2 Thak you for choosig ONDURA-9 for your roofig project. ONDURA-9 should be carefully istalled. Mistakes i istallatio ca cause roof problems later o. Please take your time ad closely follow these istallatio guidelies. CAUTION Istallatio of roofig materials ca be dagerous. The relative amout of dager is icreased by the height from the groud, icreasig pitches of the roof slope, iclemet weather coditios or other factors. We strogly recommed for ayoe istallig ONDURA-9, or workig o a roof i ay maer, to take all precautios possible to esure your persoal safety at all times. Be sure that ladders ad other such devices are safely positioed ad properly secured. OSHA recommeds the use of a safety haress whe applyig roofig. Protective eyewear is recommeded whe applyig ails or usig power tools. ONDURA-9 may be slippery whe wet, dusty, frosty or oily, so please avoid workig or walkig o the roof if ay of these coditios exist. Widy coditios ca make the worksite more dagerous, so we recommed that you do ot attempt to istall ONDURA-9 durig widy coditios. ESTIMATING GUIDE FOR ONDURA 9 Sheet dimesios: 36 iches wide by 79 iches log Sheet Coverage For projects requirig multiple sheets, accout for overlaps i calculatig roof coverage (see diagram below). Sidelap should be at least oe corrugatio (4 iches per corrugatio). Headlap should be at least 7 iches. The effective sheet coverage is 32 iches wide by 72 iches log. Fasteers Fasteers eeded per sheet: 17 mi./24 max. for 3 rows of fasteers, with rows spaced approximately 24 iches apart. Fasteers for roof ridge: 6 fasteers per foot of ridge (3 o each side). Faste sheets o every corrugatio at rake edge, eaves, ad overlaps. For other fasteer rows you may faste o every corrugatio or o every other corrugatio. Fasteig o every corrugatio provides better wid resistace. Faste ridge caps at every corrugatio. Ridge Caps Ridge cap sectios should overlap by at least 7 iches. Closure Strips Closure strips are 44 iches log, with four strips per pack. Closure strips should be used at roof ridge ad eaves. 4 iches 7 iches tools ad MATERIALS You will eed the followig tools ad materials: Claw Hammer Utility Kife Saw (Had Saw or Circular Saw) Measurig Tape or Yardstick Strig Pecil or Marker Protective Eyewear 79 iches 2 36 iches

3 PLANNING STAGE Determie the Slope of the Roof The slope of the roof ca be calculated from measuremets of the rise ad ru of the roof. The rise is the vertical distace of the ridge above the eave. The ru is the horizotal distace of the ridge from the eave. A roof slope is ofte stated as the iches of vertical rise per 12 iches of horizotal ru legth. The miimum appropriate slope for a ONDURA-9 roof is a 3 ich rise over a 12 ich ru. Slope = amout of rise per ru Example: 3-i rise per 12-i ru = 3:12 Miimum slope required: 3:12 Roof Sheathig Roof sheathig is a plywood or OSB (orieted stradboard) layer o top of the roof supports. If your roof has sheathig, we recommed usig stadard felt paper or a ice water shield over the sheathig. Purlis Eave Slope Ru Ridge Rise If your roof has purlis istead of sheathig, the the maximum purli spacig is 24 iches o ceter. If your roof may be exposed to heavy sow loads, the the purli spacig should be reduced to 12 iches o ceter. Note: At the ridge of the roof, the gap across the ridge, betwee the upper eds of the ONDURA-9 sheets o each side of the roof, will be covered by the ridge cap; ad the gap should be o more tha two iches. If your roof is wider tha 36 iches, the you will eed to accout for the sigle corrugatio overlap for adjacet ONDURA-9 sheets. The first ONDURA-9 sheet will provide 36 iches of coverage. Each additioal ONDURA-9 sheet will provide 32 iches of coverage with oe corrugatio overlap. Rake Edge The rake edge of the roof should be covered to prevet water itrusio or damage to the sheathig. The rake edge should be covered with drip edge flashig. The drip edge flashig goes over