Custom 20oz Concave Copper Chimney Cap Built From Scratch

Most chimney caps are mass-produced, generic, and built to a price point - not a standard. When a client needs something that actually fits their chimney perfectly and looks the part, that's where custom fabrication comes in. This 20oz concave copper chimney cap is a good example of what that process looks like when it's done right.

We built this one entirely in-house, start to finish. The concave profile on the hood gives it that distinctive, high-end look you don't get from anything off a shelf. The copper mesh screen runs all the way around the base, keeping debris and animals out while still allowing proper airflow through the flue. Every seam, every fastener, every corner was handled with care before it ever left the shop.

Copper is one of the best materials you can use for a chimney cap. It holds up against weather, resists corrosion, and actually gets better looking over time as it develops a natural patina. Using 20oz copper means this cap has real weight and thickness to it - not the thin stuff that dents and warps after a few seasons on a rooftop.

The concave design isn't just about looks either. That curved hood profile helps direct water away from the flue opening more effectively than a flat top. It's a detail that serves a purpose. That's the kind of thinking that goes into every piece we fabricate - form and function working together, not competing with each other.

This cap shipped out ready to install, which is how we handle all our custom metalwork. The client doesn't have to deal with anything on their end except getting it up on the roof. If you've got a chimney that needs something built to spec, this is exactly the kind of work we do.
