The Best Chimney Caps in the Lowcountry
A chimney without a proper cap is an open invitation for rain, for birds and squirrels, and for embers with nowhere else to go. BB Roofing installs and repairs chimney caps across the Lowcountry. Call 843-379-3033 for a free estimate.
What an Open Chimney Actually Costs You
Water intrusion is the most expensive problem an uncapped chimney causes, and it’s rarely obvious until the damage is already inside the wall. Rain running straight down an open flue soaks the smoke chamber and damper, and over enough seasons that moisture works into the surrounding masonry and framing. It’s a slow, hidden version of the same water damage a missing shingle causes on the main roof. A cap with the right flashing at the base stops that path before it starts.
The other problem is wildlife. An open flue looks like a ready-made nest site to squirrels, birds, and raccoons, and once something gets in, it doesn’t always find its way back out. Mesh-sided caps block entry without blocking draft, which matters, since a cap that restricts airflow too much can cause its own problems with how the fireplace or furnace vents.
Getting the Fit and Material Right
Chimney caps aren’t one-size-fits-all. Multi-flue chimneys need a cap sized and vented for each flue individually, not a single oversized cover that chokes draft on one side to cover another. We measure and match the cap to the actual flue dimensions rather than reaching for whatever’s closest on the shelf.
Material matters more here than on most parts of the roof, because a chimney cap sits exposed at the highest point of the house, taking the full brunt of salt air. Stainless steel and copper hold up to that coastal exposure far better than galvanized steel, which can start showing rust within a few years this close to the water. We spec material based on how long you want the cap to actually last, not just the lowest price point.

Chimney Caps FAQs
Do I need a cap if I don’t use my fireplace often?
Yes, the cap’s water and pest protection matters whether or not the fireplace ever gets used. An unused flue with no cap is often the one that goes unnoticed longest.
What’s the difference between a cap and a spark arrestor?
A cap covers the flue opening against water and animals; a spark arrestor is the mesh screening built into a proper cap that also stops embers from landing on the roof. A quality cap does both jobs at once.
How long does a chimney cap installation take?
Most single-flue installations take under an hour once we’re on the roof; multi-flue chimneys or full replacement of damaged flashing take longer.
Can a chimney cap fix a smoky fireplace?
Sometimes. A damaged or missing cap can actually cause downdraft problems, and correcting the cap resolves it. Other draft issues need a separate look at the flue itself.
