Instructions

Determine the size and location of your patio cover. The size of your patio cover will depend on the size of your patio and the amount of coverage you want. You should also consider the location of your patio cover. Make sure it will not block any windows or doors and that it will not be too close to any trees or other obstacles.
Dig the holes for the posts. The holes should be dug at least 2 feet deep and 1 foot wide. The posts should be set in concrete.
Set the posts in the holes. Make sure the posts are plumb and level. Backfill the holes with concrete and tamp it down firmly.
Attach the beams to the posts. The beams should be attached to the posts with galvanized nails or screws. Make sure the beams are level and square.
Attach the joists to the beams. The joists should be spaced evenly apart. The joists should be attached to the beams with galvanized nails or screws.
Install the roofing. The roofing can be corrugated metal, asphalt shingles, or polycarbonate panels. The roofing should be attached to the joists with galvanized nails or screws.

Tips

Use pressure-treated lumber for all of the components of your patio cover. This will help to protect the wood from rot and decay.
Make sure all of the joints are securely fastened. This will help to ensure that your patio cover is strong and durable.
Caulk all of the seams and joints. This will help to prevent water from leaking through your patio cover.
