FRAME KIT INSTALLATION GUIDE
(TYPE SC3B AND SC3C FRAMES)
INTRODUCTION
This manual is designed to illustrate the basic steps involved in assembling and installing RoofScreen Pre-
engineered Frame Kits, Panels and Hat Sections offered in our Online Store. RoofScreen Frame Kits are not
engineered to be project specific and we make no claim as to the applicability to any specific field conditions.
PREPARATION
MATERIAL HANDLING
When receiving material, check to see that the shipping documents match the shipment. Count the number of
packages and quantities within each package to the extent possible. Check for damage at the same time. If damage
or other discrepancies are found, write a note to that effect on the bill of lading, and have it signed by the driver.
Tubing and hat sections for large orders may be delivered via flatbed truck in bundles with metal bands. For
Smaller orders, tubing and hat sections may be in wood crates and delivered via flatbed or enclosed trailer. Fittings
and hardware are packaged heavy cardboard pallet crates. These materials are heavy and will require a fork lift or
crane to unload.
!Do not lift bundles by the metal bands. Either use a fork lift from underneath, or use straps around the
entire bundle.
!Do not lift wood crates by the slats or cross members. Either use a fork lift from underneath, or use straps
around the entire crate.
!When using a fork lift, spread the forks as far as possible to balance the load. Drive slowly when moving
long bundles over uneven surfaces to avoid tipping the load.
!When using a crane or any other type of hoist, position the sling straps so that the space between the
straps is at least 1/3 the length of the bundle. Use sling straps with looped ends, running one end of the
strap through the loop at the other end to cinch the bundle when lifted.
!When setting the load on the roof, put wood blocks under it to protect the roof and allow space to
remove the sling straps.

!Heavy bundles and crates should be spread out on the roof to avoid overloading the roof structure. Place
the material directly over major supports such as beams or trusses.
!Bundles of tubing should be positioned parallel to the slope of the roof so they don’t roll down slope
when unbundled.
!Use caution when cutting metal bundle straps as the tension on the strap may cause it to spring up
potentially causing injury.
MATERIAL STORAGE
If the material is going to be stored outdoors for any period of time, we recommend covering it with plastic or
tarps. Bundles of tubing and hat section can be left uncovered if the load is raised at one end to allow water to run
off.
TOOLS
The following is a list of recommended tools to perform the installation:
1. 200’ tape measure
2. String line
3. 6” “Torpedo” level
4. Construction crayon
5. Ear plugs
6. Safety glasses
7. Heavy duty extension cords
8. Large Vice Grip Clamps
9. Open end and socket wrench set
10. Power drill
11. ½” drive power impact driver
12. Cordless drill/driver gun
13. Self-leveling laser level with tripod
14. Power skill saw with metal cutting blade
15. Reciprocating saw with metal cutting blade
INSTALLATION
REVIEW FRAME PARAMETERS
In the following sections of this installation guide we will cover steps involved in assembling frames and attaching
panels. To prepare, please review the assembled view of the frame in Figure 1. This drawing illustrates how the
frames are intended to be built. Height and Span are determined by choices made in the RoofScreen Frame Kit
Selection Guide found in our Online Store. Other dimensions shown in Figure 1 should be followed as closely as
possible to comply with maximum frame spacing listed in Table 1 of the Frame Kit Selection Guide. If for any reason

these dimensions cannot be achieved, the strength of the frame may be reduced, which could also reduce its
spacing capacity. If this occurs, additional engineering review is recommended.
The cantilever is designed to allow front-to-back adjustment during installation. The cantilever distance can range
from 1’-1” to a maximum of 1’-6”. Frames should be assembled so that when they are adjusted, the maximum
cantilever on any given frame is 1’-6” or less.
Tubes (labeled “H”, “V” and “D”, for horizontal, vertical and diagonal) are pre-cut to fit the frame per dimension
parameters shown in the drawing, and include crimped ends where shown. If any dimensions in the frame are
increased, the tubes may be too short to fit.

