Spacing For SnoCleat RC/RCT on Standing Seam Metal Roofs

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 downhill 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 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 SnoBar/ColorBar systems.

1/2 - 2/12 Pitch 3/12 - 4/12 Pitch 5/12 - 6-12 Pitch 7-12 - 12-12 Pitch

 

1/2 - 2/12 Roof Pitch

Layout


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 feet 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 feet 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's maximum placement guidelines. Please see the drawing above for general placement guidelines. All upper roof areas must have 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's maximum placement guidelines. Never isolate areas of snow guards such as just over doorways or vent pipes. 

3/12 - 4/12 Roof Pitch

Layout


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 feet 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 feet 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's maximum placement guidelines.

5/12 - 6/12 Roof Pitch

Layout


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 feet 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 feet 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's maximum placement guidelines.

7/12 - 12/12 Roof Pitch

 

Layout

 
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 feet 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 feet 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's maximum placement guidelines.
