Sno-Safe Spacing Instructions
Start the first row of snow guards 36 inches from the Eave.
(Adjust this number lower to ensure at least 2 rows of snow guards can be installed)
Going up to the roof, space each row of snow guards by
Going up the roof, the amount of rows of snow guards required is:
Going across the roof, space each snow guard horizontally by
Each subsequent row should be staggered from the next.
Going across the roof, each row of snow guards would require:
