We were hired to fly our mapping drone over the Grand Summit Hotel in Park City, Utah. The hotel is quite large and is ringed with heated cable (heat trace cable) to keep large chunks of ice from falling off and possibly injuring someone. The hotel needed to replace their roof ice melt system with a new and more energy efficient system and needed to know how many feet of existing cable was up there.
In about an hour we were able to safely fly the drone over and around the hotel getting hi-res images and GPS data which were then passed onto the engineers where they were able to easily get the measurements from the safety of their desks.
We saved our client time, money, and they never had to put anyone in harms way. Using drones for roof inspections just works.
