These roof drain sump pans do exactly what they are supposed to do. Find your low spot, drop it in, seal it up and the standing rain water disappers. Fast, easy and cost effective.  J.R. Roofing contractor: 

Why didn't somebody come up with this idea before now? We will never build a wood sump box again!!  It takes 10 minutes to drop in the small single roof drain and sump pan and we're back to roofing. BIG time saver, pays for itself... L.D. Roofing contractor 

As a property owner, I can't tell you how many thousands of dollars I have spent trying to resolve the large pools of standing rain water on my flat roof with no lasting permanent results. They build up the low area and a pond develops somewhere else. Who does that? The sump pans lowered the roof drains and no more standing rain water. They work great!!  M.V. property owner.
