Covered Patios & Pergolas in Wentzville, MO

Pergola, patio roof or pavilion

A pergola is an open frame of posts, beams and rafters. It filters sun without blocking rain, and can take a retractable canopy or louvered roof. A patio cover is a solid roof attached to the house, framed and shingled to match or finished in standing-seam metal. A pavilion is a freestanding roofed structure out in the yard, by a pool or a fire pit. Solid roofs give true all-weather use and are engineered and permitted like any roof.

Structure still matters

Open or not, these structures catch wind. