8×16 Gambrel Shed Roof – Free DIY Plans

This step by step woodworking project is about 8×16 gambrel shed roof plans. This is the PART 2 of the 8×16 garden shed project, where I show you how to build the gambrel roof for the shed. Building the roof for the shed is really easy if you follow my tips and diagrams with attention. Read the local codes before starting the project, so you comply with the requirements. 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.

8×16 Gambrel Shed Roof – DIY Plans

Rafters

Rafters

Use 2×4 lumber for the rafters. Mark the cut lines on the beams and then get the job done with a circular saw. Smooth the edges with sandpaper.

Fitting the gussets

Fitting the gussets

Use 1/2″ plywood for the gussets. Use a circular saw to make the cuts, as shown in the diagram. Add the gussets to the rafters and lock them into place with 1 5/8″ screws.

Fitting the trusses

Fitting the trusses

Fit the rafters to the top of the shed. Place the rafters every 16″ on center, equally spaced, as shown in the diagram. Drill pilot holes and insert 3 1/2″ screws to lock the rafters into place tightly. Alternatively, you can use rafter ties to lock the trusses to the plates.

Assembling the front wall

Assembling the front wall

Use 2×4 lumber for the front wall frame. Use a miter saw to make the angle cuts and then secure them into place tightly. Take accurate measurements and drill pilot holes before inserting the screws, to prevent the wood from splitting.

Back wall gambrel supports

Back wall gambrel supports

Use 2×4 lumber for the gambrel end supports. Drill pocket holes at both ends of the supports and then insert 2 1/2″ screws to lock them into place tightly.

Fitting the side wall panels

Fitting the side wall panels

Use T1-11 siding sheets for the side wall panels. Mark the cut lines on the sheets and then get the job done with a saw. Align the edges with attention and insert 6-8d nails, every 8″ along the framing.

Front wall panels

Front wall panels

Fit the panels to the front and back walls. As you can see in the diagram, you need to make a few cuts to fit the panels around the door opening.

Building the overhangs

Building the overhangs

Use 2×4 lumber for the overhangs. You can adjust the size of the overhangs according to the size of the blockings.

Fitting the overhangs

Fitting the overhangs

Fit the overhangs to the front and back of the shed. Align the edges with attention, drill pilot holes and insert 3 1/2″ screws.

Fitting the roof sheets

Fitting the roof sheets

Fit 3/4″ plywood sheets to the roof of the shed. Align the sheets with attention, making sure you leave no gaps between them. Insert 1 5/8″ screws to lock the sheets into place, every 8″ along the rafters.

Roof trims

Roof trims

Use 1×6 lumber for the front and back roof trims. Cut the trims as shown in the diagram. Attach the trims to the gable ends and then lock them into place with 2 1/2″ screws.

Fitting the roofing

Fitting the roofing

Cover the roofing sheets with tar paper. Install the tar paper starting with the bottom of the roof and make sure the strips overlap for at least 2″. In addition, fit a 12” strip over the top ridge. Install the shingles starting with the left- bottom of the roof, after fitting the starting course. Use roofing tacks to secure the shingles into place.
