This step by step diy project is about 8×8 lean to shed roof plans. This is PART 2 of the free 8×8 gambrel shed plans, where I show you how to build the roof. If you need even more storage space, you can create a small loft. Make sure you check the local codes and make adjustments to the plans, if required. 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. See all my Premium Plans HERE.

Building a 8×8 gambrel shed roof
The first step of the project is to build the rafters for the gambrel shed. Use a miter saw to make 22.5 degrees cuts to both ends.
Lay the rafters on a level surface and leave no gaps between them. Use 1/2″ plywood for the gussets and use the information from the diagram to get the job done. Use 1 5/8″ screws to lock the gussets over the rafters.
Fit the trusses to the top of the shed and place the every 16″ on center. Plumb the trusses with a spirit level and use rafter ties to lock them into place tightly.
Fit 2×4 supports to the front and back gambrel ends of the shed. Use the diagram to make the cuts to the supports, drill pocket holes at both ends and insert 2 1/2″ screws to lock them into place tightly.
Use T1-11 siding for the panels. Use a saw to cut the panels at the right size and dimensions and then align the edges flush. Insert 6-8d nails, every 8″ along the framing.
Fit the overhangs to the front and to the back of the shed. Align the edges with attention, drill pilot holes and insert 2 1/2″ screws to lock them into place tightly.
Cut the roof sheets at the right dimensions and then fit them to the top of the shed. Align the edges with attention and insert the 1 5/8″ screws, every 8″ along the framing.
Fit the 1×6 trims to the front and to the back of the shed roof. Cut both ends of the trims at 67.5 degrees (set the miter saw at 22.5 degrees). Use 2″ nails to lock the trims into place tightly. Leave no gaps between the trims for a professional result.
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.
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.
