This is supposed to be a brand new roof, and it is because this was a re-inspection. The previous roof looked awful. These shingles appear old. My guess was maybe these were improperly stored for an extended time. Any thoughts outside of just crappy workmanship.
They look like blisters to me.
Blisters are now usually formed when volatiles flash out of the asphalt in newly installed shingles . This is caused by excessive heat from poorly ventilated and over-heated roof systems. … Even though blistering is often perceived as a manufacturing defect, it’s usually caused by poor ventilation of the roof system.

Or, manufacturer’s defect… 
Do you have a sharper image, Darrul?
Very ugly! Maybe some ‘seconds’ you get from the discount builder supply store?
I have not seen shingles fresh from a box but don’t they usually come with loose granules that wash off when new? Is what we are seeing this extra layer of loose granules and it just looks weird? Did they knock off easily?
That’s what I think. The roof is maybe a week old
Granules were kind of clumped
Those might be brand new then. Hopefully someone else will chime in but that is what I understood to expect on new ones which is why you find granules in the gutter after a new one is put one.
They look like ‘seconds’.
Blisters, granules or seconds, they sure aren’t satisfactory.
But, were they loose?
Stevie Wonder roofing …
Wondering alright. Hey, maybe it’s a new antique blistered look shingle that just hit the market that we haven’t seen yet. LOL
No they weren’t loose. We’ve had some really cold weather lately & most likely it was freezing cold when it was installed
The sure look like blisters to me. Maybe they were returned and this poor roofer got them shipped to him and, of course, they hired the cheapest roofer that didn’t know any better. LOL!
Wow ! That’s a mess alright…
could you let us know more about the roof , the slope, existing ventilation , and approximately how warm it was when the shingles were installed, and any idea how long the old shingles lasted?
I see in the pics where it looks like they had a 2/6 nailed to the roof to work with …as the faint line across the shingles kinda indicates .
I have seen shingles that were stored for many years, then installed, deteriorated noticeably faster than others .
It also looks like at the bottom edge of some of the shingles are damaged by exesive work boot type traffic … as using shoes other than soft soles really mess up a roof quickly.
I’ve seen Crazy Roofers installing late winter , with frost every morning and I bit of snow too if memory serves. I’ll have to take a look at that roof now , come to think about it , I would think the shingles would have a tendency to crack or shatter in the cold… You would not catch me on a roof with any noticeable frost … gravity works to fast …
Blisters that have not had their caps weathered away. Probably caused by being stored under excessively hot conditions.
Blisters are not functional damage, but in most jurisdictions I think this would be covered under the contractor’s warranty and possibly under the manufacturer’s warranty, depending on the terms.
Sorry ! ... my first posting... and put it in the wrong area below a number of messages ago .

Since were here in Michigan it couldn’t have been more than 25F when they installed this roof. The previous roof had soffit & gable vents. The soffit vents were all blocked by insulation & still are to this day. They did install a couple of can vents this time as you can see lol. The pitch was like 4:12 or less. Not sure how long the previous roof covering was on. There is also HVAC ducts that run through attic & leak like crazy at the connections
Thanx ! It’s always nice to get an insight into things like that , makes us all learn and better our understanding with issues.
If the installation is only a resend job, I would have to guess a novice installation crew, the helper with hard soled work boots damaged the shingles. I noticed I did minor damage myself years ago, with my hiking boots , on my own garage .
Darrul,
