Since the responses are talking about scuppers, I have to assume that is the problem area.
One thing on scuppers, for anyone's information. Some may think that it may be a design requirement, and some may think that they are not required due to roof drains that are incorporated into the design.
About 10-15 years ago I built a Saturn Garage Dealership in Brunswick, Maine and in the course of the winter months of Construction, heavy snow and rain persisted with cold weather during the January and February months, and one morning I noticed will on the roof to inspect something that there was approximately two and one half feet of snow on the roof and water was entering my boots.
At that moment I realize something was wrong with this picture.
I went down inside the building and tapped on the six inch roof drain and heard a real heavy sound and water was dripping through the dandy clean out of the riser. This illuminated another picture and proceeded to the outfall of this roof leader which was in the parking lot catch basin. It was frozen solid. I went back to the building, called the site Contractor, and drilled a 3/8" hole in the cover of the clean out.
Water shot out at about 35 feet away and lasted for two hours until we had the condition under control.
None should underestimated the importance of scuppers. Their value is priceless. Wether it is in California, Florida, or Maine or Canada, I am a strong believer in scuppers after this near roof collapse, due to design.
