Thunderbird Products

Thunderbird Products is a San Diego-area manufacturer of copper and stainless steel roof drains, deck drains, scupper and parapet drains, vents, and pipe flashings. Based in El Cajon, California, Thunderbird has manufactured in the USA for over 35 years, with in-house waterjet cutting and press-brake capabilities for custom architectural sheet metal work in copper, stainless steel, aluminum, brass, and titanium.

Their deck drain line is built around sandblasted copper flashing that bonds cleanly to fluid-applied and single-ply waterproofing membranes — a detail that has made their balcony and patio drains a go-to for residential and light-commercial deck and balcony work on the West Coast. Many units carry an ICC-ES PMG listing.
