Shipping
Large caps ship via LTL freight in a custom-built, heat-treated wood crate, fully insured. I need your exact dimensions, address type (residential or commercial), and zip code before you order. Call or text (text is best) (609) 352-9840 to receive a custom freight quote. LTL freight means your order will arrive on a full-size tractor-trailer. The driver will bring the crate to the back of the truck with liftgate service — curbside delivery. You are responsible for getting it up your driveway from there. Delivery add-ons are available if needed. If your property can't accommodate a full-size freight truck or you don't have help moving the crate from the curb, I can arrange delivery add-ons for the freight company to move the crate to a designated area on or inside your property. Terminal pickup and smaller delivery vehicle options are also available. This way it arrives the way it left my shop — in perfect condition.
How to Order Full Size Caps
Select your approximate chimney width and approximate chimney length using the size selectors above. Your cap will be custom fabricated to your exact dimensions — add a minimum of 1/4" to your measurements for proper fit.
Contact me with your chimney dimensions and zip code before purchasing and I'll confirm sizing and provide an exact shipping quote. Lead time is 3–4 weeks from measurement confirmation.

Have a Wood-Framed Chase?
If your chimney sits on a prefab wood-framed chase, you'll need a chase cover in addition to this cap. The cap mounts on top of the chase cover — it does not have a flat bottom with pre-cut holes for your flue pipe(s). If there's currently no metal cover on your chase, you need both.

The Standing Seam Copper Chimney Cap
Where the curved panel cap has a convex flare, the standing seam reads architectural and restrained — flat standing seam panels rising to a clean hip roof. Clean lines. Precise geometry. A cap that complements the architecture without competing with it. It works on traditional homes, transitional designs, and anywhere the roofline calls for structure without ornament.
Every standing seam cap I build is fabricated by hand in my Berlin, NJ workshop from 16oz cold-rolled copper — the same material used on historic buildings and high-end architectural projects throughout the region. Each panel is formed from copper sheet stock with standing seams integrated into the panel rather than applied separately, resulting in a cleaner seam line and a more rigid panel that holds its geometry over decades of thermal expansion and contraction.
Not sure whether standing seam or curved is right for your home? Send me a photo and I'll give you my honest recommendation.

Installation
The Standing Seam Copper Chimney Cap installs one of two ways depending on your chimney. Crown-sit places the cap directly on the chimney crown — no masonry work required. Side-mount uses a drip edge detail fastened through the side of the chimney masonry for a more permanent attachment. No pitch-matching, no friction-dependent flue clamps. The cap fastens to the chimney and stays put.
Material Options
16oz Copper — warm penny tone new, weathering through browns to a natural patina over years. The most durable and visually distinctive option. Riveted construction with copper rivets and solid brass mandrels.
Kynar-Coated Aluminum — factory-applied PVDF coating that holds color without fading, chalking, or peeling. Available in a wide range of Kynar colors including black, copper tone, bronze, and more. Riveted construction with stainless steel color-match rivets. A long-lasting, low-maintenance option for any color palette.
Galvalume — zinc-aluminum alloy coating over steel. Strong corrosion resistance at an accessible price point. Mill-finish appearance. Riveted construction with stainless steel color-match rivets.
About Archaic Metal
I've been fabricating custom architectural sheet metal in South Jersey since 1994 — 32 years working copper, Kynar aluminum, Galvalume, and stainless steel by hand. Every cap that leaves my shop I built myself. If you have questions about your chimney or which cap is the right fit, message me or call.
