Claim 11:
12. A roof scupper overflow, consisting of:
a base plate having a center opening for fluid communication with a drain and an inner edge for attachment along an edge of a roof;
said base plate supporting a frame;
said frame including a slidable housing in cooperative engagement therewith;
said slidable housing including a sieve tray supported by said base plate in cooperative magnetic engagement therewith;
said sieve tray comprising a sieve plate including a plurality of teeth projecting from a periphery thereof and a plurality of perforations therethrough;
said slidable housing including a foam buoy secured between opposing side walls and a top flange and spaced apart aligned side flanges;
a vertically positioned screen contiguous to said sieve plate and spaced apart a selected distance from the inner edge and affixed to an inner solid portion of a surface of said sieve plate;
said foam buoy comprising a foam material having a lower inner wall portion attaching to an upper screen portion;
a WIFI magnetic sensor module supported by a pair of spaced apart aligned module support arms; and
whereby rising water floating said foam buoy raises said sieve tray and said screen breaking a magnetic connection between said sieve plate and said base plate and sending a signal to said WIFI magnetic sensor module to notify a user of a water overflow condition.
