4×12 Lean to Shed Roof Plans

This step by step woodworking project is about free 4×12 lean to shed roof plans. This is PART 2 of the small storage lean to shed project where I show you how to frame the roof. The lean to roof is the ideal choice if you want to build it near the property line. Moreover, the 32″ wide front door will help you have an easy access inside the shed with large objects. 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.

Step 5: Building the lean to shed roof

Fitting-the-back-wall-siding-sheets

Attach the T1-11 siding sheets to the back wall of the shed. Align the edges flush and leave no gaps between them. Insert 6d nails every 8″ along the framing, to secure the panels into place.

Rafters-for-the-4×12-shed

Next, build the rafters for the lean to roof using 2×4 lumber. Mark the cut lines on the slats and get the job done with a circular saw. The birdsmouth cuts are needed so you can fit the rafters into place tightly. You have everything you need to make the cuts, in the diagram.

Fitting-the-rafters

Next, fit the rafters every 16″ on center and align the edges with attention. Use rafter ties and 1 1/2″ structural screws to lock the rafters into place tightly.

Step 6: Attaching the siding sheets

Front-wall-panels—lean-to-shed

Also, attach the T1-11 siding sheets to the front of the shed. Make the cuts to the sheets and then align them into place. Use 6-8d nails, every 8″ along the framing. Nevertheless, you need to make the cuts around the door opening so you can fit the door. Use a circular saw to get the job done.

Side-panels-for-the-4×12-lean-to-shed

Last but not least, attach the panels to the sides of the shed.

Step 7: Fitting the roofing

Overhangs

Building the overhangs for the small garden shed is a straight forward job. Drill pilot holes through 2×4 beams and insert 2 1/2″ screws into the blockings.

Fitting-the-side-overhangs

Attach the overhangs to the sides of the backyard shed, align the edges flush and insert 3 1/2″ screws to lock them into place tightly.

Roof sheets

The next step of the woodworking project is to attach the 3/4″ plywood sheets to the top of the shed. Cut the sheet as noted in the diagram, align the edges flush and insert 1 5/8″ screws to secure them to the rafters.

Fitting-the-shed-roof-sheets

Fit the 1×6 trims to the front and back of the lean to roof. Align the edges flush and insert 2″ nails to lock them into place tightly.

Fitting-the-side-roof-trims

Fit the 1×6 trims to the sides of the shed, as well.

Fitting-the-shed-roofing

Cover the roof with tar paper and staple it into place. Next, attach the asphalt shingles, starting with the bottom left side of the shed. Insert the nails and read the manufacturer’s instructions, so you can cover the roof properly.

Step 8: Finishing touches

Last but not least, you need to take care of the finishing touches. Therefore, fill the holes with wood putty and then smooth the surface with sandpaper. Apply a few coats of paint or stain over the components to enhance the look of the shed and to protect the components from decay.

I have designed this small 4×12 lean to shed so you can store all your garden tools and organize the rest of your items (sports equipment and so on). Check out PART 1 of the project for free shed frame plans. See all my SHED PLANS, as well, as I have lots of designs that come in many sizes. You can see in the diagram the overall dimensions of the shed, so you can decide if this is what you are looking for.
