Covered patio with a stone outdoor kitchen next to the breezeway between house and garage

Patio Covers in the Rio Grande Valley, TX

Sealant on top of shingle is what leaks, usually in the second rainy season. We bolt your cover into the house framing and flash the tie-in under the shingle.

A patio cover is a solid roof over your slab, attached to the house or set on its own posts. A 20 by 12 foot cover shades 240 square feet of concrete. Most attached covers go up in 3 to 4 working days after the footings cure.

What the job includes02

What a porches and patio covers job with us includes

West facing slabs take the worst of it here. From March to October the afternoon sun lands on the concrete and stays in it past sunset. A solid cover stops that before it starts. Hail in April dents thin sheet metal, so panels get screwed on a tighter pattern than a roof needs. Near the bay, the fasteners, not the panel, are what fail first.

  • Layout of the post line so the cover clears your doors and your windows
  • Footings dug below the loose caliche fill and poured with the post bases set
  • A ledger bolted into the band board, not screwed into the fascia trim alone
  • Beams and purlins sized for the span you picked, so the middle does not sag
  • Roof panels screwed on a tighter pattern than a house roof, for hail and wind
  • Flashing and sealant at the tie-in, then a hose test before we call it done
  • Gutter and downspout when the runoff would land against the house
Signs you need this work
  • The back slab is unusable from about 11 a.m. to 6 p.m. from June through September
  • Patio furniture fades, cracks and turns brittle inside one summer
  • The west facing sliding door heats the living room every afternoon after 3 p.m.
  • Rain runs off the house roof straight onto the slab and splashes the back wall
  • The old aluminum awning rattles, sags or has screws backing out of the wall
  • The grill and the tools live in the garage because there is no shade outside

Questions we get06

Questions homeowners ask us about this work

Can a patio cover attach to my roof without leaking?

Yes, when the ledger lands in framing and the tie-in gets real flashing under the shingle. Sealant on top of shingle is what leaks, usually in the second rainy season. We run a hose over the finished tie-in before we hand the job over.

Aluminum or wood for a patio cover in this heat?

Aluminum wins on maintenance, because it never gets sealed or painted and it does not warp. Wood wins on looks and on matching an older house. In full afternoon sun, aluminum with an insulated core stays cooler underneath than any wood frame with metal on top.

What size cover fits a standard Valley back slab?

A 20 by 12 foot cover shades 240 square feet, which is most of a typical back slab. That fits a table for six, two chairs and a grill with room to walk behind them. Go to 20 by 16 if you want a full outdoor kitchen under the roof.

Is an insulated panel worth it over a plain sheet?

It depends on how you use the patio. If you sit out there in July, the foam core is the difference between shade and comfortable shade. If the cover is there to keep sun off a work area or a vehicle, plain sheet does the job for less.

Can you add gutters so the runoff does not flood the yard?

Yes, and on most covers we recommend it. Without a gutter the whole roof dumps in one line along the slab edge. We run the downspout so it discharges at least 3 feet from the foundation, away from the door.
