This step by step diy project is about 12×12 one horse barn roof plans. This is PART 2 of the project where I show you how to build the lean to roof with a 2:12 pitch. Make sure you check the local codes and make adjustments to the plans, if required. 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.

How to build a 12×12 barn shed roof
The first step of the project is to build the rafters for the roof of the barn shed. Use 2×8 lumber for the rafters. Mark the cut lines on the beams and then get the job done with a circular saw. Smooth the edges with sandpaper.
Fit the rafters to the top of the shed structure. Place the rafters every 16″ on center and lock them to the beams with rafter ties.
Fit the T1-11 siding sheets to the sides of the horse barn. Cut the sheets at the right dimensions and then lock them into place with 6-8d nails, every 8″ along the framing.
Assemble the side overhangs from 2×8 lumber. Drill pilot holes through the beams and insert 3 1/2″ screws into the supports. Place the supports equally spaced.
Fit the overhangs to the sides of the horse barn and align the edges with attention. Drill pilot holes and insert 3 1/2″ screws to lock the overhangs into place tightly.
Fit the 3/4″ plywood sheets to the top of the barn shed. Align the edges with attention and insert 1 5/8″ screws, every 8″ along the rafters.
Fit the 2×10 trims to the front and back of the roof. Use 3 1/2″ screws to lock the trims to the rafters.
Cover the roof with tar paper and then install the asphalt shingles. Make sure you also install the appropriate drip edges, so you can seal the shed roof. Read the manufacturer’s instructions for a tight fit.
I have lots of other shed projects on the site so I recommend you to browse through all alternatives before starting the building project. See all my shed projects HERE. Check out PART 1 and PART 3 of the shed project, so you learn how to build the frame of the shed and the dutch doors.
