Autonomous AI roof monitoring for homeowners and insurers

Our Story

Sentinel was born from a personal nightmare no homeowner should face.

My journey with Sentinel began long before the company existed. When I was younger, Hurricane Katrina destroyed my home in Diamondhead, Mississippi. It took three long years, and a difficult lawsuit, before the insurance company finally paid for the damage. That experience left a lasting impression.

Over the past two decades working in roofing and insurance restoration, I have witnessed the deep distrust that exists across the entire industry. Homeowners often feel that insurance companies and contractors are working against them. Contractors feel squeezed between homeowners and insurers. Insurance companies, in turn, are constantly on guard against fraud. There has been fraud on all sides, but there have also been countless legitimate claims that were unfairly denied.

Sentinel was created to change that broken dynamic. We developed Sentinel to bring objective, time-stamped, fraud-proof evidence to every roof claim. By combining advanced sensors, swarm intelligence, and automated claim documentation, we give homeowners, contractors, and insurers clear, undeniable data they can trust.

Homeowners needed more than insurance.
They needed a guardian.
