Depreciation
The reduction in value of property based on age and wear, which insurance companies use to calculate claim payouts.
How It Works
Insurance companies assume property loses value over time. For roofing, depreciation is typically 5-10% per year. A 15-year-old roof is considered 75% depreciated, even if it still works fine.
This depreciation calculation is used with ACV (Actual Cash Value) coverage. It's not applied with RCV (Replacement Cost Value) coverage.
Why This Hurts Homeowners
A roof might still be functional after 12-15 years, but insurance considers it mostly used up. When damage happens, they pay based on remaining life, not actual replacement cost.
Avoid Depreciation Penalties
Ask your insurance agent for RCV coverage, which doesn't apply depreciation. Yes, your premium increases, but you won't get hit with depreciation deductions when you file a claim.
