Metal roofing is an ideal choice for snow-prone regions thanks to its durability, longevity and ability to withstand harsh weather conditions. But its smooth, slippery surface can also create a unique challenge: rooftop avalanches that can release large amounts of snow and ice without warning, putting people and property below at risk.

Proper snow retention is about more than simply placing snow guards on a roof. Effective rooftop snow management requires an understanding of how snow behaves, how loads are transferred through the system and how roof type, slope, snow load, attachment method and system layout all work together.

This course will take you from the fundamentals of metal roofing and the science behind rooftop avalanches to understanding the different types of snow retention systems and attachment methods available. You’ll learn the differences between mechanically attached and chemically attached solutions, continuous and unitized systems, and how tested, engineered attachment methods can help preserve the integrity of the metal roof.

From there, we’ll explore how to select, design and lay out a snow retention system for a specific project. You’ll learn how factors such as roof snow load, slope, roof dimensions, panel type and substrate influence system design, and how manufacturer-provided calculators can turn those project-specific inputs into an engineered layout based on tested performance data.

We’ll also cover factor of safety, coordinating snow retention with rooftop solar, real-world examples of different snow guard installations and the importance of selecting tested and certified products backed by meaningful warranties.

By the end of this course, you’ll be better prepared to evaluate metal roof conditions, select appropriate snow retention solutions and design, specify and install systems for long-lasting performance. Whether you’re a roofing contractor, installer, building owner, structural engineer, architect, specifier or simply looking to deepen your understanding of snow and metal roofing, this course will give you the knowledge and resources to approach rooftop snow management The Right Way!®
