This step by step diy project is about 10×16 gambrel shed roof plans. This is PART 2 of the storage shed project, where I show you everything you want to know about framing the gambrel roof. From building the rafters to fitting the roof itself, I’ve got you covered with instructions and diagrams. 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 gambrel shed roof
The first step of the project is to build the trusses for the 10×12 barn shed. As you can easily notice in the diagram, you need to cut the rafters from 2×4 lumber. Make 22.5 degrees to both ends of the rafters and then lay them on a level surface.
Use 1/2″ plywood for the gussets. Mark the cut lines on the plywood sheet and get the job done with a saw. Fit the gussets over the joints and then lock them to the joints with 1 5/8″ screws.
Fit the trusses to the top of the barn shed. Fit the trusses every 24″ on center and then plumb them vertically with a spirit level. Use rafter ties to secure the trusses into place tightly.
Use 2×4 lumber for the gambrel ends of the barn shed. Cut the top of the supports at 77.5 degrees and drill pocket holes at both ends. Fit the supports into place and insert 2 1/2″ screws to lock them tightly.
Cut the sheets for the gambrel ends and then lock them to the supports with 6-8d nails, every 8″. Leave no gaps between the sheets for a professional result.
Use 3/4″ plywood for the roof of the barn. Cut all the sheets to the right dimensions and then attach them to the roof of the barn shed. Use 1 5/8″ screws to secure the panels into place, every 8″ along the rafters.
Fit the 2×4 trims to the front and back of the barn shed, as shown in the plans. Align the edges flush, leave no gaps between the components and insert 2″ nails to secure them into place tightly.
If you want to protect the front and the back of the shed from rain/snow, you can attach overhangs easily. Check out the rest of my barn shed projects to see how to frame a super simple overhang.
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.
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.
