Hot take: A level floor matters more than a square roof on a small shed build
I was about to start my roof sheathing last Saturday when my neighbor Bill walked over and said 'don't bother squaring that up until your floor is dead level.' I had been fighting with a 1.5 inch slope on my 8x10 shed slab for two days trying to shim everything. He told me to just pour a thin self leveling patch first and let it cure overnight. Sure enough after that the walls went up straight and the roof came together in about 3 hours with zero gaps. Has anyone else found that fixing the base first saved them tons of headache later on a DIY project?
My first shed had a 2 inch low corner I tried to fix with shims, ended up with a roof that looked like a funhouse mirror. Leveling the slab first would have saved me three weekends of cursing and a trip to the chiropractor. Did you have to redo any framing after realizing how much the floor mattered?
Started leveling the ground way better the second time around, literally just spent a whole afternoon with a long level and a gravel rake before I even poured the slab. Made a world of difference, no weird roof lines or crooked walls.
