I haven't been down to my shop since this afternoon, but there's a good possibility some water has gotten in, thanks to the stupid lack of engineering put into the recent road work the city has done. They raised the level of the road a foot above the floor level in the shop, then cut a 24" deep trench, and put an 18" culvert in front of my door. The net result is a funnel diverting water from the road surface into my door. I tried to explain to both the city guy and the contractor how the water needed to run, and the trench, nor the culvert were necessary, and might even cause more harm than good, but they did it anyway. Maybe now they will believe me....
