Weathered Corrugated Metal Roofing Panels

Real weathering metal roofing panels with the look of a hundred-year-old barn roof - without the hundred-year wait. Every sheet is corrugated steel, finished or sourced by Dakota Tin to age the honest way: out in the weather. Put it on a house, porch, cabin, shed, cupola, barndominium, or a commercial build that should look like it's always been there.

Choose your finish, length, and quantity in the quote form , and we'll send back one all-in price including freight. All three are roofing-grade corrugated steel in the same old-fashioned profile - what changes is how each one ages (or doesn't) and the look you're after.

The real old-fashioned corrugation. These are narrow, small-wave panels - about 1.25" from peak to peak - the same tight profile you see on hundred-year-old barns, not the wide 2.5" corrugation on most modern metal roofing. It's a big part of why these roofs read as authentically old, not brand-new. (See the profile drawing in the photos.)

Corten Weathering Steel Roofing Panels - 24 gauge

The real thing. A606 weathering steel ships bright and raw - not pre-rusted , then grows its own rust-orange patina over a few months of sun and rain. Once the Corten steel roofing panel sets, it turns self-protecting - the rust layer shields the steel underneath instead of eating through it, so there's no clear coat or repainting to keep up. It's the thickest and most durable of the three options.

About the photos - please read: the rust-orange color in our Corten photos and swatches is how it looks after it weathers - the finished result, not how it ships. Fresh Corten arrives a raw silvery-grey and takes a few months of sun and rain to color up. Want the rust look from day one? We can pre-rust your Corten for $1 per running foot - just request it on your quote, and we'll start the patina before it ships.

Straight talk: while Corten weathers, it sheds rust-colored runoff, and that runoff will stain whatever sits below it - gutters, fascia, siding, concrete, walkways, plantings. Plan your flashing and drainage around it, or lean into it. This is true weathering steel doing exactly what it's built to do.

Antique Bonderized Galvanized Metal Roofing Panels - 26 gauge

A weathered, flat-grey finish with the look of an old galvanized metal roof. We start with G90 galvanized, bonderized (the "paint-grip" surface some builders know as a Resbond-type finish), and leave it bare so it reads aged from day one.

Straight talk: bonderized steel is built as a paint-prep surface, and left bare it keeps moving - expect uneven tone, streaking, and white-rust spotting as it weathers. Here, that patina is the point, not a flaw. Want to freeze the look it has now? It takes a clear coat well, and we offer a protective sealant add-on.
