Stone-coated steel roofing costs about $7 to $13 per square foot installed, or $700 to $1,300 per roofing square, according to HomeGuide's 2026 cost guide; Boral, Metro and Gerard systems run $7.50 to $14.50, and installation labour alone is $3.50 to $7.00 per square foot. A 2,000 sq ft roof comes to roughly $14,000 to $26,000 before removing the old roof, against $9,000 to $13,000 for architectural shingles. Stone-coated steel is steel pressed into a shake, tile or shingle profile and finished with bonded stone chips; it weighs under two pounds per square foot (Fixr), many products carry a Class 4 impact rating, and it is commonly expected to last 40 to 60 years. The calculator prices your roof, adds tear-off, and compares the cost per year with asphalt.

About $7–$13 per sq ft installed, or $700–$1,300 per square, according to HomeGuide (2026). Boral, Metro and Gerard systems run $7.50–$14.50. A 2,000 sq ft roof is roughly $14,000–$26,000 before tear-off.
HomeGuide puts installation at $3.50–$7.00 per sq ft, so labour is roughly half of the installed price. Complex roofs with many hips and valleys sit at the top of the range.
It is lighter than tile (under 2 lb per sq ft according to Fixr), resists hail and wind well, and is commonly expected to last 40–60 years against 25–30 for architectural shingles. It costs roughly double to install.
Many systems are designed to be installed on battens over one existing layer of shingles where code allows, which saves the tear-off. The manufacturer's instructions and your local building department decide.
In hail regions some insurers discount Class 4 impact-rated roofs, and many stone-coated products carry that rating. Ask your carrier for the exact credit before you choose.
