Despite being simple in nature, a chimney cap is one of the most integral parts of the chimney system. Typically, you’ll pay around $300 to install or repair a chimney cap. But the price will fluctuate based on the type of repair, the material used, and the dimensions of the chimney cap.

How Much Does a Chimney Cap Cost by Type?

Realistically, a broken or damaged chimney cap often isn’t worth it to repair. The price of materials needed and labor typically comes out to be the same price as replacing it, putting the price for both repair and replacement at around $350.

How Much Does a Chimney Cap Cost by Style?

You can select from three types of chimney cap materials—galvanized steel, stainless steel, and copper.

Galvanized Steel

Galvanized steel has the lowest durability out of the three, but also comes with the lowest cost. A galvanized steel chimney cap will cost anywhere from $15 to $200, depending on the gauge of the steel and the size.

Stainless Steel

Stainless steel chimney caps are the next level up when it comes to strength and durability. These chimney caps usually last longer than their galvanized counterparts. Expect to pay around $50 to $500 for a stainless steel chimney cap.

Copper

Copper is considered the top tier of chimney caps. This type of cap has one of the most pleasant aesthetics while also standing up to debris, rain, snow, and critters. When shopping for a copper chimney cap, expect to pay around $150 to $900, depending on size and shape.

Chimney Cap Cost Breakdown

Beyond material and type of repair, a few details go into the chimney cap replacement process. You should think about cleaning the area before work begins and consider whether you want a custom cap or a prefabricated option.

Labor

Typically, labor makes up about 50% of the project's total cost. However, it's likely to take up more, as most homeowners often buy the chimney cap separately before a chimney repair company installs it.

Custom vs. Prefabricated Chimney Caps

Custom chimney caps have gained popularity in recent years. They allow you to choose more stylish options that wouldn’t necessarily be available from prefabricated options.

Custom chimney caps can range anywhere from $200 to $1,000, depending on the shape, colors, and type of material requested.

Prep Work

You should ideally have a clear spot for the chimney cap to go. Your best bet is to hire a chimney sweep to handle the job. Chimney sweeps cost anywhere from $130 to $380—and you can also ask if they install chimney caps.

How Much Does a Chimney Cap Cost to Replace or Repair Yourself?

If you’re familiar with a toolbox and you have a relatively flat roof (a pitch of 4/12 or under), you should be good to install the chimney cap yourself. In addition to the chimney cap of your choice, you'll need a ladder and a screwdriver. You'll save around $150 to DIY.

You may consider sealing your chimney while you’re installing the cap. The cost of sealing and capping a chimney is around $575 on average.

Remember, any time you're up on a ladder or your roof, you're taking some risk. That's why it may be better to call a professional to handle the job.

FAQs About Chimney Caps

Is a chimney cap necessary?

There are plenty of reasons to install a chimney cap. Not only does it help keep away wild animals such as birds and squirrels, but it also serves as protection from debris entering the rest of the system.

Do chimney caps keep rain and snow out?

Chimney caps have a solid top, but perforated sides so smoke can exit safely. If rain or snow falls downward, chimney caps can protect the chimney’s interior. Just note that if rain or snow blows in sideways, there’s a higher likelihood it will enter the chimney.

How long does a chimney cap last?

Chimney caps will last anywhere from three to 25 years, depending on the material and climate.

How tall are chimney caps typically?

The general rule of thumb for chimney caps is to sit at least 5 inches off the top of the flue.
