Mike is a FAA Certified Drone Pilot. Some exterior systems and components are inaccessible due to excessive height, roof pitch, wet roof surfaces or fragile roofing materials. A drone may be deployed to inspect inaccessible areas remotely. Drones are very handy tools for home inspectors, but they have their limitations. Drones should not replace "boots on the roof" if the roof system is accessible and the home inspector can safely gain access.
