This step by step diy project is about 12×24 carport gable roof plans. This is PART 2 of the large lean to carport project, where I show you how to build the roof and how to attach the decorative trims. This carport is ideal if you want to save space in your yard or place it near the property line. You can even easily modify my plans and turn it into an attached carport. 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. See all my Premium Plans HERE.

How to build a 12×24 lean to carport roof
The first step of the project is to build the rafters for the single car carport. Therefore, you should use 2×6 lumber. Mark the cut lines on the beams and then get the job done with a saw. Smooth the edges with sandpaper for a professional result.
Fit the rafters to the top of the single car carport, making sure you place them every 16″ on center. Use a spirit level to plumb the trusses and lock them to the support beams with rafter ties.
Attach 3/4″ plywood sheets to the top of the carport. Start with the bottom left section of the carport and go up to the top. Leave no gaps between the sheets and secure them into place with 1 5/8″ screws or nails. Ideally, you should use tongue and groove roof sheets.
Fit 1×8 trims to the sides of the carport, so you cover the ends of the rafters. Use 2″ brad nails to secure the trims into place. Align the edges with attention for a professional result.
Install the roofing felt, starting from the bottom left of the roof. Secure the paper to the roofing, using a stapler. Make sure the tar paper overlaps at least 2”. Don’t forget to cover the top ridge with a 14” strip of paper. Start the first course of shingles with a full tab, the second with 2 1/2 tabs, the third with 2 tabs, the forth with 1 1/2 tabs, the fifth with 1 tab, the sixth with half tab and the seventh with a 3 tabs.
Last but not least, fill the holes with wood putty and let it dry out for a few hours. Sand the whole surface with sandpaper and then apply a few coats of paint or stain to enhance the look of the carport and to protect the components from decay.
This project can be built in less than one week and it will serve you for many, many years in a row. This large carport is easy to build and fairly budget friendly. I recommend you to read the local building codes before starting the project, so you make sure you comply with the local building codes. Check out PART 1 of the project.

Is it possible to build this with more soffit overhang to protect boat from sun and dirt splashing when it rains? I need a minimum of 11′ of clearance from inside post to inside post so i can easily back my boat in. The boat is a minimum of 25′ with tongue folded… I really need a 12 X 26 plan… Do you have that?
I don’t have that, but you can easily add 1′ overhangs to the front and back of the carport,
Can you tell me approximate how much something like this would weigh.
And just for reference an approximate cost?
I need a 24′ by 30′ lean to attached addition to my barn. how could I adapt this plan?
24 ft is a large span. You need posts on the middle to support the rafters. Other than that, use the same techniques shown in the plan and check the local codes.
