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 shed. Moreover, I have designed shed with many sizes so check them out, as well. Roof pitch is 4:12. 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. See all my Premium Plans HERE.

Building a 12×16 lean to roof
Fit the 5/8″ T1-11 siding sheets to the back of the shed. Align the edges flush, make cuts, and secure the panels to the frame, every 8″, using 6-8d nails.
Attach the panels to the front of the shed, as well. Align the edges flush and cut out the opening using a circular saw.
Build the rafters from 2x8lumber. Mark the cut lines on the slats and get the job done with a circular saw.
Fit the rafters to the top of the lean to shed. Place the rafters every 16″ on center and lock them into place with rafter ties and 1 1/2″ structural screws.
Fit 2×4 supports to the lean to ends of the shed. Drill pilot holes at both ends of the supports and insert 2 1/2″ screws to lock them into place tightly.
Cut the panels for the lean to ends and secure them into place with 6-8d nails. Leave no gaps between the panels for a neat result.
Assemble the side overhangs from 2×8 lumber. Drill pilot holes through the sides and insert 3 1/2″ screws into the blockings.
Fit the blockings to the sides of the shed, align the edges flush and secure them into place with 3 1/2″ screws.
Lay the 3/4″ plywood sheets to the top of the shed starting with the bottom of the roof. Use 1 5/8″ screws to secure the sheets into place, every 8″ along the rafters.
Fit the 1×10 trims to the sides of the shed. Align the edges flush, leave no gaps between the boards and then lock them into place with 2″ nails.
Fit the 1×10 trims to the front of the shed. Align the edges flush, leave no gaps between the boards and then lock them into place with 2″ nails.
Cover the roof of the shed with roofing felt, making sure the strips overlap at least 2″. Secure the tar paper to the plywood sheets with roofing staples. In addition, cut a 12″ piece for the top ridge. Fit the side drip edges over the roofing felt, while the bottom drip edges should be fit under.
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 and PART 3 to learn how to build the door for the shed.
