When you think of a roof that lasts, metal often comes to mind. Sleek, durable, and low-maintenance, metal roofs have earned a strong reputation in many regions. But when it comes to hail, especially Very Severe Hail (VSH), metal roofing faces a hidden problem. The truth is, not all metal roofs can pass the $80K test.
The Hidden Risk of Hail
Hail does not discriminate. Two-inch ice balls, traveling at high velocity, hit roofs with incredible force. On a metal roof, that sound might be less dramatic than on a membrane roof, but that does not mean the damage is minor.
Dents, punctures, and compromised fasteners may not cause immediate leaks, but they weaken the roof’s integrity. Over time, even small impacts allow water to infiltrate the structure, damage insulation, and threaten interior spaces. The costs can quickly add up, sometimes exceeding $80,000, just like in FM Global’s hail impact studies.
Why Metal Roofs Often Fail the VSH Test
VSH certification does not rely on appearances. It simulates the worst-case hailstorm scenario, testing roofing assemblies under:
- Extreme impact from 2-inch ice balls
- Multiple strikes on seams, fasteners, and corners
- Exposure on new, weathered, and heat-aged metal panels
- Verification of both surface and substrate integrity
Metal roofs frequently fail this test, and not always because of the metal itself. Common failure points include:
- Fastener vulnerabilities. Bolts, clips, and screws can loosen or shear on impact.
- Panel denting. Even minor dents reduce the roof’s ability to shed water and reflect heat.
- Substrate damage. Underlying insulation or decking can crack or puncture, creating hidden leaks.
Without VSH-rated metal assemblies, building owners may unknowingly invest in a system that performs well in appearance but poorly under hail stress.
Why This Matters in VSH Regions
States like Oklahoma, Texas, Tennessee, and Kansas experience frequent severe hail events. For schools, hospitals, government buildings, and mission-critical facilities, roof failure is not just an inconvenience. It can halt operations, damage equipment, and risk safety.
Insurance providers are increasingly requiring VSH-rated systems for high-risk facilities. A standard metal roof without proper testing often falls short of these expectations.
The Real Cost of a Failed Metal Roof
When a metal roof fails VSH testing, the consequences go far beyond cosmetic damage:
- Water infiltration causing mold, corrosion, or contamination
- Equipment and technology damage
- Emergency facility closures
- Insurance disputes and unexpected out-of-pocket repairs
A non-VSH metal roof can quickly become a multi-thousand-dollar liability during the next hailstorm.
Investing in Metal Roofs That Pass the Test
VSH-certified metal roofing systems cost more upfront, but the long-term protection is undeniable. Benefits include:
- Reduced emergency repair expenses
- Enhanced insurance alignment
- Extended roof life
- Protection for occupants, operations, and critical equipment
A properly designed metal roof can withstand hail impacts that would destroy traditional assemblies, ensuring you are prepared before the storm hits.
