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.

Figure 6TtGulf)12ih'�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. Gulf 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 roofing 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-inch 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.

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. Tax exemptions should be verified prior to delivery or customer pickup. Warrantied products A 40 year warranty applies to most material* manufactured from painted coil stock, and a 25-year warranty to Galvalume material. Ask for details. 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 Gulf 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.

Standard trim and accessories are refundable providing they are returned in a clean, resalable condition.
