Our valued customers love using their flat roof drain pan
I just received my first roof drain sump pans and roof drain from Roof Drain Pans co and installed them the same day. I accomplished in 45 minutes what would have taken me 3 or 4 hours! Major time saver and paid for the products many times over. Fast and easy to install just like it says. I'll be back for some more....

These roof drain sump pans do exactly what is said will do. Find your low spot, drop in the assembly, connect piping, seal it up and the standing rain water disappears. Flat roof drainage issues GONE. Fast, easy and cost effective.

The roof drain installation video is well done!
This video is fantastic & well done. I just left a flat roof we installed 10 years ago & if we would of installed these flush roof drain sump pans, then we wouldn't be repairing the drywall ceilings below for the last 4 years. Thank you for your video.

It was an absolute pleasure working with Jim at Roof Drain Pans Co.He was able to rush product and have it sent out immediately which allowed my framing process to be completed super quickly and efficiently - without any downtime. The product is great and service impeccable. Would highly recommend!

Hi Jim here are a few pictures of my final product, it is connected to two 3in PVC pipe inside the soffit and slid normal gutters over them. Love the drain will for sure be getting at least 2 more in the future.
We have had a few rains since finishing it and the water flows to it and it drains great! (see pix on the projects page)
