A free standing lean to roof is a great DIY project for those who want to add some extra storage or shelter to their backyard without breaking the bank.
You can build a free standing lean to roof for as little as $500, depending on the materials you choose.
The design of a free standing lean to roof is relatively simple, with a sloping roof and a wall that leans against a fence or wall.
To ensure stability, you'll want to use a sturdy base and anchor the structure to the ground.
The key to a successful DIY project is to plan carefully and measure twice before cutting any materials.

Planning and Preparation
Before starting your free-standing lean-to roof project, take some time to think about how you plan to use it. Will it just be additional covered parking for a vehicle?
Determine the purpose of your lean-to roof to ensure it meets your needs. You can use it for storage, working outdoors, or even as a shaded area for outdoor activities.
Consider the size of the lean-to roof based on the space you have available and the purpose it will serve. A larger roof may provide more storage or working space.
Think about the location of your lean-to roof, taking into account the direction of the sun and the wind. This will help you determine the best orientation for your roof.
Plan the design and layout of your lean-to roof, including the type of materials and the style of the roof. This will help you visualize the final result and ensure it fits with your overall design.

Building the Structure
To start building your free standing lean to roof, you'll need to prepare the ground first, which may not require a man-made foundation depending on the ground's condition.
A key component of the structure is the walls, which are framed using 2x4 lumber. You'll need to frame each wall by nailing together 2 2x4 beams for the top and sides, with the bottom of the wall being a single 2x4 beam.
When framing the walls, make sure to measure each beam before cutting or nailing them together to ensure proper framing. For example, a 12 by 16 feet shed requires framing the walls with 2 2x4 beams for the top and sides, and a single 2x4 beam for the bottom.
You'll also need to attach joists at 22 inches intervals within each framed wall, using 2 ½-inch screws to secure them to the doubled-up 2x4s of the frame.
To leave space for the door, double up 2 2x6 boards on either side of the door opening, and make sure to leave a 21 inch gap in the front wall.
The side walls are raised and attached to the framed floor using 2 ½-inch screws, spaced 8 inches apart, while the front and back walls are raised and attached using the same screws.
Once the walls are in place, you can attach siding to the walls using 2-inch nails, spacing them out by about 12 inches and driving them directly into the joists.
