The use of the snake should be very limited as the wire can be quite heavy when trying to retrieve it as you have the weight of the snake plus gravity fighting you

A scupper allows water to exit the roof, usually into a gutter drain.
Metered roof drains are installed on flat roof systems. Their primary purpose is to allow a small amount of water to drain through them, and allow for water to pool on a roof top. This pooling allows for the sewage treatment plants not to be overwhelmed by the rain water. The metered roof drains must be spaced 50 feet from the roof edge and 100 feet from another metered roof drain. Each metered roof drain has 4 weirs built into its body. By removing weirs you can control the amount of water that will drain. The more weirs removed the faster the roof will drain. The roof must be engineered to hold the weight of the pooling water. More information can be found on the web sites from the manufacturers of metered roof drains. Zurn, Mifab etc.
If you have some Baking Soda and Vinegar, this can be used to unclog a drain. If the drain is really backed up, you could use a wire hanger to unclog it. Simply bend the wire hanger into a hook thin rod with a hook at the end and use it to push and scrape debris out of the drain.
