16×16 Lean to Shed Roof Plans

This step by step woodworking project is about free 16×16 lean to shed roof plans. This is PART 2 of the large storage lean to shed project where I show you how to frame the roof and how to build the front door and the side double doors. 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

Building-the-rafters

Firstly, build the rafters for the lean to roof using 2×6 or 2×8 lumber (read the local codes for best choice). 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.

Side-lean-to-roof-supports

Use 2×4 lumber for the side lean to supports. Ma the cuts to the top of the supports, drill pocket holes at both ends and insert 2 1/2″ screws to lock them into place tightly.

Step 6: Attaching the siding sheets

Back-wall-siding-sheets

Use T1-11 siding for the back of the shed. Make the cuts to the sheets and then align them into place. Use 6-8d nails, every 8″ along the framing. Also, I recommend you to leave no gaps between the panels.

Fitting-the-siding-sheets-to-the-front-wall

Attach the siding sheets to the opposite wall of the shed. Leave no gaps between the sheets and use the same procedure shown above. In addition, use a circular saw to make the cuts around the openings.

Siding-sheets-for-the-shed-side-walls

Fit the T1-11 siding panels to the sides of the storage shed. On the opposite side of the garden shed use a saw to make the cuts around the double door opening.

Step 7: Fitting the roofing

Fitting-the-purlins

I recommend you to use 1×4 lumber for the purlins. Set the boards to the top of the shed, as shown in the diagram. Use 2 1/2″ screws to lock the purlins to the rafters. You can adjust the size of the side overhangs to suit your needs.

Fitting-the-roof-trims

In addition, you can add 1×8 boards to the front and back of the roof, to hide the ends of the rafters. Use 6d nails or screws to lock these trims to the rafters,

Fitting-the-roof-sheets

I have designed this shed with metal sheets roofing. Therefore, you need to set the metal sheets to the roof structure and lock them to the purlins with the appropriate screws.

Step 8: Building the front shed door

Fitting-the-shed-windows

Fit the PVC shed windows into place and then attach the 1×4 decorative ends to enhance the look of the project.

Front-wall-door-jambs

Fit 2×4 jambs around the door opening. Align the boards with attention and then lock them into place tightly with 2 1/2″ screws.

Assembling-the-shed-door-frame

Next, build the door frame for the shed. Cut all components for the frame from 2×4 lumber. Drill pocket holes at both ends of the vertical and middle boards. Lay the slats on a level surface, align the edges flush and make sure the corners are square. Insert 2 1/2″ screws to assemble the door frame together tightly.

Assembling the door for shed

Continue the project by attaching the T1-11 siding that you have cut out in the previous steps and lay them over the door frames. Use 1 5/8″ screws to secure the panels to the frames tightly. Make sure the edges are flush.

Fitting-the-front-door

Fit the door to the front of the garden shed. Align the edges with attention and lock them to the jambs with hinges. Attach a latch to lock the doors together tightly.

Double-door-jambs

Next, attach the 2×4 jambs around the double door opening. Align the edges flush and insert 2 1/2″ screws to lock them into place tightly.

Building-the-double-door-frames

Assemble the double door frames in the same manner described above. Align the edges flush and make sure the corners are square.

Attaching-the-door-panel

Continue the project by attaching the siding panel to the door frame.

Fitting-the-double-doors-to-the large–shed

Last but not least, you need to attach the double doors to the side of the storage shed. Use hinges and a latch to set the doors into place.

Step 9: Finishing touches

Also, 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.
