Prevent flat roof damage before it begins!

Modern roof materials can stand up to corrosive substances better than before but flat roofs are not generally designed to carry the extreme weight placed on them by large pools of standing rainwater and can collapse under the pressure. "Sumping" the roof drains with these roof drain sump pans will solve the problem and save tens of thousands dollars on damages.

 These roof drain sump pans can dramatically increase production on roofing projects .The pre-fabricated roof drain pan and roof drain can be installed in minutes rather than hours required to build wood boxes thereby reducing labor costs and increasing production.  



 Standing rainwater may contain acid rain and other environmental contaminants that can be extremely corrosive and destructive to the roof covering. Over time, they can completely destroy the roof, requiring expensive repair or replacement. Sump pans eliminate standing rainwater and eliminate the need for repairs.    

Help to eliminate roof collapse

 Standing rainwater can place an excessive load on a flat roof to the point of causing the flat roof to collapse. Installing roof drain sump pans eliminate the standing rainwater and may save thousands of dollars on property damage.  

SAVE MONEY on roof sloping


When you sump or lower the roof drains on the low spots of the flat roof, they automatically become the lowest points on the flat roof. Water will naturally gravitate toward them. Doing this may eliminate the cost of resloping the entire flat roof which is  VERY EXPENSIVE. 

NOTE: This advice does not rule out the need for structural issues and the need to reslope the roof.
