This page is a General Layout for adhesive style snow guards. For roofs with less than 45 PSF ground snow load, it should only be used as a quick reference for determining snow guard quantities and positioning.
Panel Type: For panels with Less than 16 inches in valley width.
Roof Pitch: Between 1/12 and 2/12.
Configuration: One snow guard for each panel flat, spaced one foot apart
Snow guard spacing: Calls for a staggered row of guards every fifteen feet as you ascend the roof.
Snow Load: Maximum ground snow load of 45 PSF.
Across the entire roof area, stagger the placement of snow guards by placing one and two feet from the bottom edge in the center of each valley. Continue the staggered pattern of guards at a height of fourteen and fifteen feet, following the same pattern as below. Between guard rows, do not extend more than fifteen feet vertically. For instance, your roof would need a row at 1 and 2 feet from the bottom and at 14 and 15 feet up from the bottom if your roof is 30 feet long.
- Before installing snow guards on a lower roof, all upper roof areas need to have snow retention installed.
- Always try to divide the roof areas into equal sections when possible, keeping the distance between rows equal, while staying within the maximum placement guidelines specified by the manufacturer.
