12×8 Gable Shed Roof Plans

This step by step woodworking project is about 12×8 shed roof plans plans. This is the PART 2 of the 12×8 garden shed project, where I show you how to build the gable roof for the shed. The gable roof has a 30 degree slope and it will add unique charm to the shed. My plans come with step by step instructions and you can easily adjust all the dimensions to suit your needs. 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.

Building a 12×8 gable shed

Building the trusses

Building the trusses

First of all, you need to build the trusses for the 12×8 gable shed. Cut the bottom rafter and the regular rafters from 2×4 lumber. Use a miter saw for accurate repetitive cuts. Lay the rafters on a level surface and leave no gaps between the components. Use 2×4 lumber for the supports. Leave no gaps between then components and then reinforce the joints with metal plates or with 1/2″ plywood gussets.

Fitting the trusses

Fitting the trusses

After you assemble the trusses you need to fit them on the top of the shed. Fit the trusses every 24″ on center. Plumb the trusses with a spirit level and then lock them into place with rafter ties.

Fitting the roof sheets

Fitting the roof sheets

Fit 3/4″ plywood sheets to the top of the shed roof. Align the edges with attention and then secure them along the rafter with 1 5/8″ screws, every 8″. Make sure you leave no gaps between the sheets for a professional result.

Side roof trims

Side roof trims

Fit 1×6 trims to the sides of the shed. Align the trims with attention and then insert 2″ nails so you can lock them into place tightly.

Front and back roof trims

Front and back roof trims

Use 2×6 lumber for the front and back overhangs of the roof. Align the overhangs with attention and insert 2 1/2″ screws to lock the components into place tightly. Leave no gaps between the components for a professional result.

Fitting the roofing

Fitting the roofing

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. Make sure you cover the top ridge with a 12” strip of roofing felt. The front and back drip edges should be fitted under the felt, while the sides over.

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.
