Description
The ChemLink ChemCurb 5 In. One-Part Kit is a pre-engineered curb flashing system used to seal roof curbs and penetration assemblies as part of the ChemCurb system. It’s designed to create a continuous transition between the roofing membrane and curb surfaces using a coordinated set of components rather than field-built detailing.
This kit is supplied as a one-part system to simplify application and maintain consistency across curb installations. The 5-inch configuration is intended for projects where a formed curb flashing solution is preferred over assembling individual materials on the roof.

- 5-inch curb configuration
- One-part system (no field mixing required)
- Supplied as a complete system kit

Installation
Bonding surfaces should be clean, dry and free from all contamination that may inhibit the sealant’s performance. Remove all previously applied caulk, mastic, cement, asphalt, and other contaminants from penetrations with a wire brush. Brush away all gravel or loose granules. Isopropyl alcohol is an effective cleaner for surface preparation. Please contact customer service for application guidelines with temperatures below 32°F (0°C). Do not use on TPO without the use of TPO primer. Do not use on Hypalon. Smooth APP membranes require a granulated target. This product sets rapidly upon exposure to moisture. Please refer to data sheet for step-by-step installation guidelines.
FAQs
Q: What’s the advantage of using a dedicated curb flashing system?
A: A dedicated system provides a defined method for handling curb transitions instead of relying on job-by-job detailing.
Q: Why are curb details often handled differently than other roof penetrations?
A: Curb transitions introduce multiple planes and materials, which is why they’re commonly addressed with a purpose-built flashing system.
Q: Where does ChemCurb fit within a complete roofing assembly?
A: It’s intended to function as part of the overall curb flashing approach rather than as an isolated sealant application.
