Panelized Roofing Connectors for Waterproof Panel Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a roofing system that is simple to install, securely attaches roofing panels to rafters and adjacent panels, while allowing for easy disassembly of panels for replacement without compromising the waterproof integrity of the roof assembly.
Innovation Solution
The roofing system employs connectors with T or I shapes, secured to rafters and roofing panels, which create a waterproof seal through overlapping portions and sealants, allowing for the secure assembly and disassembly of roofing panels while maintaining a watertight interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional roofing systems are used, then the roof structure is stable and secure, but the installation process is complex and time-consuming
Solution Approach 1:
The roofing system is divided into modular panels with standardized connectors. Each panel is a self-contained unit that can be independently installed, allowing workers to assemble the roof systematically rather than handling large continuous sections. The connectors themselves are segmented into male and female components that interlock in standardized sequences.
Solution Approach 2:
The connector design provides multiple functions within a single component: securing panels to rafters, interlocking adjacent panels, providing waterproof sealing, and enabling easy disassembly for panel replacement. This multi-functionality reduces the number of different components needed and simplifies the overall installation process.
2Reliability
If roofing panels are securely attached to ensure waterproof integrity, then the roof is watertight, but disassembly for panel replacement becomes difficult
Solution Approach 1:
The connector system transitions from a permanently fixed state to a dynamically reversible state. Fasteners are designed to be securely engaged during normal operation but can be easily disengaged when panel replacement is needed. The mechanical interlocking features provide stable connection under load but allow controlled disassembly through simple operational actions.
Solution Approach 2:
The connector acts as an intermediary component between the roofing panel and the roof structure. It provides the waterproof sealing function while simultaneously serving as the detachment point for panel removal. By concentrating both the sealing and attachment functions in the removable connector rather than in permanent structural elements, the system enables easy panel replacement while maintaining waterproof integrity during service.
3Strength
If multiple connectors are used to secure panels to rafters and adjacent panels, then the attachment is secure, but the number of components and installation steps increases
Solution Approach 1:
The connector design merges multiple attachment functions into single integrated components. A single connector simultaneously secures a panel to the rafter structure and interlocks with adjacent panels, eliminating the need for separate fasteners for each function. The flange and projection elements are combined in unified structural pieces rather than separate components.
Solution Approach 2:
Each connector is designed as a universal component that performs multiple attachment tasks: securing panels to rafters, connecting adjacent panels laterally, providing waterproof sealing, and enabling easy disassembly. This multi-functionality reduces the variety of different connector types needed and simplifies inventory and installation procedures.

AI summary
A roofing system including a plurality of roofing panels that can be releasably secured to rafters or other supports of the roof by connectors. In embodiments, the connectors can include first and second connectors, each of which can include a plate with a projection extending therefrom, and with the plates defining flanges on each side of the projection. The plates of the first and second connectors are configured to seat on and at least partially extend along one of the rafters of the roof structure and along exterior facing surfaces of adjacent ones of the roofing panels to releasably secure the roofing panels to the rafters.
