1Default 1,800 sq ft roof over 50 years
Inputs
Result
Both roofs are bought once inside 50 years (tile lasts 60, metal 50), so the totals are just the installs: tile $27,000 vs metal $19,800. Metal wins by $7,200 and never gets caught — tile only flips later, once metal needs its first re-roof past year 50.
