This step by step woodworking project is about building a 14×16 barn shed roof plans. This is PART 2 of the barn shed project, where I show you how to build the gambrel roof and how to attach the roofing. Check out PART 3 of the project for the double door plans. 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.

How to build a 14×16 gambrel roof
The first step of the project is to build the trusses for the barn shed. Cut the rafters from 2×6 lumber, by making 22.5 degree cuts to both ends. Lay the four rafters on a level surface.
Build the gussets for the trusses from 3/4″ plywood. Mark the cut lines on the plywood sheets and then get the job done with a circular saw. Smooth the edges with sandpaper and then lay the gussets to the joints. Align the edges flush, drill pilot holes and insert 1 5/8″ screws.
Fit the trusses to the top of the shed. Place the trusses every 24 on center and use a spirit level to plumb them vertically. Use rafter ties to lock the trusses to the top plates.
Use 24 lumber for the gambrel end supports. Make a 22.5 degree cut to the top of the supports and then drill pocket holes at both ends. Fit the supports into place and insert 2 1/2″ screws to lock them into place tightly. Make sure the edges are flush and check if the corners are right angled.
Use T1-11 siding for the gable end panels. Cut the sheets at the right size and shape and then lock them into place with 6d nails, every 8″ along the framing.
Fit the 3/4″ plywood to the roof of the barn shed, as shown in the diagram. Cut the panels to the right size and then secure them to the roof framing with 1 5/8″ screws. Drill pilot holes before inserting the screws, to prevent the wood from splitting.
Use 2×6 rafters and blockings to assemble the overhangs for the shed. Drill pilot holes through the rafters and insert 3 1/2″ screws into the blockings.
Fit the overhangs to the front and to the back of the barn shed and align the edges flush. Drill pilot holes and insert 3 1/2″ screws to secure them into place tightly.
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.
Fill the holes with wood putty and then smooth the surface with 120-220 grit sandpaper. Apply a few coats of paint or stain over the trims and components to enhance their look and to protect them from decay.
If you want to build the frame for this shed, make sure you take a look over PART 1. Check out PART 3 for the instructions on how to build the double doors. 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.
