How Much Does an Aluminum Roof Cost Per Square Foot?
Installed, a premium aluminum roof typically costs about $12 to $20+ per square foot — roughly $1,200 to $2,000+ per roofing square (100 sq ft). Most homeowners land in the middle of that band, with simpler roofs and lighter profiles at the low end and complex, steep, or specialty-profile roofs at the high end. Where your project falls depends on the aluminum profile you choose, how complicated your roof is, whether an old roof has to come off, your region, and local labor rates. Every figure on this page is a planning estimate, not a quote — the only way to get your exact number is a measured, on-site assessment.
Below we break down the per-square-foot and per-square ranges, explain why aluminum sits above steel on price, and walk through the drivers that move your number. When you're ready for a real figure for your home, request a free quote.
Quick Answer
Installed, aluminum roofing typically costs about $12 to $20+ per square foot, or roughly $1,200 to $2,000+ per roofing square (100 sq ft). Lighter metal shingle, slate, shake, and tile profiles on simple roofs sit at the low end, while standing seam and complex or specialty roofs reach the high end. These are planning estimates — a measured on-site quote gives your exact number.
Aluminum roof cost per square foot & per square (installed)
Roofers price in "squares" — one square equals 100 square feet of roof area. The table below shows typical installed ranges (materials + labor) by profile and roof complexity. These are illustrative 2026 planning estimates for a standard residential re-roof; your quote may fall outside these ranges.
| Aluminum profile / scenario | Cost per sq ft (installed) | Cost per square (100 sq ft) | Typical fit |
|---|---|---|---|
| Aluminum shingle / slate / shake / tile — simple roof | $12 – $15 | $1,200 – $1,500 | Low-to-moderate pitch, few penetrations, easy access |
| Aluminum shingle / slate / shake / tile — complex roof | $14 – $18 | $1,400 – $1,800 | Steep pitch, multiple valleys, dormers, skylights, cut-up rooflines |
| Aluminum standing seam — simple roof | $14 – $17 | $1,400 – $1,700 | Clean gable/hip lines, long uninterrupted runs |
| Aluminum standing seam — complex roof | $16 – $20+ | $1,600 – $2,000+ | Steep, multi-facet roofs; custom flashing and detailing |
| Specialty / premium upgrades (custom color/finish, bespoke details) | $20+ | $2,000+ | Architectural showcase homes and bespoke details |

As a quick sanity check: a 2,000 sq ft roof at $15 per square foot is roughly $30,000 installed; the same roof at $18 per square foot is about $36,000. Smaller roofs often carry a higher per-square-foot cost because fixed mobilization and setup costs get spread over less area.
Why aluminum costs more per square foot than steel
Aluminum is usually the priciest of the common metal roofing options — typically running above steel per square foot. That premium buys real, measurable advantages that matter most over a roof's decades-long life:
- It won't rust. Aircraft-grade aluminum contains no iron and forms a self-protecting oxide layer, so it doesn't rust the way steel can once its coating is scratched or ages. That's a core reason it's specified for demanding environments.
- It's coastal- and climate-friendly. Salt air is brutal on steel. Aluminum's corrosion resistance makes it the go-to metal for coastal, high-humidity, and harsh-weather homes where longevity is non-negotiable.
- It's lighter than steel. Aluminum weighs less, which reduces structural load and can make installation over existing structures easier — a genuine advantage on many homes.
- It's nearly 100% recyclable. Aluminum roofing typically contains significant recycled content and is recyclable at end of life, which appeals to sustainability-minded buyers.
- Its finish is built to last. Interlock's Alunar finish uses 70% PVDF resin for long-term color and finish protection against fade and chalk.
In other words, you pay more up front for a metal that resists the exact failure modes — rust and corrosion — that shorten a roof's life. For a longer-tenure or coastal home, that trade-off is often what makes aluminum the right call. We compare the two head-to-head in aluminum vs. steel roofing.
What drives your aluminum roof cost up or down
Two homes with identical square footage can get very different quotes. Here's what moves the number:
- Profile / product line. Standing seam and specialty finishes generally cost more per square foot than metal shingle, slate, shake, or tile profiles, because of the material forming, panel engineering, and detailing involved.
- Roof complexity. Steep pitch, multiple valleys, hips, dormers, chimneys, skylights, and cut-up rooflines all add labor, flashing, and waste. A simple gable roof is far cheaper per square foot than an intricate one of the same size.
- Tear-off & deck condition. Removing and disposing of an old roof adds cost, and any rotted or damaged decking discovered underneath must be repaired before installation — a common source of price movement.
- Region. Material freight, local demand, permitting, and code requirements (wind, snow, fire) vary by market and shift the price. Confirm coverage in your service area.
- Labor & installer. Metal roofing is a specialized trade; skilled installation isn't cheap, and local labor rates and installer experience are a major part of the total. See our certified installers.

