This step by step diy project is about 6×8 gambrel shed roof plans. This is PART 2 of the storage barn shed project, where I show you everything you want to know about framing the barn shaped 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.

How to build a 6×8 barn shed roof
The first step of the project is to build the rafters from 2×4 lumber. Use a miter saw to make 22.5 degree cuts at both ends of the rafters.
Use a saw to make the birdmouths cuts to the base rafters.
Use 3/4″ 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 16″ on center and then plumb them vertically with a spirit level. Use rafter ties to secure the trusses into place tightly.
Fit the front wall frame to the shed. Align the edges flush, drill pilot holes and insert 3 1/2″ screws to lock everything tightly. Insert the screws into the adjacent walls and into the floor frame.
Fit the back wall to the shed, as shown in the diagram.
Use 2×4 lumber for the supports. Fit the supports to the back of the shed and use 2 1/2″ screws to lock them into place tightly.
Use T1-11 siding sheets for the front panels. Use a circular saw to make the cuts around the door opening. Fit the sheets to the and align the edges flush. Insert 6-8d nails every 8″ along the framing.
Cut the sheets for the back wall and attach them into place with 6-8d nails.
Use 3/4″ plywood for the roof. Fit the sheets to the roof of the shed and align the edges with attention. Insert 1 5/8″ screws every 8″ along the framing.
Fit the overhangs to the front and back of the barn shed. Align the edges with attention, drill pilot holes and insert 3 1/2″ screws to lock the overhangs to the shed frame.
Use 1×6 slats for the shed overhangs. Fit the slats to the roof of the shed and align the edges flush. Drill pilot holes and insert 1 5/8″ screws to secure the slats to the supports.
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.
Apply a few coats of paint over the exterior siding and trims to protect the components from the elements and to make the shed eye catching. Make sure you check out PART 1 and PART 3 of the project, so you see how to build the frame and the door for the gambrel shed.
