Failure to do so may result in substantial fines in theevent of an OSHA inspection. Safe installation practicesmay be further defined and made mandatory by state orlocal ordinances.

Maintaining good housekeeping on the jobsite isrecognized as being important to both OSHA complianceand to successful job completion.

The Occupational Safety and Health Act (OSHA) haspromulgated many regulations applicable to theinstallation of this or any other roof system. Theseregulations, identified as Part 1926, Safety and HealthRegulations for Construction, are available from anygovernment bookstore. The objective of the OSHAstandards is to protect the worker from injury or illness.These OSHA regulations should be recognized as job siterequirements and be fully complied with.

If the erector cannot safely assemble the roof system inaccordance with these instructions, it is the responsibilityof the erector to stop the work and contact Bigbee SteelBuildings, Inc. to determine alternate assemblyprocedures.

The erector of the roof system is responsible for the safeexecution of this installation guide. These instructions areintended to describe the sequence and proper placementof parts. They are not intended to prescribecomprehensive safety procedures.

2.2 OSHA

2.1 Erector's Responsibilty2.0 SAFE ROOF INSTALLATION

2.3 Walking & Working on Roof PanelsA. PLACING PANELS ON THE STRUCTUREDo not place bundles of panels on the roof structurewithout first verifying the structure will safely support theconcentrated weight of the panels and the weight of theinstallation crew. Some roof structures may not bedesigned to support the weight of a full panel bundlewithout additional structure support.

B. WALKING ON ROOF PANELSDo not use a roof panel as a working platform. Anunsecured panel could collapse under the weight of aperson standing between purlins or at the panel end.

Do not walk on the last installed panel run, as theunsecured edge could collapse under a person's weight.When installing endlap connections, etc., stand wherethe roof structural will support your weight.

An approved and safe walking platform should beused in high traffic areas to prevent the roof panelfrom being deformed, scratched, or scuffed.

2.0 SAFE ROOF INSTALLATION2.3 Walking & Working on Roof Panels (Continued)

2.4. Handling Roof Materials in Strong Winds

C. SAFETY EQUIPMENTThe use of safety equipment for the roof panel installationis recommended at all times during the installationprocess. However, when using lanyards, ensure that theclasp, belt hooks and wire cables are covered in such amanner that they will not scratch the panel surface ifaccidentally dragged along the panel.

D. CREW SIZEThe length of the individual roof panels should beconsidered when determining the crew size. It isrecommended that under normal conditions, there beone person for every ten feet of panel length, plus one.

E. PANEL OVERHANGDo not stand on the end of unsupported (cantilevered)panels at the eave or ridge. Standing on the cantileverportion may result in panel collapse.

F. POINT LOADSWhen properly supported by the structurals, panels aredesigned to support uniform loads, which are evenlydistributed over the panel surfaces. Point loads thatoccur in small or concentrated areas, such as heavyequipment, ladders or platform feet, may cause paneldeformation or even panel collapse.

G. SLICK SURFACESPanel surfaces and structural steel surfaces are hard,smooth, and nonabsorbent, which causes these surfacesto be very slick when wet or covered with snow or ice.Even blowing sand or heavy dust can make thesesurfaces difficult to walk on without slipping.

Unpainted panel surfaces are often coated with oil toaccommodate the panel-fabrication process. Althoughdesigned to wash away or evaporate during normalweather, the oil on new panels can be extremely slick,especially during periods of light rain or dew.

Caution must be exercised to prevent slipping and fallingonto the roof surface or even sliding off the roof. Non-slipfootwear is a necessity and non-slip working platformsare recommended.

H. ELECTRICAL CONDUCTANCEMetal panels are excellent electrical conductors. Acommon cause of injury is the contact of metal panelswith power lines during handling and installation. Thelocation of all power lines must be noted and, if possible,flagged. The installation process must be routed to avoidaccidental contact with all power lines and high voltageservices and equipment. All tools and power cords mustbe properly insulated and grounded and the use ofapproved ground fault circuit breakers is recommended.

