Step Flashing

Where a roof meets a wall, water finds a way in unless the flashing is right. CL Aluminum’s step flashing gives contractors, roofers, shed manufacturers, and wholesale buyers a pre-bent, L-shaped aluminum piece that layers with each shingle course and channels water down and away from the siding. The result is a sealed roof-to-wall joint that helps protect against leaks and rot.

Every piece is bent to a consistent profile, so crews skip the on-site bending and keep moving. Choose 3"x3"x8" or 4"x4"x8" in 0.015 or 0.019 gauge, packed 500 pieces to a box and ready for high-volume jobs, production runs, and resale stock.

Benefits of Aluminum Flashing

Pre-Bent for Fast, Consistent Installation

Rust-Proof Aluminum for Long-Lasting Protection

Channels Water Away from Roof-to-Wall Seams to Prevent Rot

Why Contractors and Shed Manufacturers Choose CL Aluminum

Made in America, at our own facility. Every piece is manufactured in-house, so the bends stay consistent from one box to the next.
Two sizes and two gauges for any project. Choose 3"x3"x8" or 4"x4"x8", in 0.015 gauge for lightweight handling or 0.019 gauge for added rigidity, so you can match the joint without over- or under-building it.
Packed for volume. With 500 pieces per box and 25,000 pieces per pallet, high-volume jobs and production runs stay supplied.
Color options that match the job. Step flashing comes in white, black, and brown, and you can request boxes in different colors when you order.
Factory-direct pricing for contractors big and small. Buying straight from the manufacturer means better pricing for contractor jobs, production runs, and resale stock.
Reliable service from order to delivery. Our family-run team gives a small contractor’s first order the same attention as a standing account.

FAQs

Step flashing is a pre-bent, L-shaped aluminum piece installed where a roof meets a vertical wall. Each piece layers with a shingle course to channel water away from the siding, helping prevent leaks and wood rot at that joint.

The 3"x3"x8" size suits tighter spaces and standard residential roof pitches. The 4"x4"x8" size is a strong fit for standard residential roofing, and in 0.019 gauge it is a go-to for commercial buildings and high-end residential roofs. Always follow local code and the roofing manufacturer’s requirements.

0.015 gauge is lightweight and easy to handle and form on the roof. 0.019 gauge is thicker and more rigid, which helps it resist bending and denting during installation and under the weight of snow and debris.

Each box holds 500 pieces, and a pallet holds 50 boxes for a total of 25,000 pieces.
