Rocky Guards are very durable metal snow guards for roof snow retention.

The Rocky Guard RG-Slate is 16" in overall length with a "barb" at the end.   The snow guard installs by sliding the "barb" end underneath the existing, overlapping roof tile from the course above. The snow guard latches to the top edge of the lower roof tile piece.  There are no screws or bolts used to install this style of snow guard. 

Designed for retro-fit installations on natural slate and thin concrete tile roofs.
