1: Loss of minerals granular exposes the thick bitumen layer and mat. Thanks.
Observation: Single Wear, Cracking & Granule Loss.
2: Hear is what I read about exposed ABS plumbing pipe.
Some local regulations require ABS pipes to ‘contain pigments’ to protect it from UV radiation or to ‘be painted’ with latex paint. Exposed ABS goes in my reports the same as exposed ‘cast iron’ vent pipes. Observation: Missing pipe flashing.

Kenton, maybe its just me but, look at ‘all the wide slots’ from shrinkage on the roof deck, not only the wider slots due to course alignment/correction.
With racking, I would expect 1,2,3 courses required correction. The wide slot would be on one side of the shingle, not at both ends of the shingle.
Likely shingle the installer was installing seconds and used chalked lines to keep the courses in line, but again did not install the roof.
Story. When I was roofing, IKO manufactured shingles in Quebec. The government of Quebec warned the company several times about quality control due to consumer complaints. The company was fined and told make improvements. They moved ><30 miles West to an Ontario border town instead of updating the Quebec manufacturing plant. When we installed shingles, we being the company and men I worked with, you chalked squares vertically and horizontally. You being me, or anyone with the sense. Lol. You/me/us/we would watch as poorly manufactured shingles deviated away from chalked-lines. Quality control was out of control. Lol. Started using Domtar and BP roofing products after that.
