Roof Edge Bracket With Vertical Flange For Insulation Clearance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing roof edge mounting systems struggle to securely attach roof trim to buildings with multiple layers of insulation, particularly over pre-cast concrete walls, as the standard wood nailer attachment height is insufficient, and traditional solutions fail to accommodate damaged nailers or varied insulation configurations.
Innovation Solution
A roof edge mounting bracket with a base member and vertical attachment flange, allowing for adjustable height and angle configurations, including a cantilevered design for clearance, fabricated from aluminum extrusion with staggered fastener openings, enabling secure attachment to various substrates like pre-cast concrete, concrete blocks, and insulation-filled metal studs, using longer fasteners if necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple layers of insulation are added to increase insulation efficiency, then thermal performance is improved, but the attachment height of roof trim becomes too low relative to the building top
Solution Approach 1:
The patent introduces a mounting bracket as an intermediary component between the nailer and the roof trim. This bracket includes a base member that attaches to the nailer and a vertical attachment flange that extends upward to provide a new attachment surface for the roof trim, effectively decoupling the trim attachment height from the insulation layer thickness.
Solution Approach 2:
The solution transitions from a horizontal attachment configuration (direct attachment to nailer) to a vertical extension configuration. The vertical attachment flange creates a new dimension for attachment, allowing the roof trim to be positioned at the correct height while accommodating thick insulation layers.
2Ease of manufacture
If wood nailer is used for mounting roof trim, then traditional installation is simplified, but the nailer may rot and become unsuitable for attachment
Solution Approach 1:
The mounting system is segmented into distinct functional components: the base member that interfaces with the nailer, the vertical attachment flange that provides the mounting surface, and the fastening mechanism. This segmentation allows the bracket to adapt to different nailer conditions and materials.
Solution Approach 2:
The bracket design allows for parameter changes in fastener length and type to accommodate different substrate conditions. Longer fasteners can be used when the nailer is damaged or when attaching directly to deeper substrates like pre-cast concrete or concrete blocks.
3Ease of operation
If roof trim is attached directly to nailer, then attachment process is simple, but the lower portion of roof trim cannot be reasonably secured when insulation is extended
Solution Approach 1:
The mounting bracket is designed as a universal component that can be used with various nailer types (wood, non-wood), different insulation configurations (single layer, multiple layers, extended insulation), and various substrate materials (pre-cast concrete, concrete blocks, metal studs). This multi-functionality maintains ease of operation while greatly increasing adaptability.

AI summary
A roof edge mounting bracket preferably includes a base member and a vertical attachment flange. The base member extends outward in a horizontal orientation from the vertical attachment flange. A lower portion of the vertical attachment flange extends below the base member and an upper portion of the vertical attachment flange extends above the base member. A plurality of staggered fastener openings are preferably formed through the base member. An angled roof edge bracket includes a base member and a vertical attachment flange. The base member extends from the vertical attachment flange at an acute angle. A cantilevered roof edge bracket preferably includes a cantilevered base member and a vertical attachment flange. A roof edge angle bracket includes a base member and a vertical attachment flange. A roof edge vertical bracket preferably includes a vertical attachment flange, a bottom offset lip and an upper retaining lip.