I. FALSE SECURITY OF INSULATIONBlanket and board insulation blocks the installer's view ofthe ground below the roof. Serious injury can occur whenthe installer gets a false sense of security because hecannot see the ground and steps through the insulation.

J. SHARP EDGESSome edges of panels and flashing are razor sharp andcan cause severe cuts if proper protective hand gear isnot worn. Be careful not to injure others while movingpanels and flashing.

Do not attempt to move panels in strong winds. Windpressure can easily cause a man to lose balance and fall.Strong wind uplift on a panel can lift the weight of the mancarrying the panel.

Loose, wind borne panels are very dangerous and cancause severe injury and damage.

Secure stacks of panels with banding or tie-downs, sowind will not blow the panels off the roof. Clampindividual unsecured panels to the roof structurals.Clamp or block panel bundles and accessory crates toprevent them from sliding down the roof slope.

To assure that the accumulation of structure length errorand rake straightness error does not exceed the roofsystem's tolerance, the structure length should bemeasured from rake line to rake line at each eave, at theridge and at each point where there is a significant erroror change in rake straightness (this usually occurs at anend rafter splice).

B. MEASURINGStructure length and width may be measured with a steelmeasuring tape from the face of the eave or rake memberto the face of the opposite eave or rake member. Themeasuring tape must be parallel to the relative eave orrake line and must be stretched taut.

Eave and rake straightness may be determined bymeasuring deviations from a string line, which is stretchedtaut along the eave or rake line.

C. AESTHETIC ACCEPTANCEAlthough these structure alignment tolerances will allowfor reasonable roof component fit-up and ease ofinstallation, the extremes of these tolerances may beaesthetically objectionable and should be confirmed withthe customer before starting the roof installation.

D. CORRECTIONSAny structure alignment error, which exceeds the abovestated tolerances, must be corrected before roofinstallation can begin. If it is decided that the structurealignment errors cannot be corrected, alternate roofdetails may have to be developed. The alternate detailsmay require additional materials, modified parts (withadditional cost, fabrication and delivery time) andadditional installation time. Bigbee Steel Buildings, Inc.CANNOT assure the performance of such alternatedetails.

Prior to installation, roof structurals should be checkedfor overall dimensions and evenness of plane. The roofstructurals should also be checked to verify the roofsystem could be installed without interference. Also, roofstructurals nearest the panel endlaps, ridge or high eaveshould be checked for correct location to properlyaccommodate the roof components.

A. TOLERANCESTo assure the roof system's correct fit-up and designedweather tightness, the structure must be aligned withinthe following tolerances:

Out of Square -- The roof system can only accommodate1/4" of sawtooth of the roof panel ends at the eave, ridgeand panel splices. This means the allowable out ofsquare of the rake line relative to the eave line and ridgeline is 1/4" for each 40' of rake run.

Structure Width and Eave Straightness -- The roofsystem is designed to accommodate ±2" of overallstructure width error, or ±1" of eave straightness error ateach eave.

To assure that the accumulation of the structure widtherror and eave straightness error does not exceed theroof system's tolerance, the structure width should bemeasured from eave line to eave line at each rake, at thefirst frame line from each rake and at each point wherethere is a significant error or change in eave straightness(this usually occurs at a frame line or at a wind column).

Structure Length and Rake Straightness -- The roofsystem is designed to accommodate ±2" of overallstructure length error, or ±1" of rake straightness error ateach rake.

3.3 Alignment

3.0 CHECKING THE STRUCTURE3.1 Completed and Braced

3.2 Lateral Stability

Before placing materials and workers on the roofstructure to start roof installation, it must be confirmedthat the structure is designed to accommodate thematerial and erection loads as well as the appropriate liveloads and wind uplift loads. It also must be determinedthat the structure is complete

and structurally sound with all structural connections andbracing in place and secure.

The roof panels to the roof structurals provides onlylimited lateral stability and diaphragm bracing to the roofstructurals. Before placing materials on the roof andstarting the roof installation,

confirm that the necessary roof bracing and sag angles,strapping or bridging for purlin stability is in place andsecured.

