It would appear those shelters (not sure i'd call them hangars) are there to protect from the weather. Wind, snow, rain, hail, etc. As well as to protect against prying eyes above.
Roofs do look so thin that they can't protect even from cluster bomblets. Perhaps they could protect again shrapnel within a bomblet.
Besides, with open ends to the shelter, even a thicker roof wouldn't make much sense.
