The first step of the project is to layout the single carport. As you can notice in the image, you need to use batter boards and string. After fitting them into place, we recommend you to check if the corners are right angled, by applying the 3-4-5 rule to each corner.
Top Tip: In addition, adjust the position of the string until the diagonals are equal. Dig 2-3′ deep holes.
There are several options when fitting the posts of the carport. As you can see in the image, the best option is to dig 2-3 deep holes (at least 6″ under the frost line) and set the posts into concrete.
Top Tip: We recommend you to plumb the posts with a spirit level and to secure them temporarily with 2×4 braces, before filling the tube forms with concrete. Let the concrete to dry out for several days.
The next step of the woodworking project is to attach the 2×6 support beams to the posts. As you can see in the carport plans free, you should attach the beams to the posts with several C-clamps, after leveling them.
Drill pilot holes trough the components and lock the beams to the posts with several 5 1/2″ carriage bolts. Use washers and make sure you don’t over-tighten the nuts.
Although this step is not compulsory, we strongly recommend you to attach 4×4 braces to the posts, as in the image. Cut the ends of the braces at 45º and lock them to the posts and beams with 3 1/2″ galvanized screws.
Always drill pilot holes before inserting the galvanized screws, to prevent the wood from splitting. In addition, add waterproof glue to enhance the rigidity of the joints.
Attaching the rafters into place is a straight forward process, but you need first to cut their ends as in the plans. Use 2×4 lumber to build the rafters and cut their ends at about 10º.
Top Tip: If you want to get a professional result, we recommend you to take accurate measurements and to cut the ends of the rafters at about 10º, using a miter saw. Work with attention and plan everything from the very beginning.
You need to place the rafters equally spaced, every 24″ on center. As you can notice in the plans, we recommend you to fit the rafters between the beams. Drill pilot holes trough the 2×6 beams and insert 3 1/2″ galvanized screws into the rafters.
We strongly recommend you to ask a friend to help you when building the roof of the carport, as one person needs to hold the rafters into place, while the other one inserts the screws.
Attach 3/4″ plywood sheets on top of the rafters, starting with the bottom part of the roof. It is essential to adjust the size of the tongue and groove sheets using a good circular saw, before securing them into place.
Align the sheet at both ends and insert 1 1/4″ screws into the rafters, every 6-8″. Make sure the sheets cover the support beams and there are no gaps between the plywood sheets.
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.
If you really want to enhance the look of the carport, we recommend you to attach 1×6 trims to the front and back faces of the carport. As you can easily notice in the image, we recommend you to cut the ends of of the trims at 10º and lock it to the rim rafters with 1 1/4″ finishing nails.
Align the trims at both ends before inserting the finishing nails, if you want to get a carport with a nice appearance.
Last but not least, you should take care of the finishing touches. Fill the gaps with wood putty and let the compound dry out for several hours, before sanding the surface with 120-grit sandpaper. Clean the surface with a cloth and apply several coats of wood stain, to protect the wood from rot.
Top Tip: You could fit lattice panels between the posts, if you want to protect your car from bad weather. In addition, the panels would add character to your construction.
