Info on single tab asphalt shingles

Hey y’all, looking for more information on when single tab shingles were used, discontinued, and any known manufactures. Been googling away but roofing company’s kill the algorithm. Pics for reference [image] [image] [image]

Shingle Identification?

Does anyone recognize these shingles? They look like a standard laminated shingle but instead of pieces being laminated on they are just colored to look like it. I’m going to see it in person tomorrow and can get some better pics but am curious if anyone has ever seen it. Thanks. [Screenshot (221)] [Screenshot (222)]

Shingle Type-help

I have a question about the shingle type on a home I just inspected. Typically, architectural shingles have a very distinct look, these were not installed like 3-tab but did not have all the characteristics of architectural. Am I just overthinking it? Heres a picture. [20200217_125929]

Shingle anomalies

Hello Everyone. I am working on my mock inspections and ran across these shingles on a friends house that I inspected yesterday. It looks like some sort of tar “bleed through”- there are granules underneath. I have seen many shingles in various states but never anything like this. We had a major hail storm here in San Antonio a few years ago that took out a good portion of roofs. This was a total tear off, (to the sheathing) and is about three years old. I wonder if this is a normal occurrence…
