Abstract: On May 12, 2017, Employee #1, employed by a home improvement company, was engaged in roofing work at a residential building. He carried up a roll of asphalt felt and laid the roll on the roof ridge and the dormer ridge. According to the employee's subsequent report, he lost his balance when a wind gust hit the asphalt felt roll and caused it to roll down the sloped roof and strike Employee #1's feet. Employee #1 fell from the roof, a fall height of 20 feet. Emergency services were called, and Employee #1 was transported to the hospital. He was admitted and treated for fractures of both cheek bones and his nose and a concussion.
