Supersider 1 in Step Flashing 26ga White - Sold by Foot

Clear Ordering Note: Sold by Foot, Shipping Length Limited to 8 ft

This flashing is priced and sold by the foot. Select the total footage needed for the run, repair, or fabrication plan. Because long metal pieces are expensive and difficult to ship safely, shipped lengths must be limited to 8 ft or shorter.

• Sold by foot: order the total number of feet needed.
• Maximum shipped length: 8 ft per piece due to the cost and handling risk of long items.
• Longer pieces: use in-store pickup or local delivery when available.
• Color: white finish.
• Check before ordering: confirm total footage, piece length, roof-to-wall detail, siding overlap, and whether pickup, local delivery, or shipping is the right choice.

Key Benefits at a Glance

Roof-to-Wall Water Damage Starts Small, Then Gets Expensive

The roof edge, wall line, siding overlap, and gutter area all meet in a narrow zone where water can slip behind finishes if the metal transition is not planned correctly. That can lead to stained siding, soft sheathing, hidden rot, callbacks, and repairs that cost far more than the flashing detail.

This Supersider 1 in step flashing gives installers a defined metal profile for those vulnerable transition areas: a 4 in wall leg, 1 in step, white 26ga metal construction, and sold-by-foot ordering for measured roof-to-wall runs.

Built for Clean Roof, Siding, and Gutter Transitions

Supersider 1 in Step Flashing is a white 26ga metal flashing profile for roof-to-wall, siding, and gutter-adjacent transition details. The profile image shows a 4 in vertical leg, 1 in step, and lower return detail marked 3/8 in, 3/8 in, and 1/4 in.

For gutter installers and exterior contractors, the value is cleaner water management at the point where roof runoff, wall cladding, and gutter systems interact. The flashing helps create a controlled transition where siding, roofing, and drainage components need to work together instead of leaving water a path behind the wall finish.

This product is sold by the foot. Shipped pieces must be 8 ft or shorter because long flashing is costly to package and ship safely. For longer pieces, choose in-store pickup at GutterAll in Damascus, Oregon or ask about local delivery before checkout.

Why This Flashing Detail Matters

Roof-to-wall transitions are one of the first places exterior water control can fail because water is moving from the roof plane toward a wall, siding edge, gutter, or termination point. If the metal detail is missing, undersized, poorly lapped, or cut too short, water can move behind the finished surface.

This profile gives contractors a measured flashing option for transition work where a compact step and tall wall leg are needed. It is useful for siding integration, low-slope edge details, wall transition repairs, and gutter-adjacent water control when the job calls for this shape and size.

The cleanest order starts with three checks: the total footage needed, the longest piece length needed, and whether the material is being picked up, delivered locally, or shipped in 8 ft or shorter pieces.

Contractor Applications

How the Flashing Profile Works

The 4 in vertical leg rises behind siding, trim, or the wall-side covering. The 1 in step projects out to bridge the transition area. The lower formed return helps finish the profile edge and gives the piece its Supersider shape.

Installed correctly, flashing works as part of a layered water-control system. Roofing, siding, housewrap or weather barrier, kick-out flashing where needed, fasteners, sealant, and gutter placement all need to work together so runoff moves outward and down instead of behind the wall.

Who Uses This Flashing?

Setup and Application Guide

1. Measure the total roof-to-wall or siding transition length that needs flashing.
2. Decide the piece lengths needed before ordering, remembering that shipped pieces are limited to 8 ft.
3. Choose pickup or local delivery for longer pieces where available.
4. Confirm the white 26ga profile matches the exterior finish, siding detail, and project requirement.
5. Check that the 4 in wall leg and 1 in step fit the intended roof and siding transition.
6. Plan lapping, siding overlap, kick-out flashing, and drainage path before fastening.
7. Cut flashing with appropriate metal tools and protect cut edges where the project requires it.
8. Install flashing as part of the full roof, wall, siding, and drainage assembly.
9. Direct runoff outward and toward the gutter or approved drainage point.
10. Inspect the finished detail for gaps, reverse laps, open seams, sharp edges, loose fasteners, and areas where water can move behind the wall covering.

Pro Tip

Before cutting, mock up the flashing with a short sample at the roof-to-wall transition. Check siding overlap, gutter outlet location, roof slope, and whether a kick-out piece is needed at the bottom of the run. One dry-fit can prevent a whole run from being ordered or cut wrong.

Frequently Asked Questions

Cutting, Handling, and Installation Safety Notice

Metal flashing can have sharp edges, especially after cutting. Use gloves, eye protection, safe cutting tools, and proper handling practices.

Roof, siding, and gutter work may involve ladders, roof edges, power tools, and fall hazards. Use safe access methods and follow applicable jobsite safety requirements.

Flashing must be integrated with the full exterior water-control system. Poor lapping, missing kick-out details, exposed gaps, weak fastening, or incompatible metals can reduce performance.

Need Help Confirming Footage, Piece Length, or the Right Transition Detail?

The right order depends on total footage, piece length, shipping limit, roof-to-wall layout, siding overlap, color, pickup, delivery, and whether additional flashing pieces are needed. Website chat is the fastest way to confirm before checkout.
