Pipe Detail
Step 1
Cut on the proper pipe diameter
marked on the flashing.
Step 2
Position over pipe and slide
down the pipe.
Step 3
Apply polyurethane sealant
to the bottom of the base.
Step 4
Mold the flexible base to
the panel contours.
Step 5
Fasten with 1/4” x 1-1/8” drilling
fastener every 1-1/2” around
the base.

Tools and Rules:
Basic Equipment Required:
Tie-off ropes, safety harness, long level, ladders, scaffolding with
approved planking, extension cords with approved ground plugs
and services.
Additional Tools:
Metal folding tool, hammer, chalk line, measuring tape, metal cutting
tools - nibblers, drills, hacksaw, utility knife, pop-rivet gun, caulking
guns, layout and combination square, C clamps, sheet metal shears
(including RH, LH, straight and overhand). Power driven screw gun
with proper bits, depth-setting nosepiece, variable speed.
Choose the correct equipment and tools to do the job in a safe
manner. Wear safety gear and follow OHSA requirements.
Follow of few simple rules:
1. Never cut the panels with an abrasive cut-off wheel or torch, as this will
damage the finish.
2. Do not weld the trim or panels.
3. Remove any small burrs left by cutting, screwing or drilling.
4. Remove protective masking immediately after trim is installed.
5. Caution should be taken when unloading the panels to prevent damage.
6. Use appropriate screws for the type of underlayment and long enough to
fully penetrate and secure the panel.
7. The stored materials should be kept dry.
8. Do not cut on finished roof. Remove all drill spirals, chips and
dust immediately.
9. Seal neoprene closures and soft cell foam by applying appropriate
sealant to both surfaces.
10. Put appropriate sealant/butyl tape between overlapping trims.
11. Overlap trims in a manner not to impede the flow of water.

Sidewall Detail
1. Install metal panel up to within
1” of the sidewall.
2. Fasten “Z” closure in bed of
butyl sealant at top of panel
as shown.
3. Fasten sidewall trim over
“Z” closure to face of sidewall.
4. Apply counterflashing over
the sidewall trim, and seal
into reglet.
NOTE: Trims should be fastened
to substrate and sidewall using a
#12 x 1” wafer head screw.
Note Regarding Trim Details
The applicaiton of flashing and trim requires a detailed approach. Consideration should be given to the roof’s geometry and course it
creates for water run-off. Location of gutters and the use of snow retention systems should also be considered. Proper planning
regarding the sequence of material overlap is critical. Sealants, such as butyl tapes and tripolymers, should be used at overlapping
trim edges, in conjunction with exposed fasteners, and to seal flashings. All fasteners should be properly tightened and not overdriven
at an angle. Fasteners that are too loose can “back out” over time. An overdriven fastener may cause a depression in the material,
which becomes a collection point for standing water.
