Roof Venting Question - Urgent


To get a permit, you need plans. The plans should be reviewed, and stamped approved. Do yourself a favor, call a structural engineer and have him review what you have. Im pretty darn sure you need jack studs on the right rafters, as GBR said. You cant install collar beams, they wouldnt do anything. Get a PE

Roof Venting Question - Urgent


I dont know what happened to my last post, but GRB is correct. The first thing this guy should have done, before he removed any rafters on the left side, is to jack and hold the right side. This is done with jack studs and a knee wall on the right. The knee wall would sit on a double plate that carries the weight of the roof down to the first floor ceiling joists, then to the middle bearing wall in your home and to the girder in your basement. Think of how the load goes. The bottom end of your original rafters set on and are anchored to the top plate of your exterior walls. Those walls are tied together with your first floor ceiling joists. Put the tips of your fingers together and push. See what happens? the force is outward. Most of the force in your back rafters is now pushing out on top of the new wall, You need to unload those rafters into jack studs and a knee wall IMHO. Get a Professional Structural Engineer, Please! In many cases, not saying yours, the local BI is not a PE, and does not know squat. Happened to me. My local yocal Bucked my PE, and rejected my plans that were stamped by my PE. My PE is retired from the Army Core of Engineers. The local yocol lost, big time, he couldn't even understand the math! GET A LICENSED, STRUCTURAL, PE AND HAVE HIM ISSUE A REPORT WITH WHAT HAS TO BE DONE TO CORRECT YOUR SITUATION. YOU ARE IN OVER YOUR HEAD.

Roof Venting Question - Urgent


Hello Everyone. Just wanted to thank you for all the input again!! I got a structural engineer. They ended up doing exactly what most people said, put in a knee wall on the other side, and I have a massive beam in the crest of the roof. That unfortunately took up some space, so I was forced to bump out more of the roof so that there would be sufficient access to it. It is a huge pain in the you know where. Project is still on going due to the winter here. Also the builder agreed to do the proper venting we agreed on. It will all come together at some point I suppose. Of course I spent more money than planned, but I suppose that is par for the course these days. Learned a lot during all this, that is for sure.
