On September 4th, 2025, Knoxville, TN was rocked by a powerful hail storm that left thousands of residents stunned—and their homes potentially compromised. What began as a typical late-summer afternoon quickly escalated into a full-blown weather emergency, as golf ball-sized hail and 60 mph wind gusts pounded rooftops across the region. The National Weather Service issued multiple Severe Thunderstorm Warnings throughout the day, citing threats of property damage, downed trees, and dangerous flying debris.

How Hail Damages Roofs (Even Without Leaks)
Even small hailstones can weaken roof systems, but golf ball-sized hail almost guarantees hidden roof damage, even if there are no visible leaks—yet.
Common Types of Hail Damage:
- Shingle Bruising: The impact of hail causes granule loss, weakening shingles and accelerating aging.
- Cracked or Missing Shingles: Direct hits from hailstones can break asphalt or metal shingles, leaving the roof exposed to water intrusion.
- Punctures or Holes: Severe hail can penetrate the roofing material, especially on older or poorly maintained roofs.
- Damaged Flashing & Gutters: Hail impacts can bend or dislodge flashing, gutters, and vents—leading to water infiltration around the roof edge.
Even if water isn’t entering the home today, unaddressed roof damage can lead to leaks in the coming months—just in time for fall rains and winter snow.
Insurance Claims: Know Your Rights
Many Knoxville homeowners don’t realize they can file a claim for roof damage, even if their roof isn’t leaking. Insurers cover storm damage, not just active leaks.
What You Should Know:
| Topic | Details |
|---|---|
| Claim Eligibility | Most homeowner’s policies cover hail damage. Claims can be filed even if damage isn't immediately visible. |
| Filing Window | Typically within 1 year of the storm—but act sooner to avoid disputes. |
| Inspection Requirement | Insurers often require proof from a professional roofing inspection. |
| Depreciation Recoverable? | Yes, through RCV (Replacement Cost Value) policies. You'll need proper documentation. |
💡 Tip: Insurance companies often deny late or undocumented claims. That’s why it’s critical to schedule a professional inspection immediately.
