This step by step project is about 4×8 shed roof plans. After building the frame of the small garden shed, we recommend you to continue the backyard project by attaching the rafter, the overhangs, the roofing sheets and the front door to the structure. You could adjust the length of the rafters and of the overhangs, to suit your needs and your budget. Don’t forget to check out the rest of the shed projects featured on our site, if you want to consider other shapes or shed designs.
There are several aspects that any person should take into account before starting the woodworking project. First of all, you need to use weather-resistant lumber, such as cedar, pine or redwood. Drill pocket holes at both ends of the components, if you want to lock them together tightly. In addition, add wood glue to the joints and check if the corners are right-angled. Plan everything from the very beginning, if you want to get a professional result.

Building a shed roof
The first step of the woodworking project is to build the rafters for the 4×8 shed. As you can notice in the diagram, we recommend you to cut one end of the rafters at 60 degrees, by using a miter saw.
Smooth the cut edges and make the notches at the bottom of the rafters, to fit around into place. Take accurate measurements and make the cuts with a circular saw.
Next, you need to fit the top ridge to the small garden shed. Cut the supports out of 2×4 lumber and the top ridge out of 2×6 lumber. Drill pocket holes at both ends of the supports and fit them to the middle of the top plates. Insert 2 1/2″ screws to secure the supports into place.
Secure the top ridge to the supports by insert 2 1/2″ screws. Make sure the corners are right-angled before inserting the screws. Plumb the supports with a spirit level.
Next, fit the 2×4 rafters to the top ridge and to the top plates. In order to get the job done in a professional manner, we recommend you to place the rafters equally-spaced. Drill pilot holes at both ends of the rafters and insert 2 1/2″ screws into the plates and into the top ridge.
Work with attention and use a spirit level to make sure the top ridge is horizontal, before fitting the rafters on both sides.
In order to increase the durability of the 4×8 shed and to enhance its appearance, we recommend you to build overhangs for both the front and the back of the garden shed. Cut the rafters out of 2×4 lumber, as well as the blockings. Drill pilot holes through the rafters and insert 2 1/2″ galvanized screws into the blockings.
Make sure all the joints are rigid and leave no gaps between the components. Repeat the process for the opposite overhang.
Next, you need to attach 5/8″ T1-11 siding to the gable ends of the 4×8 shed. Mark the cut lines on the plywood siding and get the job done with a circular saw. Smooth the edges with sandpaper and secure the sheets to the structure using 1 1/4″ galvanized screws.
Align the overhangs to the gable ends making sure the edges are flush. Drill pilot holes through the overhangs and insert 3 1/2″ screws into the roof rafters. Make sure there are no gaps between the components and align everything with great care.
Attach the 1×4 trims to the end of the rafters before fitting the roofing sheets and the drip edges. Align the trims with attention and secure them to the rafters by using 2″ finishing nails.
The next step of the woodworking project is to attach the 3/4″ plywood sheets to the rafters. In order to get the job done in a professional manner, we recommend you to adjust the dimensions of the plywood sheet to the right size and to center them to the sides of the roof.
Secure the sheets to the rafters by using 2″ nails, every 8″. Work with attention and leave no gaps between the components, if you want to get a professional result.
Afterwards, we recommend you to attach the 3/4″ plywood sheets to the overhangs of the shed roof, as described in the diagram. Smooth the edges and make sure they are flush with the trims. Leave no gaps between the sheets and insert 2″ into the overhangs, every 8″
Make sure there are no gaps between the sheets and the rafters before inserting the screws into place.
In order to get the job done in a professional manner, we recommend you to cover the roofing sheets with tar paper. Install the tar paper starting with the bottom of the roof and make sure the strips overlap for at least 2″. In addition, fit a 12” strip over the top ridge.
Install the shingles starting with the left- bottom of the roof, after fitting the starting course. See more about fitting the shingles here. Use roofing tacks to secure the shingles into place.
Building the garden sheds door is a straight forward process. Build the frame out of 1×4 lumber, following the instructions in the diagram. Make sure you secure the frame components together, by using pocket holes and screws.
Use the piece of siding that you have cut it out in the previous steps. Make sure the edges are flush and insert 1 1/4″ nails through the frame into the panel. Add glue to the joints.
Build the door jambs out of 1×4 lumber, making sure you adjust their dimensions to the right size. Align the door jambs to the opening, making sure the edges are flush one with another. Secure the doors to the components by inserting 2″ finishing nails into the studs.
Attach the hinges to the door and fit it inside the opening. Insert screws through the hinges in the jambs and fit a door latch.
Last but not least, you should take care of the finishing touches. Therefore, fill the holes with wood putty and let the compound to dry out for several hours. Smooth the surface with medium-grit sandpaper along the wood grain.
Top Tip: Apply several coats of paint to enhance the look of the 4×8 shed and to protect the components from decay. Check out the rest of the projects to see how to build the frame of the shed.
