12x24 Lean to Shed Roof Plans

This step by step diy project is about 12×24 shed roof plans. This is PART 2 of the storage shed project, where I show you how to build the lean to roof and to make and attach the double doors. Take a look over the rest of my woodworking plans, if you want to get more building inspiration. Remember that you need to select the site for the shed with attention and that you have to comply with a few legal regulations.

When buying the lumber, you should select the planks with great care, making sure they are straight and without any visible flaws (cracks, knots, twists, decay). Investing in cedar or other weather resistant lumber is a good idea, as it will pay off on the long run. Use a spirit level to plumb and align the components, before inserting the galvanized screws, otherwise the project won’t have a symmetrical look. If you have all the materials and tools required for the project, you could get the job done in about a day. See all my Premium Plans HERE.

Building a 12×24 lean to shed roof

rafters-for-12×24-lean-to-shed

The first step of the lean to roof project, you need to build the rafters from 2×6 lumber. Therefore, mark the cut lines on the beams and then get the job done with a saw. Make sure you take accurate measurements, otherwise the rafters won’t fit into place tightly.

Fitting the rafters to the shed

Fit the rafters to the top of the shed. Place the rafters equally spaced, every 16″ center. Use rafter ties to lock the rafters into place tightly.

Roof sheets – 12×24 shed

Cut the roof sheets at the right dimensions, and fit the 1/2″ plywood sheets to the roof of the lean to shed. Align the edges with attention and insert 1 5/8″ screws, every 8″ along the rafters. Make sure you leave no gaps between the sheets.

Side supports for the lean to roof

Use 2×4 lumber for the lean to side supports. Make the angle cut to the top of the supports. Lean to pocket holes at both ends and secure it into place with 2 1/2″ screws.

Side panels – 12×24 lean to shed

Cut the panels for the sides of the shed. Align the edges flush and leave no gaps between the panels. Insert 2″ nails every 8″ along the framing.

Side trims – 12×24 shed

Fit 2×8 trims to the sides of the roof. Lock them into place with 3 1/2″ screws. Fit the 2×8 trims to the front and back of the roof. Insert 3 1/2″ screws to lock the trims into place tightly.

Front and back roof trims

Fit the 1×8 trims to the front of the shed. Align the edges and leave no gaps between the trims. Use 3 1/2″ screws to secure the trims into place.

Fitting the roofing to the 12x24 lean to shed

Fitting the roofing to the 12×24 lean to shed

Cover the roof with tar paper and then install the asphalt shingles. Make sure you also install the appropriate drip edges, so you can seal the shed roof. Read the manufacturer’s instructions for a tight fit.

Shed-door

Use 2×4 lumber for the door frame and T1-11 siding sheets for the door panels. Drill pocket holes and assemble the door frame on a level surface. Measure the diagonals and make sure they are even. Check if the corners are square. Attach the T1-11 siding sheets and insert 1 1/4″ nails to secure the panels into place tightly.

Fitting the door jambs

Fit the 2×4 jambs to the front of the shed, around the opening. Drill pilot holes and insert 3 1/2″ screws to secure the jambs into place tightly.

Fitting the double doors

Fit the doors to the front of the shed. Align the edges flush and attach hinges to secure the doors to the jambs. Install a latch to lock doors.

Fitting the trims to the walls

Use 1×4 trims for the corner trims. Make the angle cuts and then fit the trims to the corners of the shed with 2″ nails. Leave no gaps between the trims.

Window trims

Fit the 24″x32″ windows to the front of the shed. Attach the trims around the windows. Make sure you take a look over PART 1 of the project, so you learn how to build the frame of the shed.
