Notes to the Designer/User
The details contained in this packet are intended to be a design aid and do not depict all situations . Modifications are the
responsibility of the designer/user and should take into account climate conditions such as wind and snow, governing code requirements, and the actual usage and maintenance of the structure . AEP Span makes no representations or warranties regarding modifications from the recommendations contained in this installation guide, situations not depicted in this guide or
the any services/work performed by the designer/ user of this guide .	As with all architectural and design services, the user of this installation guide must use his/her professional judgement and expertise when specifying and installing building products .

Where possible, roof and flashings should be lapped away from prevailing winds . Certain flashings should be supported if it is likely that a ladder will be used against them or if foot traffic is anticipated . Check with AEP Span any time you intend to specify a prefinished flashing in
a gauge different than the panels . Our standard gauge for all of the products in this booklet is 24 gauge and the standard finish is Kynar 500™/ Hylar 5000™ . It is good practice to specify that all flashings be of the same material (gauge, color, finish) as the roof panels to ensure long- term durability . Field-painted flashings rarely equal the durability and color fastness of factory
baked-on paint systems . Where possible we have minimized the use of exposed fasteners and have hemmed the edges of flashings to strengthen them and to minimize the exposure of cut edges .

Substrates - The Span-Lok™ and SpanSeam™ roofing panels can be used over spaced support members or over solid substrates .

Slope Requirements - The panels in this booklet should be used on slopes of 1/4”:12 or greater .

Condensation,  Insulation,  &  Ventilation  - It is the designer’s responsibility to determine the need and composition of condensation control materials including insulation and vapor retarders, as well as ventilation requirements .
Metal roofing is susceptible to condensation and its control should be carefully considered . Applications over rigid insulation may require solid blocking/framing for installation of perimeter flashings and fasteners (ref . drag load tables) .

Underlayments - Prior to panel installation a minimum of 30 lb . felt (or two layers
of 15 lb . felt) should be installed per the felt manufacturer’s recommendations . The
underlayment should be lapped with all flashings in a shingle-like manner . When a premium underlayment is required, a self-adhering, cold- applied rubberized asphalt membrane should be specified .

“Pinning” Requirements - The panels must be “pinned” at one end only to resist the “drag” load caused by the weight of the panel, live loads, and snow loads . The intensity of the drag load is a function of slope, the loads involved, and the length of the panels . Appendix “A” gives the drag loads for various slopes and
loading conditions, and Appendix “B” shows the fasteners required to resist the drag load .

Expansion & Contraction - Both the panels and the flashings must allow for expansion and contraction of the materials, especially where long lengths are used . The overlap between the hidden cleat and the turned-under end of the panel at the eave may need to be increased to accommodate thermal movement where long panels (i .e . 30ft .+) are used .

Valleys - Valley dimensions must be the proper width to account for slope, snow, ice, and rain conditions . Valleys should receive a premium

underlayment since they are susceptible to water buildup . If valleys are not kept free of debris
and water does back up, intrusion may occur under the panels . An underlayment such as a self-adhering cold-applied rubberized asphalt membrane should be put down first, extending 3 ft . up from the center of the valley on each side . The 30 lb . felt should then overlap this underlayment .

Snow Design - Span-Lok™ and SpanSeam™ are suited for heavy snow loads . If possible, valleys, gutters, roof elevation changes and penetrations should be minimized or eliminated in snow areas . Roof penetrations should be located as close to the ridge or peak of the roof as possible to minimize accumulations of ice and snow
and the effects of thermal movement of the roof panels . Premium membrane underlayments should be used . Valleys in snow areas require special consideration due to the accumulation of snow and ice from tributary roof areas .

Oil Canning - Flat metal surfaces will display waviness commonly referred to as ‘oil canning’ . This is caused by steel mill tolerances, variations in the substrate and roofing underlayments .
Oil canning is a characteristic, not a defect, of panels manufactured from light-gauge metal . Panels are factory “corrective-levelled” to minimize oil canning . Oil canning is not a cause for panel rejection . Additional information is available upon request .

References - The Sheet Metal and Air Conditioning Contractors’ National Association Inc . (SMACNA) manual is an excellent reference for sheet metal contractors . Its guidelines for underlayments, gutter and downspout size requirements, and expansion/contraction of metals and flashing joints should be followed .

Technical Assistance - Call your AEP Span Sales Representative for additional information on any of these subjects .

Definitions -
Sealant = Gunnable-grade non skinning/non curing butyl rubber
Mastic = Butyl mastic tape

Hem: A 180º bend that is closed (or as closed as the formability of the metal will allow) to provide a uniform, attractive edge .

Hook: (also called an “open hem”) A 180º bend on a piece of sheet metal that is left open to allow insertion of another piece of sheet metal . For example, the hook shown is used to hold the trim piece to a cleat below the trim .

NOTE: References to ‘Span-Lok’ in this installation guide also apply to ‘Span-Lok hp’ unless otherwise noted .

Onsite Services
Curved Span-Lok
16” wide x 2” tall Span-Lok panels (not Span-Lok HP or SpanSeam) are available Factory or Jobsite curved . Page 33 provides Rake and Rake Wall details that are unique to the curved Span-Lok installation .

Inquire with your AEP Span sales representative for additional details . There is also an AEP Span Curved Span-Lok Customer Guidelines document available that explains the requirements and expectations in greater detail .

Procedures
To facilitate the handling of Span-Lok™ panels, panel packages can be lifted and placed on the roof if located at a rigid frame and with blocking placed to prevent the purlins from rolling over .
When lifting packaged sheets, make certain that they are adequately supported, panels less than 20’ in length can normally be lifted with a forklift .

When lifting panels in excess of 20’, it is recom- mended that a spreader bar and slings be used . As a rule when lifting, no more than 1/3 of the total length of the panel should be left unsupport- ed, and no more than 8’ should be cantilevered beyond spreader bars .

Sheeting Direction and Panel Sequence

Procedure
The sheeting sequence for the Span-Lok™ and SpanSeam™ is as indicated above . Please note the placement of the panels by the circled numbers . The uphill panel at an endlap will be swedged on the lower end for nesting purposes . Endlaps
of adjacent panels must be staggered at least one purlin space to prevent material build-up .

Note: Gable buildings without panel endlaps can be sheeted simultaneously from either end of the building . However, if the building has panel end- laps, the roof must be sheeted left to right looking up the slope .

Notes:
#12-14 x 1” S .D . values are based on a 16 gauge minimum substrate .
1/4 - 14 x 7/8” S .D . values are based on a 22 gauge minimum substrate .
#14 x 1” Type A Milled Point values are based on a minimum 1/2” C-D plywood or 1” nominal Hem-Fir .
Fasteners must be located a minimum of 1” from each other and from the end of the panel .

Example:
Span-Lok™ and SpanSeam™ attaching to 1/2” plywood 4:12 slope
30 psf snow load
40 foot maximum sheet length
a .	From Appendix A, find the Drag Load per Lineal Foot of panels (4:12, 30 psf snow load = 14 .23 plf .)
b .	Multiply the load by the length of the panel to obtain the total drag load on the sheet . (14 .23 x 40 = 569 .2 lbs . drag force per panel .)
c .	Find the drag load in Appendix B . The nearest value is 640 lbs . The number of fasteners required per panel is five (5) .
