I did get a chance to inspect the roof of this church last week. There was no damage to the roof, it is actually in quite good condition since it was installed in the late 80's or early 90's. The leaks they are experiencing are at the flashing transitions to the stone masonry and one at a brick masonry chimney.

But I did want to tell you that I was very impressed with Austin, the young fellow that ran the lift for me. I am not sure I have ever had such a smooth and accurately-placed ride. It wasn't the highest roof I ever had to look at, and maybe the equipment rental was newer, but still, it was refreshing to see the competence of that young fellow.
