Screw Down

Our test results show that pad-style snow guards made of metal and polycarbonate perform similarly. To view the results of our tests, please visit the resources page. For our customers, aesthetics frequently matter just as much, if not more than strength when making a decision.

The majority of our polycarbonate pad-style snow guards come with molded starter points. Our self-tapping screws can easily drill through this material. These guards can, however, be pre-drilled if you'd like, but it's not required. Pre-drilled holes are included in the aluminum SnoCleat PBR and SnoCleat 2.67 as well as the Snojax 1 and Stainless SnowCatchers.

With a single tube of Novaflex MR150 sealant and screws, about 10 of our large polycarbonate snow guards and 20–25 of our smaller ones can be installed. Be aware that this may vary depending on the user's application. The Novaflex MR150 is not an adhesive but a sealant. It cannot be used in place of Surebond SB-190 to glue down polycarbonate snow guards.

The majority of our screw-down snow guards can be installed using one of the two screws that we currently offer. The Master Gripper is a 2" long #14 self-tapping screw used for wooden applications. The Master Driller is a 1.5" long #14 self-tapping screw for use with metal applications. Both of these fasteners have neoprene washers, are silver in color, and are made of case-hardened carbon steel. The SnoCleat 2.67 and 2.67 snow rail systems utilize 3" screws because their brackets straddle the panel's high ribs. Longer screws can be required, depending on whether or not there is insulation under the panels.

Penetration of a standing seam metal panel is never recommended. Due to the panel’s floating nature, screwing through a standing seam metal roof can compromise its waterproof integrity, potentially leading to leaks and rust. It also may void manufacturer warranties due to improper installation.
