Thompson-Mathis Metal Manufacturing

Scuppers are used to provide an outlet through parapet walls or gravel stops on flat and built-up roofs to allow drainage of excess water. They can be used in conjunction with gutters and downspouts to divert the flow to the desired location.

Scuppers can be installed to carry water into gutters or directly into downspouts through conductor heads. When a conductor head is used, it should be at least 2" wider than the scupper. When neither conductor heads nor gutters are used to catch the water, scupper spouts should extend past the exterior surface of the building to avoid wetting the building surface.

A scupper with a roof flange is designed to be installed from the roof side through the wall, while a tube scupper carries water from the roof through a wall pipe down the side of a building.

When ordering your custom scupper please provide us with the following measurements along with the type of material:

1. Tube size ( i.e. 3 1/2 x 4, 4 x 4, 5 x 6, 6 x 6 for square and diameter for round )
2. Flange (pictures to left ) or tube style.
3. Length of tube to go through wall (i.e. 12” long).

We manufacture scuppers from all materials to your specifications.  Please fax your design and measurements to 214-826-1897 for a quote or complete our online quote form.
