When replacing beats repairing
No single test decides it, but the published guidance points to a few signs:
- Age. HomeAdvisor gives aluminum or galvanized about 20 years. This Old House gives seamless 20 to 30 years and sectional 10 to 15.
- Rust. Bob Vila says galvanized steel rusts after about 20 to 25 years.
- Repeated repairs. Bob Vila notes frequent repairs can come to more than replacement. At HomeAdvisor's average of $395 a repair, the total adds up quickly.
- A damaged seamless run. If a small section can't be patched, HomeAdvisor says the whole run usually gets replaced.
- Box gutters with damaged soffit or cornice. HomeAdvisor says these may favor replacement.
- Vinyl that has gone brittle. Bob Vila says vinyl turns brittle in colder climates and lasts about 10 years. Huntsville's normal first freeze is November 8 and its normal last freeze is March 24, so ask how vinyl holds up here.
What doesn't count as a sign: paint. HomeAdvisor says painting doesn't solve structural or performance issues, so faded gutters aren't a reason on their own, and fresh paint doesn't buy tired gutters more time.
What the job involves
The old system comes down, the wood behind it gets looked at, and the new runs go up with new downspouts or reused ones. Ask whether your price includes hauling the old material away. Bob Vila lists old gutter removal at $0.65 to $0.85 per foot, which on a 200-foot house comes to $130 to $170.
Once the old gutter is off, three things are worth a look before the new one goes up:
Fascia
The new gutter is only as firmly attached as the wood behind it. Ask how any rot that turns up will be priced before work starts, so it isn't a surprise. HomeAdvisor lists $6 to $20 per foot for fascia and soffit work, and $500 to $4,000 for dry rot. Its page isn't consistent with itself, so use those as rough markers.
Drip edge
Ask how the roof edge meets the back of the new gutter. One gutter guard maker's blog describes a drip edge overlapping the gutter back with about a 1/4-inch gap, and an old trade forum thread warns that leaving drip edge off puts the roof deck at risk. Neither is a code citation. They're a reason to ask the question.
Kick-out flashing
The Department of Energy's building science program describes kick-out flashing as a way to keep water from spilling past the gutter onto the wall, in hot-humid and mixed-humid heavy-rain climates. If a roof edge dies into a wall on your house, ask whether it has this flashing.
The chance to resize
If the old gutters overflowed in hard rain while clean, don't simply replace them like for like. A 2015 Fine Homebuilding article lists undersizing by default to 5-inch and too few downspouts among common mistakes.
Worked numbers: the same eave, two ways
Assume a 40-foot rear eave, 15 feet from eave to ridge, 6-in-12 pitch, so a design area of 660 square feet. Rain rates are NOAA's 8.20 and 12.8 inches per hour for downtown Huntsville. Capacities are per outlet, gutter level.
| Setup | At 8.20 in/hr | At 12.8 in/hr |
|---|---|---|
| 5-inch, one downspout | 673 sq ft | 431 sq ft |
| 5-inch, two downspouts | 1,346 sq ft | 863 sq ft |
| 6-inch, one downspout | 971 sq ft | 622 sq ft |
| 6-inch, two downspouts | 1,941 sq ft | 1,244 sq ft |
Against 660 square feet, one 5-inch run with one outlet barely clears the 10-year rate. A second outlet clears both rates. This is teaching math, not a design. Valleys, upper roofs and elbows aren't counted. See the full method.
Choosing material the second time around
| Material | Published lifespan | Published per-foot price |
|---|---|---|
| Aluminum | About 20 years (HomeAdvisor) | $4 to $14 (Bob Vila); $4 to $9 seamless, material only (Angi); $7 (This Old House) |
| Galvanized | Rusts after about 20 to 25 years | $6 to $14 (Bob Vila); $8 to $10 seamless, material only (Angi); $9 (This Old House) |
| Copper | About 50 years (HomeAdvisor) | $25 to $40+ (Bob Vila); $15 to $25, material only (Angi); $20 (This Old House) |
| Vinyl | About 10 years (Bob Vila) | $3 to $6 (Bob Vila); $3 to $5 seamless, material only (Angi); $4 (This Old House) |
On an older house, half-round may be what's there now. This Old House says half-round generally carries less volume at the same width, and Angi says it's more commonly used on historic homes. If your house is in a Huntsville historic district, read the historic district page first. Gutters are named on the city's staff review list there.
What goes wrong on replacements
- Same size, same problem. New gutters that match the old ones will overflow where the old ones did if the size or outlet count was the cause.
- Rot found late. Without an agreed way to price it, wet fascia becomes an argument halfway through the job, and HomeAdvisor lists dry rot repair at up to $4,000.
- Downspouts ignored. Standard downspouts discharge 1 to 3 feet out, per Bob Vila, while the Department of Energy program says at least 5 feet from the foundation. A replacement is a good time to fix that. See downspouts and drainage.
- A slope that opens a gap. An editor at Green Building Advisor notes a sloped gutter can open a gap under the drip edge.
What replacement costs
These are national figures, not Huntsville prices, and the written price for your house is what counts.
- This Old House (updated 10/09/2026): $600 to $5,800, average $3,200, on a typical 2,000-square-foot home (about 200 feet of gutter).
- Bob Vila (June 9, 2023, HomeAdvisor data): $622 to $1,677, average $1,135; about $1,200 for one story, about $2,000 for two.
- HomeAdvisor says a full replacement falls "between $1,600 and $2,175 per job", which doesn't line up with the averages above.
Worked numbers: 200 feet of seamless aluminum
Assume 200 feet and Angi's installed figure for seamless gutters of $4 to $10 per foot: $800 to $2,000. Add Bob Vila's removal figure: $130 to $170. That gives about $930 to $2,170, before any fascia work. This is arithmetic on national figures, not a local price.
When replacement isn't the right call
- One bad joint on otherwise sound gutters. Try a repair first.
- Clogging is the only complaint. Cleaning or guards may be the answer.
- Storm damage with a claim open. Talk to your agent before you sign. See hail and wind damage.
Permits
No local agency page read for this site says whether replacing gutters needs a permit. Unincorporated Madison County lists "Roofing or re-roofing - regardless of cost" and gutters aren't named, so if your roof is being replaced at the same time, ask how the two are treated: 256-746-2950. In Huntsville, call the Inspection Department at 256-427-5331. In Madison, call the Building Department at 256-772-5644.
The hiring guide covers what to ask whoever takes on the replacement.
Questions homeowners ask
How long should gutters last before replacing them?
Published figures run from about 10 years for vinyl to about 50 for copper. Aluminum or galvanized is about 20. Condition matters more than the calendar.
Should gutters come off when the roof is replaced?
No source read for this site says they must. Ask your roofer how the drip edge and the gutter back will fit together, since that joint is where the two jobs meet.
Can I drop a downspout if I go to a bigger gutter?
Be careful. In the sizing method, a second outlet adds more than going up one gutter size. Using the numbers above, a 5-inch gutter with two outlets serves 1,346 square feet at 8.20 inches per hour, and a 6-inch with one outlet serves only 971. See downspouts and drainage.
Should the fascia be replaced at the same time?
Only if it needs it, but this is the easiest time to find out. Ask to see any soft areas once the old gutter is off.
Is it worth upgrading to thicker aluminum?
That's your call. Stores tend to stock 0.019 to 0.025 inch, and contractors 0.027 or 0.032, per Angi. Ask which one your price is based on.
How this site helps: it hands your request to one independent local contractor, and the replacement itself is between you and them.
