10×10 Barn Shed Roof with Loft Plans

This step by step diy woodworking project is about 10x10 barn shed  roof plans. This is PART 2 of the barn shed project, where I show you free plans and step by step plans diagrams for building the roof and the loft. Remember that you need to read the local building codes before starting the construction, so you comply with the legal requirements. See my other shed plans 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 10×10 gambrel roof

Rafters

Rafters

The first step of the project is to build the rafters for the shed roof. Cut both ends of the 2×4 beams at 67.5  degrees.

Gussets

Gussets

Lay the rafters on a level surface and then attach 1/2″ plywood gussets. Insert 1 1/4″ screws to lock the gussets to the joints. Align the edges flush for a professional result.

Fitting the trusses

Fitting the trusses

After assembling the trusses, you need to fit them to the top of the storage shed. Place the trusses every 16″ on center and then plumb them with a spirit level. Use rafter ties to lock the trusses into place tightly.

Fitting the gambrel end supports

Fitting the gambrel end supports

Fit 2×4 supports to the gambrel ends. Drill pocket holes at both ends of the supports and then secure them into place with 2 1/2″ screws.

Gambrel end panels

Gambrel end panels

Cut the panels for the gambrel ends from T1-11 siding. Mark the cut lines on the panels and then get the job done with a saw. Smooth the edges flush and then insert 6-8d nails, every 8″ along the framing. Leave no gaps between the sheets for a professional result.

Loft joists

Loft joists

Fit the 2×6 joists to the back of the shed, as shown in the diagram. Drill pilot holes through the beams and insert 2 1/2″ screws to lock them into place tightly. Cut both ends of the beams at 67.5 degrees (make 22.5 degree cuts).

Loft floor

Loft floor

Fit 3/4″ plywood sheets to the joists to create the loft, for even more storage space. Align the sheets with attention and insert 1 5/8″ screws, every 8″ along the joists.

Building the overhangs

Building the overhangs

Building the overhnags for the front and back of the barn shed is easy. Use rafters and 2×4 blockings to assemble the overhangs. You need to adjust the size of the overhangs to suit your needs.

Front and back overhangs

Front and back overhangs

Fit the overhangs to the front and to the back of the shed. Align the edges flush and then drill pilot holes. Insert 2 1/2″ screws to lock the overhangs into place tightly.

Fitting the roof sheets

Fitting the roof sheets

Cut the sheets for the roof from 3/4″ plywood. Fit the sheets to the top of the shed and then align the edges flush. Leave no gaps between the sheets and insert 1 5/8″ screws, every 8″ along the rafters.

Fitting the roof trims

Fitting the roof trims

Use 1×6 lumber for the front and back roof trims. Cut the trims at the right size and angle and then lock them into place tightly with 2″ nails. Leave no gaps between the trims for a professional result.

Fitting the roofing

Fitting the roofing

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.

The loft makes this small barn shed feel special and really useful. This 10×10 shed is compact but also roomy enough for the needs of a modern family. If you like my project, don’t forget to SHARE it on Facebook and Pinterest.
