I’m re-siding a 40 year old house with 3/4 inch shiplap sheathing-probably fir or hemlock. After removing the old builders felt and while marking stud locations in prep for stapling up new felt, I found one small area of rot — about a half inch wide by a quarter inch deep and 5 inches long running with the grain. I scraped it out with the back end of my pencil and moved on.
But now I’m wondering if I should remove the felt, scrape with a steel tool and saturate with wood preserative. If I did so so, I would need to snap new chalk lines to replace lines that are already on the new builders felt, so it’s much more than a 10 minute job.
From the position and morphology of the streak of rot and my knowledge of the history of the house, I suspect this board may have had the rot since the house was built. And it should stay completely dry.
Would you treat the rot? This is my house.

you could have a knothole that big...
Don't worry, If you install the new work right, it will not get wet again so the rot cannot get worse than it is.

You can tell it's gonna bother him though.....for a while.
If having a low wage work force was good for a country's economy then why hasn't Mexico built a fence?
Its a lot easier to take care of it now than later.
He took care of it

I've got bigger things to let bother me than a small amount of rot. :-)
But I've heard conflicting things about it. Common wisdom is that if you can keep the wood dry, there'll be no more problems. This location will be easy to keep bone dry.
More recently, I've heard that you have to kill all the microorganisms to stop the rot. I'm a little confused about what happens to rot that you leave in place but keep dry. Does it keep growing? If dry, does it go dorment and cause no more problems?
it is just like you - a living organism. It needs food - the wood - water, and air to grow. Deny it any of the three and it remains dormant

OK. Thanks. I'll keep moving on.
