How to Purchase a Replacement Cast-Iron Roof Drain

Posted by Hy-Tech Roof


Commercial cast-iron roof drains are often subjected to heavy weathering and regular wear and tear. As a result, their parts—including domes, rings, sump pans, and clamps—sometimes break, crack or rust over time, and need to be replaced.

To purchase a replacement part, you need to know the make and model of your original drain. To start, it is best to look for any raised or stamped part numbers that may be visible on the old ring or dome.

Unfortunately, if the drain has undergone extreme damage, this can be difficult to determine. The good news is there are ways to find out this information by looking at the drain’s color and dimensions.

Below, we’ve outlined the drain characteristics that will help you identify the make and model of a roof drain, which can then be used to purchase a replacement part.
