Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for installing starter shingles on a roof deck are time-consuming and require significant effort, as they often necessitate cutting and arranging multiple pieces to ensure proper alignment and water protection, while also aiming to maintain an aesthetically pleasing appearance.
Innovation Solution
A method involving the manufacture and application of laminated starter shingles, comprising an underlay sheet laminated beneath an overlay sheet, which are arranged in a side-by-side course at the eave edge of the roof deck, allowing for efficient and visually cohesive installation of subsequent courses of covering shingles with tabs and cutouts, ensuring water protection and aesthetic continuity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional starter shingle installation methods are used (cutting and arranging multiple pieces), then water protection is achieved, but installation time and effort increase significantly
Solution Approach 1:
The patent combines multiple starter shingle pieces into a single pre-assembled unit that includes the first starter shingle piece, second starter shingle piece, and connector piece integrated together. This merging eliminates the need for installers to cut and arrange multiple separate pieces, significantly reducing installation time while maintaining the water protection function through the integrated structure.
Solution Approach 2:
The starter shingle unit is pre-assembled and pre-configured with proper alignment and spacing before reaching the installation site. The connector piece is already attached to join the first and second starter shingle pieces in the correct positions, allowing for direct installation without on-site cutting and arrangement, thus reducing installation time and effort.
2Reliability
If multiple pieces of starter shingle are used to ensure proper alignment, then water protection is improved, but the complexity of installation increases
Solution Approach 1:
The patent integrates multiple starter shingle pieces and connector pieces into a single pre-assembled unit, reducing installation complexity from managing multiple separate components to installing one integrated unit. The internal arrangement of pieces within the unit maintains proper alignment for water protection while simplifying the external installation process.
Solution Approach 2:
The starter shingle unit is segmented into functional components (first starter shingle piece, second starter shingle piece, connector piece) that are pre-arranged in the correct configuration. This segmentation allows each component to serve its specific function while the pre-arranged structure eliminates the need for complex on-site alignment and arrangement.
3Shape
If starter shingles are color matched and sealed to hide nails, then aesthetic appearance is improved, but installation time increases
Solution Approach 1:
The starter shingle unit is pre-assembled with color-matched components before installation. The first and second starter shingle pieces are selected or manufactured to match the roof shingle color, and the connector piece is pre-attached in the correct position, allowing installers to achieve aesthetic appearance without additional on-site color matching or sealing work.
Solution Approach 2:
The patent combines color-matched starter shingle pieces and connector pieces into a single integrated unit that maintains consistent appearance. The pre-assembled structure ensures proper alignment and spacing for aesthetic appearance while eliminating the need for separate color matching and sealing steps during installation.

AI summary
A method of covering a roof deck includes laying a course of starter shingles in a side-by-side relationship at an eave edge of a roof deck. A starter shingle of the course of starter shingles is a laminated starter shingle comprising an underlay sheet laminated below an overlay sheet. A plurality of successive generally horizontal courses of covering shingles are laid above the course of starter shingles. The covering shingles in each of the courses of covering shingles are laid in a side-by-side relationship and horizontally offset from the covering shingles in adjacent courses. Each covering shingle of the courses of covering shingles includes a headlap portion and a butt portion. The butt portion includes a plurality of tabs separated by cutouts. The starter shingles include an exposed portion extending between the tabs of the covering shingles.
