TL;DR: want to install a pergola structure over my window, need to remove one row of siding. not sure how to proceed.
My house has a concrete foundation, then bricks up to what looks like the second level, then Aluminum siding. I want to install a pergola structure over my bay window. The brick runs up both sides of the window. The siding covers the top of the window. It is not clear to me if the brick runs across the top of the window frame or not.
So, my question: what is most likely under that siding? OSB? If I remove the row of siding and there is OSB underneath what I could I do to cover it properly? Add more Brick? Brick facade? I wouldn't want to put siding between the house and the pergola. And obviously, if it's just more brick then I'd do nothing.
Thanks in advance.
