Building a Fence Around One's Roof

From Halachipedia
  1. There is a positive Torah command to build a fence on the roof of a house that’s used for living, however, a building used for storage or animals doesn’t require a fence on the roof. [1]
  2. Shuls and Batei Midrash are exempt from putting a fence on the roof since these buildings aren’t meant for living. [2]
  3. The fence on the roof must be ten tefachim (86 centimeters) and strong enough so it would prevent someone from falling. [3]
  4. Some say that there’s no obligation for a slanted roof. [4]
