To start the second row, place a shingle above the last shingle in the first row. The shingles should overlap slightly. Repeat the process for until the row is complete.

When you reach the third row, alternate the placement so that each shingle begins in the middle of the shingle underneath it. For this, you will need to precut and size the first shingle in the third row. Lay the remaining shingles until the first slope is shingled.

When reaching a slope change, continue shingling as you have been. The shingle may sit up or stand. Don’t worry, it will fall into place and lay down eventually.

When reaching a ridge, use the roof cap. Lay the ridge cap over the last shingle row. Align it over the ridge then nail it into place.

And that’s how to shingle a gambrel roof. For the best result, do the project on a warm sunny day. The heat of the sun will improve the workability and flexibility of the shingles. In addition, it will allow the tarred side of the shingles to adhere better to the roof surface.
