good news and bad news

First the good news: Except for one itty bitty thing, our roof is actually fine, and functioning as it should - keeping rain, sun, and pigeon poop out of our house.

The bad news? The roof of the house adjacent to ours (damn rowhouses!!!) is not functioning as it should, and this is why water is getting into our house.

I'm not sure this homeownership thing is all it's cracked up to be...
