.. -,\<, L !f ~ < . , , . .- . - . Pipe Boots provide a water tight seal around roof vents and come in a variety of sizes. Boots seal with caulk or butyl tape and conform to the shape of the metal panel ribs. Roof Pitch A TF AS panels require a specified degree of pitch to ensure proper water drainage. The minimum roof slope recommended for all panels is 3 inches of rise per foot. If the slope of the roof is below a 3/12 pitch, contact our representative before using metal roofing less than a 3/12 pitch. Florida Building Code requires a minimum of a 3/12 pitch. 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 form ridge to eave. Place a 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. Make sure that the metal panels are correctly side-lapped. In applications where end-lapping is required, the upper panel on the slope should lap over the panel that is lower on the slope. Lower roof pitch requires a greater amount of panel overlap. All end-lap applications require two horizontal rows (across the panel) of butyl sealant tape and proper fastening to ensure a maximum water seal application, Providing an overhang of 2 to 3 inches is recommended to provide a drip edge, although only a 1-inch overhang is required where gutters are used. The open metal 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 inside closures.
