I have a customer looking to recreate the look of his existing 1920’s wall shingles. He has chosen an asphalt shingle by CertainTeed. I checked with the manufacturer for install info on addressing inside/outside corners,etc… on a wall shingle application. He said that they do not have any info for installing on walls but directed me to the “steep pitch” section of the manual. I found some info there but am still left with ideas of how to address the corners. For example, I plan to treat inside corners much like a roof valley. With a membrane, housewrap/underlayment and metal flashing. I am wondering if I can wrap the shingles around the outside corners the same way the existing were installed. But that might not be too cooperative given the winter temperatures. If possible should I attempt to wrap the shingle around the inside corners as well too? Any feedback from installers who have used asphalt shingles on exterior walls would be appreciated. Thanks.

Bring the shingles up to trim boards?
You need corner boards and about 8 nails per shingle, properly placed to avoid sagging when these warm up.
IMO, this whole idea is a disaster in the making. Much better to use cedar shingles
I agree and have my concerns about the job as well. Why do you say that its a disaster in the making. Just want to hear your take on it.
The homeowner is pretty set on wanting to recreate the look the house has now. Kind of funny because it's not even the original siding material. There is wood lap siding underneath it that could be salvageable and these shingles were added somewhere around the 20's. The old shingles wrap around the corner but I'm not sure if the CertainTeed asphalt shingles will want to do that.
You need to find the right craftsman for this, I suspect. I've seen roofs shingled to look like an English country house with a thatch roof -- all curled along the edges, etc. I'm guessing it takes some creative work with a torch to bend the shingles to the right shape. Probably better done with organic vs fiberglass shingles.
Several reasons to say it.
One is that these shingles do NOT look good up close and in your face, which is where they wil be for a siding aplication.
#2 is that when YOU even feel a need to ask, it suggested to e that you were inexperienced with them and might find it difficult to apply them with any hope of making the job look good. Esp with ref to the idea of wrapping in and oput, but I see that you realize that one is a losing game from the start.
#3 is that while HOs often demand something, when they get what they want, if they do not like it, the fault is all the installer's problem. Today's HO are more demanding thban when overlay recovery shingles were designed for cover over applications like this. And you already have a strong hint that the companywill not be of any help in convincing the customer that you installed them right.
#4 I know I could do twice asd good a job with real cedars for very little more money and I am predjudiced to use the real thing.
If someone came to me and was convinced that is what they wanted, I would have to tell them, how happy I was for them and that they could surely find someone to to do it their way. I used to believe that in every situation the customer is always right, no mater how wrong they are.
But I have learned to change that in my old age.
The customer is always right, no matter how much it costs him to prove it to himself
