That is our intention, but what we need to find out is if the sistered beams need to go to? SE seems to be our best bet for answers. Thank yo.
Keep in mind someday when you sell the house structural issues associated with visible fire damage will significantly reduce the number of clients willing to buy it.

Yes that is exactly why we would like to replace the roof and rafters now.
I highly suspect an structural engineer was used by the party, I suspect an insurance company but could be mistaken, that did the repairs. There are collar ties on the newer rafters.
Either/or, the purchaser will retain their own inspector so why payout ones hard earned money again and again.
Well, we absolutely need to re-shingle this season and will need to pull all of the previous planking and replace with plywood (at least that is the roofers recommendation) - it seems like the question that needs to be determined is will the plywood be sufficient given the current supports and lack of ridge? It seems like the consensus here is that we won’t know for sure unless a SE gives input?
I see complete sets of rafters with collar ties were installed.
As for, surface charring. Shou Sugi Ban. Been around for hundreds of years. Shou sugi ban, or yakisugi, is a Japanese wood-burning technique that brings out the natural patterns of wood while also weatherproofing it.
Ridge Beam vs. Ridge Board. Likely Ridge Board. Prone to fire degradation. No structural support.
Likely planks are in good shape to install plywood on.
Retain an independent home inspector/SE.

The plywood will be sufficient. The rafters are the concern. And not all roofs have a ridge beam or board, so that will need to be determined. Was/is there a ridge beam/board? It is not visible. Your photo is inconclusive for me here in GA.

Thank you so much for taking the time to respond to my post Robert, I do really appreciate it!
My pleasure.
Remember, I am not the only person chiming in. I am sure more images of the complete attic roof assembly will help.
You have no idea. And the added weight? How about fastener depth and integrity? Were the old slats attached to the new rafters?
A typical home inspector will not add anything more to the conversation. They will also recommend a SE.

Thanks Brian, will get one up here tonight.
There was a ridgeboard that was affected by the fire and is missing in parts.

Read what I said, home inspector / SE not what you infer.
Mommy, I am being picked on by Brian again.
I am not picking on you. I am attempting to help the OP. Feel free to support your statements. (such as locating a home inspector who is also a structural engineer. I guess anything is possible.)

Please try for a side view of the rafter structure, not a direct face shot of the sheathing.

An Inspector has already chimed in when the home was purchased.
At that time, it was likely perceived that the roofing system was stable. NOW, the roof will be worked on, and things will be changing, including a large amount of weight resting/moving upon the surface during reshingling activities.
While you could make a re-sheathed roof work, an Engineer is a must.
When you are tearing off that entire structure, and you will sooner or later, consider that you can improve the space. You can gain some head space, foam it in and get some very useful room. Do you get snow? I didn’t see, but by going with a 2x10 rafters with foam and batt, you can seal that space up tight, reduce your energy bills and have a very useful space. With all the burnt wood, I bet it still smells.

In my neck of the woods, very easy.
I am just going off what the OP posted.
1: Attic fire and repairs 50 years ago.
2: Our inspector (who I believe was an engineer) was not concerned about the integrity of the roof at the time - he called it surface charring and felt it was adequately supported.
3: 2 layers of shingles currently.
4: Roof requires recovering.
Did I miss anything?
