Should You Replace Gutters When Replacing Your Roof?
Short answer: usually yes. Here's when it makes sense, when you can keep your existing gutters, and how much you save by bundling the work.
When you're already spending $10,000–$25,000 on a new roof, the question of whether to replace your gutters too is a smart one. The answer depends on their age, condition, and material — but more often than not, bundling gutters with a roof replacement is the best move financially.
When You Should Replace Gutters With Your Roof
Replace your gutters during the roof replacement if any of these apply:
- Gutters are 15+ years old — aluminum gutters last 20–30 years, so if they're past the halfway point, you'll need new ones within a few years anyway
- Visible sagging or pulling away — the hangers or fascia board behind them are failing
- Leaking at seams — sectional gutters develop leaks at joints over time
- Rust or corrosion — especially common on older steel gutters
- Frequent clogs despite cleaning — the pitch or size may be wrong for your roofline
- Water damage at the foundation — gutters aren't directing water away properly
Homes in Bloomfield, Nutley, and Belleville with mature oak and maple trees tend to see gutter deterioration faster due to the constant leaf load and debris accumulation.
When You Can Keep Your Existing Gutters
Your gutters may be fine to keep if:
- They're less than 10 years old and in good shape
- Seamless aluminum in good condition — no leaks, proper pitch, secure mounting
- Copper gutters — these last 50+ years and develop an attractive patina; don't replace these unless they're actually failing
- Recently repaired or resealed — if you invested in gutter maintenance within the last few years
Even if you keep existing gutters, a good roofing crew will temporarily remove them during the roof replacement to install proper drip edge flashing, then reinstall them afterward. This ensures the gutter-to-roof connection is watertight. Ask your contractor about this — not every crew does it.
Cost Savings of Bundling Gutters With Roof Replacement
Replacing gutters during a roof replacement is significantly cheaper than doing it as a separate project:
| Scenario | Cost (150–200 LF) | Why |
|---|---|---|
| Gutters bundled with roof | $600–$1,800 | Crew and equipment already on site |
| Gutters as separate project | $1,000–$2,500 | Separate mobilization, setup, and cleanup |
The savings come from labor efficiency. The scaffolding or ladders are already set up, the old gutters have already been removed for the roof work, and the crew can install new gutters immediately after completing the roof edge. No separate truck roll, no separate cleanup. For full pricing details, see our gutter replacement cost guide.
Gutter Material Options
If you decide to replace, here are your options ranked for NJ homes:
- Seamless aluminum (best value): $4–$9/LF installed. Rust-proof, handles freeze-thaw well, 20–30 year lifespan. This is what we install on most homes across West Orange, Montclair, and Livingston.
- Copper (premium): $15–$30/LF installed. Beautiful, lasts 50+ years, develops a green patina. Common on historic homes in Glen Ridge and Millburn.
- Vinyl (not recommended for NJ): $3–$5/LF installed. Cheapest upfront but cracks in NJ cold, only lasts 10–15 years, and looks cheap. Not worth the savings.
NJ Gutter Considerations
Essex County has specific conditions that affect gutter performance and longevity:
- Heavy leaf load: Towns like South Orange, Maplewood, Roseland, and Essex Fells have dense tree coverage. Oversized 6-inch gutters handle debris better than standard 5-inch. Consider gutter guards to reduce cleaning frequency.
- Ice dam prevention: Proper gutter sizing and placement work with ice dam prevention strategies. Heat cables can be installed in new gutters to prevent ice buildup during NJ winters.
- Foundation protection: NJ's heavy rainfall means gutters are critical for directing water away from your foundation. Make sure downspouts discharge at least 4–6 feet from the foundation wall.

Frequently Asked Questions
How much do new gutters cost when added to a roof replacement?
When bundled with a roof replacement, new aluminum gutters typically cost $4–$9 per linear foot installed. A typical Essex County home needs 150–200 linear feet, putting the total at $600–$1,800 — 15–25% less than a standalone gutter project.
Can roofers damage gutters during roof replacement?
Yes, it's common for existing gutters to sustain minor damage during roof replacement from falling debris, ladders, and foot traffic near the roof edge. A reputable roofer will take precautions and repair any damage.
What type of gutters are best for NJ homes?
Seamless aluminum gutters are the best choice for most NJ homes. They resist rust, handle freeze-thaw well, come in many colors, and last 20–30 years. Avoid vinyl gutters in NJ — they crack in the cold.
Should I add gutter guards when replacing gutters?
Gutter guards are worth considering for Essex County homes surrounded by trees. Adding them during roof and gutter replacement is the most cost-effective time. See our gutter guard cost guide for pricing details.
How long do gutters last?
Aluminum gutters last 20–30 years, copper 50+ years, steel 15–25 years, and vinyl 10–15 years. NJ weather and heavy leaf loads can shorten these lifespans.
Do I need to replace downspouts too?
If you're replacing gutters, replacing the downspouts at the same time is recommended. Old downspouts may not connect properly to new gutters, and the additional cost is minimal when the crew is already on site.
