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 snow brackets or snow guards be placed upon the entire roof to keep all snow and ice from moving, at the very minimum these guidelines must be followed: 1. Never terminate the snow 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. 2. Snow brackets must be installed on both slopes of a valley. 3. 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. 4. Always install the snow brackets or snow guards per manufacturer details. The triangle end of the bracket is to be over the head lap of the metal tile. 5. Always install the snow brackets or snow guards on an upper roof that will shed snow and ice on a lower roof. 6. Always double the snow brackets on the eave course for heavier snow and ice loads.
