Living with Timber

This post would have fit nicely into the "Before and After" thread... permies.com/t/258328
However, I neglected to take any before pictures so here we are in Timber framing!
This addition to our cabin was built in the early 1990s.  The young Douglas Fir tree was certainly not in our way, nor near the building...
In the years since I have watched this tree grow closer and closer...
By 2024 it had pushed the metal out of the way and was just touching the  2x4 eave board.  
A home-wrecking disaster in the making!
We do not get much wind in our valley but when we do that tree was pushing on the house!
Some folks might just cut down the offending tree... But not here... Here we move the offending section of the roof!
Our number 2 son was visiting so he got recruited for the project.
Temps were in the low 80s and humidity was 35% or so. (Hot for June in Montana)
Working on the north side in the shade made for a quick, easy job.
Well, easy for me as I was the ground guy and not allowed on the ladder... Geez one spill with a broken wrist and they never let you forget it!

I am in a similar position with a much smaller Maple tree. My concern is not the roof but the basement.

Sadly John, only one cure for that!
Build a new house!  
Or remove the offending tree...

if you put some drip edge along the opening you made it will help keep your 2x4"'s preserved from seasonal moisture.
I once did something very similar to my wood fence when I lived in the burbs and a big tree decided to branch out beyond the property line.
