This step by step woodworking project is about 4×12 gable shed roof plans. This is the PART 2 of the 4×12 garden shed project, where I show you how to build the gable roof for the shed. Building the roof for the shed is really easy if you follow my tips and diagrams with attention. Read the local codes before starting the project, so you comply with the requirements. See my other DIY projects HERE.
We recommend you to invest in the best materials you could afford. Therefore, you should buy weather-resistant lumber, such as pine or cedar. Always take accurate measurements before adjusting the size of the components at the proper size. Drill pilot holes trough the components before inserting the wood screws, to prevent the wood from splitting.

4×12 Gable Shed Roof Plans
Use 2×4 lumber for the rafters. Mark the cut lines on the beams and then get the job done with a circular saw. Smooth the edges with sandpaper.
Fit the rafters to the top of the shed. Place the rafters every 24″ on center, equally spaced, as shown in the diagram. Drill pilot holes and insert 3 1/2″ screws to lock the rafters into place tightly.
Use T1-11 siding sheets for the gable ends. Mark the cut lines on the sheets and then get the job done with a saw. Align the edges with attention and insert 6-8d nails, every 8″ along the framing.
Build overhangs for the shed from 2×4 lumber. You can adjust the size of overhangs to suit your needs. Drill pilot holes through the rafters and insert 2 1/2″ screws into the blocking.
Fit the overhangs to the front and to the back of the shed. Align the edges with attention, drill pilot holes and insert 2 1/2″ screws to lock them into place tightly.
Fit 3/4″ plywood sheets to the roof of the shed. Align the sheets with attention, making sure you leave no gaps between them. Insert 1 5/8″ screws to lock the sheets into place, every 8″ along the rafters.
Use 2×6 lumber for the front and back roof trims. Cut the trims as shown in the diagram. Attach the trims to the gable ends and then lock them into place with 2 1/2″ screws.
Fit 1×6 trims to the sides of the roof. Align the edges with attention and then insert 2″ nails to lock them into place tightly.
Cover the roofing sheets with tar paper. Install the tar paper starting with the bottom of the roof and make sure the strips overlap for at least 2″. In addition, fit a 12” strip over the top ridge. Install the shingles starting with the left- bottom of the roof, after fitting the starting course. Use roofing tacks to secure the shingles into place.
This shed is narrow and it is ideal if you need storage space but you have a narrow backyard.
