If you’re considering a metal roof for your St. Louis home or business, cost is probably your first question. The short answer: metal roofing in St. Louis typically costs $8 to $13 per square foot installed for residential projects, which works out to roughly $12,000 to $26,000 for an average 1,500 to 2,000 square foot roof.
But that range is wide for a reason. Your final cost depends on the panel profile, roof complexity, whether tear-off is needed, and other factors we’ll break down below. As a St. Louis metal roofing contractor who installs Central States metal panels every week, here’s an honest look at what you’ll actually pay in 2026.
Metal Roof Cost by Panel Type
Not all metal roofing costs the same. The panel profile you choose is the biggest factor in your installed price. Here’s what each option runs in the St. Louis market as of 2026:
Our most popular residential option is Horizon-Loc from Central States Manufacturing. It gives you the clean, modern look of a standing seam roof at a significantly lower price point because it doesn’t require hand-seaming during installation. It’s 26-gauge Galvalume steel with a Class 4 UL 2218 impact rating and a limited lifetime warranty plus 40-year paint warranty. Expect to pay $9 to $12 per square foot installed.
For homeowners on a tighter budget, or for garages, shops, and agricultural buildings, Panel-Loc Plus is our exposed fastener option. Available in 26 or 29 gauge with 36-inch coverage panels, it installs faster and costs less per square foot while still delivering decades of performance. Installed cost typically runs $6 to $9 per square foot.
Factors That Affect Your Metal Roof Price
The per-square-foot ranges above are averages. Here’s what moves your actual project cost up or down:
Roof Size and Pitch
Larger roofs cost more total but typically less per square foot because fixed costs (setup, mobilization, flashing) are spread over more area. Steeper pitches (8/12 and above) increase labor time and require additional safety equipment, adding 10–20% to labor costs.
Tear-Off vs. Overlay
If your existing roof needs to come off first, expect to add $1 to $2 per square foot for tear-off and disposal. In some cases, metal panels can be installed over a single layer of existing shingles, saving that cost entirely. We inspect every roof and advise honestly on whether overlay is appropriate.
Roof Complexity
Hips, valleys, dormers, skylights, chimneys, and multiple penetrations all require custom flashing work. A simple gable roof with minimal penetrations will be at the low end of the price range. A complex hip roof with dormers and skylights will be at the high end.
Decking Condition
If your roof decking has rot, soft spots, or needs reinforcement, that repair is added to the project cost. We don’t know the decking condition until the old roof comes off, which is why we provide an initial estimate range and adjust once tear-off reveals the full picture.
Panel Profile and Color
Higher-gauge steel (24 gauge vs. 26 gauge) and premium color finishes cost more. Textured matte finishes on Horizon-Loc add a modest premium over standard smooth finishes. Custom colors ordered outside the standard palette also add lead time and cost.
Metal Roof vs. Asphalt Shingles: The Real Cost Comparison
The most common comparison we get is metal vs. asphalt. Asphalt shingles cost less upfront — typically $4 to $7 per square foot installed in St. Louis. But the lifetime cost tells a different story.
A 30-year architectural shingle roof realistically lasts 15 to 25 years in the St. Louis climate, where hail, wind, and temperature swings are constant. That means over a 50-year period, you’ll likely pay for two or three asphalt roof replacements. One metal roof covers that entire span — and then some.
When you add energy savings and potential insurance discounts on top of the longevity advantage, metal roofing is often the lower-cost option over the life of the home. The breakeven point versus asphalt typically hits between year 8 and year 15.
Can You Finance a Metal Roof in St. Louis?
Yes. Most homeowners finance metal roofing projects through home improvement loans, home equity lines of credit (HELOCs), or financing programs offered through roofing contractors. At Meridian, we can walk you through your options during the estimate process so you understand the monthly payment before making a decision.
Insurance Discounts for Metal Roofing
This is one of the most overlooked financial benefits of metal roofing. Many homeowners insurance carriers in Missouri offer premium discounts for roofs with a Class 4 UL 2218 impact resistance rating — which both Horizon-Loc and Panel-Loc Plus carry. The discount typically ranges from 5% to 35% off your annual premium, depending on the carrier.
Over the 40+ year lifespan of a metal roof, those annual savings add up significantly. We recommend calling your insurance agent before making a final decision to confirm what discount you qualify for.

Metal Roof Cost FAQs
How much does a metal roof cost per square foot in St. Louis?
Metal roofing in St. Louis costs $6 to $12 per square foot installed, depending on the panel type. Horizon-Loc (concealed fastener, standing seam look) runs $9 to $12 per square foot. Panel-Loc Plus (exposed fastener) runs $6 to $9 per square foot.
Is a metal roof worth the extra cost?
For most St. Louis homeowners who plan to stay in their home for 10+ years, yes. A metal roof lasts 40 to 70 years versus 15 to 25 for asphalt, eliminates multiple replacements, reduces energy costs by up to 25%, and often qualifies for insurance discounts. The breakeven point versus asphalt is typically between year 8 and year 15.
How long does a metal roof last compared to shingles?
Metal roofs last 40 to 70 years. Standard architectural asphalt shingles last 15 to 25 years in the St. Louis climate. That means a homeowner who installs asphalt will likely need 2 to 3 roofs over the same period a single metal roof would cover.
Does insurance cover a metal roof?
If your existing roof was damaged by a covered event (hail, wind, fallen tree), most insurance policies will cover replacement with a metal roof. Additionally, many carriers offer ongoing premium discounts of 5–35% for Class 4 impact-rated metal roofing systems like Horizon-Loc and Panel-Loc Plus.
Can I install a metal roof over shingles?
In many cases, yes. If the decking is solid and there’s only one existing layer of shingles, metal can be installed over it. This saves on tear-off and disposal costs ($1–$2 per square foot). We inspect every roof to determine what’s structurally appropriate.
