Blue board and batten ranch home with white stone, cedar trim and a gray shingle roof

Pergolas in the Rio Grande Valley, TX

You stand under the staked outline in your yard before anyone digs. Mention a future roof or vines then, and we size the frame and footings for that load.

A pergola is open overhead framing on posts, with rafters spaced about 16 inches apart. It cuts part of the midday sun and none of the rain. Most pergolas go up in 2 to 3 working days, once the post footings have cured.

What the job includes02

What a porches and patio covers job with us includes

A pergola is the honest answer when you want shade but not a roof. Here it does less than people expect in July, because the sun is nearly overhead at midday. Rafters at 16 inches on center and a shade cloth on top change that. Wood in this climate needs sealing every 2 or 3 years, or the grain opens and the boards check. Aluminum skips that entirely.

Questions we get06

Questions homeowners ask us about this work

Does a pergola give usable shade in a Valley summer?

Partly. At 16 inches on center the rafters block a real share of the low morning and evening sun. At noon in July the sun comes almost straight down, so the shade is striped, not solid. A shade cloth or a louvered top fixes that if midday matters to you.

Can I add a solid roof to a pergola later?

Only if the posts and footings were sized for it from the start. A pergola frame carries its own weight, not a panel roof plus wind uplift. Tell David at the measure visit if a roof is coming later, and the posts and footings get built for that load now.

Can a pergola attach to the house, or does it stand alone?

Either one. Attached costs less because a ledger replaces two posts, and it keeps the yard open. Free standing works when the roof line is wrong or when you want the pergola out in the yard, away from the house.

How do you keep the post bottoms from rotting?

The post never touches concrete. It sits on a galvanized standoff base that holds the end grain about an inch clear, so water drains instead of wicking up. Posts set directly in a concrete footing are the ones that fail from the bottom in about ten years.

Will a pergola carry a bougainvillea or a grape vine?

A mature bougainvillea gets heavy and it holds wind like a sail. If you want vines, say so before we quote, because the beams and the footings get sized up. We also leave the rafter spacing open enough that you can prune from a ladder.
