Electrical Mast Connection

This electrical mast flashing is specifically designed to seal around overhead service masts that penetrate the roof, protecting against water intrusion at this critical connection point. Featuring a formable aluminum base and a high-heat rubber collar with a built-in split for easy wraparound installation, it provides a watertight seal without needing to disconnect service lines. Ideal for asphalt shingle roofs, it's a reliable solution for both new construction and retrofit projects.
