All commercial flat roofs have 1 thing in common, drains. if the drain is not functional, then it causes leaks, eventually a replacement. Installing a catch basin will eliminate most of all flat roof issues.
A catch basin collects debris from the entire roof in a small designated area. But, that is not all. Because the drain outlet is several inches lower than the roof, it allows water to flow out freely, without flooding the entire surface, even with all the debris in the basin.
This is a very important part of any flat roof.
