When water is allowed to sit on the flat roof there are several problems that can occur. Flashing can come loose, gravel can be washed away from shingles, nails can .

The Flat Roof Maintenance textbook introduces roofing, including flat roof systems and various types of decks. It examines insulating and water-proofing materials, and techniques of application. Next, it discusses roofing damage, how to repair roofs, and how to make a proper roof inspection. It also explains types of preventive maintenance, how to plan preventive maintenance, and how to select. Roof Drainage. As your roof’s slope sheds water, your roof’s drainage system disposes of it. And, an inadequate drainage system will cause many of the same problems that improper slope will. Whether you’re using internal drains, scuppers or gutters and downspouts, the roof drainage system needs to be matched to the size and slope of your.

Where a built-up flat roof is located above a steep roof, the proper detail is to provide a gravel stop at the top and a counter flashing that extends down over the steep roof for several inches. If the slope of the steep roof is relatively low and wind-driven rain is a risk, a base flashing can be provided that extends from the flat roof.
