There is nothing wrong with flat roofs if you're not a clueless moron like

iggy often shows himself to be.



Around here they slop hot tar onto a couple layers of tarpaper with a mop

and then top it off with a layer of course white rock chips, marble

probably.



If you don't use chips, the tar will crack similar to mud in a dry lake bed.

Connecticut and Illinois are a lot harder on hot tar roofs than Washington is. Extreme heat and extreme cold in both places. The problem with hot tar roofs is that while they are initially cheaper, they are very hard to fix because finding the source of a leak can be a bitch. They are also very messy to work with. I prefer to spend more money and put down a roof that's much more serviceable.

The temp ranges here in Chicago are pretty extreme and any leaks get big
really fast. Looking up to see where the water is leaking followed by a
trip to the roof is going to answer where your leaks are.

One problem with old buildings here is the amount of junk up on the roof.
You can barely even walk around on some commerical buildings because of
all the footings from removed HVAC units, signs, and all the plumbing and
electrical junk related to that stuff.
