When to rip off old wood?

Hi everyone... I have a question regarding installing a new roof on my house.

Recently, I noticed a slight sag in one area of my roof. So - I got up in the attic to investigate. A truss broke, thus causing the sag at that location. Since my shingles look terrible (kinda discolored), I decided that I would re-shingle when I replaced the truss.

Everything else in the attic looks fine - even the truss that broke (old age maybe?) I have an older house, with what I would call "slats" for the roofing board. The wood looks great from inside the attic. No rotting, etc.

Basically, do I need to rip off this old wood and put new down? Or can I simply rip off the old shingles & paper? Is there something I should do or look for before deciding?

Thanks for any info!

If a rafter is broken, that will not get better with time.

Depending on the severity of the break and how much it has sagged, you may be able to jack it up with the existing roof deck planking remaining in place and sister in another rafter to it to straighten it out.

But, if it looks like that interior task would be too difficult, then the boards should be removed from the gutter eave edge all the way to the peak of thew roof and full length replacement would be your better choice.

Photos would help for more precise advice.

Thanks for the information. I assumed I would have to do some tearoff to replace it.

Sorry, I merged two questions into one! As for re-shingling my house.... should I do a tear-off the old wood? As I mentioned, from the attic, the wood looks like it's in good condition. It's old wood that *I believe* has natural discoloration (not the same smooth color as plywood). I actually believe the wood is Oak... it looks real similar to the oak trim throughout my house. I am going to walk the roof this weekend to feel for any soft spots. Is there anything else I can do to tell? I would love to replace only the shingles & paper. I've been told many times that I "might as well replace the whole roof while you're at it". This doesn't make much sense if the wood's in good shape.

I would suggest you to take the necessary action with the purview of long period. Rite now this can be at narrow stage but as the time will pass this gap will broad and broad. So keep such things in mind and than take care of such things.
