Types of Chimney Caps

Chimney caps are not only differentiated by their design, but also by the material they’re made from. Key materials include stainless steel, copper, and galvanized steel, each offering unique advantages and aesthetics.

Various types of chimney caps

Stainless Steel

Known for their durability and resistance to rust, stainless steel caps are an excellent choice for long-term protection. They effectively keep out rain, snow, animals, and debris from your chimney, while also preventing sparks from escaping. Since stainless steel doesn’t rust, these caps maintain their appearance over time, making them a cost-effective and low-maintenance choice.

Galvanized Steel

These caps are often more affordable than their stainless steel or copper counterparts. Galvanized steel is steel that has been coated in a layer of zinc to help resist corrosion. While they can effectively keep out rain, snow, debris, and animals, they aren’t as resistant to rust as stainless steel or copper, and thus may need to be replaced more frequently.


Copper chimney caps bring a distinct, elegant appearance to your home’s exterior. Beyond aesthetics, copper is a durable material that naturally resists corrosion. Although copper chimney caps may patina over time, this process often enhances their beauty, giving your chimney a classic, weathered look.

Cast Iron

Cast iron caps are incredibly durable and robust, with a unique aesthetic that can add an antique or rustic look to your home. However, they require a certain level of maintenance to prevent rusting, and they’re heavier than other types, which may make installation more challenging.


Aluminum caps are lightweight and also resistant to rust. They’re a good choice for chimneys that need a lighter cap due to structural issues, but they may not be as durable or robust as stainless steel or copper caps.

Our Process

Chimney Cap Installation Process

Installing or replacing a chimney cap is an important task that ensures the safety and longevity of your chimney system. This process involves selecting the appropriate cap, preparing the chimney, and then securing the cap in place. Below is a comprehensive step-by-step guide to help you understand what the installation or replacement process entails.

  1. Measure the Chimney: Before you purchase a new cap, it’s essential to take accurate measurements of your chimney’s exterior or flue. You’ll need to measure the length and width, and in the case of a round flue, the diameter. It’s also a good idea to take note of the material and construction of your chimney, as different chimney types may require different types of caps.
  2. Select the Right Cap: With your measurements in hand, select the appropriate cap. The material (stainless steel, copper, etc.) will depend on your personal preferences and budget, while the design will be dictated by your chimney’s construction. For example, if you have multiple flues, you’ll likely need a multi-flue cap.
  3. Prepare the Chimney: Before installing the new cap, ensure your chimney is clean and free of debris. If you’re replacing an old cap, remove it carefully. The area where the cap will sit should be clean and undamaged to ensure a secure fit.
  4. Install the Cap: The method of installation will depend on the type of cap you have chosen. Single-flue caps usually attach directly to the flue, while multi-flue caps and outside mount caps attach to the chimney crown. Follow the manufacturer’s instructions to secure the cap, usually involving tightening screws or clamps. Always ensure the cap is stable and secure.
  5. Check the Installation: Once the cap is installed, do a visual inspection to confirm it’s secure and correctly positioned. The cap should cover the flue completely, and there should be no gaps where animals or debris could enter.
  6. Maintenance: After installation, regular checks and maintenance are vital to keep the chimney cap in good condition. This involves periodic cleaning and checking the cap after severe weather conditions.

Why They Are Important

Benefits of Having a Chimney Cap

A chimney cap serves as a small but vital piece of equipment that can significantly influence the longevity and performance of your chimney. By protecting the interior of your chimney from various elements, it provides numerous benefits that range from enhancing safety to reducing maintenance costs.

The benefits of having a cap on your chimney

Preventing Moisture Damage

One of the primary functions of a cap is to keep rain, snow, and other forms of moisture out of your chimney. This prevents water damage that could deteriorate the flue lining, damper, and other parts of the chimney system, potentially leading to costly repairs.

Blocking Animals and Debris

A chimney cap acts as a barrier against animals like birds and squirrels that may try to nest in the chimney. It also prevents leaves, branches, and other debris from falling into the chimney, which could block the airflow and lead to potential fire hazards or inefficient heating.

Preventing Downdrafts

In windy conditions, a draft can send smoke and fumes from the chimney back into your home. A properly installed cap can deflect these downdrafts, ensuring that smoke and gasses are vented properly.

Preventing Escaping Sparks

Chimney caps, particularly those with spark arrestors or mesh siding, can prevent sparks or embers from your fire from escaping and potentially starting a roof fire.

Saving Energy

Caps can prevent warm air from escaping your home when the fireplace is not in use. Conversely, it can also prevent cold outside air from entering your home, thus improving energy efficiency.

Enhancing Aesthetics

Beyond the practical benefits, a chimney cap can also enhance the look of your home. With a variety of styles and finishes available, you can find a cap that complements your home’s exterior design.

Preventing Odor

When the fireplace is not in use, especially during damp conditions, the creosote and other residues in the chimney can produce a foul odor. A cap can limit the amount of moisture entering and thus help minimize these unpleasant odors.
