SnoCleat Standing Seam Mounted Snow Guards Spacing
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 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 45PSF please fill out our Quote Request Form for the heavy duty SnoBar/ColorBar systems.
Please Click on Your Roof Pitch Below
1/2 - 2/12 Roof Pitch
Pitch: 1/2/12 to 2/12 pitch.
Use: 1 snow guard per seam every 15 feet up the roof.
Snow load: Up to 45 PSF ground snow load.
Starting at 1 and 2 foot from the bottom edge, place a snow guard on each panel seam in a staggered pattern, across the entire roof area. Go up the roof 15 feet and repeat the staggered pattern on each panel seam. Do not exceed 15 feet vertically between rows of guards. For Example: if your roof sheets are 30 feet long, your roof would require a stagger pattern at 1 and 2 foot from the eave and a second staggered pattern at 14 and 15 feet from the eave line. When possible, always attempt to divide the roof areas into equal sections, with equal distance between rows, without exceeding the manufacturer maximum placement guidelines. Please see drawing above for general placement guidelines. All upper roof areas must have a snow retention installed before installing snow guards 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 snow guards such as just over doorways or vent pipes.
3/12 - 4/12 Roof Pitch
Pitch: 3/12 up to 4/12 pitch.
Use: 1 snow guard per seam every 10 feet up the roof.
Snow load: Up to 45 PSF ground snow load.
Starting at 1 and 2 foot from the bottom edge, place a snow guard on each panel seam in a staggered pattern, across the entire roof area. Go up the roof 10 feet and repeat the staggered pattern of guards on each panel seam. Do not exceed 10 feet vertically between rows of guards. For Example: if your roof sheets are 20 feet long, your roof would require a staggered pattern at 1 and 2 foot from the eave and a second staggered pattern at 9 and 10 feet up from the eave. When possible, always attempt to divide the roof areas into equal sections, with equal distance between rows, without exceeding the manufacturer maximum placement guidelines. Please see drawing above for general placement guidelines. All upper roof areas must have a snow retention installed before installing snow guards 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 snow guards such as just over doorways or vent pipes.
5/12 - 6/12 Roof Pitch
Pitch: 5/12 up to 6/12 pitch .
Use: 1 snow guard per seam every 8 feet up the roof.
Snow load: Up to 45 PSF ground snow load.
Starting at 1 and 2 foot from the bottom edge, place a snow guard on each panel seam in a staggered pattern, across the entire roof area. Go up the roof 8 feet and repeat the staggered pattern of guards on each panel seam. Do not exceed 8 feet vertically between rows of guards. For Example: if your roof sheets are 16 feet long, your roof would require a staggered pattern at 1 and 2 foot from the eave and a second staggered pattern at 7 and 8 feet up from the eave. When possible, always attempt to divide the roof areas into equal sections, with equal distance between rows, without exceeding the manufacturer maximum placement guidelines. Please see drawing above for general placement guidelines. All upper roof areas must have a snow retention installed before installing snow guards 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 snow guards such as just over doorways or vent pipes.
7/12 - 12/12 Roof Pitch
Pitch: 7/12 up to 12/12 pitch .
Use: 1 snow guard per seam every 5 feet up the roof.
Snow load: Up to 45 PSF ground snow load.
Starting at 1 and 2 foot from the bottom edge, place a snow guard on each panel seam in a staggered pattern, across the entire roof area. Go up the roof 5 feet and repeat the staggered pattern of guards on each panel seam. Do not exceed 5 feet vertically between rows of guards. For Example: if your roof sheets are 10 feet long, your roof would require a staggered pattern at 1 and 2 foot from the eave and a second staggered pattern at 4 and 5 feet up from the eave. When possible, always attempt to divide the roof areas into equal sections, with equal distance between rows, without exceeding the manufacturer maximum placement guidelines. Please see drawing above for general placement guidelines. All upper roof areas must have a snow retention installed before installing snow guards 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.
