Upon inspecting this roof it was almost immediately apparent that this roof was a victim of high nailing. High nailing can cause the nails to shoot through the shingles or cause gravity to pull the shingles down the roof over time because when the nail is not put in the nail line it gets nailed in a much thinner part of the shingle.

As you can see in this picture I circled the holes left behind by the nails and put a line on the shingle where the nails should be at in the nail line. These holes are way above the nail line causing the shingles to slide down the roof. Unfortunately the whole roof is like this and this is beginning to happen in a lot of different areasGo To Pin
