This step by step diy project is about 12×12 gable shed with porch roof plans. This gable shed roof has a 5:12 pitch and generous overhangs on all sides. Make sure you check the local building codes and make adjustments to comply with the local regulations. This shed roof is super easy to build, if you follow my diagrams with attention. 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, as it will pay off on the long run. Use a spirit level to plumb and align the components, before inserting the galvanized screws, otherwise the project won’t have a symmetrical look.

Building a 12×12 gable shed roof plans
The first step of the project is to build the trusses for the 12×12 shed with porch. As you can easily notice in the diagram, you need to build the rafters from 2×4 lumber. Cut the rafters at the right dimensions and angles using a saw. Lay the rafters on a level surface and align the edges with attention. Leave no gaps between the rafters.
Next, you need to build the supports that will reinforce the rigidity of the trusses. Fit 1/2″ plywood over the joints and align the edges. Insert 1 5/8″ screws to lock the gussets into place tightly.
Fit the trusses to the top of the shed. Plumb the trusses vertically and place the every 16″ on center. Use rafter ties to lock the trusses into place tightly.
Fit T1-11 siding panels to the gable ends. Mark the cut lines on the panels and then lock them into place with 6d nails. Leave no gaps between the panels.
Next, you need to assemble the overhangs for the shed. Drill pilot holes through the rafters and insert 2 1/2″ screws into the blockings.
Fit 3/4″ plywood sheets to the porch ceiling. Align the edges with attention and leave no gaps between the sheets. Insert 1 5/8″ screws, every 8″ along the trusses, for a professional bond.
Fit the overhangs to the front and back of the shed. Align the edges, drill pilot holes and insert 3 1/2″ screws to lock them into place tightly.
Cut the sheets for the roof from 3/4″ plywood and then fit them to the top of the shed. Align the edges with attention, drill pilot holes and insert 1 5/8″ screws, every 8″ along the rafters.
Fit the 1×6 trims to the sides of the roof. Align the trims with attention and insert 2″ nails.
Fit the 1×6 trims to the front and back of the roof. Align the edges and insert 2″ nails, every 8″ along the framing.
Cover the roof with tar paper and then install the asphalt shingles. Make sure you also install the appropriate drip edges, so you can seal the shed roof. Read the manufacturer’s instructions for a tight fit. Alternatively, you could also install metal sheets.
I have lots of other shed projects on the site so I recommend you to browse through all alternatives before starting the building project. See all my shed projects HERE. Moreover, check out PART 1 of the shed, so you learn how to build the frame of the shed. Check out PART 3 to learn how to build the double side doors, the front door and how to fit the decorative trims.
