12×16 Garden Shed Roof Plans

This step by step woodworking project is about 12×16 gable shed roof plans plans. This is the PART 2 of the 12×16 garden shed project, where I show you how to build the gable roof for the shed. The gable roof has a 22.5 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. See all my Premium Plans HERE.

How to build a 12×16 gable shed roof

Building a trusses

The first step of the project is to build the trusses for the shed. Use 2×4 lumber for the rafters and make the angle cuts as shown in the diagram. Lay the components on a level surface, such as the shed frame and make a jig, so you can assemble all the trusses easier. Leave no gaps between the rafters and then align the edges flush.

For the rafters set the miter saw at 22.5 degrees (after the cut, the rafter angle will be 67.5 degrees).

For the bottom chord, set the miter at 67.5 degrees (after the cuts, the angles will be 22.5 degrees).

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 then lock them into place with 1 5/8″ screws.

Fitting the trusses

Fit the trusses to the top of the shed, every 16″ on center. Use a spirit level to plumb the trusses and then secure them into place with rafter ties.

Gable end supports

Fit the 2×4 supports to the gable ends of the shed. Make a 22.5 degree cut to one end of the supports, as shown in the diagram. Make the angle cuts to the supports, drill pocket holes at both ends and then secure them into place tightly with 2 1/2″ screws.

Gable end panels

Attach T1-11 siding to the gable ends, as shown in the diagram. Use a circular saw to make the cuts to the sheets and then secure them into place with 6-8d nails, along the framing.

Assembling the overhangs

Build the overhangs for the shed from rafters and 2×4 blocking. Remember that you can easily adjust the size of the overhangs to suit your needs. Drill pilot holes through the rafters and insert 2 1/2″ screws.

Fitting the overhangs

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

Shed roof sheets

The next step of the project is to attach the 3/4″ plywood sheets to the top of the shed. Align the edges flush and secure them into place with 1 5/8″ screws, every 8″ along the framing. Make sure you leave no gaps between the sheets for a neat result.

Side roof trims

Fit the 1×6 trims to the sides of the roof. Cut the trims at the right dimensions and then secure them into place tightly with 2″ nails.

Front and back trims

Build the front and the back roof trims from 1×6 lumber. Make the angle cuts to the trims and then secure them into place with 2″ nails.

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. Attach the asphalt shingles to the roof, making sure you follow the manufacturer’s instructions.
