In this photo, you can see putting in the shingles where the granules or letting go of the asphalt mat and you can also see evidence of nail pops and leaks.

Here, I was able to determine that there wasn’t an OSB or plywood sheathing over the slat boards below the shingles. I was able to take a peek in this patched area over an old vent pipe hole.

In this photo, you can see that a framing nail has worked it’s way loose and is pushing the shingles up. These are likely to cause leaks as well as being unsightly.  Also, the shingles are no longer sticking together at the nail line. The glue has long since degraded. This is called delamination.

In this photo, you can see a chimney that is no longer in use. The fewer penetrations on the roof, the less likelihood for a future leak. In this case, we will take down the chimney below the roof deck surface and cover and patch the hole and roof over the top of that.
