The newly painted new cedar shingles on a new addition have an extremely rough texture and highly raised grain (on many but not all the shingles). Could this be the result of either that the new siding was left unprotected and unprimed since last fall (in Northern New Jersey) or that the shingles were primed with a latex primer? Or should I believe my contractor who tells me all new painted cedar shingles are like this and that the reason the rest of my house’s shingles are smoother is because they have been painted many times. These newly painted shingles are not only very unpleasant to touch ( you could almost cut yourself on the surface — they’re so sharp), they are also horrible to look at. What is the cause and does anyone know a solution that we can ask our contractor to do?
Also, these shingles are painted white. Can I look forward to this bleeding that I keep reading about?

Whether they continue to bleed will depend on the type of paint used and whether you have any moisture problems behind the shingles in the wall.
Your contractor is telling you the truth. It might seem worse because of latex paint. Any wood grain and roughness will be raised by water. In fact, a technique for creating a smooth finish on paiunted textures is to apply a water based seal coat TO raise the grain and make it stand out hard to stand up against a sander. This is normal for high quality interior finishes but would be prohibitively expensive for a shingle exterior though. I use Maibec factory prestained sanded and rebutted cedars and their product is delivcered in a condition similar to what you describe.
You could sand off the sharp tips and repaint your shingles for esthetic reasons but shouldn't expect your contractor to be reponsible for what is a matter of taste rather than quality, IMHO
*While Piffen may be right on the money there could be other Reasons. 1. As you said it was left unprotected for a long time. This will raise the grain.2. There are several types and grades of shingle. Do you have a box of them left? Where they bundled up in straps? ( these are made to be rough)3. Yes painted shingles will look smoother after a bunch of coats.Who did the work and where are you located? A lot of my work is in Northern NJ and I am Curious.
