It pays to engineer

As I drove to drop Delaney off this morning at the bus, I saw this:

This is my neighbor’s leanto, just off the road as I leave the property. Apparently it didn’t survive the wind all that well. Part of his roof was ripped off:

 

I didn’t see this one being built, but I looked at it closely to check out the construction. Seemed flimsy to me. Not a lot of cross bracing, and the roof was 2 4x4s, butt jointed with the posts and screwed in. Not much support there.

And apparently not enough screws.
