This step by step diy project is about diy 12×16 lean to shed roof plans. This is PART 2 of the lean to shed project, where I show you how to build the lean to roof for the 12×16 shelter. Moreover, I have designed shed with many sizes so check them out, as well. Roof pitch is 2:12. 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. If you have all the materials and tools required for the project, you could get the job done in about a day.

Building a 12×16 lean to roof

Building-the-rafters
Build the rafters from 2×6 lumber. Mark the cut lines on the slats and get the job done with a circular saw.

Fitting-the-rafters—goat-shed
Fit the rafters to the top of the shelter and place them every 16″ on center. Use rafter ties and 1 1/2″ structural screws to lock the rafters to the top plates.

Fitting-the-rafter-blockings
Now we need to fit 2×6 blockings between the rafters to seal the gaps. Drill pocket holes at both ends of the blockings and then secure them to the rafters with 2 1/2″ screws.

Side-panels
Cut the panels for the side panels and secure them into place with 6-8d nails. Leave no gaps between the panels for a neat result.

Fitting-the-purlins
Fit the 2×4 purlins to the top of the lean to shed. See the side overhangs (12″). Place the purlins every 24″ on center and then secure them into place with 2 1/2″ screws.

Side-roof-trims
Fit the 1×6 trims to the sides of the shed. Align the edges flush and insert 2″ nails to lock them to the purlins.

Roof-trims
Fit the 1×6 trims to the front and back of the shelter. Align the edges flush, leave no gaps between the boards and then lock them into place with 2″ nails.

Fitting-the-roof-sheets
Fit the metal roofing sheets to the top of the shelter.

Door-frame
The next step of the project is to build the door frame. Cut the 2×4 components as shown in the diagram. Drill pocket hole at both ends of the vertical and middle components and then lock them together with 2 1/2″ screws. Align the edges flush and make sure the corners are square.

Attaching-the-door-panel
Attach the siding panel to the door frame. Align the edges flush and insert 2″ nails through the siding into the door frame. Align the edges flush and add glue to the joints.

Goat-door

Fitting-the-braces—goat-door
Now, we need to build the door for the goat area. Use 1×4 lumber for the components and cut them as shown in the diagram. Use a miter saw to make the angle cuts. Fit the components together tightly and insert 1 1/4″ screws to lock everything together tightly.

Fitting-the-door-jambs
Fit the 2×4 jambs around the door openings. Align the edges flush and insert 2 1/2″ screws to lock the jambs into place.

Fitting-the-shed-door
Fit the shed door to the opening and align the edges flush. Use 3 hinges and a latch to secure the door into place tightly.

Fitting-the-goat-door
Fit the door to the goat area. Set it to the jambs with hinges and install a latch.

Last but not least, you need to take care of the finishing touches.

Fill the holes with wood putty and let them dry out for a few hours. Smooth the surface with 100-220 grit sandpaper and remove the residues with a damp cloth.
Top Tip: Apply a few coats of paint or stain to the components, to enhance the look of the project. Check PART 1 of the project to learn how to build the frame of the shed.
