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....

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.
