If you could go across the street and maybe decrease the angle of view to the top of the tower and roof, you could probably see this better.?? Other than that I guess you could wait for some sunshine and a few shadows to use some long forgotten trig to calculate the height of each from the ground assuming the sun shines in a suitable direction.
