Shown below is an example of my exterior above my garage. I was wanting to look into painting/stucco/new siding work and wondered if what "bracing" you see as the same color of the house was purely decorative or if it applied to the structure of the house. To be more specific, these are the boards that run horizontal and vertical which are not white.
Some of the inside panels below/between these 1x6 boards may need to be replaced around the house and I wanted to assess replacement options/methods.
