 for Gulf Rib® panels as long as lap screws and sealant are applied to the laps to prevent water from siphoning over the ribs (see Fig. S on p. 4). Lap screws and sealant are optional when the pitch is 4/12 or greater (4/12 pitch means that there is 4 inches of rise for every 12 inches running horizontally). As a general principle, the less steep the roof, and the more necessary also that sealant be used at all side -laps. Consult our representative for recommendations for your particular roof pitch, and about roofing options if you have less than a 2/12 pitch. Roof Preparation Oil -canning is a wave -like, rippled appearance extending up the length of the panel after it has been installed on the roof. Any irregularities in the roof, including uneven plywood joints, warped plywood, uneven trusses, poor application of underlayment, the use of button caps with felt paper, etc., can promote oil -canning. Care should be taken to provide a flat, uniform surface on which to attach the panels. See page 6 for more details. Roof Application Panel installation should begin at the gable end of the roof opposite the prevailing rain -bearing wind (this will provide added assurance against wind -driven rain being forced under the laps). Measure one panel width in from the roof edge. At this point chalk a line from ridge to eave. Place the leading edge of the first panel along this line. It is extremely important that this panel be laid square to the eave and ridge so that the remaining panels will line up square on the roof frame. It is wise to have a person at the eave and at the ridge to ensure that the proper panel coverage is being maintained across the roof. Also be sure that the panels are properly side -lapped (see fig. 7 on page 7). In applications where end -lapping is necessary, the upper panel on the slope should lap over the panel that is lower on the slope by about 12 inches. Lesser roof pitches require a greater amount of panel overlap. All end -lap applications should use two horizontal rows of butyl sealant tape across the panel and proper fastening to provide a maximum water seal. An overhang of 2 to 3 inches on the eave is recommended to provide a drip edge, while only 1 inch overhang is necessary where gutters are used. The open panel ribs at the eave can be sealed with inside closures. For maximum weather -tightness, a row of butyl tape can be applied above and beneath closure material. Trimming and Cutting Steel Panels The best device for cutting steel panels across the profile is either hand snips or a nibbler. Nibblers, and especially Carborundum blades on electric saws, however, do have a. tendency to either leave hot metal particles that can burn paint surfaces or to leave rust marks on panels and trim. The same is true of any filings left on the roof caused by the application of screws. Care should be taken to brush all such 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. CAUTION! clean all metal shavings and particles off of roof to avoid unsightly rust stains Residential Trim Seep. 12 for Siding Trij trim \11) Sidewall Roll Lite Door Transition Flashing (p.10) Figure 4 Roofing trims and flashings are named' by the location or function, of that particular piece on the building.

On pitches greater than 3/12, lap screws and butyl tape are optional. For more details on screws, see pgs. 6 and 7. GULF ,RIB''" DETAIL MANUAL Ordering Roof Panels and Screws Care should be taken to order panels of the correct length to avoid having to make 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 the eave to allow a sufficient drip edge (except as noted on pg. 3 concerning gutters). When a roof transition is involved, panels of the upper portion should be ordered short to allow placement of the transition flashing (see diagram -on p. 10). 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. 1-inch screws can be used if penetration of only 3/a inch is either necessary or desired; otherwise, 1% inch screws are usually recommended. 2%2 inch screws are also available, and are often used by those who adhere to through -the -rib fastening, and for ridge -cap application. See pages 6 and 7 for more information on screw spacing and ordering. Ordering and Applying Trim 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 trims include gable flashing and eave drip, either 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 rake 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 should be specified separately from that used on the drip edge when ordering. To prevent penetration of water, insects, and debris at the ridge, outside closures should be inserted between the ridge cap and the;top end of the panel. Screws are applied through the ridge cap, closure, and rib in at least every other rib of the panels. At least a 1 %z" (or preferably 2%2") screw should be used for attaching ridge caps. Self -drilling lap screws can also be used to attach 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.

The Ridge Cap is used to seal the point at which two upward slopes meet. This can be both along the ridge of the roof as well as a covering for a hip. Either woodgrip or self -drilling lap TEK screws are applied through the ribs of the metal. Since debris, insects, and blowing rain can find easy access under the ridge cap, closures are required to either completely or partially seal the opening. Closures under ridge caps come in 3 types: solid, vented, and hip tape. Figure 9 Solid closures ("Outside Closures") are (right). the same width as the panels. They lock together in a row placed directly under the screws that attach the ridge cap, and form a solid, water -tight, air-tightbarrier. Profile Vent® comes in 50 foot rolls, is 3 inches wide, and forms a water - retardant, insect resistant barrier that allows hot air to escape from the attic, and is superior to many more elaborate and expensive vent systems. Any length maybe ordered. Hip closure tape (Peel and Seal) is a sticky, adhesive -backed metallic tape that seals the hip roof. It is 6 inches wide and comes in 33'h foot rolls. Because it must be conformed to the rise and fall of the panel ridges, approximately 10% extra may be needed beyond the length of the hip being covered. - Outsi .close I screw required ent® •sa-Vent® RC-2 Standard 12-inch Ridge Caps are strong, economical and adequate for most of your roofing needs 6"__� RC-1 style 12-inch Ridge Caps are also available in custom widths Ridge cap showing outside closure (left) and profile vent Figure 10 Pipe Boots provide a water -tight seal around roof vents and come in a variety of sizes.
