ColorBar Seam-Mounted Snow Rails Spacing Layout Guide
In areas with high winter precipitation, the accumulation of snow and ice on shiny painted metal roofs can create very dangerous avalanche conditions. A properly installed snow retention system can mitigate this condition. Our approach to proper placement includes full patterns of snow guards across the entire roof surface to prevent snow and ice from moving in the first place. When frozen precipitation loses its footing on the metal roof and begins to slide down the slope, it destroys anything in its path. Snow guards just placed along the edges of eaves do not always adequately protect against this dangerous condition. The even distribution of snow loads ensures the long-term integrity of the structure itself, the metal roof, and the snow retention system. Snow guards installed on partial roof sections, such as just over doorways or roof stacks, are not recommended. Select a pitch below for a general guideline. Snow guards must be installed on all upper roof surfaces before they are attached to a lower roof. Use this page only as a quick reference guide for estimating the amount and placement of snow retention devices on roofs with ground snow loads up to 45 PSF. Always consult an architect or engineer for recommended snow guard placement for your project. This snow retention placement guideline does not take into account snow shadows, snowdrifts, or unusual conditions.. If your ground snow load exceeds 45 PSF, please fill out our Quote Request Form for the heavy duty SnoBar/ColorBar systems.
Choose Your Roof Pitch
1/12 to 2/12 Roof 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 to 2/12
Isolated Roof Areas: Never use ColorBar in isolated roof areas such as just over doorways etc. Snow load: Up to 45 PSF ground snow load.
Spacing: Every 40 feet up the roof.
Starting at 1 foot from the bottom edge, or over the end wall on a supported overhang, place the ColorBar using one clamp per seam, across the entire roof area. Go up the roof every 40 feet and run another row of ColorBar across the entire roof. Do not exceed 40 feet vertically between rows of bar. For Example: if your roof sheets are 80 feet long, your roof would require a row at approximately1 foot from the bottom and at 40 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's 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.
3/12 - 6/12 Roof 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: 3/12 to 6/12
Isolated Roof Areas: Never use ColorBar in isolated roof areas such as just over doorways etc.
Snow load: Up to 45 PSF ground snow load.
Spacing: Every 15 feet up the roof.
Starting at 1 foot from the bottom edge, or over the end wall on a supported overhang, place the ColorBar using one clamp per seam, across the entire roof area. Go up the roof every 15 feet and run another row of ColorBar across the entire roof. Do not exceed 15 feet vertically between rows of bar. For Example: if your roof sheets are 30 feet long, your roof would require a row at approximately1 foot from the bottom and at 15 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's 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.
7/12 - 12/12 Roof 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: 7/12 to 12/12.
Isolated Roof Areas: Never use ColorBar in isolated roof areas such as just over doorways etc.
Snow load: Up to 45 PSF ground snow load.
Spacing: Every 10 feet up the roof.
Starting at 1 foot from the bottom edge, or over the end wall on a supported overhang, place the ColorBar using one clamp per seam, across the entire roof area. Go up the roof every 10 feet and run another row of ColorBar across the entire roof. Do not exceed 10 feet vertically between rows of bar. For Example: if your roof sheets are 20 feet long, your roof would require a row at approximately1 foot from the bottom and at 10 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's 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.Disclaimer
