Computed decision comparison
Metal roof vs asphalt shingle cost
The modeled upfront totals are $28,963 for Metal roof and $14,431 for Asphalt shingle roof, a difference of $14,532.
Both roof models use a 2,000 sq ft default area. The asphalt side uses the general roof-replacement baseline retained by the existing comparison.

Comparison questions
Which option has the lower modeled upfront cost?
Asphalt shingle roof is lower in the current static default by $14,532. This compares model records, not contractor proposals.
Are 10-year and 20-year replacement costs included?
No sourced lifespan field exists in the shared baseline store, so the site does not invent replacement cycles. Those horizon cells remain explicitly not modeled.
Do both options use the same source system?
Yes. Both are computed from the current baseline store and index snapshots. Any proxy, quantity normalization, or retained legacy factor is disclosed beside the option.
