NDWI Peak Value: 0.64 | Affected Area: 1,050,000 sq ft | Severity: 9/10

CRITICAL FAILURE DETECTED: Widespread membrane degradation with severe dark staining indicating prolonged water ponding and structural weakness. Deep pooling observed across 45% of the primary roof grid. Immediate invasive inspection required to prevent catastrophic failure or active roof collapse. Membrane type: Unknown/Degraded. AI confidence: 99%. Action required immediately.

Hi [Facility Manager Name],

We recently ran a remote aerial analysis of your facility at 2420 E Grand Blvd, Detroit, MI.

THE PROBLEM:
Our automated InSAR tracking just flagged a critical anomaly on your exterior membrane (critical failure detected: widespread membrane degradation with severe dark staining indicating prol...). Because your facility is roughly 123 years old, it is no longer a question of 'if' you have active leaks, but when the underlying decking will collapse under the pooling weight.

THE RISK:
If deferred, you're looking at a full membrane replacement ($28,000,000 - $49,000,000) plus potential interior disruptions.

THE SOLUTION:
We can likely catch this with targeted repairs ($4,200,000 - $9,450,000) if we act within the next 30 days. I'd like to send my team out to physically verify the satellite data and give you a firm path forward.

Copied!
