Cory, I was under the impression that FL didn't allow the use of ballast type roof systems because of airborne debris that occurs during high winds. Air will get under an E.P.D.M. single ply roof, lift the membrane and create flying projectiles, kinda like a shotgun shell. If this is the system you have, get a shovel, a truck and start sweeping. On larger commercial installations there are companies that will come in and suck all the loose rock off the roof. If you are planning on roofing yourself as a DIY, FL requires tear-off, dry-in and install inspection.
