Water Leak

We have a water leak, we suspect on the unattached side of our brownstone, and have consulted an engineer who said we could probably define where it was coming from by watering the side of the building for an hour with a hose. If that showed no effect we could repeat the process on the back wall and lastly again by flooding the roof. However, we are older women for whom the prospect of hanging over the edge of the roof with a garden hose for the best part of an hour is not terribly appealing. Is there anyone who would do this for us, or does anyone know of another way to test for water. We know that inside the walls are saturated. We have recently had a parapet cap installed (6-7 months ago). We have also recently had the roof patched and it was pronounced in fine shape.
