Technical/insTallaTion informaTion
IMPORTANT NOTICEREAD THIS MANUAL COMPLETELY PRIOR TO BEGINNING THE INSTALLATION OF THE LOkSEAM® ROOFING SYSTEM. METL-SPAN DETAILS MUST BE FOLLOWED AS A MINIMUM TO INSURE APPROPRIATE WARRANTIES WILL BE ISSUED.
ALWAYS INSPECT EACH AND EVERY PANEL AND ALL ACCESSORIES BEFORE INSTALLATION. NEVER INSTALL ANY PRODUCT IF ITS QUALITY IS IN QUESTION. NOTIFY METL-SPAN IMMEDIATELY IF ANY PRODUCT IS BELIEVED TO BE OUT OF TOLERANCE, SPECIFICATION OR HAS BEEN DAMAGED DURING SHIPMENT.
IF THERE IS A CONFLICT BETWEEN PROJECT ERECTION DRAWINGS PROVIDED OR APPROVED BY METL-SPAN AND DETAILS IN THIS MANUAL, PROJECT ERECTION DRAWINGS WILL TAkE PRECEDENCE.
Ice Dam DisclaimerMetl-Span designs its standing seam roofs to meet the load requirements dictated by governing codes and project specifications, including applicable snow loads. However, Metl-Span expressly disclaims responsibilty for weathertightness or roof point loading issues or other hazards resulting from ice dam situations. Any time ice and snow can melt on the main body of the roof and refreeze at the eave or in the shadow of an adjacent wall, an ice dam situation may develop. In addition to local climate, ice dam formation is affected by many other factors, including but not limited to, roof insulation R value, roof panel color, interior temperature of building, heater location in building, eave overhangs, parapet walls, shading of building roof areas from adjacent trees, parapets, buildings, etc. These factors are design and maintenance issues and are outside the control of Metl-Span. Metl-Span specifically disclaims any liability for damage due to ice dam formation, although the following issues should be taken into consideration concerning standing seam roofs installed in freezing climates:
• Alwaysusefieldseamedpanels.Thesemachine-foldedseamsaremoredurablewhensubjectedtooccasionalicing.
• Eliminate "cold" eave overhangs and parapet walls from the building design. Roof overhangs outside the heatedenvelope of the building will tend to be colder than the roof areas over the heated envelope. Simple roof designs arepreferred. Parapet walls at the eave allow ice and snow to collect due to shading effects and the lower roof temperaturescaused thereby.
• Make sure the interior of the building is adequately insulated and the heating is properly distributed. Inadequateinsulation in the roof and/or improper heat distribution causes heat flow though the main body of the roof. On days whenthe temperature is below freezing, this heat gain can cause ice and snow to melt and refreeze at the eave where theroof is colder.
• Layoutthebuildingtopreventtheeavesandotherroofareasfrombeingshadedduringthewinter.Thismaymeaneliminating adjacent trees or reconsidering roof geometries.
• Considerusingself-regulatingheatingcablesattheeavestomitigatetheeffectsoficedams.
• Onbuildingdesignsusingattics, over-insulate theattic floor andprovideadequate ventilation in theattic.Thiswillreduce heat transfer through the roof resulting in more consistent roof temperatures between eave and field of roof.
• Increasethedegreeofdiligencewithrespecttounderlaymentmaterialsatroofareaspronetoicing.Thismayincludevalleys, eaves, dormers and roof areas near dormers, parapets and the like where shading may occur.

11. The information in this manual is believed to be correct and accurate. It should not be used for any specific application without being reviewed by a registered professional engineer. All metal roofs should be designed by a registered, professonal engineer for loads specified by the governing code, including the higher pressures encountered at the edge zones of the roof.
12. Avoid restricting the thermal expansion and contraction of the LokSeam® panels. (ie: Do not attach panels to the substructure at both the eave and ridge.)
13. LokSeam® panels are not designed to be work platforms. Avoid any unnecessary foot traffic on LokSeam® panels. If foot traffic is required, protect the roof panels by using some type of roof pad, temporary deck, or walkway.
14. When installing LokSeam® panels over open framing with blanket insulation: (A) install insulation parallel to purlins or joists, or (B) install insulation across purlins or joists and compress it with pinch bars. (¼" thick radiant barrier insulation may be used as an alternative to blanket insulation.)
CAUTIONDiaphragmcapabilitiesandpurlinstabilityarenotprovidedbyMetl-Span’sLokSeam® roof system.
Therefore,otherbracingmayberequiredtoconformtoA.I.S.C.orA.I.S.I.specifications.
WARNINGAswithallstandingseamroofsystems,soundattenuation(example:blanketinsulation)shouldbeinstalledbetweenthepanelsandopenframing,suchaspurlinsorjoists,toprevent“roofrumble”duringwindyconditions.
Applications over solid deck such as rigid insulation over a metal deck or a wood deck may require additional acoustical consideration to ensure that thermal vibration noises are isolated from the building interior. This is especially important if the bottom of the deck is left open to the interior, in cathedral ceiling applications or when the attic space is used as a return air plenum.
A vapor retarder may be necessary to protect roofing components when high humidity is a factor. The need for a vapor retarder, as well as the type, placement and location should be determined by an architect or engineer. The following areexamplesofconditionsthatmayrequireavaporretarder:(A)aprojectwhereoutsidewintertemperaturesbelow40degreesF.areanticipatedandwhereaveragewinterinteriorrelativehumidityof45%orgreaterisexpected.(B)building usages with high humidity interiors such as indoor swimming pools, textile manufacturing operations, food, paperorotherwet-processindustrialplants.(C)Constructionelementsthatmayreleasemoistureaftertheroofisinstalled, such as interior concrete, masonry or plaster work and fuel burning heaters.

