IceStoppers are an add-on product for the popular SnoBar and ColorBar metal
roof snow rail retention systems. They have a 90-degree foot on the bottom that
keeps them from bending under the bar. The two self-drilling tek screws
(not included) mechanically mount the IceStopper to the bar which keeps it from
flipping up over the bar like other systems. It is important to use
IceStoppers, especially over pedestrian walkways and parking areas, where it is
imperative to keep snow and ice from coming off of the roof. This product will
not prevent icicles from forming on the eave edge of your roof. We would
recommend a heat tape system for dealing with that situation, if necessary.
On standing seam panels that are 12” to 16” wide, one IceStopper is recommended.
On 18” to 24” panels we recommend two IceStoppers equally spaced apart in the
panel flat. These can be used on wider panels such as the 36” and 42” insulated
panels. The wider panels require at least 3 IceStoppers equally spaced across
the valley. To pick the size that is right for your roof, measure from the
panel flat to the top of the bar. Order the IceStopper size that is closest to
this measurement. It is common for the IceStopper to sometimes protrude above
the bar slightly, this is more noticeable when oil canning in the panel is present
but will not negatively impact the performance of the IceStopper. When
installing, a small 1/8” gap may be left between the foot of the IceStopper and
the panel. A larger gap is not recommended.
