Mike holds onto an entire 48-foot sheet of underlayment. With only a light breeze, we decided to try cutting the first sheet off the roll, and lining it up as we stapled it going across the bottom of the roof.

We did the same for the second sheet. Jeff was in charge of handling the sheet and making sure it was aligned while Mike and Paul stapled it down.

Getting ready to lay the third sheet across.

The top side of the underlayment has a skid-proof surface, making it quite safe to walk on. We did not need any 2x4 stringers or roof jacks.

Jeff unrolls the end of the first roll of underlayment while Paul and Mike prepare to staple it down.

Working back toward to the north end.

Laying down the last full section of underlayment before arriving at the roof peak.

Speaking of laying down. Mike's lying down on the job again. He claimed he was "working on his tan."

After the last section was laid down over the peak, the storm clouds moved in, so we quickly nailed down a bunch of vertical 2x4 stringers to hold the underlayment down in case we got strong winds, then Jeff and Paul moved inside to pressure-wash more logs while it rained outside.

The front third of the ridge pole has been washed. Notice the golden color above the scaffold tower on the left, compared to the grayish color of the rest of the pole.

The floor looks as if the roof is still wide open, with all the water on the floor from the pressure washer.

Reaching out to hit the underside of the ridge pole where it passes through the gable wall.

Working on the north RPSL.

After moving the scaffold tower a couple of feet over to the 2nd floor girder, Jeff cleans the top of the second RPSL.
