IMPORTANT INFORMATION

THIS MANUAL IS DESIGNED TO BE UTILIZED AS A GUIDE WHEN INSTALLING THE SNAP-LOC 24

ROOFING SYSTEM. IT IS THE RESPONSIBILITY OF THE ERECTOR TO ENSURE THE SAFE INSTALLA-

TION OF THIS PRODUCT SYSTEM.

SAFETY

STUDY APPLICABLE OSHA AND OTHER SAFETY REQUIREMENTS BEFORE FOLLOWING THESE

INSTRUCTIONS.

The installation of metal roof systems is a dangerous procedure and should be supervised by trained

knowledgeable erectors. USE EXTREME CARE WHILE INSTALLING ROOF PANELS. It is not possible for

Metal Sales to be aware of all the possible job site situations that could cause an unsafe condition to

exist. The erector of the roof system is responsible for reading these instructions and determining the

safest way to install the roof system.

These instructions are provided only as a guide to show a knowledgeable, trained erector the correct

parts placement one to another. If following any of the installation steps would endanger a worker, the

erector should stop work and decide upon a corrective action.

Provide required safety railing, netting or safety lines for crew members working on the roof.

Do not use the roof panel as a walking platform. The roof panels will not withstand the weight of a

person standing at the edge of an unseamed panel. Provide walking platforms for crew members

required to walk on the roof before it is seamed.

Do not stand on the roof panel at the ends until the panel has been attached with fasteners.

TECHNIQUE

RECOMMENDED TOOL TYPE - Use depth locating nose or adjustable clutch on screw gun to prevent

overdrilling and strip out.

SEATING THE WASHER - Apply sufficient torque to seat the washer - do not overdrive the fastener.

FASTENER INSTALLATION

DO NOT USE IMPACT TOOLS OR RUNNERS.

CORRECT

Sealing material slightly visible

at edge of metal washer.

Assembly is watertight.

SELF DRILLERWOODSCREW

TOO LOOSE

Sealing material is not visible;

not enough compression to

seal properly.

TOO TIGHT

Metal washer deformed;

sealing material pressed

beyond washer edge.

TO PREVENT WOBBLING - Make sure fastener head is completely engaged in the socket. If the head

does not go all the way in the socket - tap the magnet deeper into the socket to allow full head engage-

ment. Metal chips will build up from drilling and should be removed from time to time.

PROTECT DRILL POINT - Push only hard enough on the screw gun to engage clutch. This prevents

excess friction and burn out of the drill point. Correct pressure will allow screw to drill and tap without

binding.

DRILLING THROUGH SHEET AND INSULATION - Ease up on pressure when drilling through insulation

to avoid striking the purlin or girt with the point - apply more pressure after drill point contacts purlin

or girt.

DRILLING THROUGH PURLIN OVERLAPS - Drilling through lapped purlins requires extra care. Exces-

sive voids between purlins sometimes damages drill points and two self drillers might be necessary to

complete the operation. It is sometimes advantageous to predrill.

CONDITION OF SUBSTRUCTURE

Whether over solid substrate or open structural framing, panel distortion may occur if not applied

over properly aligned and uniform substructure.

The installer should check the roof deck for squareness before installing Snap-Loc 24 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). Then by measuring diagonally between the two points

established, the dimension should be exactly a module of five (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.

VENTILATION

DESIGN / INSTALLATION CONSIDERATIONS (CONT.)

Proper design and installation of vapor barriers and ventilation systems are important to prevent

condensation and the resulting problems of moisture damage and loss of insulation efficiency.

Condensation occurs when moisture laden air comes in contact with a surface temperature equal to or

below the dew point of the air. This phenomenon creates problems that are not unique with metal

buildings; these problems are common to all types of construction.

The underside of the metal roof on a typical metal building (no attic) should be protected from con-

densation by insulating with a faced insulation. This should reduce the potential of condensation

forming on the underside of the panels.

On buildings that have an attic space or are being retrofitted with a metal roofing system, vents should

be placed at both the eave and peak of the roof in order to prevent a buildup of moisture (humidity) in

the attic space.

SNAP-LOC 24

INSULATION

DESIGN / INSTALLATION CONSIDERATIONS (CONT.)

In most cases insulation is installed directly under the roof panels. Insulation is recommended on all

applications to act as a sound barrier, prevent condensation, and increase insulating value of a roof

system. Roof panels installed over open framing without insulation will cause excessive roof noise.

It is recommended that either urethane thermal blocks or 1

1

/2" blanket insulation be used as illustrated

to minimize noise potential.

Many different types of insulation can be used with the metal roof panels. Blanket, batt, rigid, and

reflective insulation are just a few. Please contact your insulation supplier for specific recommenda-

tions on type of insulation, vapor barriers, and installation procedures.