A spreader bar will be required for the longer panel cratesto assure correct sling spacing and uniform lifting. Thespreader bar must be large enough to handle themaximum panel bundle weight and length.

A forklift is handy for unloading and placing shorter paneland accessory crates.

Hoisting equipment is necessary to unload and positionthe panels and accessory crates for site storage andinstallation. The equipment must have sufficient capacityand reach to place the material where it is required forefficient installation.

Slings will be required to minimize panel damage. Therecommended slings are nylon straps of 6" minimumwidth and of sufficient length to accommodate the panelbundle girth.

It is imperative that any shortages or damage of thedelivered materials be noted at once and clearly markedon the bill of lading before signature of acceptance.Notify Bigbee Steel Buildings, Inc. immediately of anyconflicts. Bigbee Steel Buildings, Inc. will not beresponsible for shortages or damages unless they arenoted on the bill of lading.

In the case of packaged components (such as clips,fasteners and sealants, etc.), the quantities are markedon their container and should be checked against the billof materials. Bigbee Steel Buildings, Inc. must benotified of any shortages or concealed damage within15 days of delivery.

Your material is carefully inspected and crated beforeleaving the plant and accepted by the transportationcompany as being complete and in satisfactory condition.It is the carrier's responsibility to deliver the shipmentintact. It is the consignee's responsibility to inspect theshipment for damages and shortages when it is delivered.

Conducting a material inventory at the time of delivery isessential. By conducting the materials inventory, theerector is able to identify any material shortage ordamage and avoid stopping installation later because ofsuch shortage or damage.

4.2 Equipment For Unloading and Lifting

4.1 Material Inventory4.0 RECEIVING & HANDLING ROOF MATERIALS

4.3 Lifting Roof Panel BundlesUnder normal conditions, panel crates less than 35' longcan be lifted with two slings spaced at third points. Panelcrates longer than 35' can be lifted with three slingslocated at quarter points using a spreader bar to achievecorrect sling spacing for uniform lift.

Slings should be located under the cross boards. Loadsshould always be checked for secure hook-up, proper

balance, and lift clearance. Tag lines should be used ifnecessary to control the load during lifting, especially ifoperating in the wind.

Panel crates less than 25' long may be lifted with a forkliftonly if the forks are spread at least 5' apart and blockingis used to prevent panel damage by the forks.

4.0 RECEIVING & HANDLING ROOF MATERIALS4.4 Field Storage of Roof Materials

Upon acceptance of the shipment, the customer or hisrepresentative is responsible for proper handling storageand security of the roof materials. Bigbee Steel Buildings,Inc. is not liable for damage or loss of materials at the jobsite.

The panel bundles should be stored on the job site inaccordance with the following recommendations:

A. Store panels in a protected area, out of standingwater and drifting snow, etc.

B. Elevate panels with blocking to allow air circulationunder the bundle.

C. Slope panels for drainage of moisture from thepanels.

D. As necessary, cover panels with waterproof tarp,allowing for air circulation (do not wrap tarp under panelcrate or restrict air movement).

E. Inspect panels daily for moisture accumulation.

F. If panel bundles contain moisture, the panels shouldbe dried and re-stacked. Use care in re-stacking to avoiddamage to panels.

G. Opened or re-stacked panel bundles should besecured to prevent wind damage.

When moving panel bundles, extreme caution should betaken to prevent damage to the panel edges. Uncratedpanels should be supported at each end and at 8' spaces.

All bundles or loose panels on the roof should be bandedto the roof structurals at the end of each workday. Onsteep roofs, provisions should be taken to prevent panelsand panel crates from sliding off the roof. Be sure to setpanel bundles on the roof in the proper direction for theinstallation sequence.

Trim and accessories should be stored in a secure areaand protected from damage, weather, and theft.Fasteners, sealants, closures, etc. should be stored outof the weather and protected from contamination.

Panel Bundle

Blocking

Stack blocking so bundleis sloped for drainage

The jaws of the vice grips must be padded to preventdamage to the panel surface. The clamps should beuniformly spaced, no more than 10' apart and the handlines must be pulled in unison so that uneven lifting doesnot buckle the panel. Be sure the clamps are tight on thepanel and the line is secure to prevent dropping thepanel, which can result in personal injury and propertydamage.

