SnoBar Standing Seam
SnoBar For Standing Seam Spacing Guidelines
In parts of the world that receive winter precipitation, snow and ice on glossy coated metal roofing can create an extremely dangerous avalanche condition. A properly installed snow guard system can mitigate this condition. Our approach to proper placement involves an overall spacing throughout the entire roof area to keep snow and ice from shifting initially. Once frozen precipitation loses its grip on a metal roof and begins a down-hill slide, everything in its path will be destroyed. A single row of guards placed along the eave or gutter edge of the roof is not always enough protection against this dangerous condition. An evenly distributed snow load will preserve the long-term integrity of the actual structure, metal roof and snow retention system. Isolating snow guards on partial roof sections such as just over doorways or roof vents is not recommended. Select your pitch below to get a general spacing guideline. All upper roof areas must have a snow retention installed before installing snow guards on a lower roof. This page should only be used only as a quick reference guide for estimating snow guard quantities and placement on roofs with up to 45 PSF ground snow load. Always consult with an architect or engineer for recommended snow guard placement for your project. This spacing guideline does not account for snow shadows, drifting or unseasonable conditions. If your ground snow load exceeds 45PSF please fill out our Quote Request Form for the heavy duty ColorBar systems.
| 1/12 Roof Pitch | 2/12 - 3/12 Pitch | 4/12 - 6/12 Pitch | 7/12 - 9/12 Pitch | 10/12 - 12/12 Pitch |
Panel: Valleys 12 to 24 inches.
IceStoppers: 12 inches to 17 inches
needs 1 IceStopper Per Panel - 18 inches to 24 inches needs 2 IceStoppers Per Panel
Pitch: 1/12
Spacing: Every 50 feet up the roof.
Isolated Roof Areas: Never use SnoBar in isolated roof areas such as just over doorways etc.
Snow load: Up to 45 PSF ground snow load.
Starting at 1 foot from the bottom edge, or over the end wall on a supported overhang, place the SnoBar using one clamp per seam, across the entire roof area. Go up the roof every 50 feet and run another row of SnoBar across the entire roof. Do not exceed 50 feet vertically between rows of bar. For Example: if your roof sheets are 100 feet long, your roof would require a row at approximately1 foot from the bottom and at 50 feet up from the bottom. When possible, always attempt to divide the roof areas into equal sections, with equal distance between rows, without exceeding the manufacturer maximum placement guidelines. All upper roof areas must have a snow retention installed before installing SnoBar on a lower roof. When possible, always attempt to divide the roof areas into equal sections, with equal distance between rows, without exceeding the manufacturer maximum placement guidelines. Never isolate areas of SnoBar such as just over doorways or vent pipes.

For Example: if your roof sheets are 36 feet long, your roof would require a row at approximately1 foot from the bottom and at 18 feet up from the bottom.

A 1" x 1" square, hollow tube made of Gator Shield-coated galvanized steel makes up the SnoBar system. The extruded 6061-T6 aluminum bar used in the ColorBar system can accommodate a color strip. Both systems are available, for online purchase, in mill finish or by phone in powder coated finish. The superior strength of the ColorBar allows it to span panels wider than 24".
Standing seam rail systems have an optional attachment called IceStoppers. These important accessories prevent low-lying snow and ice from sliding underneath the rails and are secured to the back of the bar without panel penetration. Although they are optional, IceStoppers are strongly advised over locations where there are pedestrians or vehicles present. Rail systems that have already been installed can be retrofitted with IceStoppers.
Almost any style of sloped roofing can be equipped with SnoBar and ColorBar devices. We offer snow rail systems for a variety of roofing types, including Standing Seam, Screw Down, PBR, Wavy Corrugated, Shingle, Membrane, TPO, and Slate.
On our website, you may order mill finish, 6-foot SnoBar, and ColorBar kits right away. We also have 12-foot bars that are shipped LTL in wooden crates when higher linear footage volumes are necessary or when a bespoke powder coated finish is wanted. Our technicians are ready to provide our customers with a price for these systems. Turnaround periods for price quotes are typically 24 to 48 hours.
In order to distribute weight evenly, a correctly designed snow rail system typically includes multiple rows up the roof slope. The layout of a project can be significantly impacted by variations in panel types, seam spacing, roof slopes, snow loads, and attachment methods. For more details, please refer to our spacing charts or fill out the SnoBar or ColorBar Quote Request Forms.
The SnoBar system features black plastic endcaps that seal the ends of the bars. The caps are made from Low Density Polyethylene with a service temperature of 150° F (66° C). These end caps provide the bar a clean, finished look while preventing outside elements, insects, and rodents from getting inside. 2 caps are required per bar and help to hide bare cut edges on painted or powder coated systems when field cuts are required.
