8×12 Gable Shed Roof Plans

This step by step woodworking project is about 8×12 gable shed roof plans plans. This is the PART 2 of the 8×12 garden shed project, where I show you how to build the gable roof. You can easily adjust the slope of the roof to suit your needs. 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. See all my Premium Plans in the Shop.

How to build a gable roof for a 8×12 shed

Building the rafters

Use 2×4 lumber for the rafters. Mark the cut lines on the slats and then get the job done with a saw. Make 25 degree cuts to both ends of the rafters, using a miter saw. Set the miter saw at 25 degrees.

Assembling the trusses

Lay the rafters on a level surface and build the bottom rafter from 2×4 lumber. Cut both ends of the bottom rafters at 25 degrees. (set the miter saw at 65 degrees) Align the edges with attention, making sure you leave no gaps between the components.

Fitting the gussets

Use 1/2″ plywood for the gussets. Mark the cut lines on the plywood sheet and then get the job done with a circular saw. Lay the gussets over the joints and use 1 5/8″ screws to secure the gussets into place.

Fitting the trusses

Fit the trusses to the top of the shed. Place the trusses every 24″ on center and use a spirit level to plumb them. Use rafter ties to lock the rafters to the shed frame.

Gable end supports

Use 2×4 lumber to build the supports for the front and back gable ends. Mark the cut lines on the slats and get the job done with a saw. Drill pocket holes at both ends of the supports and lock them into place with 2 1/2″ screws.

Building the gable end panels

Use T1-11 siding for the gable ends. Mark the cut lines on the siding sheets and get the job done with a saw. Fit the panels to the gable ends and lock them into place with 6-8d nails, every 8″ along the framing.

Assembling the overhangs

Build overhangs for the front and back of the 8×12 shed. Use rafters and 2×4 blockings to assemble the front and back overhangs. Drill pilot holes through the rafters and insert 3 1/2″ screws into the blockings.

Fitting the overhangs

Fit the overhangs to the front and back gable ends. Align the edges flush, drill pilot holes through the overhangs and insert 3 1/2″ screws into the roof frame.

Fitting the roof sheets

Fit the 3/4″ plywood sheets to the roof of the garden shed. Cut the panels to the right dimensions and then attach them to the frame of the shed. Drill pilot holes and insert 1 5/8″ screws, every 8″ along the rafters. Leave no gaps between the sheets for a professional result.

Fitting the roofing

You could fit asphalt shingles to protect the shed, as it is a straight forward solution. Therefore, install roofing felt over the roofing sheets, making sure the strips overlap at least 2″. Secure the tar paper to the plywood sheets with roofing staples. Fit the side drip edges over the roofing felt, while the bottom drip edges should be fit under. Place a starting course at the bottom of the roof, before installing the asphalt shingles. Always read the manufacturing instructions before starting the installation, as there are several aspects that differ.

Smart Tip: The first course should star with a 3 tab shingle, the second course with a  2 1/2 tab , the third course with a 2 tab, the forth course with a 1 1/2 tab, the fifth course with a 1 tab, the sixth course with a 1/2 tab. Repeat the process from the beginning, starting with the seventh course. Don’t forget that the shingles should overhang from the drip edge about a 1/4″. In addition, secure the asphalt shingles to the roof decking with tacks.
