Chimney Caps can be both a Necessity and a Luxury
by Joel Sussman
If you’re putting the finishing touches on a new home or reviewing your
winterizing checklist for an older home, an important detail to keep in mind is
the chimney cap. Whether you need to recap an existing chimney or choose
the best one for new construction, you can avoid headaches down the road by
making sure your house has a dependable chimney cap in place now. One
prerequisite of any chimney cap you buy should be that it comes with some
sort of quality guarantee, whether it’s for three years or a lifetime. If the
manufacturer isn’t willing to stand behind their product for any period of time,
then that should be seen as a major red flag. Check out the competition as

Chimney caps are typically available in stainless steel, black galvanized steel,
and copper. The size of the chimney cap is often determined by the outside
width and length of the flue. Since flue dimensions can range from six to 22
inches, it’s necessary to take accurate measurements before ordering. Most
of the time, multi-flue chimney caps can be purchased to solve the challenge
of covering odd-sized, multiple, or unlined flues.

Not only do chimney caps help keep unwanted stuff out of your chimney, like
animals, snow, and rain; but they also play a role in keeping flying sparks and
ashes off your roof. You also have the option of choosing a spark screen with
a more tightly-knit mesh; although with the exception of California, it’s not a
requirement. The state of California, and possibly other areas, have stricter
spark arrestor codes that require chimney cap spark screens to have a 5/8
inch mesh, as opposed to the more standard ¾ inch screen mesh.

If you’ve been encountering chimney backdraft problems, there are chimney
caps on the market that are designed to correct that condition. Vacu Stack
wind caps, for example, not only have the effect of stopping downdrafts and
wind-related back-puffing, but it helps draw air out of the chimney by
increasing the upward draft. Another solution to most chimney draft problems
is the Exhausto Fan, which includes a bird screen, a fan speed control, and a
pre-wired junction box. From an energy consumption standpoint, the device
does not use much more energy than a household light bulb. Another
approach to reducing chimney backdraft problems is by installing a flue
stretcher chimney cap. By extending the height of chimney flues by up to two
feet, these stainless steel and copper flue stretcher chimney tops help reduce
downdrafts and improve upward air flow.

Decorative chimney caps are available in a variety of sizes and shapes to
enhance the outside appearance of your home. One approach to adding
visual interest to a roof, while reducing chimney backdraft problems, is the use
of copper chimney pots. Prices could be in the vicinity of $800 to $850.
Attractive designs include octagon, square, and cone-shaped copper chimney
pots, all of which are approximately three feet tall.

At $1300 to $1800, European copper chimney pots by Jack Arnold are at the
upper end of the price scale. However, for people with palatial homes and a
hefty budget, these antique-looking chimney caps will undoubtedly enhance
the architecture of the house and the overall aesthetics of the property.

So whether you want to spend $59.95 on a basic, stainless steel chimney cap
or $1799.95 on a fancy European-style copper chimney pot, you’ll be
accomplishing a similar set of objectives: keeping wildlife out of your chimney,
adding a “finishing touch” to the look of your chimney, and, in some cases,
controlling chimney backdraft. It all depends on your budget, the design of
your house, and what kind of statement you’d like to make with your chimney
cap.
