What Makes Superior Roof Drain Sump Pans "Superior?"

Quality Engineering Using Modern Precision Laser Fabrication

  • The roof drain pans are fabricated on state of the art modern laser cutting machines resulting in precise dimensions. 
  • High quality 18 gauge galvanized steel is used for strength and durability. They are also produced using stainless steel and aluminum.
  •  This equates to a perfect fit on your roof drain installation project every time and a lifetime of trouble-free service.   

Unique Cutting Edge Design Resulting In "Industry first" Developments

  • Firstly, there hasn't been ANY standardized system for sumping roof drains short of building wooden boxes. (an industry first). A major time saver.
  • Secondly, this new roof drainage system is FAST and EASY to install by nearly anyone. There NO major structural modifications required. It takes the effort out of lowering a roof drain.  Contractors can easily 4x production.
  • Thirdly, two of the four roof drain sump pan models accept bottom or side out roof drains using the same sump pan. No need to buy two separate pans. (Also an industry first)
  • Fourth, two of the sump pan models allow you to choose which roof drain brand you would like to use. 
  • Upcoming developments will allow you to choose any one of the major roof drain brands on the market.

FAST and EASY Installation

I just received my first superior roof drain sump pans and flat roof drains 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.... Eddie, Plumbing contractor.  (New Jersey) 


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