ASSEMBLE FRAMES
STEP 1: INSTALL BASE SUPPORTS
Lay out the RoofScreen and determine the location for each
frame. Base Supports should be installed in a straight line if
possible, but it doesn’t have to be perfect. Frame cantilever
discussed in the previous section will allow some adjustment
during frame installation to make up for a few inches if
necessary. It is recommended to use string lines or a laser level
in vertical mode to ensure all Base Supports are in a straight
line.
Base Supports are designed to mount to structural members in
the roof. Due to the vast number of variables in field
conditions, neither hardware nor methods for making this
attachment are included in the Frame Kits. The bottom plate in
the Base Support has pre-punched holes to accommodate up
to twelve ¼” fasteners, and five 3/8” fasteners (see Figure 2).
Here are some typical methods of attachment:
•Wood Lag Screws: (2 or 3) 3/8 x 6” lag screws installed
in the .470” holes, arranged in line with the wood
beam below.
•Tek Screws: (4) #14 diameter self-drilling Tek screws
installed in the .313” holes, fastening into I-beam or
open web steel joist below.
•Concrete Anchors: (2 or 4) 3/8 diameter concrete
anchors or expansion bolts with 3” to 5” embedment,
installed in the .470” holes.
•Through-bolts: (2) 3/8 through-bolts installed in the
.470” holes.
STEP 2: INSTALL FLASHING AND ROOFING
After all Base Supports are installed, have a qualified professional roofing contractor install the Flashings over the
Base Supports and roof them in with appropriate method for the type of roofing system being used. If hot asphalt
or a liquid applied system is being used, it is recommended to cover the threaded holes at the top of the Base
Supports with duct tape. This will prevent material from clogging the holes and making it difficult to thread the
bolts when installing Base Assemblies.
Either the roofer or RoofScreen installer should adjust the height of the Flashing Boots to account for thickness of
roofing and insulation. Flashing should terminate as closely as possible to the top of the Base Support, but not
more than ½” below.

STEP 3: INSTALL GASKETS AND BASE ASSEMBLIES
With all Base Supports installed and roofed in, install the Base Gaskets over the flashings. The gasket strip is self-
adhering and has a removable backing. Peel the backing off and stick the gasket on the outside of the flashing,
flush with the top. The gasket is not meant to be pulled or stretched during installation, however it may be
necessary to stretch it slightly at the end so the ends meet evenly.
After the Gaskets are in place, install a Base Assembly, Part# A10, on each Base Support (see Figure 3). A10
Assemblies are attached with (8) Bolts with Poly Washers, Part# B11. The bolts thread into pre-tapped holes in the
top of the Base Support. Start the bolts by hand, threading each one a few turns to make sure they are not cross-
threaded. Once all 8 bolts are started, tighten the bolts moving in a crisscross pattern similar to tightening lug nuts
on a car wheel.
At this time, do not tighten the large bolt in the RotoLock as shown in Figure 3.
STEP 4: INSTALL HORIZONTAL TUBES
Locate the horizontal tubes labeled “H”, and Field Connectors Part# C12. Attach the field connectors to the
crimped ends of the tubes with a ½” diameter bolt, nut and lock washer, Part Numbers B13, N10 and W10 (see
Figure 4).

Slide the tube through the Base Assemblies as shown in Figure 5. To ensure the wall is straight when complete, it is
critical that the C12 Field connectors installed on the horizontal tubes are in a straight line along each segment of
the RoofScreen. This is done by sliding the horizontal tubes in or out of the Base Assemblies. For short runs, use a
string line for this step. The most effective method is to set the tubes on the first and last frames in a run, then pull
a string line between the two to set the remaining tubes. If the run is long (over 50’), or if it is a windy day, it is
recommended to use a laser level in vertical mode instead of a string line. Remember the frame cantilever is
limited to 1’-6”, as shown in Figure 5.
Once all horizontal tubes are properly aligned, install (4) Self-Drilling Tek Screws, Part# S10, in each Base Assembly.
Before these Tek Screws are installed, it is important that the C12 connectors are oriented vertically to allow the
Vertical Tube (installed in the next step) to be vertical and plumb.
Next, install (3) Thread-Cutting Screws (Part# S44) in the aligned holes of the RotoLock feature of the Base
Assembly (see Figure 6). Install (1) screw from the opposite side as illustrated in Section AA of Figure 6.
To finish this step, tighten the center bolt in the
RotoLock feature. This bolt, as all bolts in the
RoofScreen system, only need to be reasonably
tightened and do not need to be torqued to any
specific setting.
Important: Be sure to sweep or vacuum metal
shavings from the top of the Base Assemblies after
drilling Tek Screws to prevent rust from forming on
the shavings. The Base Assemblies are stainless
steel, so no harm will come to them from rusted
shavings. However, it is not aesthetically pleasing
and the end customer may think the parts are
rusting.

