Wooden Platform
One of the worst roommates on the list paid for a room that they didn’t even use. Instead, they slept on the house roof but this almost had lethal consequences. We don’t know how this was legal but they continued to do it until they almost turned someone into a pancake.

“He would take my couch cushions on the roof to sleep on a wooden platform he built so we couldn’t use the couch,” the Redditor revealed. “One day the wooden platform blew off the roof and missed my friend by about two feet, it probably would’ve killed him.”
