8×12 Lean To Shed Roof Plans

This step by step woodworking project is about 8×12 lean to shed roof plans. This is the PART 2 of the 8×12 lean to shed project, where I sow you how to build the roof and how to attach the siding to the rest of the walls. 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. See all my Premium Plans in the Shop.

How to build a lean to shed roof

Building the rafters

The first step of the project is to build the rafters from 2×4 lumber. Mark the cut lines on the 2×4 beams and then get the job done with a circular saw. Smooth the edges with sandpaper.

Fitting the rafters

Fit the rafters to the top of the shed and place them every 24″ on center. Use rafter ties to lock the rafters to the top plates.

To back wall – Siding

Use T1-11 siding for the top side of the back wall. Mark the cut lines on the siding and get the job done with a jigsaw. Smooth the edges with sandpaper. Fit the siding panels to the back of the wall and lock them into place with 6-8d nails. Leave no gaps between the panels for a professional result.

Side wall top plates

Use 2×4 for the side supports of the lean to roof ends. Make a cut to one end of the supports and then lock them into place with 2 1/2″ screws.

Lean to sides supports

Use 2×4 lumber for the lean to sides of the roof. Drill pilot holes at both ends of the supports and lock them into place with 2 1/2″ screws.

Lean to side ends

Cut the panels for the lean to roof ends and then attach them into place tightly. Align the edges flush and insert 6-8d nails.

Fitting the roofing sheets

Cut the roof sheets from 3/4″ plywood and then attach them to the top of the shed. Align the edges flush, drill pilot holes and insert 1 5/8″ screws to secure them into place, every 8″ along the rafters.

Fitting the trims

Use 2×6 lumber for the side overhangs and 1×6 lumber for the front and back roof trims. Align the components with attention and secure the trims into place with 2″ brad nails.

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.