Is the premium worth it?
Aluminum's higher per-square-foot cost is best judged over the life of the roof, not on day one. A quality aluminum roofing system is designed to be a once-in-a-lifetime, "never re-roof again" investment with a 50-75 year lifespan — while asphalt is typically replaced multiple times over the same period. When you spread the cost across decades of service and factor in corrosion resistance, low maintenance, and potential resale and insurance benefits, the premium often pencils out.
Interlock backs its aluminum systems with a transferable Lifetime Warranty, which adds resale confidence and protects your investment if you sell. For the bigger picture on metal-roof value, read is a metal roof worth it? and how much does a metal roof cost?
Why small roofs cost more per square foot
It surprises many homeowners, but a small roof can carry a higher per-square-foot cost than a large one. Fixed costs — mobilization, setup, permitting, delivery, and minimum crew time — don't shrink much with roof size. On a small roof those fixed costs get spread over fewer square feet, pushing the per-square-foot rate up. On a large roof they're distributed across more area, which can lower the per-square-foot rate even when the total project costs more.
This is exactly why a single "cost per square foot" number can't stand in for a real quote. Pitch, access, complexity, and total size all interact. A measured, itemized estimate is the only way to know where your roof actually lands.

Aluminum roof cost FAQs
Common questions homeowners ask about aluminum roof pricing, per-square-foot ranges, and what moves the number.
How much does an aluminum roof cost per square foot?
Installed, aluminum roofing typically costs about $12 to $20+ per square foot, or roughly $1,200 to $2,000+ per roofing square (100 sq ft). Lighter shingle, slate, shake, and tile profiles on simple roofs sit at the low end; standing seam and complex or specialty roofs sit at the high end. These are planning estimates — request a free on-site quote for your exact number.
Why does aluminum roofing cost more than steel?
Aluminum generally costs more per square foot than steel because aircraft-grade aluminum won't rust, resists salt-air corrosion (ideal for coastal and harsh climates), weighs less, and is nearly 100% recyclable. You pay a premium for a metal that resists the exact rust-and-corrosion failure modes that can shorten a steel roof's life, which is why it's often chosen for long-tenure and coastal homes.
What drives the cost of an aluminum roof up or down?
The biggest drivers are the profile you choose (standing seam and specialty finishes cost more than shingle, slate, shake, or tile), roof complexity (pitch, valleys, dormers, skylights), whether an old roof needs tear-off and disposal, the condition of the decking underneath, your region, and local labor rates. Two same-size roofs can price very differently based on these factors.
How much does an aluminum roof cost per square?
A roofing 'square' is 100 square feet. Installed aluminum roofs typically run about $1,200 to $2,000+ per square. To estimate a full roof, multiply your roof's total squares by that range — for example, a 20-square (2,000 sq ft) roof at $1,500 per square is about $30,000 installed. These are estimates only; a free quote gives your exact figure.
Is a premium aluminum roof worth the extra cost?
For many homeowners, yes. Aluminum's higher up-front cost is best judged over the life of the roof: it's engineered to be a once-in-a-lifetime, 'never re-roof again' investment with a 50-75 year lifespan and a transferable Lifetime Warranty, while asphalt is typically replaced multiple times over the same span. Factor in corrosion resistance, low maintenance, and potential resale and insurance benefits, and the premium often pays for itself over time.
Why is my small roof more expensive per square foot?
Smaller roofs often carry a higher per-square-foot cost because fixed costs — mobilization, setup, permitting, and crew time — get spread over less area. A larger roof distributes those fixed costs across more square feet, which can lower the per-square-foot rate even when the total project costs more.
Does aluminum roofing rust?
No. Aircraft-grade aluminum contains no iron and forms a self-protecting oxide layer, so it does not rust the way steel can when its coating is scratched or ages. This corrosion resistance is a key reason aluminum is favored for coastal and high-humidity homes and is a major factor in its longer service life.
What finish protects an aluminum roof's color?
Interlock aluminum roofs use the Alunar finish, built on 70% PVDF resin, which provides long-term protection against fade and chalk so the color stays vibrant for decades. You can review the details on our coating specifications page.
