Narrative:
I released the brakes when the ramp agent gave me the 'chocks' signal. The airplane rolled backward approximately 6-12 inches. After completing my checklists I went down to the ramp level to check if anyone had been injured or if any damage had occurred to the airplane. Fortunately neither had occurred. I spoke to the lead ramper and he informed me it is standard practice for the ramp crew to not approach the aircraft at [this particular gate] until after it had rolled back! Evidently; due to the slope of the ramp at this gate it is common for the airplane to roll back.
