and fiberglass composition shingles? I have always thought them to be the same thing just one with a cellulose mat and the other with a fiberglass mat. Otherwise they are both impregnated with asphalt and granular surface. The report that I am currently setting up to use in the field has both listed as different choices from roof covering materials.

Peter, the only way that I am aware of to tell the difference is to look at a cross section of the shingle, you will see the fiberglass strands in a fiberglass composition shingle. Hard to tell just by looking after they are installed.

Asphalt Shingles are softer and more flexible than fiberglass shingles, especially in cold weather. They are thicker and more tear-resistant than fiberglass shingles. They also contain more asphalt and nearly always use heavier weight reinforcement than fiberglass shingles of similar weight.
Fiberglass shingles are thinner and more brittle than Asphalt shingles and they show obvious imperfections in the roof deck.
If you?re not sure and you really want to know, just locate an inconspicuous area of the roof, tear off a tiny piece of the shingle edge. If it?s a fiberglass shingle, you?ll see the glass fiber, which looks like fine hair. With the asphalt shingle you?ll see the black saturated mat.

Vandalism?
Please…get real.
Peter,
I always identify both of these shingles as Asphalt shingles. I've never had an issue with the identification as of today. They both contain asphalt, so identifying them as such shouldn't be be big deal.
It's the mat that differs, not the surface coating.

I would make it read "asphalt composition shingles", which is where you started, I believe.
The discussion has been based around the difference between "asphalt" and "fiberglass", that is like discussing the differences between apples and oranges.
First, there are asphalt composition shingles with organic (commonly referred to as felt or rag) mat.
Then there are asphalt composition shingles with inorganic (typically fiber glass) mat.

Jerry’s right on the money. They are Asphalt Composition Shingles. Most shingles produced in the last bunch of years use fiberglass as the mat. And your hands will itch after you cut them if you don’t wear gloves while installing them
