This step by step diy project is about 12×12 saltbox shed roof plans. This is PART 2 of the garden storage shed project, where I show you how to build the saltbox shaped roof. This small shed is easy to build and it has an unique and distinctive design. 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.

How to build a 12×12 Saltbox Shed Roof
Build the rafters for the shed from 2×6 lumber. As you can easily notice in the diagram, you need to make an angle cut to one end of the rafters and then cut out the birdsmouth. Take accurate measurements so you get a consistent result.
Use 2×4 lumber for the bottom rafters. Use a miter saw to make the angle cuts at both ends of the rafters. Fit the bottom rafter on a level surface, as shown in the diagram.
Use 1/2″ plywood for the gussets. Cut the gussets at the right shape and size, as shown in the diagram, and then fit them over the joints, as shown in the plans. Drill pilot holes and insert 1 5/8″ screws to lock everything together tightly.
Fit the trusses to the top of the 12×12 shed frame. Place the trusses every 16″ on center. Use a spirit level to plumb the trusses and fit rafter ties to secure them to the top plates. The rafter ties will lock the trusses into place tightly.
Use T1-11 siding for the side wall panels. Cut the panels to the right size and shape and then secure them into place with 6-8d nails. Align the edges flush and insert the nails every 8″.
Cut the roof sheets from 3/4″ plywood. Align the edges flush and then insert 1 5/8″ screws, every 8″ along the rafters, so you lock them into place tightly. Alight the edges flush and leave no gaps between the sheets, for a professional result.
Fit the 3/4″ plywood sheets to the other side of the roof. Use the information in the diagram to get a professional result.
Use 1×8 lumber for the side roof trims. Use 2″ brad nails to secure the trims into place tightly.
Fit the 1×8 trims to the front and back of the roof. Align the edges flush and insert 2″ nails, so you secure the trims into place tightly. The trims are easy to install and it will add unique appeal to the shed.
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.
