Safety Guidance
- Always wear the proper OSHA approved
safety equipment when working on a roof .
- Safety equipment should be checked
annually for wear and quality.
- Always wear proper eye protection.
- When walking on the roof avoid walking
on installed rails. If this is unavoidable check
L-feet for fatigue before final installation.
- Appropriate fall protection gear should
be used. Extreme caution should be
used when near the edge of the roof.
Series 100 UL
Roof Mounted System
How to Configure Your System
First calculate the spans and penetration count. See span
tables in structured engineering letters under the resources
tab of the SnapNrack website. Determine site conditions:
general building height, array pitch, the wind speed, and
snow load or topographical condition. Find appropriate
railspan from table.
Span Table Example
*CS-Consult
Structural Engineer Notes
- The UL Listing covers bonding
for a load rating up to 45 psf.
- See Appendix A for the list of modules
that have been tested with the Series 100
UL system.
- These systems have been evaluated
for module to system bonding, only to
the requirements of UL Subject 270.
- This system has also been
evaluated for a Class A System Fire
Classification for a steep-sloped roof
with Type 1 and Type 2 modules.
- Installing Contractor is responsible for
verification that attachments to roof
framing are fully engaged into appropriate
structural member and that structural
member is adequate for support of roof
mounting component and associated loads.

Survey the Site
Measure the roof surfaces and develop an accurate drawing, including
any obstacles such as chimneys and roof vents.
If plans are available, check to make sure that the plans match the final
structure.
Review the shading pattern across the roof surface from the residence itself,
from adjacent structures, and from other nearby features such as trees.
Identify any roof access areas or keep-out areas as required by the local
jurisdiction.
Confirm roof construction, type, and condition.
Assess roof rafter size, material, and spacing to confirm that the structure is
sound and can support the additional load of the array.
Identify any construction anomalies that may complicate the process of
locating rafters from the roof surface.
If you find structural problems such as termite damage or cracked rafters
that may compromise the structure’s integrity, consult a structural engineer.
Develop a Layout
Using the information collected in the site survey and from the span tables, complete a
system layout showing array location and distances from key roof features. Include
any information necessary for the permitting process.
Typically, PV modules are installed in portrait mode, with the long side of the
module running up the roof slope and the rails running horizontally across the roof
perpendicular to the roof rafters, which commonly run down slope.

Notes
- SnapNrack engineered systems should
only be used with SnapNrack components
and hardware. Any alternate application
may void the warranty and structural
calculations could become invalid.
Tips and Tricks
- Layout the entire array on the roof by
drawing all of the corners of the modules
on the roof with a roof marking crayon.
- Use a chalk line to help identify
the rest of the roof penetrations
- When leveling rails, hand tighten the
hardware to easily level and position
the rails. Once rails are level, fully
tighten hardware to specified torque.
Series 100 UL
Surveying and Layout
Arrays can also be installed in landscape mode, with the
modules oriented so that their long edge runs horizontally
across the roof and the rails run up the roof slope. Landscape
mode is typically used in cases where the roof has been
constructed with structural elements running horizontally
across the roof, but can also be used on standard residential
buildings for a variety of reasons including to facilitate a
convenient layout. When laying out the array, be sure to leave
space for the module clamps on the rails. Module mid clamps
are installed between modules in a row and require 0.5"
of space between the modules.
Adjustable end clamps require 1.5" of extra rail to extend
past the end of the module frame. If using the Universal End
Clamp, the rail is first cut flush to the module using the rail
cutting tool.
When installing multiple rows of modules, a minimum
spacing gap of 1/8" should be used between rows.
Submit array plans to local permitting jurisdiction and
proceed with the roof layout only when all permits for
the project have been granted by the authority having
jurisdiction.
Transfer the array layout to the roof using a roof marking
crayon to mark the inside and outside corners of the array.
Locate the estimated rafter positions and mark them in the
array area with a roof marking crayon.
Transfer rail and estimated attachment locations to the roof,
noting that attachments will be located at intersections of
rails and rafters. Layout rails such that module frame ends
do not overhang mounting rails by more than 25% of total
module length.

