This step by step diy project is about 12×12 gable shed roof plans. This is PART 3 of the garden shed project, where I show you how to build the gable roof and how to make sure it will be sturdy enough to withstand rains and moderate snows. You can easily adjust the slope of the roof to suit your needs. Take a look over the rest of my woodworking plans, if you want to get more building inspiration.
When buying the lumber, you should select the planks with great care, making sure they are straight and without any visible flaws (cracks, knots, twists, decay). Investing in cedar or other weather resistant lumber is a good idea. Use a spirit level to plumb and align the components, before inserting the galvanized screws, otherwise the project won’t have a symmetrical look. If you have all the materials and tools required for the project, you could get the job done in a few day. See all my Premium Plans HERE.

Building 12×12 gable shed roof
The first step is to build the rafters. Use a miter saw to make a 25.2 degree cut to one end of the rafters. In addition, make the birdsmouth cut to the rafters.
Cut the bottom rafters and then lay all the components on a level surface. Align the edges flush
Cut and fit the middle support to the trusses.
Use 1/2″ plywood for the trusses. Mark the cut lines on a piece of plywood and then get the job done with a saw. Lay the gussets over the joints and then insert 1 1/4″ screws to lock them into place tightly.
Fit the trusses to the top of the shed, every 16″ on center. Use rafter ties to secure the trusses into place. Plumb the trusses with a spirit level.
Cut and fit the T1-11 siding sheets to the front of the shed. Make sure you make the cuts around the double door opening.
Cut and fit the panels to the gable ends. Align the edges flush and make sure there are no gaps between the panels. Use 8d nails to secure the panels to the framing, every 8″.
Assemble the overhangs, as shown in the diagram. Drill pilot holes through the rafters and insert 3 1/2″ screws into the blockings.
Fit the overhangs to the front and back of the storage shed. Align the edges flush, drill pilot holes and insert 3 1/2″ screws to lock them into place tightly.
Use a circular saw to make the cuts to the plywood sheets. Fit the 1/2″ plywood sheets to the roof of the 12×12 shed. Align the edges flush and insert 1 5/8″ screws, every 8″ along the rafters. Leave no gaps between the sheets.
Use 1×6 lumber for the gable roof trims. Use a miter saw to make a 25.2 degree cut to one end of the slats. Use 2″ nails to secure the trims into place tightly, after you align the edges flush.
Fit the 1×6 trims to the sides of the shed roof. Align the edges and insert 2″ nails to secure them into place tightly.
Build the porch railings from 2×4 lumber and 2×2 lumber. Place the balusters equally spaced. Drill pilot holes through the cleats and insert 2 1/2″ screws into the balusters.
This storage shed is compact enough to save space in your backyard, while offering tons of storage space.
Last but not least, you need take care of the finishing touches. Fill the holes with wood putty and then smooth the surface with 120-220 grit sandpaper. Apply a few coats of paint or stain to the components, so you can protect them from decay and so you can enhance the look of the shelter. Check out PART 1 and PART 3 of the shed, so you can learn everything you need to know about building the floor, walls and roof for the shed.