STEP 5: INSTALL VERTICAL TUBES
Referring to Figure 7, locate the vertical tubes labeled “V” and install them on the first and last frames in a straight
run as follows. Slip the tube into the C12 Connector installed in the previous step. Hold the tube in position with
the top of the tube at the desired height and secure it with (4) Tek Screws, Part# S10, through the pre-punched
holes in the C12 Connector. If the tubing does not easily fit into the C12 Connector, try loosening the bolt to allow
the Connector to expand. Tighten the bolt in the C12 Connector when the tube is secured in place.
Depending on how tall the vertical tube is, it may stand up on its own at this point simply by tightening the bolt in
the C12 Connector. If not, you may have to install the diagonal tube as well to keep it in position. If this is the case,
skip to Step 6 for the first and last frame in the straight run, then return to this step for the remaining frames.
To install the remaining vertical tubes, pull a string line from the top of the first frame to the top of the last frame.
Install each vertical tube as described above, using the string as a guide for the top of tube height. If these tubes
are too tall to stand up on their own by tightening the bolt in the C12 Connectors, it is okay to let them lay down
on the roof until the next step.
STEP 6: INSTALL DIAGONAL TUBES
Locate the diagonal tubes labeled “D” and install the C12 Field Connectors and C15 End Connectors as shown in
Figure 8. Make sure the fittings are properly aligned to each other so they will fit on the frame correctly. Next, slide
the upper end with the C12 Field Connector over the vertical tube and connect the lower end with the C15 End
Connector to the fin on top of the A10 Base Assembly.

Using a level on the face of the vertical tube, make sure it is plumb by sliding the C12 Field Connector up or down.
Once the vertical tube is plumb, fasten the C12 Connector to the vertical tube with (4) Tek Screws as shown in
Figure 9.

LATERAL BRACES
Lateral braces, typically used at corner conditions, resist forces in the lateral direction of a RoofScreen. They are
designed to connect to the top of the vertical tube on a frame being braced, to the low end of an adjacent frame.
If Lateral Braces are being used, locate tubes labeled “LB”. On each tube, install a C12 Field Connector on the
crimped end as shown in Figure 10.
Install a C12 Field Connector and a C15 End Connector on the low end of the frame adjacent to the braced frame
as illustrated in Figure 10. Slip the crimped end of the brace tube with the C12 Connector attached, onto the
vertical tube of the frame being braced, but do not fasten it with screws at this point. Hold the low end of the
brace tube next to the C15 Connector installed on the low end of the vertical tube of the adjacent frame, and mark
the tube to be cut so it will slip all the way into the fitting.
Cut the brace tube to the marked length and slip it into the C15 Connector (this may require sliding the C12
Connector on the upper end of the tube up slightly to allow it to insert into the C15 Connector at the lower end.
Once the lateral brace is in position, secure the fittings with S10 Tek3 Screws and tighten the bolts (see Figure 11).

INSTALL HAT SECTIONS
If panels are to be installed in horizontal orientation, please skip this section.
3” deep, 16ga galvanized Hat Sections,
Part# H13, mount horizontally across the
frames and become the attachment
supports for vertically mounted panels.
To install the Hat Sections, hold the
vertical frame tubes plumb and fasten
the Hats with (4) Tek3 Screws. As shown
in Figure 12, Hat Sections should be
mounted to the vertical tube, positioned
over the C12 Connectors at the
connections of the horizontal and
diagonal tubes. If for any reason the
Hats cannot be positioned over the C12
Connectors, the strength of the frame
may be reduced, which could also
reduce its spacing capacity. If this
occurs, additional engineering review is
recommended.

