Quick answer: Chimney chase cover replacement typically costs $300 to $700, with labor included. A custom stainless steel chimney chase cover usually runs $500 to $1,200 installed. Copper starts near $1,500. Multi-flue chases, steep roofs, and rotted framing raise the price.
A rusty chimney chase cover lets rain into the frame around your chimney. That water damage costs far more than a new cover. This guide breaks down chimney chase cover replacement cost for Georgia homeowners in 2026.

What Is a Chimney Chase Cover?
A chimney chase cover is a flat metal pan that seals the top of a chimney chase. Some pros call it a top pan or chase pan. The chase is the framed box around a factory-built chimney. It is usually wood with siding. The cover keeps rain, snow, leaves, and animals out.
Homeowners often confuse three parts:
- Chimney chase cover: covers the entire top of the chase on a prefabricated chimney.
- Chimney cap: sits on the flue pipe and keeps rain and animals out of the flue only.
- Chimney crown: a concrete slab on top of a masonry chimney. Cracked crowns may need chimney crown waterproofing.
A framed chimney needs both a chimney cap and a chase cover. One protects the flue. The other protects the structure.
Chimney Chase Cover Replacement Cost by Material
The cost to replace a chimney chase cover depends mostly on material and chase size. The table shows typical installed ranges from 2026 industry figures. Use it as a planning range, not a quote.
Material | Typical installed price | Typical lifespan | Best for |
Galvanized steel | $300 to $600 | 5 to 10 years | Short-term budget fix only |
Stainless steel | $500 to $1,200 | 25+ years with proper install | Most Georgia homes |
Copper | $1,500 to $2,500+ | Decades | Historic or high-end exteriors |
Multi-flue or oversized custom pan | Higher than the ranges above | Depends on material | Wide chases with two or more flues |
Industry guides put the average replacement at about $300 to $700, with labor. Premium metals, steep roofs, and complex chases push totals higher. Our chimney cost guides list other common repair prices.
A framed chimney needs both a chimney cap and a chase cover. One protects the flue. The other protects the structure.
Galvanized Steel: Lowest Price, Shortest Life
Galvanized steel costs about $300 to $600 installed. It often rusts within 5 to 10 years. Rust streaks can also stain your siding. Treat it as a short-term fix.
Stainless Steel: Best Value for Most Homes
A stainless steel chimney chase cover typically costs $500 to $1,200 installed. It resists rust and handles Georgia rain well. Many last 25 years or more when installed correctly.
For most homeowners, this is the smart middle ground.
Copper: Premium Look and Longest Life
Copper covers cost about $1,500 to $2,500 or more installed. Copper is very durable and develops a natural patina. It suits historic homes and high-end exteriors.
Aluminum: Light but Easy to Dent
Aluminum is light and resists rust. It dents easily in storms, though. Stainless steel holds up better to falling limbs.
What Affects the Cost to Replace a Chimney Chase Cover?
Two homes on the same street can get different quotes. These factors explain why.
Material and Thickness
Stainless covers come in 24, 22, or 20 gauge steel. A lower gauge number means thicker metal. Thicker metal costs more but resists dents and warping.
Chase Size and Number of Flues
A small single-flue chase needs a simple pan. A wide chase with two or three flues needs more metal and more cutouts. It also needs a fully custom fit.
Roof Pitch and Chimney Height
Steep roofs and tall chimneys take more time and safety gear. Labor rises with harder access.
Condition of the Chase Below
Soaked framing must be repaired before the new cover goes on. Siding repair and flashing work add cost. Skipping them wastes the new cover.
Design Details
A cross-break is a slightly raised center that sheds water. Welded seams and a deeper side skirt also add cost. These features keep leaks away.
Why a Failing Chimney Chase Cover Costs More Than a New One
Water is the enemy of every chimney. The chase cover is the only barrier between rain and the wood frame below.
Water pools on the metal and finds a seam or screw hole. Then it runs down the flue pipe. From there it can:
- Rot the wood framing and siding around the chase
- Rust the metal firebox and chimney sections
- Stain ceilings and walls near the fireplace
- Feed mold and mildew inside the home
- Let pests into the chase, which may call for animal removal guards
Georgia’s humid weather and heavy rain make this worse. Metal stays wet longer, so weak covers rust faster.
Signs You Need a New Chase Cover
- Rust streaks running down the chase siding
- Orange or brown stains near the top of the chimney
- Water stains on the ceiling or inside the firebox
- Dented, warped, or sagging metal on top
- Water that pools on the cover after rain
- A loose cover that rattles in the wind
- Cracked or missing sealant around the edges
Two or more signs mean it is time for a Level 1 chimney inspection. Use a Level 2 inspection if water may have reached the flue. Early replacement costs much less than rebuilding a rotted chase.
Why Chase Covers Fail
- Cheap metal. Galvanized steel often rusts through in 5 to 10 years.
- A sagging center. Water pools instead of running off.
- Screws through the top. Fasteners in the top surface can leak.
- Poor fit. A cover without an overhang lets water run behind the siding.
- No checkups. Cracked sealant goes unnoticed because few people climb up to look.
Stainless Steel Chimney Chase Cover: Is It Worth the Cost?
The cheapest cover today is rarely the cheapest over 25 years. A galvanized cover replaced every 5 to 10 years could cost $750 to $3,000 in total. That figure excludes any water damage.
A single stainless steel cover costs about $500 to $1,200. It can last that whole stretch.
Not every stainless cover is equal. A good chimney chase cover in stainless steel should include:
- Custom fit: measured to your chase, not an off-the-shelf box.
- Cross-break design: a raised center so water runs off instead of pooling.
- Welded seams: no gaps where water can slip through.
- Side skirt overhang: about 3 inches, so water drips clear of the siding.
- Stainless fasteners: regular screws rust and leave streaks on the chase.
- High-temperature sealant: a silicone bead seals the top edge of the chase.
Want a different look? Ask about powder coating. Regular paint tends to peel off stainless steel.
How Chimney Chase Cover Replacement Works
A professional replacement follows a clear process:
- Inspect and measure. The technician checks the old cover, chase, flashing, and siding. Then they measure the chase top and flue openings.
- Fabricate the new cover. A custom pan is formed to fit your chimney exactly.
- Remove the cap and old cover. The cap comes off first. Then the screws or nails come out and the old cover lifts away.
- Check the chase top. The crew looks for soft wood or water damage and handles needed chimney repairs first.
- Seal and set the new cover. A bead of high-temperature sealant goes down. The new cover sits flush on the chase.
- Fasten and finish. Stainless screws go through the side skirt, not the top surface. The cap goes back on.
- Test the drainage. The technician confirms water runs off instead of pooling.
You can try it yourself, but errors cause leaks. A wrong measurement or misplaced screw is enough. Roof work also carries a real fall risk.
Repair, Seal, or Replace?
Chimney waterproofing or sealant can slow a small leak for a short time. It cannot fix thin, rusted metal.
Replace the cover if:
- Rust has eaten through the metal
- The cover sags or water pools on it after rain
- Seams or corners have opened up
- The cover is dented or warped
- Rust stains keep coming back on the siding
Questions to Ask Before You Hire
Compare quotes on equal terms. Ask each company:
- Which material and stainless steel grade will you use?
- What gauge is the metal?
- Are the seams welded?
- How deep is the side skirt?
- Are stainless screws and high-temperature sealant included?
- Will you check the flashing, cap, and chase framing?
- What does the warranty cover, and is it in writing?
- Is the price an itemized, written quote?
