This step by step woodworking project is about building a mini barn shed roof plans. This is the second article about how to build a mini gambrel shed, where I show you how to assemble the trusses and how to make the front door. My plans come with step by step instructions and you can easily adjust all the dimensions to suit your needs. See my other DIY projects HERE.
We recommend you to invest in the best materials you could afford. Therefore, you should buy weather-resistant lumber, such as pine or cedar. Always take accurate measurements before adjusting the size of the components at the proper size. Drill pilot holes trough the components before inserting the wood screws, to prevent the wood from splitting.

Building a mini barn roof
Build the rafters for the mini gambrel shed roof from 2×4 lumber. Cut both ends of the rafters at 67.5 degrees, as shown in the diagram. Smooth the edges with sandpaper for a neat result.
Lay the rafters on a level surface and then lock them together with 1/2″ plywood gussets. Mark the cut lines on the plywood sheet and then make the cuts with a circular saw.
Fit the trusses to the top of the shed frame, every 24″ on center. Use a spirit level to plumb the trusses and then secure them into place with screws. Drill pilot holes to prevent the wood from splitting.
Fit a 2×4 support to the front and back of the shed. Drill pocket holes at both ends of the supports and secure them into place with 2 1/2″ screws.
Fit the T1-11 siding sheets to the front face of the shed. As you can easily notice in the diagram, you need to mark the cut lines and get the job done with a saw. Cut out the door opening. Use 2″ brad nails to secure the sheets into place tightly.
Attach the T1-11 siding sheets to the back of the shed. Align the edges flush and then secure them into place with 2″ brad nails, every 8″ along the framing.
Assemble the overhangs for the barn shed from common rafters and 2×4 blockings. Drill pilot holes through the rafters and insert 3 1/2″ screws into the blockings. Leave no gaps between the components for a neat result.
Fit the overhangs to the front and back of the shed. Align the edges flush and then secure them into place with 3 1/2″ screws.
Attach the 3/4″ plywood sheets to the top of the barn shed, after cutting them to size. Align the edges flush and then secure them into place with 1 5/8″ screws.
Use 1×6 lumber for the trims. Make 22.5 degrees to both ends of the slats.
Attach the trims to the overhangs with 2″ brad nails. Leave no gaps between the components for a neat result.
You could fit asphalt shingles to protect the shed, as it is a straight forward solution. Therefore, install roofing felt over the roofing sheets, making sure the strips overlap at least 2″. Secure the tar paper to the plywood sheets with roofing staples. Fit the side drip edges over the roofing felt, while the bottom drip edges should be fit under. Place a starting course at the bottom of the roof, before installing the asphalt shingles. Always read the manufacturing instructions before starting the installation, as there are several aspects that differ.
Smart Tip: The first course should star with a 3 tab shingle, the second course with a 2 1/2 tab , the third course with a 2 tab, the forth course with a 1 1/2 tab, the fifth course with a 1 tab, the sixth course with a 1/2 tab. Repeat the process from the beginning, starting with the seventh course. Don’t forget that the shingles should overhang from the drip edge about a 1/4″. In addition, secure the asphalt shingles to the roof decking with tacks.
Fit 2×4 door jambs around the opening. Align the components with attention and then secure them into place with 2 1/2″ screws. Leave no gaps between the components for a professional result.
Frame the door from T1-11 siding. Use 2×4 lumber for the trims. Use glue and 2″ nails to secure the trims to the door panel.
Fit the door to the opening, as seen in the plans. Align the edges with attention and secure it to the jambs with hinges. In addition, you need to install a latch so you keep the door safely locked.
If you want to build the frame for this shed, make sure you take a look over PART 1. This shed is large enough for storing lots of items that any household inherently has. If you like my project, don’t forget to SHARE it on Facebook and Pinterest.
