An inspection can be done relatively quickly using an aerial video, without the need for someone having to climb up onto the roof to determine where damage may be.
The guttering at this house was full of plant life where seeds had probably been blown in by strong winds. This was causing flooding issues when it rained, and blockage.
An inspection on a farm house roof showed broken / loose tiling, and holes in the roof.
