Installation 

AEP Span’s’ Klip-Rib ® shall be fastened with appropriate 

screws to supports as per manufacturer’s recommendations 

(see page 6) or as called for on the 

Contract Documents. Steel supports should be galvanized 

or painted. Sheets shall have side laps facing 

away from the prevailing weather. 

Sheeting shall project a minimum of 1 1/2 inches 

into gutters. The maximum projection into the gutter 

should allow access for cleaning. 

When installing Klip-Rib ® over purlins and blanket 

insulation, the maximum insulation thickness is 4 

inches. The maximum recommended span between 

supports is 5’0”. This span should be reduced in 

severe wind conditions (negative load) or heavy snow 

loads (positive load). Contact your AEP Span’ representative 

with special conditions. 

Installation of panel sidelap sealant (see Figure 

1, page 5) is recommended for roof slopes less than 

2:12 (minimum slope 1:12) or project conditions with 

potential ice damming or snow loads greater than 

30psf. 

Flashings are to be made from like finish or 

compatible materials as designated. High-side flashings 

should cover the sheets a minimum of 4 inches. 

Flashing attachments and caps are to be made with 

mechanical fasteners. Provide sealant at all trim laps 

and as shown in the Klip-Rib ® Flashings and Details 

Guide and/or the Contract Documents. Roofs, 

flashings, and gutters shall be swept clean of all debris 

(nails, screws, cuttings, filings, etc.) at the end of each 

day’s work, and on completion of installation. The job 

shall be left clean and in a weather-tight condition. All 

sheating is to be installed by experienced craftsmen. 

Note: Designers should consult AEP Span regarding 

the length limitation caused by transport, and practical 

considerations if roofing panels exceed 60 feet. 

Special Tools For Installing Klip-Rib ® 

Special tools are required for the correct installation 

of Klip-Rib ® . The turn-up/turn-down tool is used for 

two purposes. 

The turn-up feature is used for turning up the 

sheet trays under the flashing at the high end of the 

roof. This helps prevent any moisture from draining 

into the building which might accumulate under the 

flashing. The turn-up procedure can be done before 

installing the sheets or after the sheets have been fastened 

in place if panels are installed over purlins. In 

the latter case, a clearance of approximately 3 inches 

is required at the end of the sheets to allow room for 

the turn-up tool. 

The turn-down feature is used to turn down 

the pan of the 

panel at the 

low or gutter 

end of the roof. 

This turn-down 

or drip edge 

helps prevent 

water from 

running back 

along the underside of the sheets and adds additional 

strength to the panels while eliminating “bowing” of 

the trays. Refer to page 8 for proper use of this tool. 

A notching tool is used for on-site notching of 

flashings perpendicular to the ribs. After the KIip-Rib ® 

sheet has been fastened and the sheet ends turned 

up, the flashing should be placed in correct position 

while notching. The lower handle of the notching 

tool is placed along the top of the rib with the notch- 

2 

October 2007



ing lugs 

on top of 

the rib. 

The top 

handle 

is then 

raised to 

its full 

extent and the jaw of the tool is pushed onto the flat 

edge of the flashing as far as it will go. Closing the 

handles will then notch the flashing in line with the 

sheet rib. This procedure is repeated on each rib for 

the full length of the flashing. 

Preparation Instructions for 

Klip-Rib ® Installation 

1. Check that the top flanges of all purlins or supports 

are lying in plane. Accurate alignment assures efficient 

locking of sheets and clips. Misalignment can interfere 

with the locking action, particularly where clips are 

closely spaced. 

2. To maintain maximum holding power and avoid 

interference when attaching the ridges, clips should 

be 8”-10” from the top end of the sheet and at least 

3” from the bottom end. The high-side trim should be 

fastened 8” on center. 

3. Make spot checks for the alignment of sheets during 

erection to control creeping. To rectify alignments, 

sheets may be adjusted 1/8” by pulling the clip away 

or pushing it towards the sheet while fastening the 

clip. 

