Choosing the Best Chimney Cap to Prevent Water Leaks

One of your best defenses against water penetration and animal invasions of your chimney, a chimney cap sits on top of your chimney’s opening. With several different types of chimney caps available, how do you know which cap is the right fit for the flue of your chimney? At Weststar Chimney Sweeps, we are experienced with fitting all types of chimney caps, even customized caps, and we know the importance of proper installation. We would like to tell you a bit about the different kinds of chimney caps and what you should know about selecting the right kind for your chimney to prevent damaging water leaks.


The main thing to consider when deciding which chimney cap is right for your chimney is the shape of your flue. Chimney caps come in different shapes to fit each type of flue. These shapes include:


Whether you have a clay, masonry, or metal flue, you can find a round chimney cap that can either attach the the outside of the flue or slip inside the flue. Round chimney caps are made from an assortment of materials including copper, stainless steel, and galvanized steel. Some round flue liners require chimney caps that must be inserted inside the chimney flue, such as round flexible flue liners and round solid pack flue liners.


The most commonly shaped flue, square and rectangular chimney caps can be attached to the flue, or, if you have a chimney crown, there are chimney caps in these sizes that can attach to the crown. Made from the same metals as the round chimney caps, the Chimney Safety Institute of America (CSIA) recommends you choose a chimney cap constructed from a sturdy, durable, and rust- and corrosion-resistant material to ensure a long-lasting cap. For chimney caps that attach to a chimney crown, you will need to choose from top mounted chimney caps.


Unless you have a custom-shaped oval chimney cap made for you by our technicians at Weststar Chimney Sweeps, you will need to look at rectangular shaped chimney caps that will cover the exterior of your flue.. When you look inside this type of cap, you can see how the corner tabs or interior ledges will accommodate oval flues.

There are other considerations other than preventing water leaks to think about when choosing a chimney cap. These include:


To prevent animals from entering your chimney to take up a new residence and to keep sparks from flying out of your chimney and possibly starting a fire, your chimney cap should be equipped with wire mesh sides. Be sure the mesh openings are between ¾ to ½ inches in size to keep animals out, to contain large pieces of hot debris and ashes, and to allow toxic gases to escape.


You can now find top sealing chimney caps that do double duty as a protective cap and as a damper. Perfect for new home constructions and for older chimneys in need of numerous repairs, the damper is located on the cap. When it is sealed closed, the air loss from your home is reduced by 90%. When the damper is opened, the wire mesh on the chimney cap protects your chimney from invading animals and prevents stray sparks from exiting.

The Luck of the Chimney Sweep

At Weststar Chimney Sweeps, we are asked why a chimney sweep is considered to be lucky. Many Americans have not heard the legends of the luck of the chimney sweep as they all originated in Europe. In fact, because of these legends, it is considered to be very lucky for the bride and groom in England to see a chimney sweep on their wedding day. If that chimney sweep kisses the bride or shakes the groom’s hand, even more luck is brought to the new marriage. This belief is so popular that English chimney sweeps even rent out their services to appear at weddings to bring luck to the bride and groom’s new life together. Since so many of our customers are curious about these legends, we would like to share the three main stories about why a chimney sweep is considered to be good luck in love and happiness.


The Chimney Sweep who Saved the Life of King William of Britain

The legend of the luck of the chimney sweep began in 1066 in Great Britain. A chimney sweep spotted a runaway carriage heading right for King William of Britain, who was walking quietly down the road. With amazing courage, the chimney sweep rushed to push the wayward carriage out of King William’s path, which saved his life. As a sign of his eternal gratitude towards this lifesaving, brave chimney sweep, King William made a declaration to his people that all chimney sweeps as bringers of good luck. To further show how grateful he was, the king invited the chimney sweep to his daughter’s wedding to bring luck to the bride and groom. Ever since, Europeans believed that chimney sweeps are lucky charms at weddings, which has led to chimney sweep being frequent wedding guests for centuries.

The Chimney Sweep who Saved King George II of England

Another legend featuring a courageous chimney sweep that dates back to the 1700’s, King George II was riding his horse in a procession down a street in London when suddenly, an angry dog appeared before the horse, growled and barked fiercely, and scared the horse. Crazed by fear, the horse bucked and jumped uncontrollably and caused King George II to let go of the reins. Only one man was brave enough to come out to help the king by grabbing the horse and calming the animal down. This man was a local chimney sweep, and, by calming down the horse, he saved the king’s life. To show how grateful he was to this chimney sweep, King George II announced that from this day forward all chimney sweeps should be seen as signs of future success and deserved to be treated with the greatest respect. From then on, English chimney sweeps have been considered as bringers of luck, success, and good fortune.

The Chimney Sweep who Fell from the Roof and Fell in Love

An undated legend that originated in Europe tells the tale of a chimney sweep who was working on a roof and fell. Fortunately, according to Good Luck Symbols, his life was spared because his foot got caught in the gutter; however, he was not completely safe as he was hanging upside down. Fortunately for this chimney sweep, a young woman who lived in the house heard this cries for help and looked out of her window to see him dangling in front of it. Immediately becoming determined to save the life of this chimney sweep, she pulled him inside through the window and led him into safety. This young woman was engaged to be married, but once the chimney sweep composed himself inside, the two instantly fell in love at first sight. She ended her engagement and married the chimney sweep and lived happily ever after. This legend of a chimney sweep’s luck in love spread throughout the continent and the globe and continues to this day.