GENERAL INFORMATION
1. A single pitch eave strut must be used with the LokSeam® Roof System.
2. Make sure a rake angle or an alternate structural flat surface has been installed on top of the purlins to accept the“RakeSupport”.
3. The walls do not have to be erected before the roof is installed. However, for the purpose of this manual, we have assumed that the wall panels have been installed.
4. Thesubstructure(eavetoridge)mustbeonplanetoleranceof¼"in20'and⅜"in40'.
5. It is critical that the purlins or bar joists at the ridge and endlaps be located exactly as detailed and that they are straight from rafter to rafter. Any mislocation or bowing of these members can cause the fasteners at the ridge or endlaps to foul as the panels expand and contract.
6. PeakPurlinSpacing-FloatingRidge:18"(9"fromcenterlineofridgetowebofpurlin).-FixedRidge:10"(5"fromcenterlineofridgetowebofpurlin).
7. Metl-Span can furnish LokSeam®roofpanelsin18",16"and12"widths.However,forthepurposeofthismanual,wehaveassumedthattheroofpanelswillbe18"wide.

HANDLING/ PANEL STORAGE
Standing on one side of the panel, lift it by the seam. If the panel is over 10' long, lift it withtwo or more people on one side of the panel to prevent buckling.
Donotpickpanelsupbytheends.
Store bundled sheets off the ground sufficiently high to allow air circulation beneath bundle and to prevent rising water from entering bundle. Slightly elevate one end of bundle. Prevent rain from entering bundle by covering with tarpaulin, making provision for air circulation between draped edges of tarpaulin and the ground.
PROLONGED STORAGE OF SHEETS IN A BUNDLE IS NOT RECOMMENDED. If conditions do not permit immediate erection, extra care should be taken to protect sheets from white rust or water marks.
Check to see that moisture has not formedinside the bundles during shipment. If moisture is present, panels should be uncrated and wiped dry, then restacked and loosely covered so that air can circulate between the panels.

LokSeam®
DETAILS
Metl-Span recommends that only one-piece .080 Aluminum (Min.) roof curbs be used with the LokSeam® roof system. The roof curb will be installed under the roof panels on the upslope end and over the panels at the downslope end. To accomplish this, the roof panels must be endlapped at the upslope and downslope end of the curb. This allows both ends of the curb to shed water and places the heavier gauge metal of the curb under the roof panels for better resistance to foot traffic. The exception is at the downslope end where the curb is on top of the roof panels. Since there are endlaps at this area, back-up plates provide support.
Outsidecapcells(forbottom)areusedtosealthe panel to the roof curb. If the curb must be located in a precise location, order the cap cells loose for field installation.
For the purpose of these instructions, a curb with a factory attached cap cell is illustrated. Panels are assumed to be blank and installed right to left.
ROOF CURB INSTALLATION INSTRUCTIONS
CAUTIONIt is the user’s responsibility to ensure that openingscut into the roof for installation of roof curbs comply with State, Federal and OSHA regulations and laws, including, but not limited to, guarding roof openings with plywood, fixed standard railings, or other acceptable safety controls that prevent fall-through.

DETAILS
Full length panels may be installed up to the curb location. All panel runs affected by a roof curb must have field endlaps at the upslope and downslope end of the curb. Provision must be made for this condition by ordering two panels12" longer than thepanels immediatelyadjacent to the curb. The panels do not need to be ordered with pre-punched holes. Install all bottom panels, engaging backup plates and apply triple bead tape sealer to each panel as it is being installed. It is critical that the tape sealer be installed across the full panel width. Failure to follow this procedure will cause the curb to leak during rains coupled with high winds.
The first downslope panel immediately adjacent to the last full length panel will require field notchingof the female leg foradistanceof6".Notch the panel just above the lock in the female leg. The remaining portion of the female leg will needtobecrimpedwith“duckbill”visegrips.
The last downslope panel immediately adjacent to the first full length panel after the curb will require field notching of the male leg for a distance of 6". Notch the panel by removingthe male “lock” leg only. Apply two beads ofurethane sealant vertically to the downslope end of the notch.
