Patio Covers and Pergolas in Antioch, CA
Antioch has some of the oldest housing in East County, and a lot of its patio covers are as old as the houses. Many projects here start with taking something down: a wood cover that has sagged, a fiberglass roof gone brittle, or a cover that was never permitted.

What's different about patio covers in Antioch
Aging wood covers
Wood covers built decades ago often have rot at the posts and the ledger, sagging beams or termite damage. Replacing them is often simpler than repairing them.
Brittle corrugated roofs
Old fiberglass and corrugated roof panels yellow, crack and leak. Swapping the roof alone rarely fixes an old frame.
Covers built without a permit
Unpermitted covers on older homes tend to come up at sale. A replacement built with a permit settles that question.
Newer hillside lots
Newer homes in southeast Antioch often have sloped or narrow yards, which affects footings, post heights and whether a freestanding structure fits.

Repair or replace an old cover?
Push on the posts at the base, look along the beam for a sag, and check where the cover meets the house. Soft wood at the bottom of a post, a ledger pulling away from the wall, or water stains on the stucco under it mean the structure is failing, not just the finish. At that point a new cover usually costs less over time than repairs. Sound framing with a tired roof can sometimes be re-roofed. A contractor can tell you which after looking at it.
What a replacement involves
- Demolition and haul-away of the old cover. Ask for it as its own line on the quote.
- Wall repair where the old ledger was attached: stucco patching and flashing.
- New footings if the old posts were set in the slab or in rotted footings.
- A permit for the new cover, through Antioch's Building Division (opens in a new tab).
- The new cover: usually aluminum, which removes the rot and termite problem for good.
Wood again, or aluminum?
Many owners replacing a rotted wood cover switch to embossed, wood-grain aluminum: it looks similar from the yard and needs only washing. Wood is still a good choice for a pergola if you are willing to refinish it every few years. The comparison is on aluminum vs wood patio covers.
Permits in Antioch
Antioch sets its own rules for patio covers and pergolas. Check with the city's Building Division (opens in a new tab) before planning, and do not assume Brentwood's or Oakley's numbers apply. Your contractor will normally pull the permit; make sure the quote says so.

Patio covers in Antioch: common questions
Should I repair or replace my old wood patio cover?
If the posts are soft at the base, the beam sags, or the ledger is pulling away from the house, replacement is usually the better value. Sound framing with only a worn roof can sometimes be re-roofed.
Do I need a permit for a patio cover in Antioch?
Check with the City of Antioch's Building Division, which sets the rules for patio covers and pergolas there. Contractors usually pull the permit as part of the job.
What does it cost to replace a patio cover in Antioch?
The new cover follows the national ranges, about $20–$50 per square foot for aluminum (HomeGuide), plus demolition, any wall repair and new footings. See the cost guide.
