This step by step diy project is about 12×8 shed roof plans. This is PART 2 of the storage shed project, where I show you how to build the gable roof. I show you step by step with diagrams and instructions, everything you need to know about building the gable roof. Take a look over the rest of my woodworking plans, if you want to get more building inspiration. Remember that you need to select the site for the shed with attention and that you have to comply with a few legal regulations.
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. If you have all the materials and tools required for the project, you could get the job done in about a day. See all my Premium Plans HERE.

12×8 Shed Roof Plans
Start the woodworking project by assembling the trusses for the shed. As you can easily notice in the diagram, you need to cut the rafters from 2×4 lumber. Cut both ends of the rafters at the right angle and then lay them on a level surface. Align the edges with attention and leave no gaps between the components.
Use 1/2″ plywood for the gussets. Mark the cut lines on the sheet and then get the job done with a circular saw. Fit the gussets over the joints, align the edges with attention and insert 1 5/8″ screws.
Fit the trusses to the top of the shed. Place the trusses every 24″ on center, as shown in the diagram. Use a spirit level to plumb the trusses and then lock them into place with rafter ties. If you want to seal the shed, you could fit 1×4 blockings to the sides of the shed, between the trusses. Drill pocket holes at both ends of the blockings and insert 1 1/4″ screws to lock them into place tightly.
Use 2×4 lumber for the gable end supports. Cut the supports at the right size and angled and then drill pocket holes at both ends. Secure the supports into place with 2 1/2″ screws.
Cut the panels for the gable ends from T1-11 siding. Attach the panels to the front and back of the shed. Align the edges flush and insert 6-8d nails every 8″ along the framing.
Fit the 3/4″ plywood to the roof of the shed. Align the edges with attention and then insert the 1 5/8″screws, every 8″ along the rafters.
Fit 2×6 overhangs to the front and to the back of the shed. Align the edges with attention and then drill pilot holes. Insert 2 1/2′ screws to secure the beams into place tightly.
Fit the 1×6 trims to the sides of the roof. Align the edges and insert 2″ brad nails so you can lock the trims to the end of the rafters.
Cover the roof of the shed with roofing felt, making sure the strips overlap at least 2″. Secure the tar paper to the plywood sheets with roofing staples. In addition, cut a large piece for the top ridge. Fit the side drip edges over the roofing felt, while the bottom drip edges should be fit under.
Read the instructions labeled on the asphalt shingle packs before installing them into place tightly. Start with the bottom left side of the roof and install them all the way to the top.
In PART 3 of the project I show you how to attach the 1×4 trims to the exterior of the shed, besides framing the front double doors.
You need to check out PART 3 of the shed, so you learn how to build the double doors and how to fit the rest of the trims. If you have’t looked over PART 1 yet, I recommend you to do it, as it will show everything you want to know about building the frame of the shed.
