I was going to use a different word than "stuff" but this is a family friendly blog.
I participated in the making of the thing in the picture above. The shed is pre-existing, but the new section of roof is intended to improve the outdoor cooking experience of certain people. The structural characteristics of this roof are somewhat dubious, but consistent with other things built nearby. I can't predict its longevity, but I'm confident that it will last as long as it should.
