I like to use the hip roof design, it is pleasing to the eye, it is the best roof for high winds, certainlly a good idea with the hurricanes and tropical storms found in South Florida. I always build my sheds on a raised concrete slab for stability, I also use double hurricane ties. All studs and rafters are pressure treated because of the area's termite problems. I always anchor the shed to the concrete slab with expoy bolts. I never use T11 siding it does not hold up well in a subtropical climate. I use OSB under the siding and I often cross brace. I prefer a metal roof screwed down not nailed using water gasket screws. I generally use ridge vents or a wind turbine to help cool the shed and I also use Bahama shutters for the same reason. I build with rafters not trusses so I can keep the celling open to also cool the shed. This makes the shed expensive but after twenty years of use one of my oldest sheds which received proper up keep is still perfect. So which is cheaper one shed for life or one after every major windstorm? I know the answer because I had one shed stand up to a huricane!
Don’t be tempted to get sloppy when you square up the floor and walls of your shed. An out-of-square start will haunt you through the rest of the project, from doors and windows to trim and roofing. For a concrete slab, measure diagonally across the opposite corners of the form boards. Then adjust the forms until the diagonal measurements are equal. Do the same for a wood platform floor. If you’re installing sheet siding on the walls, before you stand them up, measure diagonally and square up the wall before you nail on the siding.
Build the framework for all four walls. To account for the fact that the front and back walls are different from each other (due to the doorframe in the front) and the side walls must both be sloped (to prevent rain from collecting on the roof), each of these will have to be tackled somewhat differently. It’s easiest to construct the back first, the front second, and the two sides last, as shown in the numbered image below. See How to Frame a Wall for more information before you read the instructions below.[5]
