Roof Drain Pan SCP Purpose

The purpose of roof drain pan SCP is to sump ot lower the single plate combination roof drains and also sump the individual single flat roof drains. This makes them the lowest point(s) on the roof. This will draw the standing rainwater into the sump pan and the flat roof drain effectively eliminating major ponding area(s).  


INCREASED  EFFICIENCY:  The unique integral sump feature easily lowers both of the roof drains two inches below the flat roof deck surface making them the lowest point on the roof. Being the lowest point on the roof, gravity then pushes the rainwater into the sump pan and thus the roof drains.


Further, the combined surface area of the sump pan and the flat roof drains will increase drainage capacity over a standard sump receiver. 

Sumping a roof drain is vital if you want to maximize your roof drains potential and eliminate standing water on your flat roof. 


This versatile sump pan can be installed on a wood, metal or concrete roof without extensive modification to either the roof, the sump pan or the roof drain, with the exception of model LCP.
