Guys, I am getting ready to put some flooring down in my attic to make more room for storage. I have three cross members (?) in my attic that I was unsure about. I have included a few pictures below. They are located in my town house which was a gable roof. The cross members are about 8in tall but only a 1/2 in thick. They don't seem very sturdy so I cant imagine they are structural. I wanted to see if anyone could identify them and see if I am able to safely remove them. Thanks guys.
