This allows water to flow off the upper panels out over the trim onto the lower panels and exits the roof at the eaves. Position the flashing between the two roof pitches. Draw a couple of attached boxes representing a main building plus a building extension. The piece that allows us to join the two different slopes is the pitch transition trim.

They form an upside down v with the point at the top of the addition roof. At the low end of the valley the subfascias of the two roofs are mitered with a block filling in the roof framing. First we should establish the pitch of both roof planes. One is getting the two differently pitched planes to meet at the hip or valley rafter.

Slide the right edge of the flashing under the highest roof pitch. We re going to install it over top of the panels that have already been installed on the lower slope. The easiest way to tie in the new shingles with the old is with a cut valley see four ways to shingle a valley.
