12×16 Run In Shed Roof Plans

This step by step diy woodworking project is about 12×16 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. The roof has a 2:12 roof pitch. Take a look over PART 1 of the plans to see how to build the frame of the shed. Make sure you check out the rest of woodworking 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 12×16 lean to shed roof

Back wall panels

Use T1-11 siding sheets for back walls. Secure the panels into place with 6d nails, every 8″ along the framing

Rafters-for-12×16-loafing-shed

Build the rafters from 2×8 lumber. Make notches to the rafters, using the information from the diagram. Smooth the recesses with sandpaper.

Fitting-the-rafters

Fit the rafters to the top of the compact run in shed. Drill pilot holes and lock the rafters to the structure with screws and rafter ties. Place the rafters every 16″ on center.

Side lean to supports

Use 2×4 lumber for the side lean to supports. Drill pocket holes at both ends of the supports and secure them into place with 2 1/2″ screws.

Fitting-the-side-wall-panels

Use T1-11 siding sheets for the side walls. Secure the panels into place with 6d nails, every 8″ along the framing. Leave no gaps between the panels and make the cuts along the framing.

Front wall panels

Attach T1-11 siding to the front of the shed. Make cuts to the panels. Use 6d brad nails to lock the sheets into place tightly. Insert the nails every 8″ along the wall framing.

Fitting the purlins

Fitting-the-roof-purlins

Use 2×4 lumber for the roof purlins. Center the purlins to the roof of the shed and secure them to the rafters with 2 1/2″ screws. Place the purlins every 16″ on center.

Side roof trims

Fit 1×6 trims to the sides of the lean to roof. Use 2″ nails to secure the trims into place tightly.

Front and back roof trims

Attach 1×10 trims to the front and back of the roof.

Fitting the metal roof sheets

Cover the roof of the shed with metal sheets. Start from the bottom up to the top.

Last but not least, you need to take care of the finishing touches. Fill the holes with wood putty and smooth the surface with 120-220 grit sandpaper. Apply a few coats of paint or stain to trims and to the exterior of the walls.
