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 Hip & Ridge Cap
A hip and ridge chimney cap is built to follow the roofline — four sloped panels that rise to a central ridge, matching the geometry of a hipped or gabled chimney saddle. If your chimney has an angled roof rather than a flat crown, this is the cap that fits it correctly. I fabricate every H&R cap to your exact chimney dimensions and pitch from 18×18 up to 60×120, in my shop in Berlin, NJ.
Every panel is cut, bent, 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 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.

Roof Pitch
Available in 4:12, 6:12, 8:12, 10:12, and 12:12 to match your existing roof or chimney saddle. The calculator above adjusts pricing automatically for pitch — steeper pitch means longer "rafter" length = more material. If you're not sure of your pitch, you can use a pitch gauge app on your phone to check.

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.
