Chimney Cap Installation in Rochester, NY
For chimney cap installation in Rochester, NY, Rochester Premier Chimney Sweep fits a Hy-C stainless steel cap, measured to your flue, that keeps out rain, squirrels and flying embers. It is the cheapest insurance on the house.
A cap is the lid on a growler: cheap, and it keeps out everything that should not get in. Without one, a Rochester chimney gets rain, snow, leaves, birds, squirrels and the odd raccoon right down the flue. Water rusts the damper and soaks the smoke chamber. Animals build nests that block the smoke. And a nest plus a spark is how some chimney fires start. A good stainless cap fixes all of that for a few hundred dollars, and it comes off easily when it is time for the yearly sweep. Our crew usually fits one in 45 minutes.
Chimney Cap Types and Options
One cap per flue, picked for the size of the opening and what is getting in
Single Flue Stainless Caps
A Hy-C stainless cap sized to the flue tile and clamped on. It carries a lifetime guarantee, and the mounting system holds in the gusty wind that comes off Lake Ontario in November.
Multi-Flue Caps
Two or three flues in one chimney get one wide cap that covers the whole top. It keeps rain off the crown and stops animals from getting in through the gap between flues.
Top-Mount Dampers
A top-mount damper is a cap with a spring-loaded door that seals the flue tight. It replaces the old rusty damper inside the firebox and can cut air loss by as much as 90 percent. It also has a lifetime warranty.
Spark Arrestor Mesh
The screen around a cap stops embers from landing on a shingle roof and keeps out birds. We choose a mesh opening small enough for sparks but wide enough that soot does not clog it.

About one in five chimneys we open has a cap that is missing, rusted through or the wrong size. Those are the ones with the nests. Last spring a Greece homeowner called about a smell, and the flue held a bird's nest as big as a basketball. Ron, our owner, has put caps on Rochester chimneys for 24 years, and he still climbs every roof he quotes.
Do I Need a Chimney Cap?
Yes. A chimney cap keeps rain, snow, birds and animals out of the flue and stops embers from reaching the roof. Without one, water can rust the damper, crack the flue tile and soak the smoke chamber. It is one of the least expensive parts of a chimney and prevents some of the costliest repairs.
Rain, Snow and Rust
Rochester gets about 100 inches of lake-effect snow a year, and a flue without a cap is an open funnel. Melt water runs down, rusts the damper and stains the firebox. Over a few winters it gets behind the clay tile and freezes. The cap is the first line of defense against all of it.
Birds, Squirrels and Raccoons
Animals love a warm, dry shaft. A nest on the smoke shelf can block the flue completely. If you hear scratching or flapping, call us before you light a fire. We clear the blockage on a chimney sweep visit and fit a cap so it does not happen again.
Sparks and Roof Fires
Embers can float out of an open flue and land on dry leaves or an old shingle roof. The mesh on a stainless cap catches them. It also keeps wet leaves from stacking up inside, which would otherwise turn into a fire hazard of its own.
Top-Mount Dampers and Energy Savings
If your fireplace is cold when you are not using it, the old damper is probably the reason. Old steel dampers rust and warp, so they never quite close. A top-mount damper seals at the top of the flue instead, with a pull chain you reach from the fireplace. The maker says a top-mount damper can cut air loss by as much as 90 percent. We would call it the easiest way to stop heating the sky.
A new cap often goes together with a chimney liner installation or a chimney crown repair. We cap chimneys from Irondequoit to Webster.
Questions we hear
Chimney Cap FAQs
How long does a stainless chimney cap last?
A stainless steel cap lasts decades, and ours carry a lifetime guarantee from the maker. Cheap painted steel caps rust through in a few winters. We use stainless because it holds up to road salt in the air, lake wind and years of wet snow.
Can I put a cap on myself?
You can, but a poorly sized cap can fall off in a storm or choke the draft. Climbing a roof in winter is the bigger risk. We measure the flue, clamp the cap and make sure it lifts off easily when the sweep needs to get in.
Will a cap stop birds and squirrels?
Yes, when it is the right size. A snug stainless cap with mesh keeps birds, squirrels and raccoons out. If an animal is already inside, we remove it carefully before we cap the flue, so nothing is trapped and the nest is cleared.
What does a top-mount damper do?
It seals the top of the flue with a spring-loaded door you open from the fireplace with a chain. That stops cold air coming down and warm air going up when you are not burning. Ours carry a lifetime warranty. It replaces the rusty damper in the throat.

What Rochester Customers Say
We had a brown stain by the chimney every spring and two roofers blamed the shingles. Ron went up, took pictures of the crown and showed me the crack. New crown, dry ceiling, and he mentioned two cracked bricks before I asked.
Karen L.Crown repair · Irondequoit Bought a 1940s house in Brighton and the inspector said the chimney needed a closer look. They sent a camera down the flue the next week and gave us a report the bank wanted. We closed on schedule.
Matt & Priya S.Camera inspection · Brighton Our wood stove would not draw. They fitted a stainless liner and a new cap in one day, showed me how to burn it and haven't left a speck of soot on the carpet. First winter with no smoky smell.
