When you install shingles over an old layer of shingles do you have to put down felt or do you put the new layer of shingles directly over the old layer?
With composition shingles, no felt is necessary between shingle layers. When the exposure of the shingles is the same as the old exposure, the bottom edge of the old shingles is used as a guide for the upper edge of the new shingles in placement. This ability to place the shingles would be lost if covered with felt.
Is there a written standard regarding hail damage to fiberglass shigles in the US?
As far as I know there is not. The type of roof, way that the shingles were installed, age of the shingles, number of layers of shingles, and many other factors all affect how a roof ages. I would suggest that if you are dealing with your insurance company you contact an engineering firm who specializes in this to conduct a study of your roof.
