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 the roof, space each row of snow guards by

20 inches

Going up the roof, the amount of rows of snow guards required is:

13 rows

Going across the roof, space each snow guard horizontally by

24 inches

Each subsequent row should be staggered from the next.

Going across the roof, each row of snow guards would require:
