Question 2x8 Running Adjacent To Chimney Rotted Out

Happy New Year.

I realized last week cleaning out my attic that about a 10' section of the second beam from the edge of my roof due to water that must have been coming in from the flashing around chimney over the last 12 years the house has been built (from where it buts against the chimney of my oil furnace all the way to the end where it hits the guter... about 10').

The roof material itself has no black rot on it. I fixed the flashing but i'm asking what would be the most economical way to fix this problem permanently for me. Looking for advice.

Is it possibly to strip it out from isnide the attic with a sawzall and put in a replacement section ?

How would a roofer do this for a customer on a budget ?

This is not really a roof problem, however you culd ask them. This should be repaired from the inside, not the outside. It is a pretty simple job for any good carpenter. He will probably sister in another 2x10 or whatever size it needs to be. Don/t cut a hole in a perfectly good roof. Good Luck.

Smile Thanks

Thank you for your reply. Sounds like a job i can do which makes me even happier

Is there any risk that the rotten 2x10 wood rot will travel to the new sister beam added ? I don't know anything about rotten wood... don't know if it travels and needs to be cut out.

Once the moisture is removed the rot stops. I would still remove as much of the rotted wood as possible, since if it is soft all the way through it is not bearing any load anyway and it can still attract other pests. Once the wood is heavily rotted it can also act as a sponge and conceal any future leaksby absorbing the water. this would allow the rot spores to become active and attack any nearby wood that is damp. Like the new piece sistered against the rotted piece.

look into repointing the flashing on your chimney
