That’s kind of a strange one. My initial knee jerk is that the shingles are a cheap variety, possibly with manufacturing defects. The picture of you lifting the shingles sure look thin and insubstantial.

There are substantial differences in shingle quality, so I’d start there. Orientation to the sun matters a lot. Is this a south facing roof plane? I suppose impact from the snow sliding off the upper roof could be a contributing factor, but those shingles don’t look like they’ve had impact damage; they look like cheap crappy shingles.

Regardless, you need to strip off the failed roofing and install new materials. Lay down a 30# felt underlayment, ice and water shield at the eaves, drip edge around the perimeter, then install an entirely new roof cover. GAF, Certaineed, Johns Manville….all make good shingles, and their materials are among the most trustworthy.

Asphalt shingles are remarkably resilient and long lasting if you use good quality materials and install then satisfactorily. I have to attribute the current failure to lousy materials installed badly, which is always a formula for failure.
