10x20 Gable Shed Roof Plans | HowToSpecialist - How to Build, Step by Step DIY Plans

This step by step woodworking project is about free 10×20 gable shed roof plans. This is PART 2 of the large shed project, where I show you how to build the gable shaped roof and how to make the double doors. Check out the rest of the projects for detailed instructions on how to make the frame for the shed. Read the local codes and make sure you comply with the regulations. See my other DIY projects HERE.

We recommend you to invest in the best materials you could afford. Therefore, you should buy weather-resistant lumber, such as pine or cedar. Always take accurate measurements before adjusting the size of the components at the proper size. Drill pilot holes trough the components before inserting the wood screws, to prevent the wood from splitting. See all my Premium Plans HERE.

Building a gable roof for a 12×20 shed

Rafters – 10×20 gable shed

The first step of the project is to build the rafters for the 10×20 gable shed roof. Use a miter saw to make the angle cuts to the rafters, as shown in the diagram.

Fitting the gussets

Lay the rafters on a level surface and then leave no gaps between them. Use 1/2″ plywood for the gussets. Attach the gussets to the joints. Drill pilot holes and insert 1 5/8″ screws to lock the gussets into place tightly. Add glue to the joints.

Fitting the trusses

Fit the trusses to the top of the 10×20 shed. Place the trusses every 16″ on center and use a spirit level to plumb them. Use rafter ties to secure the rafters into place tightly.

Gable roof panels

Use T1-11 siding for the gable ends. Cut the panels at the right dimensions and shapes and then lock them into place with 6-8d nails.

Roof sheets

The next step of the project is to attach the 1/2″ plywood sheets to the top of the roof. Align the edges flush and then lock them to the rafters, every 8″, using 1 5/8″ screws. Make sure you leave no gaps between the sheets for a nest result. You can use other patterns for laying the sheets, as well.

Front and back roof trims

Use 2×6 lumber for the front and back roof trims. Make 26.6 degree cuts to both ends of the trims and then attach them into place with 2 1/2″ screws.

Side roof trims

Fit the 1×6 trims to the sides of the roof. Use 8d nails to lock the trims into place tightly.

Roofing – 10×20 gable shed

The next step of the woodworking project is to cover the roof with felt. As you can see in the image, you need to make sure the strips of roofing felt overlap at least 2”. In addition, you have to lock the tar paper to the plywood sheets with staples. Next, you should install the shingles to the roof of the large shed. Start with the bottom of the roof, by fitting the first course, as in the image. Use roofing tacks to secure the shingles to the roofing sheets.

Start the first course with a full tab, the second with 2 1/2 tabs, the third with 2 tabs, the forth with 1 1/2 tabs, the fifth with 1 tab, the sixth with half tab and the seventh with a 3 tabs. Secure the shingles with roofing tacks.

Jambs for double doors

Use 2×4 lumber for the door jambs. Attach the trims around the opening and align the edges flush. Insert 2 1/2″ screws to lock the jambs into place tightly.

Double doors

Build the double doors from T1-11 siding and from 2×4 lumber. First, you need to assemble the door frame using pocket holes and 2 1/2″ screws. Make sure the corners are square and align the edges with attention. Fit the panels to the door frames and secure them into place with 2″ brad nails.

Fitting the double doors

Fit the doors to the opening and secure them to the jambs with hinges. Install a door latch so you can keep the shed locked up and your belongings safe.

Side door jambs

Fit the 2×4 jambs around the side door.

Side door

Assemble the side door for the shed in the same manner described above.

Fitting the side door

Fit the door to the side of the shed. Align the edges and use hinges and a latch to lock the door into place tightly.

Side trims

Fit the 1×4 trims to the sides of the shed. Align the edges flush. Insert 8d nails to lock the trims to the walls.

Corner trims – 10×20 Shed Plans

Use 1×4 lumber for the front and back trims. Align the trims with attention and insert 8d nails to lock them into place tightly.

Fitting the trims around the windows

You can also add 1×4 trims around the windows.