4. All panels must be “fixed” with fasteners to resist 

drag loads. These fasteners are typically installed 

through the panel into the purlin or substrate under 

the trim at the high side of the roof. Refer to the “Drag 

Load” tables found on page 25 for type and quantity 

of fasteners suitable for your project conditions. 

5. Suitable soft-soled work shoes must be worn when 

walking on the roofing sheets. The soles must be of 

a type that will not pick up stones and other abrasive 

materials that could damage the surface of the sheets. 

6. It is the responsibility of the installer to take proper 

safety precautions that are in compliance with state 

and local guidelines. Special attention to safety should 

be given to roof perimeter areas and installation over 

open framing. 

Fastening Method 

Clip fasteners shall be installed in the two outbound 

clip holes. 

When four 

fasteners are 

required, 

the two 

incremental 

fasteners 

are installed 

in inbound 

holes (one each side). For attachment recommendations 

in severe wind environments, contact your AEP 

Span representative. See “24 ga Fastener Guide” on 

page 6 for recommended fasteners. 

Neoprene Closures: Neoprene bottom closures 

should be placed during the installation of the roof 

panels at 

the bottom 

of 

the slope 

and 

should 

be 

secured 

in place 

with the use of gunnable grade sealant between the 

flashing and the neoprene closure. Neoprene top closures 

should be used under flashings and on top of 

the roof panels to fill the void of the roof panel trays. 

The top neoprene should be positioned such that the 

fasteners (spaced at 8” center to center) attaching the 

flashing to the Klip-Rib ® ribs, pass through the closure 

to secure it in place. Sealant should also be used 

between the closure, roof panel, and flashing trim.

Sheet Laying Procedures 

Step 1: When lifting Klip-Rib ® sheet lengths onto the 

roof frame, make sure all sheets have the female rib 

facing towards the side where fastening is to begin. 

Attach the first run of the fastening clips using the 

appropriate fastening method and fasteners. Make sure 

that the clips are in line and located so that the sheets 

will be laid correctly in relation to other building elements. 

NOTE: Lifting of panel bundles with long panel 

lengths may require use of a “spreader bar” to avoid 

damage to roof panels. 

Step 1 

Step 3 

Using the 

appropriate 

fasteners, 

secure the 

clip to the 

purlin or 

deck substrate. 

Should the clip position coincide with a male rib 

spur, deform the spur with a blow from a rubber mallet 

so that the clip will seat comfortably over the rib. 

Step 2: Lay the first sheet over the fastened run of clips 

by positioning the center rib first. Seat the center and 

female ribs onto all clips by pressing down the center 

Step 2 

rib and then the female rib over each fastening clip 

along the full length of the sheet. When positioning 

this sheet, make sure the overhang at each end is correct. 

Step 3: The clip has a short leg and a long leg. Position 

the short leg of the fastening clip over the male rib 

of the fastened sheet. The clip has a notch in the leg 

that goes over the male rib of the previous panel. The 

clip has to be “rocked” onto the male leg to engage 

the notch onto the terminating edge of the male leg. 

Step 4 

Step 4: Place the second sheet over the second run 

of fastening clips, again positioning the center rib first, 

and then push the female rib down over the male rib 

of the first or preceding sheet. Be sure that the ends of 

the sheets are in line. 

Step 5: On shorter spans, the panel may be clipped by 

first walking along the center rib and then the female 

rib. However, a rubber mallet will be required for 

longer roofing 

spans 

and for walls. 

Clip both ribs 

over fastening 

clips at 

supports and, 

while walking 

or press- 

4 

October 2007



ing on the panel being laid, strike its overlapping rib 

with short, sharp mallet blows. Repeat procedure as 

required between supports. 

Full interlocking of the ribs is essential and the free 

edge of the male rib must engage on the shoulder of 

the female rib. This should be checked by standing 

at midspan close beside the male leg of the previously 

laid sheet. If it disengages, snap with the mallet. 