To lift individual panels, lift one side of the panel by theseam letting it hang naturally to prevent buckling. Pick-uppoints should NOT be more than 10' apart. Do notpick-up panels by the ends only, or in a flat position.

If the individual panels are to be lifted to the roof by handline, the common method is to use the vice grip "C"clamps. Position the clamps on the flat of the panel, asclose as possible to one edge so the panel is lifted in avertical position.

5.0 ROOF INSTALLATION BASICS5.1 Proper Tools

Before starting paneling, be sure that the properequipment and tools are on hand. The tools must be ingood operating condition and operators should adhere tosafety precautions at all times.

Improperly operating tools, too few tools, inadequatepower source, or other equipment deficiencies slow downthe installation process. The cost of inefficient working isusually greater than the cost of providing goodequipment.

This list should not be interpreted as a limitation to yourinventory of installation equipment.

The following tools and equipment should be consideredfor efficient installation of the Bigbee Steel Buildings, Inc.panels. Actual tools and equipment required may varydue to variations in building type and construction.

5.2 Equipment List

Screw Guns -- Designed for use with self-drilling screwsSocket Extensions -- 6" extension for screw gun HexSocket Heads -- 5/16" and 3/8", magneticDrill Motor -- 1/4" capacityDrill Bits -- AssortmentSheet Metal Cutter -- or power shears or nibbler"C" Clamps -- vise grip type with swivel padsPop Rivet Tool -- 1/8" capacitySheet Metal Shears -- left and right cutHack Saw -- with metal cutting blade

Steel Measuring Tape -- 12', 50', 100'Nylon String LinesChalk Line (NO red chalk)BroomsMarking Pen (NO lead pencils)Caulk Guns -- for 1/10 gallon sealant tubesPower Source and Extension Cords -- capable ofhandling the total equipment requirements, without powerdrop due to extension cord length.

B. CONTAMINATIONTo assure proper adhesion and sealing, the sealant musthave complete contact with adjoining surfaces andachieve 30% compression. Contaminants such as water,oil, dirt and dust prevent such contact. The panel andflashing surfaces must be dry and thoroughly cleaned ofall contaminants. Before applying tape sealant, thesealant should be checked for contaminants. If thesealant surfaces are contaminated, it must not be used.

During cool weather, condensation or light mist canaccumulate on the panel and flashing surface and not beeasily noticed. It is recommended that sealants alwaysbe kept under protective cover and that the panel andflashing surfaces be wiped dry immediately beforeinstallation.

Tape sealant is provided with a protective paper toreduce contamination. Incomplete removal of theprotective paper will prevent the sealant's adhesion to thepanel or flashing surfaces. Always check that theprotective paper is completely removed. Do not removethe protective paper until immediately before the panel orflashing is installed over the sealant.

A. TEMPERATURE EFFECTSTemperature extremes must be considered duringinstallation of the roof due to the sensitivity of sealants.The recommended installation temperature range is 20° Fto 120° F. At colder temperatures, the sealant stiffensresulting in loss of adhesion and compressibility. Athotter temperatures, the sealant becomes too soft forpractical handling. On cold but sunny days, the panel'ssurface may become warm enough to accept theapplication of a heated sealant even though the airtemperature is below 20° F.

When overnight temperatures fall below freezing, thesealant should be stored in a heated room so it will bewarm enough to use the following day. On hot days, thesealant cartons should be stored off the roof in a cool andshaded area. While on the roof, sealant rolls should bekept shaded until actual use.

In very cold weather, it is recommended that thefasteners be tightened slowly and only tight enough thatthe sealant is in full contact with the panel or flashing.Then on the next sunny day, complete the tighteningprocess after the sun warms the panel and flashingsurfaces.

5.3 Sealants

D. INSIDE CORNERSAn inside radius, such as where the panel flat meets a rib,is usually the most critical area to seal. A commonmistake for the installer, is to bridge the sealant acrossthe inside radius.

