Flat roofs are more often troublesome than not. Most of the time the roof is so flat that there is no pitch to the roof and therefore water ponds on the roof with no place to go.

BP Gas station retained our services to install a roof drain to divert the water that had been ponding on the roof. Not only had the plumbing needed to be done for a new roof drain but the existing roof area needed to be addressed as well with a New GAF Roof .
