Anyone here a building contractor (or know one?)
 

First things first. The house I'm living in was built in the 1940's-50's and had an addition put on in the 90's. They left the old roof in place when they put the addition on and just cut a hole in the old roof for access into the addition's attic. I'm doing some work in the attic and I'm getting tired of crawling through that hole. Given the pictures below, do you see any reason why I can't cut more out so I can basically just walk into the addition's attic? Only support I see is a couple pieces of hardwood flooring supporting the section I'd want to cut out.

Anyone anything?

The part with the 2x4 does no longer seem to be supporting anything, bu I am not sure what ties the old roof has to each side.

You need a header across where that 2x is cut off. Make it two pieces thick and screw them together and into the bottom cord of each truss.