When the lapping panel or flashing is pushed into place,the bridged sealant is stretched and thinned. The sealantmay then be too thin to adequately seal this critical area.When tape sealant is applied at an inside radius, it isrecommended that the sealant be folded back on itself,then push the sealant fold into the radius. Do not tear butcut the tape sealant to length with a box knife or equal.

C. COMPRESSIONTo assure proper adhesion and seal, the tape sealantmust be compressed between the panel and flashingsurfaces with firm and uniform pressure. In most cases,the required pressure is applied by the clamping action ofscrews pulling the adjoining surfaces together. However,the tape sealant's resistance to pressure becomesgreater in cold weather.

During cold weather, the fasteners must be tightenedslowly to allow the sealant time to compress. If thefasteners are tightened too fast, the fastener may stripout before the sealant compresses adequately, or thepanel or flash may deform in the immediate area of thefastener, leaving the rest of the sealant insufficientlycompressed.

5.4 FastenersA. SCREW GUNUse torque control and variable speed screw guns fordriving self-drilling screws. 2000-2500 RPM screw gunspeeds are necessary to attain efficient drilling speeds.High tool amperage (4 to 7 AMP) is required to achievethe proper torque for proper seating and to secure thefastener.

B. SOCKETSUse good quality magnetic sockets. Good fitting socketsreduce wobble and stripping of the screw heads,especially the alloy and capped heads. They alsominimize objectionable paint chipping and scuffing oncolored screws and minimize damage to the protectivecoating on unpainted screws.

Magnetic sockets collect drill shavings, which will build upand eventually prevent the socket from seating properlyon the screw heads. One method of removing the drillshavings is to roll up a ball of tape sealant and push thesocket into the sealant.

When the socket is removed from the sealant, most of thedrill shavings will remain embedded in the sealantthereby cleaning the socket. This process should berepeated as often as needed to keep the socket clear ofdrill shavings.

C. SOCKET EXTENSIONA 4" or 6" socket extension is recommended for installingthe panel clip screws. With the extension the screw canbe driven straight down without tilting the screw gun toclear the panel. Since socket extensions are slow towear out, it is usually more cost effective to purchasesocket extensions and good quality sockets rather thanpurchase sockets with built-in extensions.

D. INSTALLATIONBefore starting the screw, the materials to be joined mustbe pressed together with foot or hand pressure. Thepressure must be maintained until the screw has drilledthrough all the materials and the threads have engaged.

5.0 ROOF INSTALLATION BASICS5.4 Fasteners (Continued)

D. INSTALLATION (continued)Most self-drilling screws require 20 pounds of pressure tomaintain the drilling action and to start the thread cuttingaction. Also, applying such pressure before starting thescrew gun will usually prevent tip walking or wandering.

If too little pressure is applied, the drill point may not cutinto the metal and the point will heat up and become dull.If the pressure is too heavy, the bottom material may bedeflected away, causing a standoff condition, or the drilltip may be broken or splits. Screws must be heldperpendicular to the panel or flashing surface duringstarting and driving.

For proper seating of the fastener-sealing washer, thepanel or flashing surface must be clean and drill shavingsmust be removed from under washers before seating.The fastener must be driven perpendicular to the panelsurface so that the washer can seat level without warpingor cupping.

Do not over drive screws. Over driving can strip thethreads and/or damage the sealing washer. Use screwgun with torque control set to function properly for thecombination of fastener size, hole size and materialthickness.

The fastener should be driven tight enough to uniformlycompress the washer but not so tight that the washersplits or rolls out from under it's metal dome. Therecommended procedure is to tighten the fastener untilthe sealing washer just starts to visually bulge from underthe metal dome.

As a good installation practice, all installers should carryapproved oversized screws. Upon stripping or breaking ascrew, the screw must be immediately removed andreplaced with the appropriate oversized screw. Do notdefer the screw replacement to be remembered and fixedlater, or to be found by the clean-up crew. The majorityof such screws will be overlooked until the customercomplains of leakage.

