Heat-Activated Shingle Patch for Hail Damage Repair
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for repairing hail damage to asphalt shingles are labor-intensive and inefficient, and exposed roofing nails on shingled roofs corrode, leading to premature leaks and the need for frequent caulking, which is messy and wasteful.
Innovation Solution
A shingle patch with a heat-activated sealant and integrated nail/disk structure that can be used to overlay damaged shingles without removal, eliminating exposed nails by matching the color of existing shingles and providing a durable seal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If current replacement methods are used to repair damaged shingles, then the damaged shingles can be replaced, but the process is labor-intensive and time-consuming
Solution Approach 1:
The invention divides the repair process into two distinct components: a patch member that covers the damaged shingle and a sealant member that seals the underlying shingle. This segmentation allows the patch to be applied independently without requiring removal of surrounding shingles, significantly reducing labor time while maintaining repair effectiveness
Solution Approach 2:
The patch member is designed with pre-applied sealant on its bottom surface, which is activated by heat from the sun or other heat sources. This preliminary preparation of the sealant allows for rapid installation without requiring separate sealing steps, improving both repair speed and reliability
2Reliability
If exposed roof nails are sealed with caulking, then nail corrosion is prevented, but the process is messy and the caulking degrades quickly
Solution Approach 1:
The invention extracts the nail sealing function from the traditional caulking process and integrates it into the patch member itself. The sealant member is specifically designed to seal the exposed nail heads, providing a dedicated solution that is applied as part of the standard patching process, eliminating the need for separate messy caulking operations
Solution Approach 2:
The patch member combines multiple materials and functions: the patch material itself, pre-applied sealant, and color-matching granules. This composite structure provides both cosmetic repair and functional sealing in a single integrated component, improving ease of operation while maintaining reliable nail protection
3Reliability
If individual shingles are removed for repair, then damaged shingles can be replaced, but surrounding shingles must be lifted and separated
Solution Approach 1:
Instead of removing the damaged shingle and replacing it from below, the invention applies the patch member from above, overlaying the damaged shingle. This inverted approach eliminates the need to lift surrounding shingles or access the roof from below, significantly simplifying the repair process while maintaining effective protection
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 shingle patch and nail/disk structure offer a faster, more cost-effective solution for repairing hail damage and sealing exposed nails, providing long-lasting protection against corrosion and leaks while matching the color of existing shingles, thus extending the life of the roof.

AI summary
A method for repairing damaged asphalt shingles includes inserting a tube under the damaged shingle such the terminal end of the tube lies in the vicinity of the damaged area of the shingle, pushing a liquid emulsion through the tube and under the damaged shingle in and around the damaged area, applying a sealant to the upper face of the damaged shingle to fill and seal the damaged area, applying color granules to the sealant to match the granules associated with the damaged shingle, and allowing the sealant and liquid emulsion to seal the damaged area. The method may also include forming a hole in the center of the damaged area of the shingle and applying a sealant through the tube into the hole in sufficient quantity to allow the sealant to spread underneath the damaged shingle and around the damaged area of the shingle, filling the hole with a liquid emulsion, and applying colored granules to the liquid emulsion.
