A slanted shed is just what it sounds like: a shed that leans against the wall of a house, garage, or barn for support. Lean-to huts are ideal for storing mowers, stoves, garden supplies, and other items that require cover but do not require a standalone structure. Most slanted have open ends for convenient access. They consist of two parallel walls joined by a roof. Lean-to sheds can be designed to match a home or garage, or they can be built with their own siding and roofing, which is frequently made of corrugated metal.

A Step By Step Guide to Building a Slanted Roof Shed

1. Gather the Necessary Tools

The first step in building a slanted shed is to gather the tools you will need:

  • Power miter saw
  • Handsaw
  • Power screwdriver
  • Pneumatic nail gun
  • Handsaw
  • Rags for cleaning up sawdust

2. Check Your Local Regulations

Sometimes, a property owner or a city will have regulations on the size of the slanted shed roof that you build. It is a good idea to check with these people before you construct the slanted shed. In some cases, it may be necessary to get a building permit.

3. Design the Roof

The next step in building a slanted shed is to design the roof. This will vary based on what type you want. A simple roof can be built by sheathing the roof rafters with plywood or OSB and then covering them with a layer of plywood. This method creates a simple shed roof.

If you want a steeply pitched roof, you can use a truss system to support the roof. This will require more materials, but it is worth it if you want a steep roof.

4. Determine the Right Shed Location

The next step in your construction is to determine the right location for your slanted shed. This will largely depend on the size of the shed. If you plan to build a large and bulky shed, you will want to build it in a location that is close to and right up against the house or garage. If you plan to build something smaller, you will want to build it on the side or the back of the yard.

5. Prepare the Construction Site

Once you have determined the best location for your lean-to, it’s time to prepare the construction site. This involves cleaning up the site and adding any additional items that might be necessary. If you are building a large shed, you will want to dig a hole for a floor. This is also a good time to start laying out the foundations for the shed in preparation for the actual construction.

6. Build the Shed Foundation

Once you have prepared the foundation for your shed, it’s time to start building it. This will involve putting the foundation together and then adding the walls. If you are building a large shed, the walls need to be built on the ground and lifted into place. After the shed walls are in place, you can install the windows, doors, vents, and any other items. Finally, you will add the floor.

7. Build the Floors and Walls

The next step in the building process is to add the floors and walls. If you are building a large shed, you will want to frame the walls and then raise them into place. You may want to add temporary support beams and buttresses to hold the walls in place until you get them secured. For smaller sheds, the walls and floor can be put in place at once. This typically requires only one or two-floor supports.

8. Construct the Slanted Roof

The next step in your construction is to build the roof and put the roof shingles on. This is normally a very basic process. If you are using a truss system, you will have to install the trusses and then cover them with roofing materials and then the roof shingles. If you are building a simple roof, you will need to frame the roof and then install the roofing materials and shingles.

9. Install Siding

The last step in building a lean-to shed is to put siding on it. This will give the shed a more finished look. It will also protect the framing from the elements. There are numerous siding materials that you can use. Any of them will work. It will primarily depend on your taste, the style of the home, and your budget.


The slanted shed is a simple, small, and effective type of shed for those who don’t want to or can’t invest in a more elaborate shed. It is perfect for smaller spaces and can be very easily modified. The slanted shed is also a great way to finish the yard of a house or a garage.
