Flashing Panel With Offset Portion for Tiled Roof Interruption Fit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flashing elements for tiled roofs do not provide a close fit to the tiles near installed brackets, are difficult to install, and can lead to increased water penetration, compromising roof integrity.
Innovation Solution
A flashing panel with a firm structure, comprising a panel base and an offset portion, is designed to fit into the interruption created by removing a tile, ensuring it lies closer to the lower tile layer, with a hook arrangement to secure it in place without adhesives or fixings, and optionally matching the tile curvature for a snug fit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional flashing elements are used to cover interruptions in tiled roofs, then installation is possible, but they do not provide a close fit to the tiles and allow increased water penetration
Solution Approach 1:
The flashing panel is divided into multiple sections: a first base section, a second base section, and an offset portion connecting them. This segmentation allows each part to fit precisely into the interruption space and against different tile surfaces, achieving a close fit that conventional single-piece flashing elements cannot provide
Solution Approach 2:
The offset portion extends away from the panel base in a direction perpendicular to the main plane of the tiles, creating a three-dimensional configuration. This dimensional change allows the flashing panel to accommodate the bracket installation while maintaining contact with the tile surfaces, ensuring water tightness without compromising the close fit
2Productivity
If conventional flashing elements are used, then coverage is provided, but they are difficult and time consuming to install
Solution Approach 1:
The flashing panel is pre-formed with the specific geometry including the offset portion and base sections during manufacturing. This preliminary action eliminates the need for on-site cutting, shaping, or complex assembly operations, making installation quick and straightforward while ensuring precise fit
Solution Approach 2:
The flashing panel is designed to nest into the interruption space created by removing a portion of the tile layer. The offset portion fits into the gap between the interrupted tile layer and the lower tile layer, while the base sections lie against the tile surfaces, creating a nested configuration that simplifies installation
3Ease of operation
If the flashing panel uses a firm structure, then ease of installation is improved, but space occupation above the interrupted tile layer increases
Solution Approach 1:
The firmness of the flashing panel is localized to specific regions: the base sections are firm to provide stable contact with the tile surfaces and ease of installation, while the offset portion is configured to extend minimally into the interruption space. This local differentiation of properties allows the panel to be easy to install without occupying excessive space above the tiles

AI summary
There is disclosed a flashing panel for covering an interruption in an interrupted tile layer of a tiled roof, the interruption being where a portion of a tile of the interrupted tile layer is removed, the flashing panel comprising: a panel base comprising a first base section and a second base section; and an offset portion connecting the first base section to the second base section, wherein: the offset portion is configured to extend away from the panel base; the flashing panel is firm; and the panel base is configured to lie on the interrupted tile layer, the offset portion is configured to be positioned in the interruption of the interrupted tile layer such that the offset portion lies closer to a lower tile layer than the panel base, the interrupted tile layer overlaid on and in contact with the lower tile layer.
