Rexocap Fastener Seal System

REXOCAP is a patent-pending screw head sealing system that provides permanent protection for exposed roof fasteners. Its innovative aluminum-faced butyl patch compresses and conforms tightly around the screw head to create a durable, waterproof seal that prevents leaks before they start. Unlike traditional plastic screw caps that simply cover the fastener, REXOCAP creates a true compression seal and is fully encapsulated with Rexoseal Steelshield®, forming a seamless protective barrier against water, UV exposure, corrosion, and harsh weather. The result is unmatched long-term protection for metal roofs, RV roofs, and other exposed fastening systems.