the felt paper o the rake edge ad uder the ONDURA-9 sheet. Felt paper Drip edge flashig uder felt paper o eave Drip edge flashig o top of felt paper o rake O-Site Storage While stored at the job site, ONDURA-9 sheets must be covered to protect from damage that may be caused by raiwater trapped betwee sheets. Do ot allow stacked sheets to get wet while stored. Cuttig ONDURA-9 Sheets Always wear eye protectio whe cuttig. To cut a ONDURA-9 sheet parallel to the corrugatios, use a utility kife with a sharp blade. Always cut sheets i the valley of a corrugatio with the paited side up. Roof Coverage ONDRUA-9 sheets are 36 iches wide ad 79 iches log. We recommed a overhag at the roof eave of 1 to 1-3/4 iches (Note: 1-3/4 iches is the maximum overhag relative to the edge of the roof sheathig). Measure the roof from eave to ridge ad add the overhag legth to determie the total legth of coverage. To cut a ONDURA-9 sheet perpedicular to the corrugatios, use a circular saw with a carbide-tipped blade or a had saw. Apply a lubricatig oil o the saw blade to aide i a smoother cut. For best results, work with the paited side dow ad mark the cut lie with a pecil o the upaited side. If the total legth of coverage is greater tha 79 iches, the you will eed a secod row of ONDURA-9 sheets. The sheet overlap from row to row should be at least 7 iches. Cut through the valley with utility kife. 3

4 Placemet of ONDURA-9 Sheets If more tha oe row of ONDURA-9 sheets is eeded, the the sheets must be istalled alog the eave first. The additioal rows are istalled above the previous row. Each row should be istalled with the first sheet at the opposite ed of the roof from the prevailig wids. With this orietatio, the seam of the overlap will face away from the prevailig wids. This orietatio will reduce the possibility of wid-drive rai gettig uder the corrugatio overlap. If wid-drive rai could come from both directios, the we recommed sealig alog the overlap with a elastomeric caulk. INSTALLATION STAGE Sheet Aligmet Place first ONDURA-9 sheet o roof. Alig the ONDURA-9 sheet to the rake edge. Alig the eave edge of the ONDURA-9 sheet to overhag the eave by 1 to 1-3/4 iches. Closure Strip Positio Place closure strips uder the ONDURA-9 sheet with the curved side up to fill the corrugatios. The closure strips must be placed where the ails will be located so that the ails will securely hold the closure strips i place durig the life of the roof. For aesthetic reasos, we recommed staggerig the positio of the corrugatio overlap for each row by startig the secod row with a sheet that has fewer corrugatios. As a geeral guide, a ONDURA-9 sheet with 4 or 5 corrugatios should be used for the first sheet o the secod row. The full-width sheets should be used across the secod row. If istallig more tha 2 rows, the odd umbered rows should start with a full-width sheet ad the eve umbered rows should start with a 4 or 5 corrugatio sheet. If possible, we recommed placig the first row of ONDURA-9 sheets o the roof to cofirm coverage with overlaps before the istallatio of the sheets. Nail Positio Note: We recommed geuie ONDURA ails for istallig ONDURA-9 sheets. Geuie ONDURA ails are made from galvaized steel, are rig shaked, ad have a large EPDM rubber washer to improve sealig aroud the ail. Other types of ails may ot provide sufficiet hold-dow stregth. 1/16 ich diameter head 1/8 ich thick x 5/8 ich O.D. EPDM rubber washer.135 ich diameter rig shak Closure Strips ONDURA closure strips fill the space created by the corrugatios. Veted closure strips are recommeded alog the eaves ad ridge of the roof to eable airflow uder the corrugatios. The vetilatio holes are small eough to prevet birds ad isects from formig ests uder the corrugatios. Solid ONDURA closure strips are available to completely block the opeigs uder the corrugatios. Note: ONDURA closure strips fit the ONDURA-9 sheets. We do ot offer a differet set of closure strips for ONDURA-9 sheets. Each closure strip is 44 iches log. Drive each ONDURA ail oly through the crow of a corrugatio ad perpedicular to the roof surface. Be careful ot to overdrive or uderdrive the ail. The rubber washer o the ail should be sugly i cotact with the sheet. Slight had pressure o a ailed-dow corrugatio should ot separate the sheet from washer cotact. Correct Icorrect Icorrect 4

