SUBSTRATE PENETRATIONIn warm weather and tropical climates, red rosinpaper should be applied over the felt paper toprevent the felt paper from sticking to the panelsand tearing the vapor retarder. The red rosin paperwill allow for better thermal expansion. In coldweather climates, it is recommended that you usean ice and water shield at the valley and eave. Thisneeds to be applied over the substrate before theunderlayment is installed.ROOF SLOPE FACTOR .08331.11801.1180HIP/VALLEYSLOPEROOFSLOPE 60081.64151.64151.68531.68531.73201.7320NOTE: This chart to be used as a quoting guide only.

Multipleuses of this system may be required to determinebuilding squareness. If the endwall cannot be madesquare the roof system cannot be installed as shownin these instructions.Method A – One method for checking the roof forsquareness is to measure diagonally across oneslope of the roof from similar points at the ridge andeave and obtain the same dimension.Method B – The 3-4-5 triangle system may also beused. To use this system, measure a point from thecorner along the edge of the roof at a module ofthree (3). Measure a point from the same corneralong another edge at a module of four (4).

PANEL INSTALLATION OVERVIEWFamiliarize yourself with all installation instructionsbefore starting work. Before beginning installation,you should examine the substrate or framing toensure that all supporting members are straight,level, and plumb to avoid any panel distortion.Substructures should be designed to meet allnecessary code requirements.Some field cutting and fitting of panels and trimsis to be expected by the installer and minor fieldcorrections are a part of normal installation work.It is the responsibility of the installer to ensure asuitable substrate prior to the application of HorizonLoc. Underlayment must be nailed or stapleddown. Distortion in the panel caused by an unevensubstrate, ripples, or laps in the vapor barrier, debris,protruding nails and staples, button cap nails, etc.,are not defects in the materials and are not theresponsibility of Central States Manufacturing.All trims, closures, and accessories shown on theinstallation drawings are available from CentralStates Manufacturing unless noted otherwise.Oil canning in the flat area of the panels is commonto the industry and does not affect the integrity ofthe panel. Therefore, oil canning is not a reason forrejection.The panels should be installed plumb, straight, andsquare to the eave. To keep the bottom edge of theroof perfectly straight and even, the panels mustbe installed square to the bottom edge. Begin bychecking the roof for square; if it is square, you maypull the layout marks directly from the edge of therake.If the roof isn’t perfectly square, install the first panelparallel to your square line, making sure that the firstrib does not hang over the gable edge of the roofsheathing. (Any overhang can prevent the gabletrim from fitting tight against the rake.)NOTE: Copper metallic panels must be installedin the same direction! See directional arrows orstickers provided with your metal panel orderduring the panel installation process.TRIM INSTALLATION OVERVIEWOn runs of more than 10' 2" that require more thanone length of trim, overlap the pieces by 2". Thematerial is thin enough that the overlaps are notnoticeable. Trim is attached with rivets or gasketedscrews; take care to drive the screws enough toflatten the neoprene washer but not enough todeflect the roofing or the trim.The tricky part is finishing the ends of each trimrun. It may take a bit more time, but cutting andfolding the ends of the trim will give the roof amore finished look.When hooking the hem, measure over on hem3" from end of trim piece. Cut hem 1/8" up fromthe bend to 3" mark. Cut off back of hem. On lappiece, open up hem with screwdriver. Insert piece.Slide together. Use rivets and sealant on lap whereneeded.Remove strippable film from panels and trims beforeinstallation.Strippable film on Textured panels and trim must be removed within 30 days ofmanufacture date. Strippable that is left on for more than 30 days may be hard to peel offand is not a reason for a refund or replacement from the manufacturer.C E N T R A L S TAT E S M A N U FA C T U R I N G , I N C .Effective 01/2022 Information subject to changeCAUTION7

PANEL INSTALLATION1. Align the female edge of the first panel with thechalk line that was snapped at the rake edge. Thisline can be 0" – 1 3/4" from the rake. Panel shouldoverhang eave 1 1/2". See Figure 1.4. Align the second panel female edge with thestarter panel male edge. See Figure 2. Panels mustbe flush to one another. Remember, panels shouldextend over eave trim by 1 1/2".2. Panels should be installed perpendicular to ridgefor ridge trim attachment. Check panel alignment.If panel is properly aligned proceed to step 3.5. Lightly compress and snap panels together atseam. Snap panels from eave to ridge. Screw thesecond panel in place using 1" low profile waferhead screw in the male edge fastening flange.3. Attach rake edge to roof with a 1" paintedneoprene metal to wood fastener spaced at 48"on center. Then fasten the panel along the maleedge fastening flange with 1" low profile waferhead. Special care has to be taken not to overdrivethe screws in the male edge fastening flange.The screw flange is slotted to allow for slightpanel movement during normal expansionand contraction. To avoid panel distortion and toallow for maximum expansion and contraction ofthe panel, the screws should be snugged againstthe flange, but not so snug that the flange deflectsunder the screw head. To allow for movement ofthe panel towards the eave or ridge, place thefastener in the middle of the 5/8" slot. See fastenerspacing on page 4.6. Continue to apply panels as in steps 4 and 5.7. Panels at the eave can be terminated in twoways, with fasteners or without. Each will dependon aesthetic consideration determined by theinstaller or building owner.FIGURE 11" WAFER HEAD SCREW8C E N T R A L S TAT E S M A N U FA C T U R I N G , I N C .Effective 01/2022 Information subject to change

EAVE TERMINATION WITH FASTENERSPanels can be fastened along the eave with a #10 x 1" painted neoprene metal to wood fastener. Use butyltape under the panel. Fasten along a line parallel to the eave edge and 3" up from the eave edge. Thefasteners can be spaced 4" apart in the minor rib striations as shown in Figure 3.1" METAL TO WOOD SCREWHORIZON-LOC BUTYL TAPEFIGURE 3EAVE TERMINATION WITHOUT FASTENERSPanels can also be terminated with a hemming toolto provide a smoother appearance. When using thedrip edge condition to terminate the eave, panelsmustbe ordered 2" longer than your eave length toHORIZON-LOC account for the drip edge lip and the panel’s hem.STEP 1: Create a tab in the panel by cutting a notch in both sides of the panel. Cut through the male and femalelegs/ribs 1" up from panel end. Then cut on inside of major ribs with metal shears. See Figure 4.HORIZON-LOC FIGURE 4STEP 2: Place the hemming tool over the newlycreated tab in the panel as shown in Figure 5.STEP 3: With the hemming tool bend the tab downand under to 180 as shown in Figure 6.HORIZON-LOC FIGURE 5HORIZON-LOC FIGURE 6STEP 4: The panel is then ready to be installed over the Drip Edge trim, using the lip on the Drip Edge trim to securethe panel in place at the eave as shown on page 10.C E N T R A L S TAT E S M A N U FA C T U R I N G , I N C .Effective 01/2022 Information subject to change9
