When the rows of shingles reached the penetration, the flange was set in place.

 

The shingles were cut with a pair of tin snips. (This shingle was laid over top just for purposes of measuring.)

 

The first row of cut shingles was nailed in place. The flange goes over top of these shingles.

 

The next row of shingles were cut to fit around the dome of the flange.

 

This row of shingles goes over top of the flange.

In essence, the flange acts like a shingle itself... it lays on top of the shingles below it, and underneath the shingles above.

 

We applied a bead of roofing tar to the edge of the cut shingle.

 

We also applied a bead of tar where the cut edge meets the dome.

 

Another row of shingles.

Some roofers prefer to fill in the black plastic space below the dome. My belief is that putting shingles there only slows down the flow of water and might contribute to a leak someday. I'd sooner leave the area below the dome free and clear so water can exit quickly.
