12 Signs You Need a New Roof (Not Just Another Repair)

Twelve specific, verifiable signs your roof is past repair — from granule loss to attic daylight — with what each one really means.

Contractors selling replacements and contractors selling repairs will each see what they want to see. These 12 signs are objective enough that both should agree.

Exterior signs

1. Curling, cupping, or clawing shingles across multiple slopes.

2. Granules filling the gutters like coarse sand.

3. Bald spots where the asphalt mat shows through.

4. Missing shingles after normal (not storm) wind.

5. Sagging ridgeline or dips between rafters.

6. Visible daylight at the roof deck from inside the attic.

Interior signs

7. Water stains that reappear after a repair.

8. Mold or mildew smell in the attic.

9. Frost or moisture on nail tips in winter (ventilation failure).

10. Rising energy bills tied to attic temperature.

Systemic signs

11. Two or more legitimate leaks in a 12-month period.

12. Roof past 80% of expected lifespan for its material and climate.

Frequently Asked Questions

Do I need all 12 signs to replace?
No. Any three from different categories (exterior, interior, systemic) usually justify replacement.
Is granule loss always terminal?
No — new roofs shed loose granules for the first 6 months. Persistent heavy loss on a 10+ year roof is terminal.

Deciding between repair and replacement?

Price both paths side-by-side, then use the insurance guide to know what your carrier should cover.
