Torch applied modified bitumen is a much stronger product and the seams will have bleed out of the bitumen,Roll roofing will tear like felt paper and has roofing cement between the laps normally,some might face nail it to.Mop grade will have flow from the mop on the seams, both modifieds may also have granules thrown into the bleed out.Modfied bitumen will look a whole lot better then roll roofing a 3 year product here.

White Torch Down Roofing

Look for the bleed out on the seams which means it Modified. Nailed end laps or horizontal laps usually mean 90lb

4 years ago they cared... :laughing:
Folks get chastised for not using the search function and bringing up subjects already covered before. Then, when someone resurrects an old thread (even from four years ago) because it interests them, they get laughed at by some. :rolleyes:
