Also called a chimney topper, chimney rain cap, chimney cover, chimney shroud, or chimney surround — whatever you call it, this one is built to last.
Top Mount Cap Measuring — Add 6" to the length and width of where you want the screen to sit on the chimney top. Top Mount vs Side Mount Guide →
Available in copper, stainless steel chimney cap, Kynar aluminum, and Galvalume. Stainless steel chimney caps and stainless chimney covers are built to the same spec and dimensions as every other material — contact me to order.
The Straight Panel Cap
Where the curved panel cap has a convex flare, the straight panel reads architectural and restrained — flat standing seam panels rising to a clean hip roof. Clean lines, precise geometry, no ornament. It works on traditional homes, transitional designs, and anywhere the roofline calls for structure without decoration. If the curved panel is classic, the straight panel is precise.
Every cap is hand-fabricated to your exact chimney dimensions in my shop in Berlin, NJ. The panels, the hip roof pitch, the screen opening, and the base flange are all cut, formed, and assembled by hand — the same way it's been done in my shop since 1994.
What It Actually Does
A properly fitted cap does four things a hardware store cover doesn't: it protects the entire chimney crown (not just the flue tile opening), it blocks animal entry with a heavy stainless steel spark screen, it reduces wind-driven downdraft, and it contains embers from wood-burning fireplaces. The full-perimeter flange sits on the crown — crown repair runs $500–$3,000, and a cap that covers it correctly prevents all of it.

Cross-Brake Removable Lid
Every cap includes a cross-brake structural lid standard — a single-piece lid with a built-in cross-brace for rigidity. Secured with a ¼-20 stove bolt threading into a stainless steel rivnut insert — brass bolt on copper caps, stainless steel on all other materials. Removes with a screwdriver for chimney sweeping or flue access. Standard on all materials and all sizes.

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

About Archaic Metal
I've been fabricating custom architectural sheet metal in South Jersey since 1994 — copper, Kynar aluminum, Galvalume, and stainless steel, all by hand. Every cap that leaves this shop I built myself. If you have questions about your chimney or which cap is right for it, message me or call. I personally review every order before fabrication starts — you won't be left guessing.
