Snow Guard Layout Pattern Guide for Slate, Shake and Shingle Roofs

Rocky Mountain Snow Guard Layout Pattern Guide for Slate, Shake and Shingle Roofs

For Slate, Shate, Asphalt Shingle, Metal Shingle and Synthetic Slate and Shake Roofs

Instruction Steps:

1)

The 3-row pattern at the eave is the minimum requirement for all roofs.

Rows are staggered and spaced approximately 12” apart depending on course spacing of roofing material. ST Series Snow Guards are placed 24” O/C

within rows.

2)

Additional rows of ST Series Snow Guards may be necessary to stabilize the snow in some conditions:

  • On longer roof decks
  • Steeper roofs
  • Slippery roof surfaces such as slate, synthetic products and metal
  • On roofs in heavy snow load areas

Contact Rocky Mountain Snow Guards for a recommended ST Series Snow Guard layout if any of these factors are present.
