10x10 Lean to Shed Roof Plans | HowToSpecialist - How to Build, Step by Step DIY Plans

This step by step woodworking project is about free 10×10 lean to shed roof plans. This is PART 2 of the garden lean to shed project where I show you how to frame the roof and how to build the front door. The lean to roof is the ideal choice if you want to build it near the property line. The double shed doors will give you a quick and wide access to the interior of the shed. 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 HERE.

How to build a lean to shed roof for a 10×10 shed

Front wall panels – 10×10 shed

Use 5/8″ T1-11 siding sheets for the exterior of the shed. Attach the panels to the exterior of the shed and align the edges flush. Insert 6d nails to secure the panels to the framing of the shed. Use a saw to make the cuts around the openings.

Back wall sheets

Attach the sheets to the back of the shed. Align the edges flush and leave no gaps between the sheets. Insert 6d nails every 8″ along the framing.

Rafters

Build the rafters for the lean to roof using 2×6 lumber. Mark the cut lines on the slats and get the job done with a circular saw. The birdsmouth cuts are needed so you can fit the rafters into place tightly.

Fitting the rafters – 10×10 lean to shed

Fit the rafters every 16″ on center and align the edges with attention. Drill pilot holes and insert 3 1/2″ screws so you can secure the rafters to the top plates.

Side wall panels

Use T1-11 siding for the side walls for the shed. Make the cuts to the sheets and then align them into place. Use 6-8d nails, every 8″ along the framing.

Overhangs – 10×10 shed

Build the overhangs for the sides of the shed using 2x6s. Drill pilot holes through the beams and insert 3 1/2″ screws into the blockings. It is really easy to to adjust the size of the overhangs to suit your needs.

Fitting the side overhangs

Fit the overhangs to the sides of the shed and align the edges flush. Drill pilot holes through the overhangs and insert 3 1/2″ screws to lock them into place tightly.

Roof sheets – 10×10 lean to shed

Cut and fit the 1/2″ plywood sheets to the top of the shed roof. Align the edges flush and insert 1 5/8″ screws, every 8″ along the rafters.

Side roof trims

Fit the 1×8 trims to the sides of the shed. Align the edges flush and insert 2″ nails to lock them into place tightly.

Front and back roof trims

Fit the 1×8 trims to the front of the shed roof. Lock them into place tightly with 2″ 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.

Door jambs

Fit 2×4 jambs around the door opening. Align the boards with attention and then lock them into place tightly with 2 1/2″ screws.

Door – 10×10 shed

Build the door for the lean to shed from 2×4 lumber and T1-11 siding. First, you need to make the frame for the door from 2×4 lumber. Drill pocket holes and assemble the door frames together tightly with 2 1/2″ screws. Make sure the corners are square for a neat result. Attach the T1-11 siding that you have cut out in the previous steps and lay them over the door frames. Use 2″ nails to secure the panels to the frames tightly.

Fitting the door

Fit the door to the front of the garden shed. Align the edges with attention and lock them to the jambs with hinges. Attach a latch to lock the door.

Back wall trims

Use 1×4 lumber for the exterior corner trims. Make the angle cuts and then attach them into place with 2″ nails.

Front wall trims – 10×10 lean to shed

Fit the window to the opening and then you can attach 1×4 trims to enhance the look of the shed.

Last but not least, you need to take care of the finishing touches. Therefore, fill the holes with wood putty and then smooth the surface with sandpaper. Apply a few coats of paint or stain over the components to enhance the look of the shed and to protect the components from decay.
