it comes in many sizes and comes with glues and flashings and seam tapes .
firestone makes a good one.
also if it is visable you can use ice and water shield and put a metal roof on it.

I have a flat roof that has about 6 inch pitch both ways in 30 feet. I had asphalt SIS on the roof for about 20 years replacing it twice. There were leaks constantly always in a new and unsuspecting place.
What I did is nail down 3/8 plywood to the joists of the roof and install myself .060 Firestone rubber with a 30 year warranty.. It comes in various widths 10, 15, 20 25 and 30 feet wide and is cut to the exact length one needs. Then a truck delivers it and booms it right up to the roof top.
Then I rolled out the rubber onto the plywood and pulled it back and used a roller to apply the contact cement to both side and rolled it back and glued it to the plywood. Something like installing carpeting. The edges are then trimmed off with aluminum trim strips and stainless screws. Really, its a handymans job not some sort of an expertise in roofing.
Sure, there are accesories they sell also like molded rubber stick ons that go around toilet stacks and corners to go around ventilation ducts . Those are available as extra and simply bond down onto the rubber sheet permanently and leak proof.
I did the whole 2000 square foot roof in sections and that has been about 3 years ago. No leaks ever. Its like having an umbrella over the entire house. The cost of me was much less than a tar built up roof. Tar today is like GOLD because it comes from petroleum.
So that is my experience with a flat roof, you are getting it first hand. The cost of materials for this 2000 sq foot roof ran me about $1. 75 a square foot.

Rubberized membrane - its continuous and seal better, especially for low pitched or flat roofs. It will resist standing water.
