I am looking at an asbestos tiled roof in midwest about 80 years old. Surfaces and edges badly deteriorated in many areas. Some of the shingles are "lifted" along lower edge, oftend have both moss and some other type of debris underneath them at the lower edge. This is occurring at many areas of field of room, sometimes isolated, sometimes 3-4 tiles in a row. Mostly happening on southern exposure, to some extent on western exposure, little to the north or east. They tend to rebound back up again if I press down on them, like a small diving board.
If anyone has seen this and has possible explanations or diagnostic procedure to help figure out what is going on, any help appreciated.
