One of the items listed as urgent on our inspection report was putting a vermin screen on our chimney. I have a severe vermin aversion, so this was pretty important to me. The exciting part of the story is that in order to affix it to the chimney, we got to go up on the roof. I'm not sure why, but I didn't expect it to have such a nice view of the Philly skyline. The picture makes it look really distant, but in real life it felt surprisingly close-up.
In order to get to the roof, we had to climb out the office window (pretty tricky) onto this little area, then climb up the ladder you can see in the bottom left of the picture.
Here's the new vermin screen!
