At
TRA-Mage, our snow brackets are engineered from the fail point
of the roof system. Through proper testing and research, we
have developed unique engineered charts. These charts calculate
the number of snow brackets required and their correct distribution
as provided in a roofing square layout based on the roof surface
type, sheathing type and thickness, snow load, and roof slope.

Bracket G Technical Guide
Tile
Roof Accessories (TRA-Mage) Snow bracket G has been engineered
for use with all flat seam metal roofs, wood shakes, slate, and
Monier Lifetile Cedarlite concrete tile where retrofit is required
and fasteners cannot be exposed.
For optimum assurance that snow and ice will not slide, always
use the snow load /slope chart to determine the number of snow
brackets per roofing square. Snow loads vary. Check with the local
building department to verify the snow load for your area.
INSTALLATION
