Roll Former LLC brought their FHA Drip Edge Machine to the Florida Roofing & Sheet Metal Association expo, and this clip shows the portable roll former producing finished drip edge profiles on the show floor. Drip edge is the L-shaped (or T-shaped) sheet metal flashing that runs along the eaves and rakes of a roof — its job is to direct water away from the fascia and into the gutter rather than letting it wick back under the shingles and rot the deck.

The "FHA" profile is a Florida-specific high-wind variant with a longer kickout leg, designed to meet the state's tightened roofing code after the post-Andrew rewrites. What's worth watching here is the roll forming process itself: instead of bending each piece on a brake, a coil of pre-painted aluminum or galvanized steel is fed through a series of staged rollers that progressively form the profile as it travels through the machine. It's a great example of continuous forming vs. discrete bending — higher throughput, consistent geometry, and on-site production from a single coil.

For roofers, sheet metal fabricators, or anyone curious about job-site machinery, it's a quick look at how specialty trim gets made where it's installed rather than shipped pre-formed.
