According to Patterson and Dr. Mehta, “In this edition, we are responding to an unprecedented change in roof drainage design from what has been used for more than a half century. Until recently, the plumbing codes assumed that the flow through a roof drain is the same as the flow through a vertical leader of the same diameter. Several investigations and roof-collapse forensics have shown that our assumption has been incorrect.”
“This monograph has been written as a textbook to serve all three disciplines—architecture, plumbing engineering, and structural engineering,” said Dr. Mehta. “We have learned a great deal since the 2003 publication and have incorporated it into this book.”
