Metal Roof Cost Calculator

Enter your roof size and pitch for a 2026 metal roofing estimate with the material and labor split shown separately.

A metal roof costs roughly $12 to $18 per square foot installed in 2026, or about $20,000 to $31,000 on a 1,700 sq ft home. Exposed-fastener panels sit at the low end and standing seam at the high end.

What drives metal roofing cost

The system matters more than the metal. Exposed-fastener corrugated panels are the cheapest way to get a metal roof and run $4 to $9 per square foot installed, but the gaskets under those exposed screws are a maintenance item every 10 to 20 years. Standing seam hides its fasteners under the seam and runs $12 to $18, with nothing to re-torque later.

Gauge and coating change the number too. 26-gauge steel is standard residential; 24-gauge is stiffer and costs more. A Kynar 500 (PVDF) finish holds colour far longer than a polyester coating and is worth the premium on any roof you intend to keep.

Metal versus asphalt over time

Metal costs about two to three times asphalt up front and lasts about three times as long, 40 to 70 years against 15 to 25. On cost per year of service the two are close, and metal wins outright if you stay in the house long enough to avoid a second asphalt replacement.

The secondary benefits are real but harder to price: metal reflects solar gain and can cut cooling load in hot climates, it is non-combustible in wildfire zones, and many insurers discount for it. It is also considerably louder in rain unless installed over solid decking with underlayment, which is standard practice on homes.

Frequently asked questions

How much does a metal roof cost in 2026?

About $12 to $18 per square foot installed for standing seam, or roughly $20,000 to $31,000 on a 1,700 sq ft home. Exposed-fastener panel systems run $4 to $9 per square foot.

Is a metal roof worth the extra cost?

If you plan to stay more than about 15 years, usually yes. Metal lasts 40 to 70 years against 15 to 25 for asphalt, so you avoid a full second replacement, and many insurers discount for it.

Can metal roofing go over existing shingles?

Often yes, and it is a real saving on tear-off and disposal. The deck has to be sound and code has to permit the added layer. Most installers add a slip sheet or furring to prevent abrasion and trapped moisture.

How long does a metal roof last?

40 to 70 years for steel and aluminium systems, and longer for copper or zinc. The finish usually fails before the metal does, which is why the coating specification matters.

Are metal roofs noisy in rain?

Not on a house. Residential metal goes over solid decking with underlayment, which damps sound to roughly the level of an asphalt roof. The noise reputation comes from barns, where panels sit on open purlins.
