Product Data Sheet
FLEX SNOWGUARD PVC COATED
AVALANCHE PREVENTION SYSTEM
Flex SnowGuards are designed to retain snow and ice on pitched single ply roof systems. SnowGuards
are constructed of .125 thick aluminum and are available in 4’ lengths. The four-foot SnowGuard
sections are installed in two staggered rows with 3’ spacing between them across the roof surface. This
spacing provides continuous protection since each SnowGuard overlaps with the SnowGuard above or
below it while also distributing the snow load.

1. Install two rows of 4’ length SnowGuards along the perimeter of the roof. The two rows

the roof for placement. Chalk a second line 3’ up from the first line.

across the roof with three-foot spacing between each guard (same as first row).

Pounds Per Lineal Foot. Follow Factory Mutual Loss Prevention Data Sheet 1-49 for