Repeat Steps 3, 4 and 5 for subsequent panels. 

Step 6: If the space left between the last sheet and the 

fascia is less than half a sheet width, it will be covered 

by fascia flashing. In this case, cut fastening clips in 

two using the short leg half, secure the male rib at 

each purlin. If the space left between the last sheet 

and the edge of 

the roof is more 

than half a panel 

width, the sheet to 

be replaced should 

be cut to the width 

required and 

placed as in Steps 

3,4 and 5. 

During clean-up, make sure there are no metal 

particles from drilling, filing, etc., remaining on the 

roof. Cutting sheets with power saws on top of other 

sheeting should be avoided. 

Roofs, flashings, and gutters should be swept 

clear of all debris at least at the end of each work day 

and upon completion of the installation. Corrosion 

and possible failure of the zinc/aluminum coating 

may occur when lead or copper-based materials are 

allowed to remain in contact with Zincalume ® surfaces 

under moist conditions.

NOTE: For severe conditions, field install 

gunnable butyl sealant as indicated above. 

Failure to take this precaution will result in unsightly 

staining of the Zincalume ® coating as particles oxidize 

during exposure. 

Klip-Rib ® roofing and siding will perform as specified 

if installed in accordance with the recommendations 

set forth in this literature. 

Handling and Storage 

Handling and storage are important to the performance 

of the Klip-Rib ® system. Bundles must be kept 

dry in transit and stored under cover, clear of the 

ground, to prevent water and/or condensation from 

being trapped between adjacent surfaces. If bundles 

become wet, sheets should be separated, wiped clean 

with a clean cloth without delay and placed so that 

air circulation can complete the drying process. These 

procedures are recommended to avoid possible deterioration 

of the coating which could lead to reduced 

life expectancy or poor appearance. 

Strippable Coating: Avoid exposure to direct sunlight. 

Remove strippable film as panels are installed. 

Touch-Up Painting: Application of touch-up paint 

to damaged paint areas that involve minor scratches 

is not recommended. Panels or trim that have severe 

paint and/or substrate damage should be replaced. 

Touch-up painting is not recommended due to differential 

fade and weathering characteristics of factory 

and field-applied paint systems.

Notes to the Designer/User 

The details contained in this book are intended to 

be design aids. Actual conditions will vary and all situations 

have not been taken into account. Modifications 

to suit actual conditions are the responsibility of the 

designer/user. If product application is in high snow 

load conditions, please contact an AEP Span representative. 

Flashings: The standard style flashing has been 

depicted in all the details, although other details can 

be made to suit your aesthetic needs. Flashings which 

are fastened together must allow for expansion and 

contraction of materials and may require expansion 

joints where their total combined length exeeds 40 ft. 

See SMACNA manual for details. Heavy snow conditions 

require special design consideration and some 

details in this manual, such as valleys, may be in appro 

pri ate. Details shown are for applications over solid 

decking and are similar for applications over open 

framing (purlins) and rigid insulation. The dimensions 

shown on the flashing details in this book are suggested 

dimensions. They can be altered to suit specific project 

conditions. Certain panel and flashing details, such as 

panel overhangs, gutters, eaves, rakes, etc. can be easily 

damaged if a ladder is leaned against them. Care must 

be taken to avoid this. Penetrations, such as vent pipes, 

skylights, chimneys, etc. may require that support framing 

be added to maintain structural integrity and watertightness 

at these areas. To achieve optimum aesthetic 

appeal, the installer should determine a panel layout 

which permits the flashings running parallel to the roof/ 

wall panel (e.g. rake, outside corner, etc.) to be of equal 

size at both ends of the roof and walls. 

Condensation Control: It is the designer’s responsibility 

to determine the need and composition of condensation 

control material, including insulation, vapor 

retarders and/or venting. Metal roofing is susceptible 

to condensation and its control should be carefully 

considered. An AEP Span representative is available to 

assist in determining the condensation control requirements 

of your specific project. 

