A wood post that seems to be holding up the roof over my porch is rotting at the bottom. Upon closer inspection, I have realized it is made of four 1×5’s nailed into a square and the center is empty. I would expect maybe a decorative post to be made this way but it looks like it’s necessary to support the roof.
My neighbor has a similar porch design and his posts are made the same way, which makes me think it’s original to the house. Has my roof been supported by some flimsy 1×5’s for 55 years? Do I need to worry about my roof sagging until this is fixed?
