I never said step flashing was unacceptable.
One way to do it is you have to fool the city a lil bit.
Put one nail in the stick flashing against the wall,
Pass inspection, then remove it and install step flashing when you install the shingles.
But just wondering how many builders do you know who would pay for stick flashing and step flashing?
I dont know of a single one.
All them are the cheapest bastards.
I can not stand to speak with any of them.
It is always a waste of time.
The only way i roof a new construction house is if a past homeowner/customer forces them to.
