- For tile: has the underlayment ever been replaced?
- Any past leaks, and who repaired them?

- Has there been storm damage or an insurance claim?
When to get a roofing inspection
If the home inspector flags concerns, the roof is older, or the sellers do not have records, many buyers request a separate roof inspection during the inspection period. A roofer can estimate any work so you can factor it into your decision.
