He is taking this pile, actually two piles of shingles - there is a smaller one behind -- and nailing them to the top of the roof.
Actually I have contracted him, and his crew to do a bit more than just shingling:
- Install the roof sheathing - which is usually 1/2 inch plywood
- Do the on site building of some parts of the roof - for instance, the cricket which crosses the valley between the main roof and the gazebo roof. This is necessary to create a watershed effect to drain water to each side of the roof.
- Install the fascia board, that is the board around the outside of the roof edge.
- Install the chimney, which includes the ceiling support, the flashing where the chimney goes through the roof, inserting the insulated chimney components, and the chimney cap.
- Install the waste vents, there will be two.
- two roof vents
Unfortunately the Cambridge style can not be used for the caps along the roof hips, nor as the starter strip. So an additional 12 bundles of the standard, 3-tab style, in this case called Aristocrat (not shown) are also required.
Valley flashing will also be installed in each of the roof valleys. A roof valley is the place where two roof sections come down and join. The valley flashing comes in 10-foot sections. I was surprised when they arrived rolled up.
Here are the two roof vents, waste vent flashing and chimney support kit patiently waiting to be installed...
