Adhesive Installation on Metal Panels
Installation Procedures for Adhesive Installation on Metal Panels
Area that Snow Guard will be installed must be clean from any surface contamination. Alcohol will clean the area and will dry quickly. Area must be dry for adhesive to bond.
Your first row; starting towards the eave above your exterior load bearing wall, place Snow Guards approx. 16” on Center side to side trying to maintain pattern in center of panel. Some installations due to the size of the overhang will require the snow guard to be placed lower than this suggests.
Add Snow Guards to areas over doorways, above pipes, chimney, and around valleys for added protection.
* If unsure of amount needed please contact Glacier Snow Guards, 866-766-9427.
Apply enough adhesive to entire bottom of Snow Guard (Approximately 5 Large Glacier Snow Guards per tube and 12 Mini Glacier Snow Guards per tube. Be sure to spread out adhesive evenly to assure that no air gaps will be concealed.
Press the Snow Guard firmly into place with the shingle ledge pointed up. Apply enough pressure so the adhesive comes out around perimeter.
Apply a small bead of adhesive around the perimeter of the Snow Guard to seal all edges. if the roof slope causes the snow guard to not stay in place while curing, apply a piece of tape to hold in place while curing.
Clean up any excess caulk with mineral spirits or alcohol.
Be sure to allow enough time for the adhesive to fully cure. The Surebond SB-190 requires 28 days of 50 degrees minimum for proper cure time.

Install screws with neoprene gasket washers through pilot holes of choice in Snow Guard and metal roof.
- A bead of sealant can me placed on the backside of the snow guard around the perimeter to seal.
- Screw must penetrate through structural support member under metal roof panel.
For most installations, two screws will be used in the Mini Glacier Snow Guard and 4 must be used with the large Glacier Snow Guard. Installer to determine proper length, size and number of screws necessary for required holding strength and torque.
Apply a small bead of adhesive around the perimeter of the Snow Guard to seal all edges.
Clean up any excess caulk with mineral spirits or alcohol.
Installation Procedures for Mechanical Installation on Metal Shingles with Snow Guard SHINGLE LEDGE Technology
Area that Snow Guard will be installed must be clean from any surface contamination.
Install the first Snow Guard no more than 12" from outside of exterior wall and 12" from outside of gable side. Determine the position of the shingle that will cover the shingle ledge by laying it in position and marking in the center of the lower shingle. From this mark, measure up no less than 1(one) inch and no more than 1 ¼(one and a quarter) inch and place a mark, this mark is the top of the Snow Guard.
The installer must determine the proper length, size and number of fasteners to use. The head of the fastener must be even with snow guard, if it sticks beyond the Snow Guard it could cause the fastener to push through the shingle.
Now is the time to install the first Snow Guard. Position the top of Snow Guard at the mark made in step 2. Insert fasteners into chosen holes of Shingle Ledge on uppermost part of Snow Guard. When fastening be sure that screws penetrate through a structural support member.
Install the remainder Snow Guards to this row following the guidelines discussed. There should be a maximum of 24" between each Snow Guard horizontally and a maximum of 24" vertically. Stagger the next row at the midpoint of the Snow Guards below. Continue this row until reach the other side of roof. Refer to the spacing chart for the amount of rows necessary.
Add Snow Guards to areas over doorways and around valleys for added protection.
