Quality Edge Aluminum Prebent Step Flashing 7 in. Leg, Mill or White, 2 in. x 3 in. and 2-1/2 in. x 2-1/2 in.
Quality Edge Aluminum Prebent Step Flashing is factory-formed .011 aluminum step flashing for roof-to-wall transitions, protecting the joint where siding or brick meets roof sheathing. Two variants are listed: 2 in. x 3 in. x 7 in. in mill finish (board) and 2-1/2 in. x 2-1/2 in. x 7 in. in White 280 (piece). Install beneath each shingle course to keep water from flowing back up onto the wall.
Key Features:
- Prebent profile: Factory-bent legs save on-site brake time and keep each piece consistent.
- Wall-to-roof protection: Provides a protective layer between the wall's siding or brick and the roof's sheeting.
- Stops back-up water: Keeps water from flowing back up onto the wall.
- Prevents rot: Helps prevent mold and wood rot at vulnerable wall-roof intersections.
- Light aluminum: .011 in. aluminum is easy to cut, form and nail in the field.
- System-matched flashing: Part of Quality Edge's range of flashing solutions designed to maximize roof, window and wall life.

Expert Verdict — Reviewed by the SuperArbor Pro Desk
Never let step flashing be visible on the finished wall face; lap shingles over the vertical leg and keep the horizontal leg under the course above. Choose the 2-1/2 in. width when the wall detail is wider or siding reveals require extra coverage. Aluminum is the right pick for most shingle roofs, but confirm galvanic compatibility with any adjacent steel products.
Cut aluminum edges are sharp; wear gloves and eye protection, and work from secure ladder or roof anchorage when flashing wall transitions.
Order Quality Edge prebent aluminum step flashing to seal your roof-to-wall transitions right.
