Types of roof snow guards that we manufacture

AceClamp offers precision-engineered fixed bar or rail type snow retention systems for almost any roof. Customers with metal roofs enjoy the convenience and leak protection of our clamp-on, non-penetrating clamps.  For customers with slate and asphalt shingle roofs, we offer a very effective screw-down bar type snow guard system that is available in single, two, three, and four-bar configurations.  For customers with low-slope membrane roofs, we offer a snow rail system that utilizes a screw-down plate that is sealed by a heat-welded power-grip pad.

Non-Penetrating Clamp-on Snow Guards for SSMR

Roofing Material Types:  Metal (SSMR)

We have several snow guard options available for customers with standing seam metal roofs, and no matter which system you choose, you're sure to enjoy our non-penetrating, pre-assembled sliding pin clamps.  AceClamp® metal roof snow retention systems install in about half of the time of competitive systems, helping roofers to be more profitable on installation projects by eliminating pre-assembly tasks and retorquing.  Securing our clamps to seams is done with just a single fastener, and installation can be completed with just a single tool.

How do I spec my snow guard system?

We are here to help!  Just answer a few questions on our rapid-quote project survey, and our roofing specialists will give you a suggested layout and plan for your system.  Our team will study any engineering diagrams, specs, and photos that you provide to design the right snow retention system for your roof. (not required but helpful)  While we're at work, there are a few aesthetic and functional choices for you to consider, such as whether you'd prefer a powder coat or natural metal finishes, or whether you'd prefer snow bars or snow rails.
