This step by step diy woodworking project is about 12×12 run in shed roof plans. This article is PART 2 of the run in shed project, where I show you how to frame the lean to roof and how to fit the decorative trims. Make sure you check out the rest of plans to see alternatives and more projects for your garden.
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 12×12 shed roof plans
Build the rafters from 2×8 lumber. Make notches to the rafters, using the information from the diagram. Smooth the recesses with sandpaper.
Fit the rafters to the top of the shelter. Drill pilot holes and lock the rafters to the structure with screws and rafter ties. Place the rafters every 16″ on center.
Use 2×4 lumber for the side lean to roof supports. Make the angle cuts with a miter saw and then lock them into place tightly with screws.
Attach T1-11 siding to the back wall of the shelter. Use 6d brad nails to lock the sheets into place tightly. Insert the nails every 8″ along the wall framing.
Cut the 3/4″ plywood sheets at the right dimensions, as shown in the diagram. Align the edged with attention and leave no gaps between the sheets. Insert 1 5/8″ screws, every 8″ along the framing.
Fit the 2×10 trims to the sides, to the front and to the back of the shed. Cut the components at the right dimensions and then align them into place with attention. Drill pilot holes and then insert 3 1/2″ nails, every 8″ along the framing.
Attach 1×10 trims to the front and back of the roof. Use 3 1/2″ screws to secure the trims into place tightly.
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 100-200 grit sandpaper and remove the residues with a damp cloth.
