Where a flat cap or standard peaked cap gives you a utilitarian profile, the arch gives you something that actually looks intentional. It's the right cap for chimneys on buildings with architectural character — historic homes, custom builds, churches, commercial masonry — anywhere the roofline deserves more than a box with a lid.\u003c\/p\u003e\n\n\u003cp\u003eI fabricate every arched cap to your exact chimney dimensions by hand, here in Berlin, NJ — copper sheet cut and curved to shape, fitted with expanded copper screen, assembled with stainless steel rivets. Sizes from 20×24 up to 36×120 are priced on the calculator below. Wider than 36″? Call or text me directly — those are built-to-spec and quoted individually.\u003c\/p\u003e\n\n\u003ch3\u003eWhat It Actually Does\u003c\/h3\u003e\n\n\u003cp\u003eA 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.\u003c\/p\u003e\n\n\u003cp\u003e\u003ca href=\"https:\/\/archaicmetal.net\/blogs\/resources\/what-is-chimney-crown\" title=\"What Is a Chimney Crown and Why Does It Crack\" rel=\"noopener\" target=\"_blank\"\u003eWhat is a chimney crown — and why yours may already be cracking →\u003c\/a\u003e\u003c\/p\u003e\n\n\u003ch3\u003eArched Cap Construction\u003c\/h3\u003e\n\n\u003cp\u003eThe arch is fabricated from 16oz copper sheet, rolled and shaped to a true curve — not a bent angle or a folded peak, but a smooth radius that holds its form under load. The fascia wraps the full perimeter of the chimney crown. The arch roof vents on the two short ends only — expanded copper screen is set into each end panel, with screen height at 75% of the width dimension. This gives you solid protection against wind-driven rain and debris from the long sides while maintaining full ventilation through the ends.\u003c\/p\u003e\n\n\u003cp\u003eEvery cap that leaves this shop I built myself.
