i would much rather use roofing nails to attach the bottom part to the roof.
anyway, the flashing is so easy to cut with tin snips. remember, start at the bottom and overlap going up the hill. Use plenty of Butyl Rubber Caulking.
Good Luck on the new product, maybe someone else has heard or seen this. I have not, so much in the roofing industry has never changed over the years.
