Siding Flashing
Every penetration, transition, and termination in a metal siding job needs flashing. We fabricate every piece to match your panels, your wall, and your specs.
What We Build
Metal siding looks incredible — until water finds a way in through an unflashed penetration or a poorly detailed transition. Every window, door, vent, meter base, hose bib, and material change needs purpose-built flashing to keep the wall dry.
We fabricate the full range of siding flashing and transition trim: J-channel, Z-flashing, starter strips, termination bars, utility penetration boots, and material transition pieces. All custom-sized and color-matched.
Receives panel edges at windows, doors, and soffits. Custom depth to match your panel profile thickness.
Horizontal transition between different materials or panel orientations. Integrated drip leg sheds water outward.
Base attachment for the first course of siding panels. Provides a consistent, level starting line.
Clean top termination for siding that ends mid-wall, at soffits, or at material transitions.
Materials
Every piece of trim we fabricate is available in any standard color from Metal Sales Manufacturing and AEP Span — 30+ colors between the two lines. We also work with Galvalume, bare steel, aluminum, copper, and stainless steel from Pacific Steel & Recycling.
Standard gauges: 24, 26, and 29 gauge for painted steel. Heavier gauges available for structural and specialty applications. All trim is brake-formed in our Reno shop on the same equipment we use for roofing panels, kitchen hoods, and architectural metalwork — so tolerances are tight and finishes are clean.
