Is a structural engineer necessary?
I am adding approx 1200 sq ft to our 1978 built Stockade style (verticle logs) Boyne Falls Log home. Upon doing some reno of the upstairs master bedroom (house is a story and 1/2) I discovered the second floor is on 2X4's. This makes me nervous as my kids bedrooms are underneath.
We will be doing either a two story or a single story reno with a hip roof tied into the current roof. Is one of these options less of a load on the roof?
I also thought about doing a self supporting squared hip roof and doing just a corridor walk way/library shelves between the old and new. (on either 1 or 2 levels).
Am I just paranoid since I hear the logs/wood always creaking away or do I have a consern that deserves the budget for a structural engineer prior to building. We are using an architect for the plans but he is dealing only with the new and transition areas.
Thank you for your educated responses in advance.
