[RE-wrenches] Flashed Roof-attachment systems

[Benn Kilburn]

I've been pretty satisfied with the Kinetic flashing/Lfoot and rail system. Their 3" Lfoot results in the rail height being btwn 4-5".  They have other Lfoot heights available. 

I don't have a flashing handy, but they are btwn 8-10" wide. The only potential for a leak path I've ever seen is not a result of the flashing not being wide enough but from not being tall enough, however, this is easily remedied by not locating the base/flashing too high on the course/row of shingles and, if the row is wavy/uneven, having to trim the shingle around the raises portion of the flashing.
