Integral Nail Disk Structure for Exposed Roof Nails
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for repairing hail damage and sealing exposed nails on asphalt shingles are labor-intensive, time-consuming, and inefficient, leading to premature degradation of caulking and potential leaks, with existing solutions failing to provide a durable and cost-effective solution for matching the color and longevity of the shingles.
Innovation Solution
A shingle patch with a heat-activated sealant and integrated nail/disk structure that can be applied without removing damaged shingles, featuring colored granules to match existing shingles, and an asphalt emulsion injector system for sealing damaged areas, along with tools for lifting shingles and breaking up sealant, to provide a durable and color-matched repair.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional caulking methods are used to seal exposed nails, then the nails are covered, but the caulking degrades quickly and requires frequent reapplication
Solution Approach 1:
The patent replaces traditional caulking with disposable nail covers that are pre-applied to nail heads before shingle installation. These covers are designed to last the lifetime of the roof without degrading, eliminating the need for frequent reapplication and maintenance of sealant.
Solution Approach 2:
The nail covers are applied to nail heads before the shingles are installed, rather than attempting to seal exposed nails after installation. This preliminary action ensures proper sealing from the start and eliminates the need for later maintenance.
2Reliability
If individual shingles are removed for repair, then damaged shingles can be replaced, but the process is labor-intensive and time-consuming
Solution Approach 1:
The patent allows for replacement of individual damaged shingles without requiring removal of surrounding shingles. Each shingle can be independently accessed and replaced by simply removing its nail covers and nails, then installing a new shingle with pre-applied nail covers.
Solution Approach 2:
The nail covers are designed to be easily removed from nail heads, allowing individual shingles to be accessed and replaced without disturbing adjacent shingles. This extraction of the sealing function from the shingle installation process enables efficient individual repair.
3Device complexity
If exposed nails are left uncovered, then the roof structure remains simple, but the nails corrode and lose grip over time
Solution Approach 1:
The nail covers are designed to be self-sealing and self-protecting structures that automatically protect nail heads from corrosion without requiring additional sealing steps or maintenance. The covers are integrated into the shingle installation process itself.
Solution Approach 2:
The nail covers are made from materials that are both corrosion-resistant and aesthetically pleasing, combining protective function with visual appearance to match the shingle color and texture.

AI summary
An integral one-piece nail/disk structure which eliminates the need of having any exposed nails associated with a shingled roof, the nail/disk structure including a body member having a roofing nail incorporated or encapsulated therewithin and having color granules associated with at least a portion of the top surface of the body member. The nail/disk structure may include a sealant covering at least a portion of the bottom surface of the body member. The roofing nail is integrally formed with the body member.
