10×20 Lean to Shed Roof Plans

This step by step woodworking project is about 10×20 lean to shed roof plans. This is the PART 2 of the large storage shed, where I show you how to build the lean to roof. This shed features front and back overhangs. You can also easily add side overhangs to the roof of the shed, if you want. You can adjust the slope of the roof, to suit your local building codes. 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.

10×20 Lean to Shed Roof – DIY Plans

Building the rafters – 10×20 shed

Use 2×6 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 rafters – 10×20 shed

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.

Side panels – 10×20 shed

Use T1-11 siding sheets for sides of the shed. Use 8d nails to secure the sheets to the wall frames, every 8″ along the framing.

Fitting the roof sheets – 10×20 shed

Fit 1/2″ 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.

Side roof trims – 10×20 storage shed

Use 1×8 lumber for the side roof trims. Use 8d nails to secure the trims into place.

Fitting the front trims – 10×20 shed

Fit the trims to the front and back of the shed roof.

Fitting the roofing – 10×20 lean to shed

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″. 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.

Double doors – 10×20 shed

Use 2×4 lumber for the door frame. Assemble the door frame with 2 1/2″ pocket screws and then attach the T1-11 siding panel with glue and nails.

Door jambs – 10×20 shed

Attach the 2×4 jambs around the door opening. Align the edges flush and insert 2 1/2″ screws to secure the jambs into place tightly.

Fitting the double doors

Fit the door to the opening and align the edges flush. Use hinges to attach the door to the jambs. Install a latch.

10×20 Lean to Shed Plans

This shed is ideal if you want a no frills project that is based more on the essentials and less on the design features. This shed is built on a sturdy 2×4 framing with 2×6 rafters. Make sure you take a look over PART 1 of the project, so you learn how to build the frame for the shed. I also have plans for a 10×20 gable shed, so don’t miss them out if you are still doubting if the lean to roof is the best choice for your needs. You should also check my 12×16 lean to shed plans.
