Comfort Akaya Alterations Attempt

In this video, we attempt to repair the shingles on the back slope of the roof. Existing shingles are extremely adhered, so unsealing them to remove just 1 wind damaged shingle ended up damaging actually 4 shingles, (even though in the video I mention 3 damaged). I forgot the 1 below that had material transference, which took chunks of asphalt mixture, and fiberglass mat with the shingle above it when delaminated using a putty knife. Also shingles broke and lost granules just un-adhering, not to mention were broken further and creased when lifting high enough to accommodate the swing of a hammer during the new nailing of the temporary shingles. Ultimately, the attempted alterations proved the roof to be 100% irreparable.
