Coated Bracket Mounting for Membrane Roof Leak Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing snow barricade systems for membrane roofs fail to maintain a leak-proof seal, leading to water seepage and invalidation of roofing warranties due to the lack of sealing between the membrane patch and the base plate.
Innovation Solution
A snow barricade mounting system where a bracket coated with material corresponding to the membrane layer material is secured to the wood decking, allowing a membrane patch to be welded to both the bracket and the membrane layer, creating a complete seal around the perimeter of the base plate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a bracket is mounted directly to wood decking with a membrane patch placed over it, then the barricade can be secured to the roof, but water can seep under the patch through the patch notch, compromising the leak-proof seal
Solution Approach 1:
A coating material is introduced as an intermediary between the bracket base plate and the membrane patch. This coating material is compatible with both the bracket and the membrane patch materials, enabling the membrane patch to be hot-air welded directly to the bracket surface, creating a seamless waterproof connection that eliminates water seepage paths
Solution Approach 2:
The surface properties of the bracket base plate are changed by applying a coating material that matches the membrane patch material composition. This parameter change in surface compatibility enables direct hot-air welding between the bracket and membrane patch, transforming the interface from a non-weldable metal surface to a weldable membrane-compatible surface
2Ease of manufacture
If existing mounting systems are used, then installation is simple, but the roofing manufacturer's warranty is invalidated due to exposed leakage paths
Solution Approach 1:
The bracket base plate is pre-coated with the appropriate material before installation. This preliminary action ensures that the waterproofing capability is built into the mounting component itself, eliminating the need for complex post-installation sealing procedures while ensuring warranty compliance through a factory-applied, reliable coating
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution ensures a watertight seal, preventing water leakage and maintaining the integrity of the membrane roof, thus ensuring compliance with roofing warranties.
Implementation Method 1
Membrane patch is then hot-air welded to the coated base plate and the membrane layer around the perimeter of the base plate

AI summary
A snow barricade mounting system for use with a membrane roof system is provided. The system includes a bracket having a base plate and an upstanding arm, and a means for securing the bracket to membrane roof. The system further comprises a membrane patch comprised of a material corresponding to the membrane layer. In one embodiment, bracket is coated with a material corresponding to the membrane layer and the membrane patch, such that when membrane patch is secured a complete seal between both the membrane patch and the base plate, and between the membrane patch and the membrane layer, is achieved. In an alternative embodiment, a sheet of material corresponding to the membrane layer material is secured to the top side of the base plate. A method of securing a snow barricade mounting system to a membrane roof system is also provided.
