From Fairmount's century-old rooflines to the prefab chimneys of Ridglea and Tanglewood, Fort Worth's hail and heat take a toll on chase covers — we fix and replace them right.
Drive through Fort Worth and you'll see two very different chimney stories. In Fairmount and Arlington Heights, early-1900s masonry homes still carry brick chimneys with mortar crowns. But push out toward Ridglea, Tanglewood, the TCU area, and the newer subdivisions ringing the city, and most homes were built with framed, prefabricated chimney chases capped by a thin sheet-metal chase cover. That metal cap is small, but it's doing a big job — and in Fort Worth's hail, wind, and heat, it fails faster than most homeowners expect.
The chase cover is the flat or slightly pitched metal panel sitting on top of the framed chase — the boxed-in structure that houses the metal flue pipe on a prefab fireplace system. It's easy to confuse with a chimney cap, but they're not the same thing. A cap covers the flue opening; the chase cover seals the entire top of the enclosure, keeping rain and pests out of the framing itself. When it fails, water doesn't just drip into the firebox — it can soak into the wood chase structure underneath.
Most homeowners notice the problem on the siding before they ever look at the roofline. Rust-colored streaks running down the chase enclosure or exterior wall are the classic tell — galvanized coating breaking down and bleeding down the metal every time it rains. Ponding water on top of the cover, a cover that's visibly warped or oil-canning in the sun, or gaps opening at the seams are all signs it's time for a look.
Fort Worth doesn't do mild weather. Spring and early summer bring hail that can dent even quality metal, and the wind that comes with those same storm systems works at loose seams until they lift. Add in the area's clay soil, which expands and contracts with every wet-dry cycle and shifts foundations just enough to stress rooflines, plus the freeze-thaw swings of a Texas winter, and you've got a recipe for a chase cover that ages faster than it should. This shows up differently by neighborhood: in Fairmount and Near Southside, older masonry chimneys deal with mortar and crown issues, but the prefab metal chimneys common in Ridglea, Tanglewood, the TCU area, and Fort Worth's newer subdivisions are the ones where a failing chase cover is the recurring headache. If your home was built from the 1970s onward with a factory fireplace system, there's a good chance a metal chase cover sits on top of it right now, quietly taking hail hits and baking in the summer sun.
We inspect and replace chase covers across Fort Worth, from Ridglea to the TCU area.
(214) 225-8874Most factory-installed chase covers are galvanized steel, which is fine for a while but has a coating that eventually wears through, especially with the freeze-thaw and hail cycles Fort Worth sees year after year. Once that coating goes, rust follows — and it doesn't stop. Stainless steel costs more upfront but doesn't rust, holds up better against hail dents, and typically outlasts the galvanized option by decades. For homeowners in Tanglewood or Arlington Heights tired of replacing the same rusted cover every few years, switching to stainless during a replacement is usually the better long-term move. This pairs well with a broader chimney inspection to check the flue and flashing at the same time, and it's a natural add-on if you're already having flashing repaired where the chase meets the roofline.
We won't invent a number here, because the honest answer is that it depends on a handful of real factors. The size of your chase opening matters most — larger prefab chimneys need more material and a custom fit. Material choice is next: galvanized is the lower-cost option, stainless is the durable upgrade. Roof pitch and how accessible the chase is also factor in, since a steep roofline over a two-story home in Ridglea takes more time and safety setup than a single-story ranch. Finally, if hail or long-term rust has already damaged the underlying wood chase, that repair gets addressed alongside the cover itself.

If your fireplace was a factory-built, prefab unit rather than a full masonry chimney, you almost certainly have a chase cover on top of the framed enclosure, with a separate cap over the flue pipe itself. This setup is common in Fort Worth homes built from the 1970s onward, especially in suburban areas like Ridglea and Tanglewood. If you're unsure, we can take a look and tell you exactly what's up there.
Standard galvanized chase covers have a protective coating that wears down over time, and Fort Worth's hail, heat, and freeze-thaw cycles speed that process along. Once the coating breaks down, rust starts and doesn't stop on its own. Switching to a stainless steel cover during replacement usually solves the recurring rust problem for good.
Yes, and it's more common than people expect. Once seams lift or rust eats through the metal, water gets into the wood-framed chase structure, and in a wet Fort Worth spring that can lead to rot you can't see from the ground. Catching rust stains or ponding early keeps it to a cover replacement rather than a structural repair.
Most of the historic masonry homes in Fairmount and Arlington Heights have full brick chimneys with mortar crowns rather than framed chases, so this specific issue is less common there. It's mainly a concern for the mid-century and newer prefab chimneys found throughout Fort Worth's suburban neighborhoods. If you're not sure which type you have, we can confirm during an inspection.
We work throughout Fort Worth and the surrounding DFW area seven days a week, including Sundays, so getting an inspection scheduled usually isn't a long wait. Call (214) 225-8874 or request a Free Online Quote and we'll get your chase cover looked at before the next round of storms rolls through.
