DESIGN / INSTALLATION CONSIDERATIONS
MetalSales’panelsaredesignedtobeinstalledoveropenframingand/ordirectlyoverawoodsubstrate(minimum5/8”)
with30#feltmoisturebarrier(oranIceandWaterShieldwhenrequiredbyLocalBuildingCodes).
Alwayscheckwithlocalbuildingcodespriortoallinstallationsforanyadditionalrequirementsthatmaybespecictoyour
area.
GalvanizedandGalvalumepanelsshouldnotbeincontactwith,orsubjectto,waterrunofffromcopper,leadoruncoated
steel materials.
Condensatewaterfromairconditioningunitstypicallycontainsdissolvedcopper.Thiscondensateshouldbedischarged
throughaplasticpipeextendedbeyondtheedgeoftheroof.
GENERAL
CONDITION OF SUBSTRUCTURE
Theroofshouldbeinspectedforanytrappedmoistureorstructuraldamagesuchasbowingorsaggingraftersandwarpedor
looseroofpurlinsorsoliddecking.Theseareasshouldberepairedpriortoinstallingnewmetalpanels.
Priortoinstallation,makesuretherearenonailsorfastenersprotrudingfromtheroofframingorwoodsubstratewhichcould
damagethepanelsandimpedetheinstallationprocess.
Wheninstalled,paneldistortionmayoccurifnotappliedoverproperlyalignedanduniformsubstructure.
Whetherinstallingoverneworexistingroof,theinstallershouldchecktheroofdeckforsquarenessbeforeinstallingpanels.
Severalmethodscanbeusedtoverifysquarenessofthestructureforproperinstallationofthepanels.
METHOD“A”-Onemethodforcheckingtheroofforsquarenessistomeasurediagonallyacrossoneslopeoftherooffrom
similarpointsattheridgeandeaveandobtainthesamedimension.
METHOD“B”-The3-4-5trianglesystemmayalsobeused.Tousethissystem,measureapointfromthecorneralongthe
edgeoftheroofatamoduleofthree(3).Measureapointfromthesamecorneralonganotheredgeatamoduleoffour(4).
Bymeasuringdiagonallybetweenthetwopointsestablished,thedimensionshouldbeexactlyamoduleofve(5)tohavea
squarecorner.Multipleusesofthissystemmayberequiredtodeterminebuildingsquareness.Iftheendwallcannotbemade
square,theroofsystemcannotbeinstalledasshownintheseinstructions.
