The flat metal pan on top of your chimney chase is all that stands between rain and the framing below. When it rusts or ponds water, we replace it with a custom-fit cover that sheds water properly.
The chase cover is the broad metal pan closing off a framed chimney chase up top, with the flue passing through its center. Builders typically installed galvanized covers, and in south Miami-Dade those have a short life: salt-touched air eats through the zinc coating, rust blooms from the center outward, and the flat pan begins ponding water after each afternoon storm. Once the metal perforates, water dumps directly into the chase, drenching framing and, in time, the ceiling underneath. The rust streaks running down your siding are the early warning.
Failed covers get remade in stainless or heavy-gauge aluminum, fabricated to your chase's exact dimensions. Every cover gets a cross-break — a slight ridge formed across the center — so water runs off to the edges instead of ponding, plus a hemmed drip edge that carries runoff past the siding and a storm collar sealing the flue penetration. Measured and fitted properly, the new cover ends the leak at its source rather than chasing stains inside the house. Free written estimates, upfront pricing, and no hidden fees on every replacement.
Covers made to your chase's true measurements, with the right skirt depth and flue opening placement — not a stock pan forced to fit.
Materials chosen for coastal South Florida, where galvanized steel rusts out years ahead of schedule.
A formed ridge sheds water to the edges, and a hemmed drip edge keeps runoff off the siding below.
The flue penetration is collared and sealed so storm-driven rain never slips in around the pipe.
We take exact dimensions of the chase top, flue position, and skirt depth so the new cover fits the first time.
The replacement is formed in stainless or aluminum with a cross-break, hemmed edges, and the correct flue opening.
The old cover comes off, damage underneath gets checked, and the new cover is fastened, collared, and sealed.

The cover is the flat pan sealing the chase's entire upper surface; the cap is the little hood perched over the flue opening. They work as a pair — the cover defends the structure from water, while the cap keeps weather, wildlife, and litter from dropping into the flue. We handle both.
Stainless steel is the most corrosion-resistant option we install and the one we recommend this close to the bay. Heavy-gauge aluminum also performs well here and won't rust, though it's a softer metal. What we don't recommend is another galvanized pan, because the coastal air that killed the first one hasn't gone anywhere.
Coatings buy a little time on surface rust, but once a cover pits or holds standing water, corrosion is working from both sides of the metal. Replacement costs less than repairing the rotted framing that a failed cover eventually causes.
