- 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.
Go To Pin - 2pipe boots are dry rotting and cracking
As you can see in all 3 of these pictures, the pipe boots on the roof are drily rotted and cracking. All of these should have been replaced several years ago. This is done during every new roof install.
Go To Pin - 3More shingles sliding down the roof
The same things are happening in pin #1 here. Nails are high, allowing gravity to pull the shingles down the roof and letting the nails cut through the shingles.
Go To Pin - 4incorrectly installed hip and ridge shingles
Not only are these ridge cap shingles the wrong color, but they are not ridge cap shingles at all. They are just cut-out pieces of ice and a water shield.
Go To Pin - 5incorrect shingle stagger.
The red lines show where the stagger is at. See below for the correct stagger on a house we just finished.
This is the correct way a 6-inch stagger should be installed on a roof. It makes the whole shingle roof a solid congruent unit.
