12×16 Gable Shed Roof Plans

This step by step woodworking project is about free shed roof plans. This article is PART 2 of the shed with garage door project, where I show you how to build the gable roof. 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.

Building a gable roof for a 12×16 ATV shed

Building-the-rafters

The first step of the woodworking project is to build the rafter for the shed. Cut both ends of the rafters at 65 degrees. In addition, you need to make a birdsmouth cut to the rafters, so they fit easily to the frame of the shed. Use 2×6 lumber for the rafters.

Fitting-the-bottom-rafter

Use 2×4 lumber for the bottom rafters, cutting their both ends at 25 degrees. Lay the rafters on a level surface. Leave no gaps between the components.

Trusses-supports

You need to attach 2×4 supports to the trusses placed at both ends of the structure, so you can attach the gable end panels.

Attaching-the-gussets

Attach the 1/2″ plywood gussets to the joints, so you reinforce the rigidity of the structure.

Fitting-the-trusses-and-the-blockings

Fit the trusses to the top of the storage shed, every 24″ on center. Use a spirit level to plumb the trusses and lock them into place with rafter ties. In addition, you can install the 1×4 blocking between the trusses so you seal the shed. Drill pocket holes at both ends of the blockings and insert 2 1/2″ screws to lock them into place tightly.

Fitting-the-gable-ends

Attach the T1-11 siding panels to the gable ends of the shed. Use 2″ brad nails to secure the panels into place tightly.

Overhang-rafters

The next step of the project is to build the overhangs for the shed. Use 2×6 lumber for the rafters. Cut both ends of the rafters at 65 degrees using a miter saw.

Assembling-the-overhangs

Assemble the overhangs using the rafters and the 2×6 blockings. Drill pilot holes through rafters and insert 2 1/2″ screws into the blockings. Leave no gaps between the components for a neat result.

Fitting-the-overhangs

Attach the overhangs to the front and back of the shed. Align the edges flush, drill pilot holes and insert 3 1/2″ screws to lock them into place tightly.

Fitting-the-roofing-sheets

Attach 3/4″ plywood sheets to the roof of the shed. Align the sheets with attention and secure them into place with 1 5/8″ screws, every 8″ along the rafters.

Fitting-the-side-roof-trims

Fit the 1×6 trims to the sides of the shed. Use 2″ nails to lock the trims into place tightly.

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.
