- 1Shingles Sliding Down The Roof
In this picture, the shingles start to slide down the roof. You will also notice that the shingles are becoming Unlaminated.
You can see they all fall apart when I lift on these shingles. This is called De-Lamination. The shingles start to separate from one another.
This roofing nail is high nailed. The nails should all be in an area of the shingles just above the tar strip called a nail line. When they are high nailed, they are put in a thinner part of the shingle, letting them rip through or cut into the shingle as gravity pulls them down the roof.
