TRA-Mage - Snow Bracket or Snow Guard J Installation Guide

At TRA-Mage, our snow brackets or snow guards 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 or snow guards 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.

Snow Bracket J Installation Guide

Although we strongly recommend that TRA-Mage Snow Brackets be placed upon the entire roof to keep all snow and ice from moving, at the very minimum these guidelines must be followed:

Never terminate the brackets in a straight vertical line up the roof. They must be installed from the eave to ridge going out at a 45 degree angle up the roof.
Valleys must have snow brackets or snow guards on both slopes.
If you are only installing snow brackets or snow guards on one side of the roof, check with your engineer to see if your truss or stick frame construction can take the entire load on one side of the roof structure.
Always install the snow brackets per manufacturer details. The triangle of the snow bracket is to be over the head lap of the shingle.
Always install the snow brackets on an upper roof that will shed snow and ice on to a lower roof.
Always double the snow brackets or snow guards on the eave course for heavier snow and ice loads.
