​​FLAT ROOF PROBLEMS caused by too few flat roof drains is one of the most common problems with flat roofs and often result in the same situation.  ​ ​

​​​​* This video is fantastic & well done. I just left a roof we installed 10 years ago & if we would of installed these flush roof drains then we wouldn't be repairing the drywall ceilings below for the last 4 years. Thank you for your video. Cheers Jeff Myers (YouTube post)
* These roof drain sump pans do exactly what is said will do. Find your low spot, drop it in, connect piping, seal it up and the standing rain water disappears. 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 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

*   Thank you and Jim Jr. for your assistance this weekend. The pictures and instructions for a correct installation were invaluable. E.L. Roofing contractor
WHAT OUR CUSTOMERS HAVE TO SAY .....
roof drain,roof drains, flat roof drain, commercial roof drain

​​​Roof Drain Pans Company has designed, manufactures and patented a series of four roof drain sump pans that are specifically designed to lower a standard cast iron roof drain or double roof drain and overflow two inches below the surrounding flat roof surface.  

​​ROOF DRAINS that are not draining your flat roof because they sit too high create huge pools of standing water, placing a heavy load on the flat roof.  In many cases, heavier loads than the flat roof can handle which could lead to a roof collapse.

THE RESULT is often flat roof structural damage, mold, interior water damage and possible personal injury. Repairing flat roof problems can be expensive and a complete re-roof is VERY  expensive.
