. � <br /> ROOF PITCH ' <br /> MET�4I, S�STEMS, INC. panels require a specified degree of pitch to ensure <br /> proper water drainage. The minimum roof slope recommended for all panels <br /> is 3 inches of rise per foot. If the slope of the roof is below a 3/12 pitch, <br /> contact our representative before using metal roofing on less than a 3/12 pitch. <br /> FLORIDA BUILDING CODE REQUIRES A MIIVIIVIUM OFA 3/12 <br /> PITCH. <br /> ROOF APPLICATION <br /> Panel installation should begin at the gable end of the roof opposite the <br /> prevailing ra.in-bearing wind (this will provide added assurance against <br /> wind-driven rain being forced under the laps). Measure one panel width in <br /> from the roof edge. At this point, snap a chalk line from ridge to eave. Place <br /> a leading edge of the first panel along this line. It is extremely important that <br /> this panel be laid square to the eave and ridge so that the remaining panels will <br />� line up square on the roof frame. It is wise to have a person at the eave and at <br />' the ridge to ensure that the proper panel coverage is being maintained across <br /> the roof. Make sure that the metal panels are correctly side-lapped. <br />' In applications where end-lapping is required, the upper panel on the slope <br /> should lap over the panel that is lower on the slope. Lower roof pitch requires <br /> a greater amount of panel overlap. All end-lap applications require two <br />� horizontal rows (across the panel) of butyl sealant tape and proper fastening to <br /> ensure a ma,ximum water seal application. <br /> Providing an overhang of 2 to 3 inches is recommended to provide a drip edge, <br /> although only a 1-inch overhang is required where gutters are used. The open <br />, metal panel ribs at the eave can be sealed with inside closures. For maximum <br /> weather-tightness, a row of butyl tape can be applied above and beneath inside <br /> closures. <br />� <br />� <br />
