Your roof sump pan choice is extremely important and it is sometimes an overlooked roof drain accessory through lack of information. The roof drain pan provides a stable base for the roof drain to rest on rather than just setting it on a plywood deck. Also the metal flanges on each side provide plenty of surface area for the roof material to bond to. This results in fewer roof leaks..

The roof drain sump pan lowers or “sumps” the roof drain below the roof surface. This effectively prevents rainwater from pooling on the flat roof.

A deck plate is often referred to as a TOP SET DECK PLATE by Zurn Mfg. however most roof drain brands have their version. It does not require an underdeck clamp. Eliminating the underdeck clamp makes the installation faster.

A sump receiver is a roof drain accessory that is a flat plate that receives the roof drain. It requires an underdeck clamp to anchor the assembly to the roof.

Like the sump receiver, the common usage is on insulated roofs The insulation can be tapered to the roof drain and receiver thus creating a sort of sump area. The deck plate is secured to the roof rather than an underdeck clamping mechanism.

Like any construction project, it’s all about the planning. If planning goes well, the project is pulled off without a hitch. If not, time is wasted and TIME IS MONEY on any construction project.

Using the wrong roof sump pan can have devastating effects. Consider this : using a sump receiver on a roof with a thin covering causes the roof drain to sit higher than the surrounding roof. This usually results in a huge pool of standing rainwater. This is the exact opposite effect that is being created by a roof drain. It can result in very expensive repairs or premature replacement to the roof and can add roof loads which exceed it’s engineered capability. There are three general types of drain pans.

Roof drain sump pans are not supplied with your roof drain but can be purchased on this website. See which major manufacturer

Blocking your roof drain means installing blocks on the ends of the sump pan that are not over the joists. Often the plywood on the roof is thin and when someone steps between the joists, we have what is referred to as “deflection”. The plywood bends away from the pan and roof drain. This can and will cause leaks. Placing blocks will provide support and prevent this situation. Do this if you have excessive deflection. This photo demonstrates
