ChimFlash: The Next Generation Flashing System For Masonry
ChimFlash is a high-performance, field-applied elastomeric flashing system designed to permanently seal the most failure-prone area of the chimney — where the roof meets masonry. It forms a seamless, waterproof membrane that flexes with structural movement without cracking, lifting, or leaking.
Key Features:
- Advanced Protection: Helps permanently seal the roof-to-chimney transition against water intrusion.
- Flexible Formula: Moves with the structure without cracking, lifting, or leaking.
- Durable Performance: Creates a UV-stable, weather-resistant membrane for long-term exterior exposure.
- Easy Application: Field-applied solution ideal for repairs, restorations, and new installations.
- Modern Flashing Solution: Replaces common failure points with a performance-based waterproofing system contractors can stand behind.
Why Traditional Flashing Fails
- Roof and masonry movement break sealants
- Metal flashing relies on seams and fasteners
- Counter flashing gaps lead to water intrusion
- Repeated maintenance and callbacks are common
The ChimFlash Difference
Traditional flashing fails because it relies on joints, seams, and fasteners—the exact places where water eventually finds a way in. ChimFlash eliminates those vulnerabilities entirely.
By creating a seamless, monolithic barrier, ChimFlash forms a permanent, watertight bond to masonry, metal, and existing roofing materials. Engineered to stay permanently flexible, it moves naturally with your building’s thermal expansion and structural shifts without cracking or breaking seal. UV-stable and built to withstand harsh weather, it applies quickly with minimal disruption to your roof.
