There are some areas of standing water on my roof, is this normal?

When water stays on your roof, as a general rule of thumb, that’s a bad thing. Any standing water leads to a higher probability of it finding a way to create a leak. When installing flat roofs, we typically construct a positive drainage system which keeps a constant and slight angle to insure that water finds its way off of your roof. Helping water to travel safely down and off your roof is of the utmost importance when considering your roof’s construction.
