Inspection of the gutters and roof

In these pictures, you can see how badly these gutters are failing. They are in terrible shape and are almost falling off the house. The old nails are missing and coming out of the gutters. Someone has tried to fix this by adding screw-mounted brackets, but as far gone as these gutters are, they should have been replaced long ago.

Once again, you can see how badly these gutters are failing. They are in terrible shape and are almost falling off the house. The old nails are missing and coming out of the gutters. Due to rainwater overtopping the gutter, a decent amount of roof decking is rotted out. This is in several places around the house as well

Lichen is an organism that can live on almost anything but shingles; it can eat away at them. 
  Moss, on the other hand, like to grow along the edge of shingles, and the hair-like root system produces under or in between the shingles. This actually wicks moisture under the shingle, causing them to stay wet, and this will rust out the nails leaving just a hole where the nail used to be.
