So, here's the shingles on the rear ridge (and a god look of what the old shingles looked like).
And here you can see the tar paper down (this is after one day of work).
The next day they had the new shingles up (leaving the edge exposed to install metal later).
The other end of the house.
The third day they replaced some venting and solved two problems at once. The bathroom exhaust was just venting to the attic while the sewer was venting fine, just leaking and collecting water. So now there are two sewer vents.
And two vents for the bathrooms.
Inside you can see where one of the sewer vents leads to the roof. The old set-up had a large up-hill climb for any water that came in the vent.
Plus the water would sit in a idiotically installed 4-way connector with a cap on the bottom.
A view of the bathroom vents.
And a general view of the attic center-line.
And, let's not forget the head foreman for the job.
