Chloe, more of your great drawing. I want to make a constructive comment: aluminium flashings are not appropriate & highly unusual. This is due to the problem of electrolysis between dissimilar metals. If rainwater runs off one metal onto another, corrosion of the lower metal is accelarated. Zincalume steel flashings are inexpensive, easy to fold & install & compatible with steel roofing. R.K.
