Shingle Repair Patch With Rigid Lip for Immediate Waterproofing
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 lead to leaks, and existing shingle patches with adhesives take too long to cure, making them unreliable for immediate repairs.
Innovation Solution
A shingle patch system with a base member that slides under existing shingles, featuring heat-activated sealants and integrated nails or adhesive strips, which can be quickly applied to cover damaged areas and exposed nails, providing immediate protection and matching the color of the existing shingles, allowing for repairs without removing the damaged shingles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional shingle replacement methods are used, then damaged shingles can be replaced, but the process is labor-intensive, time-consuming, and may cause damage to surrounding shingles
Solution Approach 1:
The repair system segments the repair task into a modular patch component that can be independently applied to damaged shingles without affecting surrounding areas. The patch includes a base member with sealant layers that can be precisely positioned and applied only where needed, eliminating the need to remove or manipulate adjacent shingles.
Solution Approach 2:
The patch base member acts as an intermediary element between the damaged shingle and the protective overlay. It includes a bottom sealant layer that adheres to the damaged shingle and a top sealant layer that provides the protective barrier, eliminating the need for direct manipulation of the damaged shingle itself.
2Ease of operation
If adhesive patches are used for shingle repair, then shingles can be repaired without removal, but the adhesives take a long time to cure and remain unreliable when wet
Solution Approach 1:
The patch employs a composite structure with multiple functional layers: a base member providing structural support, a bottom sealant layer for adhesion, and a top sealant layer for protection. This composite design combines the advantages of different materials to achieve both ease of application and immediate reliability.
Solution Approach 2:
The sealant layers are pre-applied to the base member during manufacturing, eliminating the need for现场 adhesive application and curing wait time. The patch is ready for immediate installation with full adhesive capability, eliminating the reliability issues associated with wet adhesive during installation.
3Strength
If nails are installed below the coverage zone, then shingles can be secured to the roof, but the nails remain exposed and corrode over time
Solution Approach 1:
The solution extracts the nail head from exposure by positioning the patch to cover the exposed nail area. The patch base member is designed to extend beyond the shingle edges, creating an overlapping configuration that shields the nail head from environmental exposure while maintaining attachment strength.
Solution Approach 2:
The patch provides beforehand protection by covering exposed nail heads before corrosion can occur. The overlapping design anticipates future corrosion risks and prevents them by creating a protective barrier that shields the nail heads from moisture and oxygen exposure.
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 system allows for rapid, cost-effective, and reliable repair of asphalt shingles by providing a double or triple layer of protection without the need to remove damaged shingles, ensuring immediate waterproofing and color matching, thus reducing labor and material costs while preventing further damage.
Implementation Method 1
The sealant is preferably heat activated and can be factory applied and is typically activated by the sun

AI summary
A shingle repair patch is provided that may include a base member and granules. 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.
