Remember to follow Alpine’s snow guard layout recommendations to achieve the best performance.

Performance Data Facilitates Better Solutions

Alpine has been designing, engineering and manufacturing snow guards since 1993. In that time, we have established snow guard layout recommendations based upon roofing experience, snow guard design and testing. Alpine’s ongoing collection of performance data facilitates better solutions and layout suggestions.

Standard Pad-Style Layouts Options & Estimated Quantities

Alpine’s recommended layouts are based on structural testing of our pad-style snow guards combined with our company founder’s nearly 40 years of experience in roofing.

  • All layouts begin with a 3-row pattern

A Quick Word About Pad and Pipe-Style Difference

Both styles are intended to hold a snow mass and allow it to shed gradually. Pad-styles add friction to allow snow to release in small chunks, pipe-styles act as barricades to hold snow until it sheds as meltwater.

Assess a roof for snow management system design

Roofs shed snow in valleys and at the eaves increasing the need for additional snow management in lower areas. Roofing design considerations: egress points, architectural elements, potential for property damage and:

  • Eave & rafter length
  • Roof pitch
  • Roof material
  • Ground snow load
  • Dormers, upper roofs, mechanicals and more

Recommended snow guard layout design

  • Snow guards should be concentrated along the eave
  • Upper roofs, dormers and rooftop architectural elements will impact snow guard layout
  • On roofs with greater rafter length, steeper pitches, higher ground snow loads, additional snow management devices are needed higher up the roof
