About this calculator

Roofing is the single largest line item on most inspection reports, and the cost spread is enormous — $300 for a single shingle replacement to $35K+ for a full metal re-roof. This calculator estimates your range based on material, scope, and home size, and flags negotiation opportunities when the roof is at or near end-of-life.

Frequently asked questions

How much does a new roof cost today?
For an average 2,200 sq ft home today: asphalt $8,500–$18,000, metal $18,000–$35,000, tile $22,000–$50,000. Regional metros (CA, NY, MA) run 20–35% higher; rural Midwest runs 10–15% lower. Add $1,500–$3,500 for tear-off if there are existing layers.
When is repair smarter than replacement?
Repair makes sense when the roof is under 15 years old, damage is localized, and the underlying decking is sound. Replacement is the right call when the roof is 20+ years old, multiple sections are failing, or the inspector found decking damage. Patching a 20+ year roof rarely buys more than 1-2 years.
What's a fair seller credit for a failing roof?
The upper end of your estimated full-replacement range, minus 10-20% if the roof has 3-5 years of life left. If the roof is leaking actively, ask for full replacement cost — sellers know leaks are disclosable and rarely fight this.
Should I get a roof inspection before closing?
If the inspector flagged any roof concerns, yes — a dedicated roofer's inspection ($150–$400) gives you specific scope, decking condition, and a written estimate. Use that estimate as your negotiation document.
