FAQs

Aluminum flashing is thin metal used at critical joints—such as roof edges and roof-to-wall transitions—to keep water out. It directs runoff away from fascia, sheathing, and wall joints to prevent leaks and rot, and to meet building code requirements.

Drip edge is installed along the roof edges to guide water away from the fascia and into gutters. Step flashing is used where a roof meets a vertical wall; pieces are layered with each shingle course to seal that joint and prevent water intrusion.

Yes. They’re designed and bent to meet common residential building code requirements for roof edge protection and roof‑to‑wall flashing when installed according to local code and manufacturer guidelines.

Bulk and custom orders are welcome. If you need a special bend, length, or color, reach out through the Contact form so the team can quote a custom run.
