This step by step diy woodworking project is about 12×16 barn shed roof plans. The project features instructions for building a gambrel roof for a 12×16 barn shed. This barn comes with supports for a basic loft, so all you are left to do is attach the loft floor. Check out PART 3 of the article to see how to frame the double shed doors. See the rest of plans for more outdoor projects.
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. Read the local building codes before starting the project, as you might need a building permit. In addition, level the area and remove the vegetation layer.

Building a gambrel roof
The first step of the project is to build the rafters for the barn shed. Cut both ends of the rafters at 67.5 degrees. Take accurate measurements and get the job done with a miter saw.
Build the gussets for the trusses from 3/4″ plywood. Mark the cut lines on the plywood and get the job done with a circular saw. Attach the gussets to the rafters and lock them into place with 1 5/8″ screws.
Fit the trusses to the top of the barn shed, making sure they are placed equally-spaced. Plumb the trusses with a spirit level, drill pilot holes and insert 3 1/2″ screws into the plates.
Build the loft supports from 2×4 lumber. Cut both ends of the beams at 67.5 degrees.
Fit the supports to the top plates and secure them to the trusses, as shown in the diagram. Drill pilot holes at both ends of the supports and insert 2 1/2″ screws into the trusses.
Build the gambrel ends support from 2×4 lumber. Make the angle cuts to the top of the supports, as shown in the plans.
Fit the supports to the front and back faces of the shed, as shown in the plans. Toe-nail the supports to the frame of the shed.
Build the gambrel ends from T1-11 siding. Cut the sheets at the right shape and dimensions. Attach the sheets to the frame and lock them into place with 1 5/8″ nails, every 8″ along the framing.
Build the overhangs for the barn shed. Adjust the width of the overhangs to suit your needs. Drill pilot holes through the rafters and insert 2 1/2″ screws into the blocking.
Fit the overhangs to the front and to the back of the shed. Align the edges with attention, drill pilot holes and insert 3″ screws into the rafters.
Attach 3/4″ plywood sheets to the rafters, using the pattern shown in the diagram. Drill pilot holes and insert 1 5/8″ screws, every 8″ along the rafters. Leave no gaps between the tongue and groove sheets.
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.
Make sure you take a look over the PART 3 of the project, to learn how to build the double doors.
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.
