If you want to protect your car from the elements without the expense of adding a garage, building a carport is a practical solution. This is not an unrealistic job for the average do-it-yourself enthusiast to tackle. The instructions below are for a carport that is 10 feet wide and 20 feet long, but you can easily make the necessary modifications to create a carport that better suits your needs.  


Step 1: Install Posts

There are three basic ways you can install the posts. The first is to dig the post holes and put the posts directly into the holes or fill the holes with concrete. Either way make sure that the posts are completely vertical by using a string line to test them. The second method is to fill the post holes with concrete and set galvanized post brackets into the concrete before it hardens. The third method is to fix the brackets to the concrete slab using of masonry bolts or anchors.

Step 2: Trim Posts

Now it's time to trim the posts, making sure that the rear posts are approximately 7 1/2 feet higher than the ground or the slab. Make sure that the posts are all level with one another. You can use a spirit level to get the straight edges right. Make sure to measure the front posts approximately 4 inches higher than the back posts, cutting the posts off at their marks.

Step 3: Attach Beams

Attach the beams, taking two beams and cutting them to 20 feet in length, then cut a 45-degree angle in each of the ends and place them in such a way that the tops of the beams are flush with the tops of the post. Clamp them down and bolt them in place with your drill.

Step 4: Cut Rafters

Cut the rafters with 45-degree angles at each of the ends that were previously cut to length. Make sure that they are nailed flush alongside the beams and are reinforced using galvanized brackets. Cut 6 more rafters and then fix them to the beams using joist hangers that are about 3 feet apart from one another.

Step 5: Brace Posts

Next you will want to brace the posts if they were not cemented into the ground. Take a few of the lengths of wood, bracing them diagonally between one post and another in order to create greater support on all sides.

Step 6: Attach Roof

Now you can attach the roof properly. This simply involves nailing down the roofing material that you chose. You are going to want to insert a few well-placed screws, meaning that weaker areas should have screws attached to keep them in place and create more strength.
