These sump pans were designed by a plumbing contractor to be a FAST, EASY, and COST EFFECTIVE to install. They are designed to work EVERY TIME.
These are such a problems that the Uniform Plumbing code devotes an entire chapter to it.
All deck mounted roof drains should be sumped with a few exceptions*. One of the biggest multinational roofing material manufacturers recommends them. SEE HERE

Flat roof cave-ins from excessive roof loads caused by inadequate roof drainage and the resulting standing rainwater.
Roof coverings destroyed long before their service life for the same reason along with their attendant interior property damage issues including mold growth.
All situations adding up to millions in roof repair or replacement costs.
A common cause for these problems are flat roof drains that are sitting too high on the flat roof
So how will you do that?
Have custom metal pans built? It's generally very expensive to fabricate a quality product and production lead times are generally very long unless you have a very long run. Not to mention the time to engineer the plans and specs.
Build up the roof with heavy gravel or a leveling compound? Will the heavy gravel add more weight and continue to cause the the low spots to sag worse? Will the leveling compound cause the ponding rainwater to move to new low spots?
Install a tapered roof system? Of course there are the tapered roof systems which are required by code in some areas. You can "feather" the tapered insulation to the roof drain to make a sump. But what if you don't need this system? It can be EXTREMELY expensive.