5 Measure distace alog the sheet corrugatio from eave edge of sheet to outer wall of structure. The lower lie of ails should be istalled high eough o the sheet to be o or iside the wall support. The typical distace from the eave edge of a sheet to the outer wall is 2 to 3 iches. For resistace to wid uplift, the maximum distace from the eave edge of a sheet to the first row of ails is 5 iches. 5 ich max Ridge Cap Note: Istall all sheets o both sides of the roof before istallig the ridge cap. Measure the ridge to determie the required coverage. Each ridge cap is 39-1/2 iches log. If more tha oe ridge cap is eeded, they must be istalled with a 7 ich overlap. Allow for 3 or 4 iches of material at ed of ridge to overhag ridge ed. This material will be used to cover the ed of the ridge. 7 ich overlap Istall ails o the first sheet alog the eave ad rake edges. Tip: For each row of ails, istall the first two ails at opposite sides of the sheet ad attach a strig lie betwee them across the corrugatios as a guide for the positio of the other ails. Mark the positio of the strig o the crow of each corrugatio with a pecil. Repeat for each row of ails. Istall ails at remaiig positios, but do ot faste areas which will be overlapped by other sheets. Place ext ONDURA-9 sheet ito positio o roof. 39-1/2 iches Place the first ridge cap at the ed of the ridge away from the prevailig wid, allowig it to project out 3 to 4 iches from the ridge ed. Isert closure strip above ONDURA-9 sheet ad below ridge cap. The closure strips must be placed where the ails will be located so that the ails will securely hold the closure strips i place durig the life of the roof. The sheets must overlap by at least oe corrugatio alog the directio of the eave. The sheets should overlap by at least 7 iches alog the directio of the rake edge. If istallig over purlis, the overlap must be over a purli so that the ail ca be secured ito the purli. Istall ails o sheet i the same maer as the first sheet. For the last sheet i a row, istall ails i the same patter as previous sheets ad i the fial corrugatio alog the rake edge. Istall ails through the ridge cap ad closure strip at every crow of the uderlyig ONDURA-9 sheets. The row of ails should be 1 ich above the lower edge of the ridge cap. If more tha oe ridge cap is eeded, overlap the ext ridge cap before fasteig through the overlap. Place ext ridge cap with 7 ich overlap. Isert closure strip ad istall ails. Istall fial ridge cap with 7 ich overlap ad 3 to 4 ich overhag. Isert closure strip ad istall ails. At each ed of the ridge, cut the overhag portio of the ridge cap alog the crow with a utility kife. Fold dow resultig flaps for a weather guard. Secure flaps to ridge fascia with roofig ails. Fold dow flaps ad secure to ridge fascia. Cogratulatios! You have completed the istallatio of your ONDURA-9 roof. 5

6 ADDITIONAL TIPS Pullig Nails To pull a ail from a ONDURA-9 sheet, use a claw hammer ad a 1-1/2 ich wood dowel or pipe. This techique miimizes the chace of damagig the sheet. Put the dowel or pipe i the valley ext to the crow where the ail will be pulled. The use the dowel or pipe as a leverage poit for pullig the ail. Walkig o a ONDURA-9 Roof Whe walkig o ailed-dow ONDURA-9 sheets, wear softsoled shoes ad walk o areas that have structural support from sheathig or purlis. Always place feet across corrugatios to distribute your weight ad prevet damage to corrugatios. ONDURA-9 is more pliable i hot weather ad less pliable i cold weather.
