  • Fitting the posts – Cut the posts at the right size, as you need to place them about 3′ below the ground.
  • Fitting the posts – Place the posts into place once all the markings are done. Dig 2-3′ deep holes and pour a 2″ layer of gravel into it. Fix tube forms and install the posts into place. Secure them with braces and fill the forms with concrete. Allow the concrete to dry for at least 2 days.

  • Fitting the support beams – Once the posts are fully set and the concrete is dry, install the 2×6 support beams on the top of the posts. Secure the beams on top of the posts with clamps. Insert 8” carriage bolts through the post and support beams into the previously drilled pilot holes. Ensure that no gap is left between the components, pack it together very tightly. Repeat the procedure for the other posts till you get a rigid structure.
  • Fitting the braces – Fit 4×4 braces to the flat roof carport for enhanced durability of the structure. Cut both the ends of the braces at 45 degrees and secure the braces to the structure. Ensure no gaps are left between components. Install the other support beams.
  • Building the rafters – Make the rafters with the 2×6 lumber. Cut the beams to the ideal size and smoothen the notches with sandpaper and remove any residue with a damp cloth.
  • Fitting the rafters – Place the rafters on the support beams and ensure they are equally spaced. Secure the rafters to the support beams with 5 1/2″
  • Fitting the exterior rafters – Fasten the 2×6 trims to the outside of the roof and secure them into place with 2 1/2″ Add glue to the joints to make it stronger and remove any excess glue with a damp cloth.

  • Fitting the roofing sheets – Attach 3/4″ tongue and groove plywood sheets to the roof and follow a certain pattern. Use a circular saw to adjust the size of the sheets, when required. Make even the sheets at both ends and secure them to the rafters with 1 1/2″ nails or screws, every 6-8″. Close the gaps between the sheets for a neat look.
  • Fitting the roof – To fit asphalt shingles, install roofing felt over the roofing sheets, and ensure that the strips overlap at least 2″. Arrange the tar paper to the plywood sheets with roofing staples. Align the side drip edges over the roofing felt, and the bottom drip edges should be placed under. Place a starting course at the bottom of the roof, before installing the asphalt shingles. Follow the instructions carefully while placing the asphalt shingles.
  • Finishing touches – Fill the holes with wood filler and allow to dry completely for several hours.

An affordable DIY carport is ready. Not only will it shelter your vehicle but will also offer a neat area to park your vehicle.