When applying a compressable type of insulation over open framing members, rigid thermal blocks

can be used to help eliminate heat lost at purlin locations. See chart on page 17 for available Thermal

Block systems.

CAUTION

Use extreme care when working next to insulation. The insulation will provide a

false sense of security by hiding the view of the ground below the insulation.

SYSTEM EXPANSION / CONTRACTION

Steel roofing panels are subject to dimensional changes after installation due to exposure to varying

temperatures. The greatest influence is solar energy. Steel roofing absorbs various amounts of heat

depending upon color, finish, angle of exposure, and time of exposure.

The relationship of ambient temperature to building structural temperature must be considered when

designing a Snap-Loc 24 roof system. The floating clips for the Snap-Loc 24 panels are designed for

expansion and contraction of the panels in the longitudinal direction. Lateral expansion and contrac-

tion is accomodated by the configuration of the panel cross section and causes negligible panel

movement.

When the total length of panel run exceeds the capability of the floating clips to accomodate the

thermal movement, expansion joints must be designed into the structure.

- The floating clip allows the roof surface (panels) to move independently of the roof substructure to

allow for thermal expansion and contraction. These clips are designed with a vertical tab that slides

along the base section of the clip. Clips are placed along the male leg of each panel prior to installing

adjacent panels. Design wind uplift requirements must be considered for proper clip spacing

- The fixed clip does not allow the roof surface (panels) to move independently of the roof substructure

allowing for thermal expansion and contraction. These clips are only recommended for buildings

LENGTH - Minimum factory cut length is 5'-0" on panels. Maximum recommended panel length is

45'-0". Longer panels require additional consideration in packaging, shipping, and erection. Please

consult Metal Sales for recommendations.

There are three critical measurements involving roof panels: the length of overhang required at the

eave, the offset at the peak end, and the position of the panel endlap (if required). In each case a certain

measurement is required. Check each measurement to ensure panel placement gives you the distance

required at the eave, peak and endlap condition (if required). In most cases any variance can be taken

out at the eave and peak.

BASED ON MAXIMUM SLOPE OF 4:12.

INSTALLATION DIRECTION

DESIGN / INSTALLATION CONSIDERATIONS (CONT.)

Snap-Loc 24 can be installed on each roof plane from left to right as shown in option #1. Snap-Loc 24

accessories are fabricated to allow the installer to begin work on the left side of the building, continue

across the ridge, and work to the right side of the building, option #2. However, if endlapping of panels

is required, panels must be laid from left to right.

INSTALLATION OPTION #1 INSTALLATION OPTION #2

PANEL ENDLAPPING

If panel endlapping is required, endlaps are to be applied in one continuous line. This allows the cinch

straps to complete full coverage of the Snap-Loc 24 panel. See page 35-37

FACTORY NOTCHED/PUNCHED PANELS - Unless otherwise specified, Metal Sales provides all Snap-

Loc 24 panels with factory rib notching and fastener hole punching on both panel ends. This elimi-

nates reliance on field notching for weathertight seams at panel endlaps and ease of fastener hole

alignment. Panels that are not to be factory notched/punched must be specified at time of order.

RECEIVING MATERIAL

HANDLING MATERIAL

It is the responsibility of the installer to unload material from the delivery truck. The installer shall be

responsible for providing suitable equipment for unloading of material from the delivery truck.

After receiving material check their condition and review the shipment against the shipping list to

ensure all materials are accounted for. If damages or shortages are discovered, it should be noted

on the Bill of Lading at the time of delivery. A claim should be made against the carrier as soon as

possible. Metal Sales is not responsible for any damages or shortages unless they are documented

in writing and presented to Metal Sales within 48 hours.

GENERAL HANDLING

CAUTION

Improper loading and unloading of bundles and crates may result in bodily harm and/or

material damage. Metal Sales is not responsible for bodily injuries and/or material

damages resulting from improper loading and unloading.

Each bundle should be handled carefully to avoid being damaged. Care should be taken to prevent

bending of the panel or abrasion to finish. Whenever possible, the bundle should remain crated until

it is located in its place of storage. If bundles must be opened, we recommend you recrate them

before lifting. To avoid damage please lift the bundle at its center of gravity.

MECHANICAL HANDLING

FORKLIFT - A forklift may be used for panels up to 20'-0" long. Please make sure the forks are at their

maximum separation. Do not transport open bundles. When transporting bundles across rough

terrain, or over a longer distance, some means of supporting the panel load must be used.

CRANE - A crane should be used when lifting panels with lengths greater than 20'-0". Please be sure to

utilize a spreader bar to ensure the even distribution of the weight to the pick up points. As a rule

when lifting panels, no more than

1

/3 of the length of the panel should be left unsupported. Never use

wire rope because this will damage the panels.
