Standing Seam Roof Snow Guard With Elongated Seam-Spanning Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing snow guards for standing seam metal roofs are inadequate in preventing large masses of snow from sliding off, as they either lack elongated support members or integrate them in a way that spans only a single roof segment, failing to effectively address the sliding issue.
Innovation Solution
A snow guard assembly comprising separate and distinct first and second snow support brackets with an elongated snow support member that is removably received in both brackets, extending upwardly to support snow and prevent sliding, while being secured to the standing seams without forming holes, and featuring adjustable and deformable designs for secure mounting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If small discrete snow supports are used located only over the standing seam, then the mounting is simplified, but the snow support coverage is insufficient and cannot prevent large masses of snow from sliding off
Solution Approach 1:
The patent combines multiple snow support functions into a single integrated elongated snow support member that spans across multiple standing seams. This member works in conjunction with brackets mounted on the standing seams to create a continuous snow retention barrier, thereby increasing coverage area while maintaining relatively simple installation procedures.
Solution Approach 2:
The invention transitions from point-based discrete snow supports to a linear elongated snow support member that extends across multiple roof segments. This dimensional change from zero-dimensional points to one-dimensional line provides continuous coverage along the roof slope, effectively increasing the snow support coverage area.
2Area of stationary object
If an elongated snow support member spanning multiple roof segments is used, then the snow support coverage is improved, but the device complexity increases due to separate brackets and assembly requirements
Solution Approach 1:
The snow guard system is divided into separate functional components: brackets that mount to the standing seams and an elongated snow support member that spans between them. This segmentation allows for independent optimization of each component and simplifies the overall assembly process, as the brackets can be pre-installed and the elongated member simply connected between them.
Solution Approach 2:
The brackets are designed with universal functionality to accommodate the elongated snow support member across different roof segments. The brackets serve dual purposes: providing structural mounting points and creating receptacles that receive the elongated member, thereby simplifying the overall assembly process despite the increased coverage area.
3Ease of manufacture
If holes are formed in the standing seam to mount brackets, then the mounting is simplified, but the roof integrity is compromised
Solution Approach 1:
The bracket acts as an intermediary component between the standing seam and the elongated snow support member. It provides a mounting interface that does not require penetrating the standing seam, thereby maintaining roof integrity while still enabling secure attachment of the snow guard system.
Solution Approach 2:
The invention extracts the mounting function from the standing seam itself by using separate brackets that attach to the standing seam without forming holes. This separation allows the standing seam to maintain its structural integrity while the brackets provide the necessary attachment points for the snow guard system.

AI summary
A snow guard assembly for a standing seam metal roof includes a first snow support bracket including a first bracket body secured to a first standing seam on the metal roof, and a second snow support bracket including a second bracket body secured to a second standing seam. The first and second snow support brackets are substantially aligned on the roof and removably receive an elongated snow support having a snow support surface extending upwardly relative to the panel of a roofing segment over which it is mounted such that the snow support surface will support snow accumulating on the standing seam metal roof and reduce its ability to slide off the standing seam metal roof.
