This roof is covered with 3-tab asphalt shingles. At the time of the inspection, no signs of defect were observed in the shingles themselves.

There are also signs (uneven shingle colors) that the shingles on the uphill side of the chimney may have been repaired/replaced at some point. I recommend further inspection and repair by a qualified roofing contractor.