When field cutting complex shapes, it is usually easier tocut out a 1" wide strip using both left and right handshears. The 1" cutout provides clearance to smoothly cutthe flats and the clearance to work the shears aroundtight corners.

When making repetitive cuts (such as cutting panels at ahip condition) it is recommended that a template be madefrom a piece of drop-off panel or flash to provide fast andaccurate marking of the field cut. When using panelmaterial for the template, cut off the top portion of thepanel ribs so that the template is easily laid onto the panelbeing marked.

C. MARKING PANELSAvoid marking the panels for cutting, etc., in a mannerthat will leave visible markings stains, etc., on the finishedsurface. Use chalk or felt tip ink markers. Do not usegraphite (lead) pencils on unpainted panel surfaces, thegraphite can cause rusting of the surface.

A. ABRASIVE SAW PROBLEMSAbrasive saws (circular saws with friction disks) are notrecommended for cutting panels or flashing. Abrasivesaws create high heat that may burn away the protectivecoating from the panel edge, causing the edge to rust.

Also, abrasive saw dust contains fine, hot steel particles,which accumulate on panel and flashing surfaces wherethey rust and can cause staining and rusting of thosesurfaces.

Rust caused by abrasive saw damage or abrasive dustparticles can be excluded from warranty claims.

B. SHEARING METHODSIt is recommended that panels and flashing be cut withshears to provide a clean, undamaged cut. On shear cutedges, the protective coating extends to the edge of thecut and is often wiped over the edge to further protect thebase metal. Whenever possible, fit the material so thatthe factory cut edge is exposed and the field cut edge iscovered.

5.5 Field Cutting Panels and Flashing

Caution: Failure to maintain panel coverage widthwithin the specified tolerance can cause faulty panelseams which can result in a reduction in roofperformance.

The panels must be held to the width dimension of thepanel as designated on the erection drawings within a1/8" width tolerance per panel. The accumulatedcoverage (start panel to finish panel) tolerance isdetermined by the ability to keep the panels parallel andto correctly fit and assemble the finish rake condition.

If the roof has conditions such as fixed locationpenetrations, parapets, fire walls, etc., the accumulatedpanel coverage may require tighter tolerances for properfit-up and weather tightness of the roof system.

Although the Bigbee Steel Buildings, Inc. roof system isdesigned so it can be installed in either direction (left toright or right to left), panel side laps should always beorientated away from the prevailing wind direction ifpossible and items such as steps in roof elevation,firewalls, parapets, roof penetration, etc. should also beconsidered. Check the erection drawings to determine ifa specific sheeting direction is required.

The recommended installation sequence is to completeeach panel run from eave to ridge before starting the nextpanel run. This sequence will help ensure straight runsand allow the insulation to be installed immediately aheadof each panel run.

During installation considerations must be made formaintaining panel modularity. By maintaining panelmodularity, the panel side lap can be properly assembled,the proper coverage can be obtained, etc.

6.2 Layout & Checking for CoverageRecommended for all roofs, but a must for large orcomplex roofs, is to make a layout of the actual structure(field measured as described in section 3.3) so that theroof panel start and stop dimensions can be laid out toaccommodate any structural misalignments.

When the optimal start and finish dimensions aredetermined, a string line should be set to precisely locatethe leading edge of the start panel. After the start panelis secured and engaged with the next panel, the startpanel seam will be the reference line for checkingaccumulated panel coverage.

Panel coverage is always checked at the eave, ridge, andend splices so that non-parallel seam (or dogleg)conditions can be detected and corrected before theybecome objectionable. The coverage check should bedone with a measuring tape held taut and measured tothe same side of the seam and always parallel to theeave to prevent any measuring error.

Every four to six panel runs should be checked for panelmodularity. This will assure that the panels aremaintaining a straight line and proper coverage is beingmaintained. If the panels are off module, they should becorrected by equal adjustments of the next four to sixpanel runs.

Although the above stated coverage tolerance will providefor reasonable ease of installation and water tightness,such visible conditions as non-parallel panel seams,dogleg of the panel seam at the end splices, non-parallelfinish panel width, and mismatch of panel seams acrossthe ridge, may be objectionable and should be confirmedwith the customer before continuing roof installation.

