The biggest enemy of your chimney system whether it’s spring, summer, fall, or winter is water. Precipitation can wreak havoc on an uncapped chimney, but rainwater is not the only reason to cap your chimney. At Hudson Chimney we know that every chimney flue needs a cap and here are the seven biggest reasons why.
1. Caps Keep Water Out
Chimney caps are designed to keep water out of the chimney flue, preventing serious water damage and danger. No matter what brand or style you buy, it should have a metal roof on it which prevents water from falling into the chimney. The water runs off the chimney cap and onto the crown below. From the crown, water drips down to the flashing and roof.
2. Caps Keep Animals Out
Especially during spring, but also year-round, chimney caps keep animals out of the chimney system. Any critter that can make it onto the roof can make it into the chimney opening if it isn’t properly capped. If they climb back out on their own, they leave behind nesting materials, droppings, and other debris that need to be removed. Some of these animals can obstruct the chimney flue, others suffocate and die inside the system, and some, like the chimney swift, are protected under federal law and cannot even be removed from the chimney system or the home. The best way to prevent animals from gaining access to the chimney is to keep it capped.
3. Caps Keep Debris Out
During stormy periods, winds and rain may carry debris into your chimney flue, leading to obstruction, fire hazards, and even odors as these materials decompose over time.
4. Caps Keep Wind Out
In our area of Jacksonville, Florida, especially this time of year, we experience tropical weather producing high winds. At Hudson Chimney we sell and install special models of chimney caps which deflect wind to prevent damage and stop drafts from entering your chimney.
5. Caps Keep Sparks In
While your fireplace is in use, your chimney vents heat, gases, and sparks. Some of these sparks may be ignited and carried up through the flue and out while still ignited. These sparks can ignite fires on your roof and even on your yard near your house. The metal mesh on your chimney cap stops these sparks and puts them directly back into your flue and down into your fireplace.
6. Caps Protect the Liner
You chimney cap doesn’t just prevent damage to your chimney system caused by water, weather, and animals. The cap will prolong the life of your chimney liner overall by protecting it completely. Whether your liner is a clay tile, stainless steel, or another type of liner, the cap will protect it year-round.
7. Caps Can Double as Dampers
If you choose a top mount damper, it can double as a cap, closing the system from the top-down with an airtight seal. This type of cap/damper mechanism saves our customers money, provides 100 percent protection, and is long-lasting.
