Very Simple Answer!!
They didn't have proper ventilation, this will cause them to curl up when they shouldn't. I've seen this before in my profession.
You can get a warranty claim from the shingle company also. IF there's proper ventilation or even when there isn't some times. What they do is take a sample of two shingles and send it to the manufacturer and most of the time you'll get the shingles payed for and most or some of the labor to reshingle it.

You do not have enough ventilation in the attic. Ventilation is split 50-50 between exhaust and intake. Many people have homes that have paint peeling and solve it by putting on vinyl siding. Or others like yourself think that a shoddy product or installation was done on their home.Unfortunately, the problem may not be the paint, roofing or installation, the house is struggling to breathe!
We bought a 107 yr old Victorian and were wondering why the second floor was 15 degrees warmer/ cooler throughout the year. When tearing off the four layers of roofing we discovered that there was absolutely no ventilation in the attic. I would do a couple things right away.
1) Walk around the perimeter of your home and see what visible vents you may have. This could be louvered gable vents, soffit vents, ridge vents on the ridge of the roof and vents that stick out the top with a fanlike thing.
2) If you have access to the attic space go up and see what is there. Take a flash light, wear long sleeves and pants, and a face mask. You will appreciate this if you have blown in insulation! If you have soffit vents go and make sure that they are not blocked by insulation. You can buy some plastic duct (rafter vent) that will keep insulation from blocking intake of air.
3) Figure out how much area you have in your attic and then figure out how much ventilation you need. More is better than too little. The minimum is 1 sq ft of ventilation for 150 sq ft of attic. But for new construction with a vapor barrier it is 1 sq ft for 300 sq ft of attic space. Just keep in mind a vent that is 4in by 16in does not actually yield 64 in of ventilation it is more like 52in.
Go check out the web and see what info you can get. If the sight of your roof makes you want to cry. You can put a new roof on and install ridge vent. This is considered one of the best ways to exhaust an attic space. We are also looking in to a whole house fan that will help to cool hte house and attic. While you are fixing the ventilation you may want to consider this as well.

The attic of your house is NOT adequately ventilated. If you have ridge vents, that's great, even pan vents are OK. They both work as exhaust vents. But you still have to have air inlets. These are usually air vents in the overhang (Bird Blocks, or Soffit). These are often obstructed by over zealous insulators, If this is the case you will have to clear these vents, or if they're not there you will need to install some. You need air flow under the sheeting of the roof in the attic to prevent the shingles from "curling".

I'll assume you bought the shingles from a reputable dealer. Intense heat causes curl. If you don't live in Death Valley, then I'd guess the heat is building up inside your attic. Is it insulated? Adding gable vents or an attic fan should cure the problem. That is where I would check for the answer.

Are they fiberglass shingles? That is a common problem with fiberglass and the reason most contractors won't use them.
