DEAR BARRY: The contractor who built my house failed to slope the flat roof. Whenever it rains, there are pools of standing water on the roof. According to the building department, the roof should be sloped 1/4 inch per foot so that water will drain. The contractor has ignored all of my letters. What can I do? –Robert
DEAR ROBERT: The 1/4-inch-per-foot minimum requirement for roof slope has been the standard in the United States and Canada since the first issue of the Uniform Building Code was published in 1927. It would be difficult for any licensed contractor to deny knowledge of this basic, well-known standard. In short, any builder who constructs a roof without providing minimum drainage is without excuse.
