How MetLife Calculates Roof Depreciation
MetLife applies a depreciation schedule that reduces the replacement value of a roof based on its age, material, and condition. The insurer assumes a useful life for each roof type—typically 20 years for asphalt shingles, 30 years for wood, and 40 years for metal. Each year the roof ages, MetLife deducts a set percentage from the original replacement cost, resulting in a lower claim payout if the roof fails.

Typical Depreciation Percentages by Roof Age
The following table shows the standard depreciation rates MetLife uses for common residential roof materials. Percentages are approximate and can vary with local building codes or a roof's documented maintenance history.
| Roof Material | Age Range | Depreciation Applied |
|---|---|---|
| Asphalt Shingles | 0‑5 years | 0 % |
| Asphalt Shingles | 6‑10 years | 10 % |
| Asphalt Shingles | 11‑15 years | 20 % |
| Asphalt Shingles | 16‑20 years | 30 % |
| Wood Shingles | 0‑5 years | 0 % |
| Wood Shingles | 6‑15 years | 15 % |
| Wood Shingles | 16‑30 years | 35 % |
| Metal Roofing | 0‑10 years | 0 % |
| Metal Roofing | 11‑20 years | 10 % |
| Metal Roofing | 21‑40 years | 25 % |
Why Depreciation Matters for Claims
When a covered peril—such as wind, hail, or fire—damages a roof, MetLife's adjuster calculates the claim based on the depreciated value, not the original purchase price. If the roof is 12 years old and made of asphalt, the insurer would apply a 20 % reduction, meaning the homeowner receives 80 % of the estimated replacement cost. This can leave a funding gap for repairs, especially if the homeowner has not budgeted for the shortfall.
Strategies to Mitigate Depreciation Impact
Homeowners can reduce the financial surprise of depreciation in several ways:
- Maintain detailed records: Keep invoices, photos, and inspection reports that demonstrate regular upkeep. Strong documentation can sometimes persuade an adjuster to apply a lower depreciation rate.
- Upgrade to longer‑life materials: Switching from asphalt to metal or tile can extend the roof's useful life and lower annual depreciation percentages.
- Consider a replacement cost endorsement: Some policies offer an optional rider that pays the full replacement cost regardless of age, though it raises the premium.
- Schedule a pre‑policy roof inspection: An independent inspection before purchasing insurance provides an objective condition rating that can be used in negotiations.
Impact on Premiums and Policy Decisions
MetLife's underwriting algorithms factor roof age and depreciation into the risk profile. Older roofs with higher depreciation rates typically trigger higher premiums because the insurer anticipates a larger potential payout gap. Conversely, a newer roof or one with a recent professional certification can qualify for discounts, sometimes as much as 10‑15 % off the base premium.
Mobile‑First Considerations for Homeowners
Yuki Tanaka notes that many policyholders now manage insurance on smartphones, so clarity and quick access to depreciation data are crucial. MetLife's mobile portal displays a "Roof Age" field and auto‑calculates the depreciation percentage, allowing users to see the impact on claim limits instantly. When reviewing or updating a policy on a handheld device, look for the "Replacement Cost" and "Depreciated Value" figures side by side; this layout helps you gauge whether an endorsement or roof upgrade is financially worthwhile.
