TopShield Aluminum Angle Flashing, Mill, White or Brown, 4" x 5" and 5" x 5" Sizes


TopShield aluminum angle flashing is an L-shaped transition and edge flashing available in 5 in. x 5 in. (.032 and .025) and 4 in. x 5 in. (.025) sizes. Color choices are mill, white and brown, and most items sell per board (BD) with the 4 in. x 5 in. mill option sold per piece. It covers wall-to-roof, fascia and edge transitions on residential roofs.


Key Features:

  • Aluminum construction: Lightweight aluminum resists rust and is easy to bend and cut on site.
  • Two profile sizes: Offered in 4 in. x 5 in. and 5 in. x 5 in. leg combinations.
  • Gauge options: Available in .032 aluminum for the 5 in. x 5 in. mill profile and .025 for other variants.
  • Three finishes: Mill, white and brown finishes let you match trim colors.
  • Clean L-profile: Right-angle profile bridges transitions and provides a straight drip or termination edge.
  • Flexible ordering: Sold per board (PC for one mill variant) so you can buy the run length you need.

Q: Is this aluminum rust-proof?
A: Aluminum does not rust like steel; it forms a protective oxide, making it well suited for exterior flashing.

A: .032 aluminum is stiffer for longer exposed runs; .025 is easier to work with for shorter details.


Q: How is it sold?

Q: Can it be cut on site?
A: Yes, aluminum flashing cuts easily with tin snips or a metal shear.


Expert Verdict — Reviewed by the SuperArbor Pro Desk

Angle flashing is one of the most versatile pieces on the truck: use it as a termination edge, drip edge detail or counter-flashing leg where a softer L-shape is enough. Choose .032 when the exposed leg runs long or will take handling; step down to .025 for tight miters and smaller details. Match white or brown to the trim color so the line disappears into the roof-to-wall detail.

Wear gloves and eye protection when cutting aluminum flashing; cut edges are sharp.
