Does the roof have structural integrity issues? Is the slope too steep? Is the height unsafe? 
That's where a drone can help. Drones can scan, record, and take photos without ever having to send a person into a potentially unsafe situation. With a licensed and insured drone pilot, any unsafe conditions can be avoided. This takes any and all worry and concerns away from the client. A drone can scan most roofs in under 15 minutes. The 4K photos and videos can be used to highlight damages from wind, hail, water, and more.
