I’m about to replace some rotten exterior corner boards with Azek. I’m not sure what’s underneath i.e house wrap or tar paper. In either case should I cover the corner with anything before reinstalling the new corner trim boards?
Also, I can see that on the end of the house the corner trim board runs under the rake board. Would the corner board on the front side of the house normally run under the soffit or just abut it or will I have to figure that one out when I get up there?

I would make sure your wrap was fairly intact before installing the corner piece - if not cut some new strips and install them first. I'm not sure it would really matter whether you went behind the soffit or stopped at the soffit. From a visual standpoint I think that it would look cleaner not going up behind the soffit. Are you using the Azek purpose made corner boards? or just using 1x or 5/4x Azek?
Thank you for your response. The original corner boards are a 1x4 butted to a 1x5. The Azek stock corners are the same width on both sides so I couldn't use them. I figured it would be expensive to have a corner made to the dimensions I need.
The corner boards currently on the house are not square. Stock AZEK corner boards are square. I'm just going to replace the existing size corner boards with AZEK. The supplier offered to make up AZEK corner boards to the existing dimensions but it would be expensive. I'd like to make up the corners before installing. I plan on installing them as one complete piece, approximately 18 feet long instead of 2 9 footers. I asked the supplier if that was a good idea. He said 'good luck' and have somebody take pictures.