Notes
- SnapNrack engineered systems
should only be installed with SnapNrack
components and hardware. Any alternate
application may void the warranty,
the UL 270 Listing, and the structural
calculations may no longer be valid.
Step-by-Step Instructions
1) Use pry bar to remove roof tile
where the base will be installed.
Locate the rafter underneath the
decking of the roof by locating under
the eave, in the attic, or by tapping
the roof surface with a hammer.
2) Align the base over the rafter so
the hook can enter at the valley of
a tile and not extend beyond the
edge of the base. Drill two pilot
holes in the center of the rafter. If
the rafter is not found then seal the
pilot hole immediately with sealant.
) Apply roofing sealant to the bottom
of the base and directly onto each
lag screw. Attach the base with two
5/16” lag screws with washers at a
minimum 2 ½” lag shank embedment
into the rafter. Tighten the lag screw
to seat using a hand wrench.
4) Insert the top end of the arm into
the groove at the top of the base. The
arm will move freely in the base until
the channel nut is tightened. Position
the arm over the valley of the tile
below, then lower the arm down.
5) As you lower the arm you can
work the channel nut into the
lower groove of the base without
removing the channel nut.
6) Ensure the hook is aligned with
the valley of the tile. Tighten the bolt
in the channel nut and be sure the
arm fully seats to the base. The arm
will work in any position on the base
independent of the lag screw location.
7) If deck-level flashing is required,
integrate roof felt or a flexible flashing
with the existing underlayment
and over the Tile Hook.
8) Replace the roof tiles and
install SnapNrack Standard Rail
directly to the available channel
nut on the Tile Hook arm.

Notes
- SnapNrack recommends testing
underlayment surfaces for adhesion. If
adhesion is found to be marginal, then
a primer is recommended to ensure
optimal adhesion. Refer to flexible
flashing manufacturer’s technical
data for primer recommendations.
- SnapNrack recommends using
Protecto Wrap Protecto Seal
45 waterproofing membrane,
or equivalent, as the flexible
flashing and lap material.
Step-by-Step Instructions
1) Prepare the underlayment surface
for adhesion. The surface should be
dry, clean and free of any dirt, dust
or foreign matter that may prevent
adhesion. Clean the surface around the
Tile Hook with a brush of medium-sti
bristles. If necessary, prime the surface
with compatible spray or paint primer.
2) Peel o the backing from a
9-in. square of flexible flashing.
) Apply flexible flashing centered
laterally over tile hook and abutted
to the tile hook arm. Ensure tape
adheres to the corners between
the edges of the Tile Hook and the
underlayment as well as over the lag
screw heads and tile hook surface.
4) Press and smooth out any creases
or air bubbles with a roller to maximize
contact of the flashing adhesive to
100% of the surface and Tile Hook.
5) Peel o the backing from a 4-in.
by 1" strip of flexible flashing.
6) Apply the strip with 2" laps at the
top and side edges of the square
flashing. Roll out any creases or air
bubbles between the strip, the flashing
and the underlayment surface.

Step-by-Step Instructions
1) Locate the rafter underneath
the decking of the roof.
2) Drill a pilot hole through the roofing
material into the rafter to ensure that
the lag bolt will be located into a
solid portion of the rafter. If the rafter
is not found then seal the pilot hole
immediately with roofing sealant.
) Apply roofing sealant directly onto
the pilot hole and the hanger bolt
lag to ensure a water tight seal.
4) Attach the hanger bolt using the
threaded bit adapter with a minimum
embedment of 2 ½” lag shank into the
rafter. Tighten Lag bolt to seat.
5) Attach the channel nut of the
hanger bolt assembly into rail.
