* 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 roof drain sump pans we purchased from Jim at Roof Drain Pans lowered the roof drains and no more standing rain water. They work great!!  M.V. property owner.  CUSTOMER TESTIMONIALS
