One-piece Shingle Repair Patch with Heat-Activated Sealant
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for repairing asphalt shingles are labor-intensive, time-consuming, and costly, especially for hail damage, as they require removing damaged shingles, which can cause further damage and are not cost-effective for widespread damage scenarios, and existing shingle patches with adhesives take too long to cure, posing safety risks and being prone to wind displacement.
Innovation Solution
A shingle patch system that includes a base member with a notched portion for sliding under existing shingles, embedded colored granules for color matching, and a heat-activated sealant for quick bonding, allowing for overlaying damaged shingles without removal, and optionally featuring an integrated nail or double-sided adhesive tape for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional adhesive patches are used to repair shingles, then the patch can be applied without removing damaged shingles, but the adhesive takes a long time to cure and the patch can be dislodged by wind or foot traffic
Solution Approach 1:
The patch is divided into multiple layers: a base layer with adhesive, a reinforcement layer with mesh or fabric, and a top layer with granules. This segmentation provides both ease of application and strong, reliable bonding that resists wind and foot traffic.
Solution Approach 2:
The patch uses composite materials combining adhesive, reinforcement mesh, and granule layers to achieve both easy application and high bond strength. The composite structure provides immediate structural integrity while maintaining ease of installation.
2Reliability
If damaged shingles are removed for repair, then the repair can be thorough and durable, but the process is labor-intensive, time-consuming, and may cause damage to surrounding shingles
Solution Approach 1:
The patch is pre-manufactured with all necessary components (adhesive, reinforcement, granules) integrated, allowing for immediate application over damaged shingles without the need to remove them. This preliminary preparation enables fast repair while maintaining durability.
Solution Approach 2:
The patch replicates the appearance and function of original shingles, providing a durable repair that matches surrounding areas. The granule-covered surface mimics the texture and color of authentic shingles while providing protective functionality.
3Strength
If nails are installed below the coverage zone, then shingles can be secured to the roof structure, but the nails remain exposed and susceptible to corrosion and leaking
Solution Approach 1:
The patch combines the functions of nail coverage and shingle reinforcement into a single component. The patch is designed to be positioned over exposed nails, merging the protective coverage function with the structural reinforcement function in one integrated solution.
Solution Approach 2:
The patch serves multiple functions simultaneously: it covers exposed nails, reinforces damaged shingle areas, provides adhesive bonding, and restores the protective granule surface. This multi-functionality addresses both attachment strength and protection from environmental elements.
4Ease of operation
If adhesive is applied to shingle patches, then the patches can be installed without nails, but the adhesive remains wet for hours or days and offers little retention during this period
Solution Approach 1:
The reinforcement layer (mesh or fabric) is embedded in the adhesive layer before application, providing immediate structural support and cushioning. This prevents the patch from being dislodged by wind or foot traffic during the adhesive cure period, maintaining both ease of installation and security.

Function Achieved in This Case
The shingle patch system provides a rapid, cost-effective, and safe solution for repairing hail damage and covering exposed nails by allowing for in-place repair without removing damaged shingles, offering immediate protection and matching the color scheme of existing shingles, while minimizing further damage and granule loss.

AI summary
A shingle repair patch is provided that may include a base member and granules as discussed in detail above. An adhesive strip is positioned proximate an upper edge on the underside of the base member, or elsewhere on the underside of the base member. The adhesive strip preferably permanently bonds a rigid lip to the base member. The rigid lip preferably extends beyond the upper edge of the base member. An adhesive strip may be positioned on at least a portion of the bottom side of the rigid lip. Release tape is temporarily affixed to the adhesive strip. The adhesive strip is composed of an adhesive that adheres securely without an extended or heat-induced cure period. Standard adhesive may be applied to the remainder of the bottom of the base member, or further adhesive like that found in the adhesive strip may be applied to the remainder of the bottom of the base member.
