An update from on top of the house.
First, an image of the yankee gutter, the internal gutter system that involves cutting in to the rafters to make an indentation for the water. It’s an interesting idea, but if there are any leaks at all you don’t get leaky gutters – you get a leaky roof.
Once the old metal was taken off, all the rafter tails under the yankee gutter had to be sistered with new wood.
Except for that, the boards were in good shape. From inside the attic, with no sheeting on yet:
From across the street. They had to cut up the rolls of sheet metal to get it off the roof and into the dumpster.