6.3 Appearance Considerations *

* Oil-Canning is a natural occurrence in metalpanels that does not affect the finish orstructural integrity of the panel and is thereforeNOT a cause for rejection.

7.0 INSPECTION OF ROOF ASSEMBLY DURING INSTALLATION7.1 Importance of Inspection

During the panel installation, all areas of the roof systemassembly must be frequently inspected to ensure thecorrect assembly in accordance with the erectiondrawings and this installation guide.

Failure to assemble the roof system correctly will result inperformance problems that may require costly correctivework, panel replacement and performance and damageclaims etc. Also, incorrect installation may void theperformance and material warranties.

F. ENDLAP SEALCheck that the roof panel endlaps are correctlyassembled and that the lapping panels are tightly nestedwithout visible gaps.

Check that the sealant is in the correct position and is incomplete contact with the lapped panels without anyvoids or gaps, especially at the radius between the panelflat and the vertical legs of the panel. Confirm that thepanels are clean and dry during installation and that thesealant is not wet or otherwise contaminated.

Check that the fasteners penetrate through the center ofthe sealant and into the purlin flange. Check that thefasteners are not loose or stripped.

Check that the endlap assembly is not bowed downcausing water ponding and debris accumulations.

G. RIDGE SEALCheck that the ridge closure assembly is correctlyassembled.

Check that the sealant is in the correct position and is incomplete contact with the closure or panel without anyvoids or gaps. Confirm that the closures and roof panelsare clean and dry during installation and the sealant is notwet or contaminated.

Check that the closure fasteners penetrate through thecenter of the sealant and into the purlin flange. Checkthat the fasteners are not loose or stripped.

A. ERECTION DRAWINGSCheck that the erection drawings are available at the jobsite and have been reviewed for difference with the actualjob conditions and differences with this installation guide.Also, confirm that the drawings are the latest issue withthe latest revisions and additions.

B. PANEL LAYOUTSCheck that the start and finish dimensions have beencorrectly determined based on the erection drawings andthe actual structural conditions.

C. BEFORE INSTALLING PANELSCheck that the structural misalingments were corrected inaccordance with Section 3.0 of this installation guide.

Check that the correct flashings are in place beforeinstalling the panels.

D. PANEL LENGTHCheck that the installed roof panels have the correctoverhang at the eave and endlaps and have the correcthold back at the ridge or high eave, in accordance withthe erection drawing.

E. EAVE SEALCheck that the eave sealant is in the correct position ontop of the eave trim and that the closure is correctlyplaced. Check that the eave fasteners penetrate thecenter of the eave sealant and into the eave strut.Check that the fasteners are not loose or stripped.

Check that the eave sealant is in complete contact withthe roof panel and eave trim without any voids or gaps.Confirm that the roof panel and eave trim are clean anddry during installation and that the sealant is not wet orotherwise contaminated.

7.2 Inspection List

performance problems and may void the material andperformance warranties

Check that the panel and flashing surfaces are not beingsubjected to abusive conditions such as: carelesshandling of panels and flashing, excessive roof traffic,abrasive or contaminated footwear, rough handling ofmaterials, tools and equipment, or contact with abrasivematerials or residue.

Check that the panel and flashing surfaces are not beingsubjected to exposed metal objects and materials left onthe roof such as: tools, material drop-off, fasteners, wire,staples, drill and nibbler chips, saw and file particles. Inthe process of rusting, these materials will absorb thepanel's protective coating, thus leaving the panelsexposed to rusting.

Check that the panels and flashing are not beingsubjected to long term wet conditions such as: standingwater, consistent sources of steam, mist, spray, drippingor runoff, wet debris, wet insulation or other moistureholding material.

Check that the panels and flashing are not subjected todirect contact or runoff from corrosive materials such as:copper pipes and flashing, uncured cement, treatedlumber, anti-icing chemicals, strong solvents or othercorrosive materials.

Check that graphite pencils were not used to mark onunpainted surfaces. The graphite marks can causerusting.

