According the the installation instructions for the shingles (Certainteed), the starter row is supposed to be a regular shingle with the bottom 5" cut off (or you can buy them pre-cut like this).
I spoke to the contractor before hiring him, and asked if they install according to the manufacturer's instructions. I also specifically asked about the starter course. He said that's the only way they install. They buy the special starter shingles, and install according to the manufacturer's instructions.
That's all well and good, but the crew that did the work didn't do this. They just used a regular, full shingle, upside down.
Since this is not in accordance with the manufacturer's instructions, it puts the warranty at risk.
I also suspect they didn't apply Winterguard where they said they would (the entire rear dormer) and they didn't add soffit vents. He also said they'd remove the siding so they could get the Winterguard up the side there too, but I have seen no evidence of this. The drip edge is the wrong color (silver instead of white) and they didn't replace the vent pipe flanges.
Here's some pictures. Please let me know if you see anything wrong.
How much of this a big deal? How do you fix it? Could fixing the starter course cause more problems than leaving it alone?
