They could be an Owens Corning Berkshire Collection, or the Old CertainTeed Carriage House collection. (in wich case, cuz of re-cycleing, you`re at the mercy of someone with a surplus)

Alot of Roofing companies make changes to sell new.( or prevent patching )

That Shangle, probably has a clear strip of plastic on the backside for inspectors/Reps. to identify the shingle information. You can`t see the print unless you put it under a special light. (maybe)

I live in the Boston area and know that some roofing companies have location around the country choices of product. Have you searched that option ?

Check out www.certainteed.com.

You can enter your zip code to determine if Carriage House is available in your area (and also find a contractor, if needed). Good luck!

The Carriage House shingle has squared edges.

Me too, have been unable to find. There's some company from china called alibaba.com that shows them but didn't really spend much time investigating the website. GAF has a country mansions ll that has some scallop but they are discounting (I just checked with the lumber yard yesterday.) the country mansions and the certainteed carriage house are what they call luxury shingles and are close to $200 a square. I am looking for red.