Check that the roof materials are not subjected todamaging heat such as: cutting torches, abrasive saws,etc.

L. UNSPECIFIED MATERIALSUse of the wrong materials may cause installation andperformance problems and may void the performanceand material warranties.

Check that all installed materials, especially sealants andfasteners, are only those which are provided or specifiedby Bigbee Steel Buildings, Inc. for your specific projectand are used only as specified on the erection drawingsand this installation guide.

Bigbee Steel Buildings, Inc. cannot be responsible for theperformance of roof materials that are not provided,specified or approved by Bigbee Steel Buildings, Inc.

H. RAKE SEALCheck that the sealant is in the correct position betweenthe roof panel and the lip of the gable trim

Confirm that the roof panel and gable trim are clean anddry during installation and that the sealant was not wet orcontaminated.

Check that the gable trim fasteners penetrate the centerof the sealant. Check that the fasteners are not loose orstripped.

I. SIDELAPCheck that the panel sidelaps are on module (held towithin the 1/8" panel width tolerance) and are assembledso that the male and female panel edges are properlynested together.

Check that the field installed sidelap sealant is in thecorrect position without voids or interruptions and is notdamaged, wet or otherwise contaminated.

Check that the panel coverage tolerance does not exceed1/8" per panel and that the accumulated coverage willallow proper fit and assembly of the peak sheets or peakflashing and any other critical fit conditions such aspenetrations, parapets, etc.

J. FLASHING AND PENETRATIONSCheck that all flashing (including penetrations) arecorrectly assembled and tightly fitted. Check that therequired sealants are correctly positioned and in completecontact with the adjoining surfaces without voids orinterruptions. Confirm that the sealants and adjoiningsurfaces are clean and dry during installation.

Check that the flashing splices are correctly lapped,sealed and fastened.

Check that the flashing is sufficiently pitched to shedwater and eliminate ponding areas, especially at thecritical splices, endlaps and corners.

Check that the fasteners are of the specified type, size,length, finish and spacing. Check that the fasteners arenot loose or stripped. Check that the sealing washers arein full contact with the flashing surface and not distorted,split or otherwise damaged.

9.0 ROOF INSTALLATION DETAILS9.1 GENERAL

The following details provide graphic illustration of theroof assembly steps. The purpose is to instruct theerector in correct and efficient assembly of the roofsystem.

Because of the many variations in conditions, it isimportant that you review the job to identify and isolatethe specific installation details required for your job.

Review the erection drawings for differences with thesedetails. If differences exist, the erection drawings haveprecedence.

These details are arranged in a step-by-step sequence.Following this sequence ensures correct assembly andensures that the part to be worked on will be readilyaccessible for the next assembly step.

Do not shortcut these assembly steps without carefulconsideration of the possibility of incorrect or omittedassembly and the resulting corrective rework.

To minimize confusion, the details are always oriented sothat the view is from eave to ridge, with the starting rakeat the left and finish rake at the right. Refer to theerection drawings to determine the required sheetingdirection and rake conditions.

To help ensure weathertightness, the details emphasizeproper fit-up, sealing and fastening. It is most importantthat only the specified sealants and fasteners be used foreach condition and that they be installed correctly asshown on these details and the erection drawings.

Be sure that these critical instructions are reviewed oftenand the roof assembly is checked at each assembly step.

This view shows the roof system oriented for a left-to-rightsheeting direction. For right-to-left sheeting, reverse theparts orientation.

The details in this section will show the installation of therake angle, eave trim, eave sealant and the first run ofinsulation. These are parts that must be installed beforethe roof panel installation can begin.

Caution: To assure proper fit-up of the sidelap assembly,proper fip-up of closures, flashing, curbs, etc., it isimportant that each panel be held to within the 1/8" panelcoverage tolerance and that overall coverage be checkedfrequently and any coverage error be corrected before itaccumulates.

Coverage must be checked at the eave and ridge andat every endlap.

To avoid accumulation error, the coverage measurementshould always be from the rake line or the starting roofpanel's seam.

To avoid measurement error, the measuring tape must befree and taut and must be parallel to the eave line or ridgeline.
