DECK MOUNT SNOW FENCE TECHNICAL GUIDE

TRA-Mage's Deck Mount Fences have been designed for use as a surface mounted snow fence for all pitched roofs, installed over ice and water protector membrane and sheathing, the lag bolts go through the sheathing into the rafters. For optimum assurance that your rafters can support the snow load, check with a structural engineer. You will need to know the snow load, roof slope and snow fence location. The general rule of the deck mount placement is to install one row of snow fences at the eave over the plate line, adding additional rows up the roof every 15' when the eave to ridge length runs over 20'. An engineer should be consulted to determine that each snow fence will hold specific load. For assurance that the lag bolts will not pull out due to snow and ice loads, check with the structural engineer or lag bolt manufacturer for load pull-out numbers on the lag size and length. The fail point on these snow fences is the lag screws and their pull-out poundage. Be sure that there are enough snow fences up the roof to carry the weight of the snow without pulling out the lag screws. Spacing brackets over 24" on center can cause the pipe to bend. Note: The snow load is based upon the ground snow load, roof slope and the number of square feet of snow load that will be on a given bracket. Check with your local building department to verify the snow loads for your area. It should be noted that snow fences are designed to stop upper-layered snow and ice from sliding off a roof. Snow brackets should be used to stop other snow and ice movement on roofs. Note: Snow fences do not stop ice dams from occurring. Please refer to the NTRMA and WSRCA manual for proper roofing application in heavy snow areas.

INSTALLATION

Install the snow fence over the roof plate line. The snow fence must be secured to the rafter. The hole size for the lag bolt is 1/2". So you will need to use a 3/8" bolt. TRA-Mage recommends caulking with butyl around the snow fence base in the lag holes. To keep the snow fences lined up with the holes for the pipes, run one pipe through the previous bracket installed to the new one. Snow fence brackets should be installed from 16" to 24" on centers. Slide pipes through the holes in the snow fence brackets. The pipes are 10' long. Install additional rows of snow fence up the roof as needed.
