Re: Change 5 ft window to 8 ft atrium door
Hmmm -- the first thing that should be done is contact an engineer to evaluate the structure.
That engineer would then specify the proper support member to be used and whether or not there are wind shears that need to be factored in.
The engineer could advise as to the best way to temporarily shore up the roof load. Possibly the temporary shoring can be done from the inside with a 2 by member on the flat along the distance needed to support however many rafters. From there a 2 by flat on the floor with 2 by's running vertically from floor to the 2 by on the ceiling ---- depending on what's there for loads and what the enginner says..
Once the enginner has provided the signed and stamped drawing ( which is like **** ) you provide that to the building department for your permit.
Once your ready I would suggest you start with the interior removal of the wall covering to expose the structure and to relocate any electrical also any heating pipes or vents.
Then install the required king and jack ( trimmers ) for the new support member. Depending on what the enginner says --- you might be able to insert the new strutural member tight against the the top plates .
Do all the prep work before removing the window to minimize exposing the interior of the home to outside elements.
When the proper shoring is in place and the support members are ready then it's a go to remove the window and cut out the rest of the wall for the door.
Can't stress this enough --- you need to have an engineer come out first.
