ADDITIONAL INFORMATION:
Custom-Built Standing Seam
Roof Panels are
roll-formed at the job
site after framing is
completes to insure proper
length and correct panel
coverage. Generally
the panels are immediately
placed on the roof, thus
reducing the chance of
damage to the panels to a
minimum. This can
save four to six weeks of
construction time,
compared to conventional
metal roofing that must be
field measured, roll
formed at a factory,
shipped to the jobsite,
and then loaded onto the
roof.
Custom-Built panels are
then secured to the roof
purlins or decking by
concealed anchor clips.
This virtually eliminates
penetration of the roof
panel by fasteners to the
structure. Thus
holes which tend to
elongate with thermal
movement and cause leaks,
are reduced to a minimum.
Anchor clips are designed
to allow thermal movement,
permitting use of longer
panel lengths than
conventional metal roofing
systems. Custom
Built panels are formed
ridge-to-eave in full
lengths. This
provides for clean
unbroken lines and
eliminates end-lap leaks.
Custom Built panels,
clips, and ridge closures
can be designed into a
weathertight system for
roofing and siding in both
new construction and
re-roofing.
Companion items such as
gutters; drip angles;
fascias; ridge caps,
window, or gable trim; and
other flashings are not
standard, but are
fabricated to suit job
conditions.
The 1-1/2" standing
seams between panels are
rolled closed over anchor
clips, in the field, by an
electronically driven
self-propelled seamer.
The first profile has
proven by far the most
popular method of seaming
as the panel ends up
appearing as though it has
small batten strips
attached. It is
recommended to use the
second profile when
installing roofs where
slopes will be under a one
in twelve pitch. Use
of sealant tape permits
use of first profile on
slopes lower than one in
twelve pitch.
Every custom built roof
panel is attached to the
roof using custom built
concealed anchor clips.
Clip selection, placement,
and method of attachment
are determined by thermal
movement, uplift loads,
and the building
structure. The
custom built slider type
anchor clips are designed
to permit longitudinal
thermal movement while
securing panels to the
structure. The
custom built stationary
anchor clips are used only
when there is little or no
thermal movement, for
lengths under 30 feet.
