How to shingle hips the peak of a roof.
Installing ridge cap and hip shingles on the hips you ll start at the bottom trimming the first piece so the corners of the hip shingles don t extend into the gutter.
Trim the very last shingle on each ridge as needed.
The guys would cut a second shingle to overlap the back half of the first one.
Overlap them as before and continue until you reach the top.
Overlay the first shingle with the next nailing in the same manner as for the first shingle.
Bending and overlapping these flaps the guys would put two more nails to anchor it in place.
Repeat this until you reach the topmost ridge and then repeat for every hip ridge.
That s how the guys.
The hip shingles continued all the way to the ridge and that last shingle was cut to length so as to avoid covering the open ridge rafter.
Determine the width of the shingle pieces and snap a line a little less than half that dimension on one side of the hip or ridge peak then align the side of the shingles along that guide.
Then finish by placing the last caps at the very top of the roof.
For trapezoidal roofs measure the bottom edge the top edge also known as the ridge and the distance between the 2 edges.
If the roof has a triangular shape stretch your tape measure along the bottom edge then measure from the peak point down to the center of the bottom edge.
