If you’re unused to the look of the architectural shingles it can be deceiving. Could have had a bit more stagger on a couple of courses but it doesn’t look botched to me.

I’d be more pissed about the vent flashing. Now is the time to get those installed before the shingles settle in more. Doesn’t look to me like they installed on top of the old roofing. As has been said, it’ll take a while for it to lay down completely and those small strips are part of the design. Basically it’s a second decorative layer on top of the main sealing layer of shingle. There’s a full sheet under the top random tabs.

Arch. shingles on my garage now for 15 years. They have the same smaller strips in various places.
No problems with any of them yet and my place is on a hill and gets lots of wind.

Find another roofer to come and look at your roof and verify if it is properly installed or not. This is one of the reasons why whenever I have work done, I try to be present to make sure they are doing what I expected. I have caught many a contractor trying to screw the pooch on a job.

That's just a crappy installation .... period.

I think it's the design.
If you pick a row and move it over so the lines are farther apart, it lines up other lines.
The narrow ones as well. I don't think they cut those, they are part of the shingle.
I guess your roof is "styling", although not to my liking.

I've warched many roofs redone in my 'hood the last ten years.... that one is a POS installation.

....and I am NOT a pro :)

This roof does not seem to have roof "jacks," unless they are on the front side of the house (unlikely), but it appears to have a ridge vent, which is much cleaner looking and which I prefer. It does not need roof jacks, but the sheeting should have been patched where the old roof jack were removed.

Highly unlikely that this would be a warrantied roof unless the old roof was fully removed. Singles over existing shingles.....just say No.

The stacks do not have boots, and I think this is a bad thing.

If the shingles are properly staggered and properly attached, then this roof should not fail prematurely.

I disagree with some of the conclusions here. Those narrow strips are deliberate. They are decorative panels atop the actual single, which is a single piece. The edges will settle down over time and lie flush. I think boot flashing needs to be added to the vent stacks, personally. But again, if the shingles are properly staggered and attached, then this roof is generally good to go.

They look like normal architectural shingles to me.

I think it's part of the "patina" craze that hit the car hobby a few years ago - spend a lot of money to make something look like crap.

What is the benefit of architectural shingles???

Only cosmetics?

Does the wind get under and lift them???

This is new to me. But my roof is all metal vertical planks

^^^ When they were building my garage, the boss asked what type of shingles I wanted.
I didn't know so I just told him 'ones that would stay put'

He said architectural shingles are better for that....so we did that.

If that was a complete tear-off, the shingles should lay pretty flat. If the building code in you area allows multiple layers of shingles, (we can have three layers here in PDX) then the new roof will telegraph whatever fluctuations the old roof has.

The lack of flashing around the vents is problematic. I'd want to hear what the installer says about that.

neighbor did a significant remodel when I was in the Bay Area and had a very expensive slate roof installed. the design had a half dozen or so colors of slate to be installed. the dumb asses who did the work did not install them randomly enough so there were bunches of concentrated colors all over the roof. it became a running joke in the hood that it looked like it was set up to play twister on.

Normal 3-tab shingles look thin and cheap. If you buy 50 year they are good. Will last about 20-25 years if kept clean and not pressure washed of walked on much.

"Architectural" grade is just a stupid name by marketing people to give the roof some texture, e.g., wood shingles. They are usually 50 year as you're paying a premium to begin with.

I'm on the fence as to how they should be installed, lined up diagonally or random. Getting it right in both cases takes experience.

NO one should cover over an existing roof with any fiberglass shingles. I've seen FG over wood and it can't get any worse. If I were Baz I'd accept that roof as an average install. Not great but probably keeps the water out. No proper stack flashings so the company is substandard to begin with. But there are retro boots.

They probably will conform to the underlayment (whatever it is) after some sun.

I agree with 930Rocket and Vinman about missing vent boots. Baz, I had the GAF HD architectural shingles installed after removing old ones (note what IS300 asked). Something is wrong with the spacing but I can't explain it.

Can someone post pics of how it should be done so I can get an idea of the perceived problems with the OP photos?

I do see some spots where it looks like there's some bumps. I agree that those small tabs seem to be a normal part of many shingles these days.

I personally like the appearance where the sizing is uniform throughout as (but some of them have a bit too much color contrast for me):

This example has the less uniform sizes and more contrast coloring (laid with the smaller strips). I personally would not do it that way, but it is a commonly accepted pattern. I think it looks ok on houses from a distance (two story) but not up close on one-story ranches:

To me, the small tabs just look like poor planning/trying to save on shingles.

If those vents are solder flashed properly and step layered into the comp shingles like I suspect then I don't see a need for roof jacks. The singles come in panels and happen to be cut that way, I don't see a problem. And they will all settle down flat with the summer heat.

@greg, do you see any steps? I can't from his pics.
