This step by step diy project is about 4×16 lean to shed roof plans. This is PART 2 of the free 4×16 shed plans, where I show you how to build the lean to roof and the front double 4′ doors. In addition, I show you how to add decorative trims to the shed. The pitch of the roof is 6/12. Make sure you check the local codes and make adjustments to the plans, if required. Take a look over the rest of my woodworking plans, if you want to get more building inspiration.
When buying the lumber, you should select the planks with great care, making sure they are straight and without any visible flaws (cracks, knots, twists, decay). Investing in cedar or other weather resistant lumber is a good idea, as it will pay off on the long run. Use a spirit level to plumb and align the components, before inserting the galvanized screws, otherwise the project won’t have a symmetrical look. See all my Premium Plans HERE.

Building a 4×16 lean to shed roof

Building-the-rafters
First of all, you need to build the rafters for the lean to shed. Mark the cut lines on the 2×4 boards and then get the job done with a circular saw. Smooth the edges with sandpaper.

Fitting the rafters
Fit the rafters to the top of the shed, every 16″ on center. Align the edges with attention and use rafter ties to lock them into place tightly.

Lean to panels
Fit the panels to the lean to ends. Align the edges and insert 2″ nails, every 8″ along the framing.

Fitting the roof sheets
Fit the 3/4″ plywood sheets to the top of the shed. Align the sheets with attention and leave no gaps between them. Insert 1 5/8″ screws, every 8″ along the framing.

Roof trims
Fit 2×6 trims to the sides of the roof and 1×6 trims to the front and back. Use 2 1/2″ screws to lock the trims into place tightly.

Fitting the roofing
Cover the roof with tar paper and then install the asphalt shingles. Make sure you also install the appropriate drip edges, so you can seal the shed roof. Read the manufacturer’s instructions for a tight fit.

Fitting the door jambs
Fit 1×4 jambs around the opening. Align the edges with attention and insert 2″ nails, every 8″ along the framing.

Building-the-doors
Build the door panel from T1-11 siding and the trims from 1×4 lumber. Use 1 1/4″ screws to lock the panels to the trims. Add glue to the joints and align the edges flush.

Fitting the doors
Fit the doors to the openings and align the edges with attention. Use hinges to lock the doors to the jambs. Install a latch to lock the doors tightly.

Back wall trims
Fit 1×4 trims to the back of the shed. Align the edges with attention and insert 2″ nails, every 8″ along the framing, so you can secure them into place tightly.

Side wall trims
Fit the 1×4 trims to the sides of the shed, as well.

Front wall trims
Last but not least, fit the 1×4 trims to the front of the shed. Align the edges with attention and insert 2″ nails to lock them into place tightly.

As you can see in the diagrams, this narrow shed comes with a lot of storage space so you can get the job done super easily. The two pair of doors make it ideal for an easy access. You can add a partition to the shed, as well.
