On a 2,000 square foot roof, an architectural shingle job runs roughly 9,000 to 16,000 dollars and standing seam steel 20,000 to 36,000. The gap is commonly 10,000 to 20,000 dollars. An exposed fastener metal panel narrows it to almost nothing.

Four things, and any of them can change the answer.
how metal roofing is installed sets out how each quote is built.
When you hold the roof long enough for the second shingle replacement to land. Asphalt commonly runs 15 to 30 years and standing seam 40 to 70, so a metal roof frequently spans two shingle roofs and their two tear-offs.
Before roughly fifteen years of ownership the gap is real money you do not get back. After thirty it usually reverses. Between the two it is close enough that preference reasonably decides it. how metal roofing is priced compares the systems.
For standing seam against architectural shingle, roughly. For exposed fastener metal it can be near zero.
Slightly in percentage terms, since fixed costs spread, but in dollars a bigger roof means a bigger absolute gap.
Many roofing companies offer finance. Compare the total cost of credit against simply choosing a less expensive system.
