The chimney cap is a vital detail to remember when putting the finishing touches on a new home or checking the winterizing checklist for an older home. If you need to cap an existing chimney or select the right one for new building, making sure your house has a dependable chimney cap in place now will save you time and money in the future. Any chimney cap you purchase should come with some kind of quality guarantee, whether it’s for three years or for the rest of your life. If the manufacturer is unable to stand behind their product for an extended period of time, this is a big red flag. Examine the competition as quickly as your browser would allow.

Stainless steel, black galvanised steel, and copper are the most common materials for chimney caps. The flue’s outside width and length are often used to calculate the height of the chimney cap. Since flue dimensions can range from six to 22 inches, precise measurements must be taken before ordering. Multi-flue chimney caps are usually available to address the problem of covering odd-sized, numerous, or unlined flues.
Not only do chimney caps keep unwanted items like birds, snow, and rain out of your chimney, but they also keep flying sparks and ashes off your roof.
You can also choose a spark screen with a tighter mesh, though it’s not needed in all states except California. California, and probably other states, have tighter spark arrestor codes that require 5/8-inch mesh chimney cap spark screens rather than the more common 34-inch mesh panel mesh.
If you’ve been having issues with chimney backdraft, there are chimney caps on the market that can help you solve the problem. Vacu Stack wind caps, for example, not only help draw air out of the chimney by raising the upward draught, but they also help avoid downdrafts and wind-related back-puffing. The Exhausto Fan, which comes with a bird screen, a fan speed regulator, and a pre-wired junction box, is another choice for most chimney draught problems. The system uses almost the same amount of energy as a standard light bulb in terms of energy consumption. Installing a flue stretcher chimney cap is another way to reduce chimney backdraft issues. These stainless steel and copper flue stretcher chimney tops help minimise downdrafts and increase upward air flow by extending the height of chimney flues by up to two feet.
Decorative chimney caps come in a wide range of sizes and shapes to complement the exterior of your house. Copper chimney pots are one way to add visual appeal to a roof while also reducing chimney backdraft issues. Prices could range between $800 and $850. Copper chimney pots in octagon, square, and cone shapes, all about three feet tall, are among the attractive styles.
European copper chimney pots by Jack Arnold are at the high end of the price spectrum, ranging from $1300 to $1800. These antique-looking chimney caps, on the other hand, would certainly improve the architecture of the house and the overall aesthetics of the property for people with palatial homes and a large budget.
