What is liquid-like roofing tar for?

What is the more liquid-like roofing tar used for? And must it be heated up or will it eventually dry when applied cold?

Mostly for flat roofs AFAIK. You're talking about the stuff in 5 gallon containers? You pour it out and spread it and it dries or cures. Similar to the stuff the pros use when they put it on hot I'm sure. I'm guessing the difference is the pro stuff maybe comes in blocks of hard tar that liquefies when they hear it up in their big cooker.

As far as what little bit I know about tar, there are 2 types, trowel grade and roller grade. The trowel grade works better if it's heated [or hot weather] as it's real stiff when cold. Because it goes on thicker it might do a better job than the roller grade which is easier to apply. Both of them are prone to make you messy.

OK. I thought maybe it might be useful for pouring and filling in tiny places where leaks originate.

I've seen it in 1-gallon cans.

The stuff I've seen in the one gallon cans is quite thick. I've used it before and applied with a putty knife or similar.

"tiny places where leaks originate" are probably better handled with roofing cement in a tube like caulk.
