Inclined Shingle Testing Tool for Hail Damage Assessment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for assessing hail damage to asphalt shingles lack objective standards and procedures, leading to inconsistent testing results and unnecessary expenditures, as professionals struggle to determine if damaged shingles can be repaired without affecting surrounding ones, often resulting in premature roof replacements.
Innovation Solution
A shingle testing tool comprising a base member and an inclined shingle support plate with measurement graduations, allowing for precise determination of the pliability and repairability of asphalt shingles, providing measurable evidence of lift versus clearance for fastener placement and hammer swing, thus standardizing the inspection process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If visual inspection methods are used to assess shingle damage, then inspection speed is maintained, but measurement precision and reliability of assessment deteriorate due to lack of objective standards
Solution Approach 1:
The patent introduces an inclined support plate as an intermediary tool between the inspector and the shingle. This plate provides a standardized reference surface with measurement markings that mediate the assessment process, allowing inspectors to objectively measure shingle lift and curvature without requiring complex equipment while eliminating subjective visual estimation
Solution Approach 2:
The patent changes the assessment parameters from subjective visual categories to objective measurable quantities. By using the inclined support plate with graduation markings, inspectors can measure specific parameters such as shingle lift height and curvature angle, transforming the assessment from qualitative to quantitative and thereby improving precision without adding significant complexity
2Reliability
If conservative repair recommendations are made without proper assessment, then reliability of repair decisions improves, but loss of time and productivity worsen due to unnecessary roof replacements
Solution Approach 1:
The patent enables preliminary objective assessment of shingle condition before making repair decisions. By using the standardized tool to measure shingle lift and curvature in advance, inspectors can determine with confidence whether shingles are structurally sound enough for repair, preventing both unnecessary replacements and premature repairs, thereby improving reliability without sacrificing productivity
3Measurement precision
If standardized testing procedures are implemented, then measurement precision and reliability improve, but ease of operation deteriorates due to additional procedural steps
Solution Approach 1:
The inclined support plate is designed to be self-aligning and self-measuring. When placed against the shingle, the tool automatically provides the inclined reference surface, and the graduation markings on the plate itself provide the measurement readings directly. This self-service design standardizes the testing procedure without requiring complex setup or additional操作步骤, maintaining ease of operation while improving precision

AI summary
A shingle testing tool includes a base member and an inclined shingle support plate. The inclined shingle support plate intersects a first end of the base member at a leading convex edge. The inclined shingle support plate defines one or more shingle structural reliability measurement graduations. The shingle testing tool can be used to determine if a damaged shingle can be replaced without damage to another shingle overlapping the damage shingle.
