Elastomeric Roofing Coating with Embedded Granules for Hail Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Commercial roofing systems with exposed membranes are vulnerable to hail damage and UV degradation, lacking effective protection methods that combine hail resistance and UV protection.
Innovation Solution
A Special Liquid Applied Hail and Rain Protection Process using a multi-layered coating system with Styrene-Butadiene-Styrene (SBS) or Styrene-Ethylene-Betadine-Styrene (SEBS) elastomeric materials embedded with fiberglass or stone granules, applied in multiple layers to create a continuous, seamless, waterproof surface that can be applied over various structural components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional exposed membrane roofing systems are used, then the roofing structure remains simple and cost-effective, but the roof is highly vulnerable to hail damage and UV degradation
Solution Approach 1:
The patent applies composite materials by combining elastomeric coating with embedded stone granules and fiberglass reinforcement to create a multi-component protective system. This composite structure provides both hail impact resistance through the granular surface and UV protection through the elastomeric matrix, resolving the contradiction between reliability and simplicity by integrating multiple protective functions into a unified applied coating system
2Reliability
If traditional exposed membrane roofing systems are used, then the installation process remains straightforward, but the roof suffers from UV degradation and premature aging
Solution Approach 1:
The elastomeric coating system performs multiple functions simultaneously: it provides UV protection through its chemical composition, creates a waterproof barrier, and serves as an adhesive matrix for embedding protective granules. This multi-functionality resolves the contradiction by delivering comprehensive protection (UV, hail, water) through a single applied coating system rather than requiring separate layers for each protective function
3Reliability
If liquid applied coating systems are used to protect against hail and UV, then comprehensive protection is achieved, but the application process becomes time-consuming and labor-intensive
Solution Approach 1:
The patent merges the protective functions of multiple separate coatings into a single liquid applied composition that contains elastomeric binders, stone granules, and fiberglass reinforcement all in one formulation. This consolidation allows the entire protective system to be applied in a single operation rather than requiring sequential application of multiple separate layers, thereby improving productivity while maintaining comprehensive weatherproofing effectiveness

Function Achieved in This Case
The process provides faster application, reduced labor and costs, eco-friendly materials, off-site panel production, reduced construction timelines, and enhanced resistance to hail storms and UV degradation, resulting in a tougher, longer-lasting roofing solution.
Implementation Method 1
coating the selected surface with a base elastomeric coating thus sealing holes, cracks, and other surface imperfections
Implementation Method 2
embedded with fiberglass or stone granules, applied in multiple layers to create a continuous, seamless, waterproof surface

AI summary
A liquid applied hail and rain protection roofing material for commercial applications and the process for applying the commercial roofing materials. This is an elastomeric material which is embedded with fiberglass and/or granules of stone-like rubber rock to provide for strength and to resist the hail. An Ultraviolet Ray protection can also be applied. The materials utilized increase the utility as a roofing membrane by making it more elastic and by resulting in greater flexibility at low temperatures and in greater heat resistance at high temperatures. This flexibility prevents softening/flow and deformation from mechanical forces, such as those associated with maintenance personnel walking on the roofing membrane. A roofing membrane may be formed of the material as a laminate of a plurality of types of modified layers at the worksite pre-made as panels then installed at the worksite.
