Lean to Shed Roof Plans

This step by step diy project is about 8×12 lean to shed roof plans. This is PART 2 of the lean to shed project, where I show you how to build the roof and the double front doors. This shed is a nice addition to any backyard, as a homeowner has always lots of items to store and shelter against the elements. Take a look over the rest of my woodworking plans, if you want to get more building inspiration.

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.

Building a roof for a 8×12 shed

Building-the-lean-to-rafters

The first step of the PART 2 project is to build the rafters for the lean to shed. Mark the cut lines on the 2×4 beams and get the job done with a circular saw. Smooth the cut edges with sandpaper and cut the top end at 70 degrees (make a 20 degree cut).

Fitting-the-rafters-lean-to-shed

Fit the rafters to the top of the shed and place them equally-spaced, every 24″ on center. Drill pilot holes through the rafters and insert 3 1/2″ screws to secure them to the top plates.

Side support

Next, you need to build the frame for the side top ends. Cut a piece of 2×4 lumber at 88 1/2″. Next, cut one end of the support at 20 degree (make a 70 degree cut) and secure it to the top plates of the side walls. Drill pilot holes and secure the supports into place with 2 1/2″ screws. Add glue to the joints for a professional result.

Fitting the side supports

Continue the project by attaching the vertical supports to the side rood ends. Cut the top of the 2×4 support at 70 degree (make a 20 degree cut) and secure it to the framing with 2 1/2″ screws, after drilling pilot holes.

Fitting the side panels

Continue the project by attaching the T1-11 siding sheets to the sides of the lean to shed. Leave no gaps between the sheets and align the edges flush for a professional result. Use 4d nails to secure the sheets into place tightly.

Fitting the roofing sheets

Attach the 3/4″ plywood sheets to the roof of the lean to shed. Align the edges flush and secure them to the rafters using 1 5/8″ screws. Make sure there are no gaps between the sheets for a professional result.

Roof side trims

Fit the 2×6 trims to the sides of the roof. Cut the top edge at 70 degrees (make a 20 degree cut) and secure them into place with 2 1/2″ screws, every 8″.

Fitting the front trim

Fit a 1×6 trim to the front of the lean to shed, as shown in the diagram. Align the edges with attention and secure it to the ends of the rafters using 2 1/2″ brad nails.

Fitting the roofing

Cover the roof of the shed with roofing felt, 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. Afterwards, attach the asphalt shingles to the roof, starting with the left bottom side of the roof. Read the manufacturer’s instructions to understand how to install the shingles into place properly.

Fitting the door jambs

Attach 1×4 trims around the door opening, as shown in the plans. Align the edges flush and then secure the trims into place with 1 1/2″ brad nails and glue.

Building the doors

Build the doors from 1×4 trims and from T1-11 siding. Cut the door panels at the right dimensions using T1-11 and a circular saw. Then attach the 1×4 trims to the door panels, after aligning the edges flush. Add glue to the joints and insert 1 1/4″ nails to secure the them into place tightly.

Fitting the doors

Fit the doors to the front opening and align the edges flush. Use hinges to secure the doors to the jambs and a latch to lock the doors together tightly.

Fitting the side trims

In other to enhance the look of the lean to shed, you need to attach 1×4 trims to the sides. Cut the trims at the right dimensions and secure them into place with 1 1/2″ brad nails.

Fitting the front trims

Next, attach the 1×4 trims to the front of the shed. Leave no gaps between the components for a neat result.

How to build a lean to shed

Seen from one side, the lean to shed has a neat shape and a nice design. This type of shed is ideal if you want to attach it to an already existing building and therefore save some important space. In addition, another option would be to build this shed against the property fence.

How to build a 8×12 shed

This is a simple project you should be able to build in a few days without much effort.After building the roof and the doors for the shed, you need to take care of the finishing touches. Fill the holes with wood putty and let it dry out for a few hours. Smooth the surface with sandpaper and then paint the components, so you protect them from the elements and to enhance the look of the project.
