Flat Roof Repair and Leak Maintenance in Unity SK, September 28 2012

Below you will find a field report and site assessment from our flat roof repair crew in Unity for a commercial client. They responded to a call for leak repair and roof maintenance.
Field Report, September 28 2012:
The client escorted us to the ceiling where leaks were coming from, and then we proceeded to the roof. The roof itself contained four different systems: PVC, BUR, SBS, tar/gravel. The leak in question originated from the BUR & tar/gravel section.
We cleaned all the snow around the drain and checked for possible leaks there as well. It was found that the draining pipe was either too small for the drain or incorrectly installed.
This is probably not a roof problem, so much as it is a plumbing one. We gummed the inside of the drain as a temporary fix and advised the client to contact a plumber.
