Installing a chimney cap costs $300 on average, ranging from $75 to $1,000. The cap runs $35 to $550 depending on material and size. In most cases, you'll pay $100 to $200 for installation.
Without a chimney cap, all you have at the top of the flue is an open hole. If you want to prevent rodents, leaves or precipitation from falling inside, you'll need to install a cap. A wide variety of materials and styles make it easy to get one that looks great with your roof. Keep these factors in mind before you decide.
Replacing a chimney cap averages about $350, which is $50 to $100 more than installing a new one. This relates to the time needed to remove the existing unit.
With an average of $350, it may be less hassle to replace the cap instead of repairing it. Dents and scratches reflect cosmetic damage and don't generally affect the function or safety.
Chimney caps cost $35 to $550. Most products are made of galvanized or stainless steel. Copper runs about $200 to $300 more than other materials. Higher prices usually indicate a better-quality product that will last longer.
With a price range of $35 to $550, there are many cost factors that affect the total for a chimney cover. These include:
Dimensions, with custom sizes costing more
How easy the chimney is to access
Whether you want custom styles or elements
Season, particularly in winter
Other services required, like flue repair
Besides material, size is the largest factor in the total price. For example, you'll pay $35 to $200 for a cap that measures 9" x 9", compared to $150 to $550 for one that's 14" x 37".
Putting on a chimney cap may take less than an hour, but you still have to climb up to your roof to do it. Hiring a pro costs $100 to $200 more than DIY and carries much less risk.

Chimney caps are necessary to keep animals, water and debris from falling in. They also control wind to minimize the risk of a backdraft.
Caps minimize rain and ice accumulation inside the chimney. They must remain partially open to allow exhaust to escape. As such, they do not provide a completely waterproof barrier.
Chimney caps last 3 to 25+ years, depending mostly on the material. Stainless steel and copper ones tend to last longer than galvanized.
As a general rule, the top of the chimney cap must be at least 5 inches above the top of the flue.
