This step by step diy woodworking project is about how to build a 8×8 shed roof plans. The project features instructions for building a gable roof for a 8×8 storage shed. This shed also features a small loft for storing miscellaneous items. Work with attention and make adjustments to the design and overall dimensions if you want to get the job done in a professional manner. check out the first part of the project to learn how to build the frame of the 8×8 shed.
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.

8×8 Shed Roof Plans
The first step of the project is to build the rafters for the shed. As you can easily notice in the diagram, you need to cut both ends of the 2×4 rafters at 60 degrees. Take accurate measurements and use a miter saw for making accurate angle cuts.
Next, you need to make a notch to the rafters, as shown in the diagram. Use a circular saw to make the notch and smooth the edges with sandpaper.
Attach the bottom rafter to assemble the trusses. Make cuts to the upper corners of the 2×4 beam. Drill pilot holes and insert 2 1/2″ screws to lock everything tightly. In addition, install 3/4″ plywood gussets to secure the top rafters together tightly. Use 1 1/4″ screws to lock the gusset to the rafters.
Fit the trusses to the top of the shed, making sure you place the equally-spaced. Plumb the trusses with a spirit level and secure them to the top plates using 2 1/2″ screws. Drill pilot holes and toenail the bottom rafters to the top plates, as shown in the diagram.
If you want to enhance the storage space of the 8×8 shed, we recommend you to create a basic loft. Attach the 3/4″ plywood sheets to the bottom rafters and secure them into place with 1 1/4″ galvanized screws.
Next, you need to attach the gable ends to the front and back faces of the shed. Cut the sheets at the right dimensions using a good circular saw. Align the panels to the structure of the shed and secure them into place with 1 1/4″ finishing nails.
Continue the project by assembling the overhangs for the shed. First of all, you need to build the rafters for the overhangs out of 2×4 lumber. Cut both ends of the components at 60″ and smooth the cut edges with sandpaper.
Next, assemble the overhangs by fitting the 4″ long blockings. You can make the blocking longer or shorter according to your needs and tastes. Use 2 1/2″ screws to lock the blockings to the rafters. In addition, drill pilot holes through the top of the rafters and secure them together with 2 1/2″ screws.
After assembling the overhangs, you need to attach them to the front and back of the shed. Align the overhangs with attention, drill pilot holes and insert 2 1/2″ screws into the structure of the shed.
Next, you need to attach the 3/4″ plywood sheets to the rafters, as shown in the plans. Cut the panels at the right dimensions and secure them with 1 1/4″ screws, every 8″ along the rafters. Leave no gaps between the sheets and use tongue and groove plywood as much as possible.
In order to enhance the look of the shed, you need to attach 1×6 trims cover the end rafters. Use a saw to make the cuts to the 1×6 slats. Cut both ends of the trims at 60 degrees and smooth the edges with fine-grit sandpaper.
Fit the trims to the ends rafters and secure them into place with 1 1/4″ finishing nails. In addition, attach 1×6 trims to the sides of the shed to cover the ends of the regular rafters. Align the trims with attention and secure them into place with 1 1/4″ brad nails.
Cover the roof with tar paper, making sure the strips overlap at least 2″. Then install the asphalt shingles starting with the bottom of the roof. Read here more about how to install the asphalt shingles.
This step is optional so you can skip it if it doesn’t add value to your project. You can install a 2×2 door stop to the double header, as shown in the diagram. Use 2 1/2″ screws to secure the door stop to the structure, after pre-drilling pilot holes.
Building the door for the shed is a straight forward step. Use the panel cut out for the door opening and 1×4 lumber to build the doors. Use 1 1/4″ brad nails and glue to lock the trims to the door panel. However, you might need to sand the edges of the door a little if it fits too tightly into place. In this case, use a planer to take out about 1/8″ on each edge of the door.
Fit 1×4 trims around the door opening to create the jambs. Use 1 1/4″ finishing nails to secure the trims into place. Fit the door to the opening and secure it to the jambs with hinges. In addition, attach a shed door latch to lock it properly.

Fill the holes and dents with wood putty and let it dry out for several hours. Use 120-200 grit sandpaper to smooth the surface. You can also attach 1/4″ plywood soffit to enhance the look of the shed. Make sure you check out the first part of the project to lean more how to build the 8×8 shed.
Top Tip: If you want to enhance the look of the project and to protect the wood storage shed, we recommend you to cover the components with paint or stain.
