Summer Roofing 1

I figure I'm gonna be roofing all the time this summer and unless something particularly crazy happens to distinguish a roofing op I'll just use a generic name.
This one was me and Crisis, we were walking around at like 2 in the morning and we saw a yard with a fire escape.
Gear:
me-
Green open (zipperless) hoody
Red sleeveless shirt
Brown cargo pants
Black sneakers
Crisis-
Grey t-shirt
Jeans
Grey converse

We climbed over a spiked fence into the yard and realized we were really exposed, I sat on the bench in the yard social stealth style while a guy walked by. After he passed us we realized how exposed the entire area was (including our fire escape route), so we moved towards a gate in the back of the yard, Crisis opened it quietly and we passed through it, we were in a small alley between a building and a yard.
We move through the yard slowly because the ground there is really loud (covered in some white stuff *shrugs*), and grab onto the bottom of a fire escape and make our way up. We get up pretty quick because most of the windows are dark. On our way up we caught a couple watching South Park and a guy sleeping with the lights on. Once we got to the roof we took a few minute to admire the view and then climbed up a rooflet and hung there for a bit. We heard a weird noise coming from a chimney and listened but realized it must be either mechanical or an animal because it wasn't the kind of noise a person could make (kind of a flexible metal bending sound).
We moved along the roofs up the block until we go to our last roof, this one was separated from the one were standing on by some metal divider that was ankle high but really malleable and loud, Crisis jumped over it and rolled on the roof (too loud by my standards) I took the slow route and went feet first with a lot of arm support to keep quiet. Once there Crisis tests a door and finds it to be open. Later we decided not to go in because of our lack of equipment (no masks, no gloves etc...).
We headed back to the first yard after hanging out in some random lawn chairs. Got out uneventfully after catching some more of South Park.
Crisis tells me about a huge warehouse nearby, sounds like a good op, we're waiting for Cipher to get back then we'll check it out.
Lessons learned:
Don't jump and roll on roofs
Be prepared to go from plain roofing to indoor ops in terms of equipment.
