How to Build a Patio Cover With Cedar or Cypress

Patio Cover Frame Construction

• Lay out the dimensions and style of the cover on graph or blueprint paper. If the cover is attached to a structure, the square footage should be equal or less than the abutting roof to create a balanced appearance. The supporting poles can be inserted in the ground around the perimeter of the patio or into holes drilled into the patio base. Use an adequate number of poles to support the cover during storms and high winds. Create a lattice framework between the poles with lumber strong enough to support the cedar or cypress planks. For maximum coverage and protection, make the distance between the supports slightly smaller than the dimensions of the planks.

Cedar Covers

• Cedar is available in various grades but none is strong enough to build structures. Cedar is attractive, durable and resists rotting and insect infestation. To retain its natural, rich, golden brown color, treat cedar with a clear finish as sun and rain will turn it a dull grey. Older cedar with a solid color surface is stronger than streaked cedar or sapwood. Use small nails to apply it to the substrate to prevent splitting the wood.

Cypress Covers

• Cypress is sold in common and premium grades and sturdy enough to be used as construction lumber. Most lumber yards in the southeastern part of the country stock cypress, but it may need to be specially ordered in other areas. It retains its light brown, reddish hues in all types of weather. Cypress is rot- and insect-resistant but will warp and curl over time if not properly dried and cured before installation. As a patio cover, cypress wood can be attached to the lattice base with screws or nails.

Tips and Hints

• Slightly overlap cypress or cedar planks to allow adequate air flow so the patio cover can “breathe” and is impervious to being lifted or torn by strong winds. Cedar is typically about half as expensive as redwood and twice as costly as pressure treated lumber. If you live in a region far away from natural cypress sources, it can cost more than redwood. For maximum savings, consider mixing wood types for your patio cover.
