You’d rather know whether a patio cover costs $9,000 or $40,000 before you book anything. Fair. Here are honest ranges from what we quote across Round Rock and Williamson County, what moves the number on a typical two-story lot, and how to compare quotes that look alike but aren’t.
Typical costs in Round Rock
For an attached cover over a residential patio, roughly 12 by 20 feet, installed and permitted with the City of Round Rock:
- Insulated aluminum patio cover: roughly $10,000 to $20,000. The most common cover in Williamson County and the best value per square foot of shade.
- Wood patio cover with shingle or metal roof: roughly $15,000 to $35,000, higher with finished ceilings and stone columns.
- Cedar pergola: roughly $6,000 to $15,000; aluminum pergolas somewhat more.
- Motorized louvered pergola: roughly $25,000 to $60,000.
- Adding screens: roughly $5,000 to $15,000 depending on wall area and mesh.
- Three-season sunroom: roughly $25,000 to $70,000; four-season rooms with insulated glass and HVAC cost more.
- Slab extension: commonly needed in Round Rock; priced by area and finish and usually a modest fraction of the cover.
Ranges, not quotes. Two Teravista houses with the same floor plan can differ by thousands for the reasons below.
What moves the price on a Round Rock lot
- Extending the slab. Most builder patios here are 10 by 10 or 12 by 12. A cover the width of the house needs a bigger slab, so the concrete is often line one on the quote.
- Two-story attachment. Attaching below second-floor windows takes more care than a single-story fascia. Some floor plans push us to a freestanding design.
- Size and roof style. Flat (single-slope) is the baseline; gable and hip roofs add height and cost.
- Material and finish. Panel thickness, wood species, ceiling finish and column type (aluminum post vs. stone column).
- Electrical. Fans, lights and outlets need a licensed electrician and a permit. Budget a few thousand for a fan-and-lights package.
- Permit and engineering. Included in our quotes; city fees passed through at cost. A quote without them isn’t cheaper, it’s incomplete.
What every quote should include
- Dimensions and a drawing
- Material spec: panel thickness, wood species, roofing, finish colors
- Roof style and attachment method
- Posts or columns, number and type
- Electrical scope and who performs it
- Engineering, HOA submission and City of Round Rock permit
- Concrete work, if any
- Warranty terms, workmanship and manufacturer
- Proof of general liability and workers’ comp insurance
Where Round Rock homeowners over- and underspend
Overspend: choosing wood for a household that won’t re-stain it, or a louvered roof on a patio that’s shaded by afternoon. Underspend: covering only the builder’s slab instead of extending it, skipping the fan, and skipping the conduit that would have made lights cheap later.
