Expert Verdict — Reviewed by the SuperArbor Pro Desk
Roll flashing is the economical way to form drip edge and custom details when you already have a brake on the truck. At 30 GA, this galvanized stock is easy to bend but still holds shape at the eave. Form 10 ft. lengths with the 1/8 in. hem out, and overlap pieces in the direction of water flow to avoid backups under the shingles.
Coiled steel flashing is under tension when cut; secure the roll before cutting and wear gloves, as cut edges are sharp.
