Does one need a chimney cap or not? Does the rain bother the chimney or
affect the soot? If there is an inch of rain that means there is an inch
or rain in the chimney, where did it go?
When I run the wood stove I can hear the rain sizzling when it hits the
stove pipe in the chimney. Why are some chimneys capped and others not?
Some I guess have problems with squirrels or birds nesting in there and
I can see a cap in that case.

A cap keeps crap out as well as rain, but the biggest advantage may be
improved draft. When your furnace kicks on, for example, it takes a
few minutes for the chimney to warm up and start drawing efficiently.
The cap helps it warm up faster. That contributes to fuel savings. A
cap also helps prevent wind from blowing DOWN the chimney.
I have at several locations had racoons, birds, pigeons all alive at
the bottom, I pulled out the birds alive and let them go, the coon I
smoked out, birds sit up there in winter with Ng for heat, die and
fall in. A racoon can block a chimney. Unless its steel lined water
will help shorten chimneys life from getting motar wet then freezing
at night and eventualy brick falls apart blocking draft. Embers from
a hot fire Ive seen come out my chimney. A cap has many advantages
Never had a cap on mine until first a bird, then a squirrel go into it.
Both got in, could not get out and the cleanout is on the inside, not
The cap keep things clear that way, but in my case it has a downside too. I
have a wood burning stove. If the fire is on the modest size, I get
condensation on the cap dripping down the chimney and enough to come out hte
We never had a cap. Then we discovered a raccoon living in the chimney.
My husband installed the cap. He waited until the raccoon left during the
evening hours and then installed it. Good thing we only have a one story
No cap here, but I have a cat.
Bob (the cat) has not been outside since he was rescued as a feral kitten
eight years ago.
One night, not long ago, as I was in bed reading, I heard a commotion in the
washroom. Putting on my slippers, I investigated and found Bob with his
front paw holding down an itty-bitty chimney swift.
He hadn't hurt the bird, just caught it.
He looked at me, grinned, and meowed.
I retrieved the bird, opened the door, and released it. The bird looked okay
as it flew away into the night.
Had he been wearing a vest, he would have popped the buttons! He was so
proud, he wasn't fit to be around the rest of the night. He kept telling me,
in emphatic cat talk, about his most excellent adventure!
Kind of endearing, really.
So, if it comes to a vote on the efficacy of chimney caps, I'm pretty sure I
know where Bob would come down.
Caps are necessary. If rainwater gets into the flue, it can cause problems
with the flue. In my case, where there is no cap and are no trees nearby,
sometimes the rain goes all the way down to the damper. It makes the house
smell like a camp fire for a few days.
Some chimneys are capped because those owners or installers knew it should
Just put one on. It serves several important & convenient purposes. A
plain black 13"x13" will cost you 32 bucks (online info) at orange Borg.
It was $23 in mid June when I got one. That's a 23% increase in 3+
months. Must be the added fuel cost for shipping weight, ehhh? Say it
weighs maybe 6 lbs. That's a buck a pound increase. Bundle of shingles
about 70lbs. Used to be about $15. Wonder why they are not $85 a bundle
now. Last I saw the bundle that used to be $15 is now about 18.
