The band, the lifespan, the weight

Installed cost band	$600–$950 per square — typical published band; quotes vary by region, access, and tear-off
Lifespan band	25–45 years (≈$22/sq per year of service at midpoints)
Weight class	Light (no structural review needed)
Pitch suitability	Slopes of 3/12 and up; exposed fasteners make very low slopes a leak risk.

Verdict

The value path into metal. Best on simple, lower-visibility roofs; on a complex main residence, price standing seam before you commit to exposed fasteners.

Where it earns the stamp

✓ Metal longevity at a price band that overlaps premium shingles
✓ Fast installation over large simple roofs — great for garages, shops, ranches
✓ Light weight suits older framing

Watch for

✗ Hundreds of exposed gasketed screws that need inspection/re-tightening over time
✗ Oil-canning and a utilitarian look on prominent house roofs
✗ Lifespan trails standing seam — the gaskets age before the steel does

FAQ

How much does corrugated / exposed-fastener metal cost installed?

A typical published band is $600–$950 per square (100 sq ft) installed — materials and labor, before tear-off. On a 2,000 sq ft footprint at 6/12 pitch (about 22.4 squares, moderate complexity) that benchmarks to roughly $17,696–$28,952 including tear-off. Bands benchmark quotes; region, access, and scope move real bids.

How long does corrugated / exposed-fastener metal last?

A typical service-life band is 25–45 years. At the midpoint of the cost and lifespan bands, that works out to roughly $22 per square per year of service — the number to use when comparing materials honestly.

What roof pitch does corrugated / exposed-fastener metal need?

Slopes of 3/12 and up; exposed fasteners make very low slopes a leak risk.