Hat Sections are supplied in 20’ lengths. They are joined end to end with Hat Splices and Tek screws as shown in
Figure 13. Splices can be at any point along the screen and do not need to be located over a vertical frame tube.
INSTALL PANELS (VERTICAL ORIENTATION)
If panels are to be installed in horizontal orientation, please skip to next section.
As illustrated in Figure 14, vertically oriented panels
are mounted to the Hat Sections installed in the
previous step. Panel extension past the upper and
lower Hat Sections should be equidistant. Panels
should be fastened to Hat Sections with screws
appropriate for the type of panels being installed.
Ribbed style panels are fastened through the face of
the panel and use color matched screws, Part# S16.
Concealed fastener panels, such as Flush Panels, do
not need color matched screws and can use standard
Tek3 screws, Part# S10.

To keep panels level at the top during installation, use a nylon string line stretched end to end on each straight
section of screen. To use the string, you must first install the starting panel. Start at one end and screw in the first
panel at the correct height. Use a level to ensure it is perfectly plumb. Next, install a vertical support on the
opposite end of the wall to support the other end of the string at the correct height (a 2x4 clamped on the Hat
Sections with Vice Grip clamps works well for this). If the run is long, or it is windy, this may need to be done in
shorter segments. Attach the nylon string line to the top of the first panel installed, and pull it to the vertical
support on the opposite end. Stretch it as tight as possible and sight down the string to make sure it does not sag.
Install the remaining panels, sliding each one up to the string, but do not touch the string. This is important
because if the panels push the string up even a fraction, your panels will start to go uphill. When you come to the
end of a wall or a corner, the method used to terminate the panels will depend on the type of panel being used.
Here are a couple of general guidelines:
THROUGH FASTENED RIBBED PANELS:Simply cut the last panel with a metal cutting skill saw to the width
necessary to fill the gap between the last full panel and the corner. Trim it out with color matched corner trim.
STANDING SEAM OR FLAT WALL PANELS:Cut the last panel to the proper width and either screw a stiffener
channel on the flimsy (cut side) of the panel, or use a hand seamer to bend an edge. This will allow for a straight
edge to fasten the corner trim.
INSTALL PANELS (HORIZONTAL ORIENTATION)
As illustrated in Figure 15, horizontally
oriented panels are mounted directly to the
vertical frame tubes. Frame Kits are
designed for panels to be evenly distributed
on the full length of the vertical tube, with
equidistant cantilever past the upper and
lower C12 Connectors. Horizontal Panels are
typically ribbed style and should be fastened
through the face of the panel with color
matched screws, Part# S16, (1) screw per
panel down-flute.
Depending on the screen height, multiple
horizontal rows of panels may be required.
Install the lower row first and upper row(s)
last. To terminate the top of the panel at
the desired screen height, overlap ribs on
the panel below, or cut the top of the panel
to the desired height.

As illustrated in Figure 16, panel end laps must fall on vertical frame tubes and cannot be lapped mid-span. It is
recommended to allow 6” of overlap to allow adjustment if necessary.
PANEL
TRIM
Once all panels are installed, finish trims can be installed on the top, corners and end conditions to provide a clean,
finished look. Methods for installing trims depend on the type of panels being used, as well as the style of trim.
Typically, a trim cap is installed along the top edge of the panel, fastened approximately every 36” with S16 color
matched screws. Corner trim and edge trims are typically fastened approximately every 12”, also with S16 screws.
Please see additional documentation in the Online Store for the style of panels and trims being installed.
COMPLETION
After the entire system is installed, do a final quality check to ensure all screws are installed and bolts are
tightened. Pick up any screws or scrap metals left on the roof to prevent damaging the roof membrane should
someone step on them.