Underlayments: Minimum requirement is 30 lb. felt 

or two layers of 15 lb. felt.

October 2007



Valleys: Valley dimensions must be the proper width 

to account for slope, snow, ice and rain conditions. 

Valleys and eaves may require a special underlayment, 

as they are susceptible to water build-up and 

ice-damming. If ice or water backs up, water intrusion 

may occur. An underlayment such as a cold-applied 

membrane should be put down first, extending 4’-0” up 

from the center of the valley on each side and the same 

distance up from the eave. The 30 lb. felt should then 

overlap this membrane. 

flashing trim allowing a tab to be placed between the 

ribs to create a wind and weather block. 

Turn-up/Turn down tool: is used to “turn-up” the 

panel pans at the upper end of the panel, before the 

panels are installed to form a dam at the end of the 

panel which guards against water in fil tra tion due to 

wind-driven rain. The turn-down feature is used to “turn 

down” the pans at the lower end of the panel after it has 

been installed minimizing the problem of water wicking 

back un der neath the panel. See page 8 for proper use of 

this tool. 

Closures: Closures on the ridge are held in place by 

the fasteners that attach the ridge flashing to the Klip- 

Rib ® panel. Closures should be caulked top and bottom 

with gunnable sealant if the slope 7/32” is DIA less than 3:12. 

(6 PL) 

All closures at eave and valley conditions should be 

caulked to the eave or valley flashing, but not to the 

2 1/2” 

panel. Expansion and con trac tion is taken out at the 

eave, however, the panel needs to be 9” able to slide over 

the closure.

Application: Klip-Rib ® is secured to the substrate 

using concealed clips and does not act as a di a phragm. 

An al ter na tive bracing or diaphragm system must be 

employed to transfer the required shear loads. The panel 

must also be pinned at the ridge to resist the ‘drag’ load 

caused by snow loads, live loads, thermal move ment 

and gravity. The intensity of the drag is a function of the 

slope, the loads and the length of the sheet. Appendix 

“A” gives the drag loads for various slopes and loading 

conditions Appendix “B” gives lateral resistances for 

different materials and fastener types. Klip-Rib ® can be 

installed over wood, steel framing or rigid insulation. 

When installed directly over rigid insulation intermittent 

supports are not required. However, perimeter structural 

members are needed for pinning the panel at the ridge 

and for support under flashings. It is not rec om mended 

that Klip-Rib ® be used on slopes of less than 1:12, 

es pe cial ly in snow areas. Keep roof penetrations to a 

minimum. 

All flat metal surfaces can display waviness commonly 

referred to as “oil canning”. This is caused by steel mill 

tolerances and variations in the substrate and roofing 

underlayments. Darker colors will accentuate oil canning 

more than lighter, more neutral colors. However, 

Klip Rib ® resists oil canning better than most panels due 

to its rib spacing and the minor ribs in the panel trays. 

Oil canning is an inherent characteristic of flat steel 

products, not a defect, and therefore is not a cause for 

panel rejection. 

Contact your AEP Span representative if you have any 

questions about the use or installation of Klip-Rib ® and 

its accessories.

Notes: 

1) Multiply the sheet length by the drag load indicated in Appendix A to determine the total drag load on the 

sheet. 

2) #12-14 x 1” Impax SD values are based on a 16 gauge minimum substrate. 

3) 1/4-14 x 7/8“ Lap Tek values are based on a 22 gauge minimum substrate. 

4) #14 x 1” Type A values are based on a minimum 1/2” C-D plywood or 1” nominal Doug-Fir. 

5) Match the drag load figured from Appendix A with the load for the correct substrate in Appendix B to 

determine the number of fasteners required per panel. Place fasteners as shown in the preceding details. 

6) Fasteners must be located a minimum of 1” from each other and from the end of the panel.
