FORMERLY KNOWN AS TUFF-RIB SUPPLY & MANUFACTURING 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 Tuff 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 bum paint surface&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. CAUTIONI clean all metal shavings and particles"off of roof to.avoid unsightly rust stains • . i F�R�ERLY KN��N Ag��F�R/g t 4 S'ee pe �jal o !� 2.fOy .p1 U p p�l CY S�dZng 1'�ims & MA N U xA cTU R/NG -endN'alI v } ng r f (p e Fl dewacaU � �p:E � .

Gulf FORMERLY KNOWN AS TUFF-RIB SUPPLY & MANUFACTURING 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 attachroofing panels. 1-inch screws can be used if penetration of only 3/4 inch is either necessary or desired; otherwise, 1%2`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, whichis 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 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 11/2" (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. Besure 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. . . 7 / GULFRIB :: Gulf C5a FORMERLY KNOWN AS TUFF-R111 SUPPLY & MANUFACTURING Figure and Apply Screws screw urlin Spacing How to Fi g PP Y 1,2 inch._•18 inch 2.4 inch ' 0 501 270-' , 180 { 135 Gulf Coast Supply carries screws in 3 different lengths: 1 inch, 1% c 100, 540 360` i 270 inch, and 2 '/z inch. 1-inch screws will barely penetrate a 1x4,but the o '200 1080 ,720:1540 1'/z inch are the best all-purpose size. 1V2-or 2V2-inch screws are 300 1620 .1080 810 necessary for attaching ridge caps.

Figure 6_:Tuff;rib panel screw _ . Codes allow re-roofing over shingles without the use of battens calculation chart provided the roof has been checked by a licensed roofing contractor to insure levelness and pullout integrity. Tuff-rib metal roofing can be separated from the moisture barrier by minimum, nominal 1"x3" yellow pine battens spaced on maximum 24"centers, or according to ASCE calculations where applicable. Since direct contact between pressure treated lumber and metal roofmg must be avoided in order to prevent potential corrosion, Gulf Coast Supply sells only untreated battens. CAUTION: Battens must be fastened to the roof deck with minimum#6 screws at 12" on-center, or two minimum 8d common or pneumatic nails spaced 8" on-center, or one every 4" on-center(or by applicable calculations according to ASCE 7-98). Battens.must be installed to support the entire width and length of ridge, eave,hip,valley, and gable-end trims. For solid decking, at least 15/32-iuch structural plywood supported on rafters at a maximum of 24" on center is required. . If care is taken, metal roofing application can be aided by pre-drilling panels, allowing screws to go quickly and accurately into the desired spacing. Pre-drilling will work provided that pilot holes are placed accurately in the proper locations on panels. Purlin spacing must be uniform and carefully measured. For panel lap details, see Figure 5 on page 4. Gulf Coast Policies Delivery policy Delivery charges apply to all orders where delivery is requested. Please consult your Gulf Coast sales department for details. Sales tax All orders picked up at Gulf Coast Supply, and all orders delivered within the state of Florida, are subject to state sales tax.

Indemnity All prices and designs are subject to change.without notice Disclaimer While we have made every attempt at accuracy in this manual,we are not responsible for typographic, printing,or technical errors. Oil Canning--a repeating,wave-like appearance in the length of the panel—is.a common and often unavoidable phenomenon in metal panels like Tuff-rib roofing that have large,flat areas within the panel. It is therefore not a defect,nor a cause for rejection. See.p. 3 for details on how to avoid oil-canning. Return policy 'All panel orders and special order(non-stock);trim are considered the property of the customer and non-refundable once they are manufactured. Standard trim and accessories are refundable providing they are returned in a clean,resalable condition. Restocking charges will apply to any items at the discretion of the Gulf Coast representative.

GuZlf FORMERLY KNOWN AS TUFF-RIB SUPPLY & MANUFACTURING Ridge Cap 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 Ridge cap showing outside closure (left) and profile vent 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, F air-tight barrier. 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 may be 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%2 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.
