Scuppers and Drains on Flat Roofs-Wilton, Darien to Greenwich

Scuppers are drain outlets on the edge of a roof.

Open end scupper
Scuppers are roof drains on the edge of the roof. The best draining system for a flat roof.

Our service is from Westport, Darien, Stamford, Greenwich, New Canaan, Ridgefield, Wilton, and Redding.

The outlet can be just a deep channel with a spout like an outlet or can go through a wall section. Most of the times a scupper will lead water into a leader header. The best draining system is to have a wide scupper and water free fall to the ground.

Closed end scupper
Some scuppers are tied into a downpipe like this one in the picture. This type is not very effective because they clog easily with debris. It has a hole instead of an open mouth.

The best draining system is to have scuppers along the edge of the roof that let the water free fall to the ground.

Benefits of a scupper:

  • If it is wide enough, the scupper will not get clogged with leaves.
  • With rainstorm debris and leaves get washed off the roof
  • Low maintenance
  • Inexpensive
  • A roof will not get flooded as in a drain or gutter

When a scupper is connected with a downpipe, the chances are it will freeze during winter and not drain any water.

These type of scuppers are not very practical because they get clogged with leaves and debris easily.

Large scupper
This is a Small flat roof with a wide mouth scupper. This will never clog up with leaves. This is the best type of scuppers because it has a wide opening to allow debris to wash off during a good rain.

The copper scupper on this small flat roof is very efficient. It is full and water shoots over the edge of the roof.

Flat roofs that are designed to have scuppers as a drainage system are almost maintenance free. Open end scuppers allow for debris to be washed off the roof, unlike a drain or gutter that get full of debris.

Scupper wide for a flat roof
Wide mouth scuppers are the best for draining water off a flat roof. Debris and small objects will not get stuck.

Notice the scupper we installed is twice as wide as the supper in the top picture. Leaves and debris will be washed off the roof in a rainstorm.

Decorative scuppers may have some appeal but are not always practical.
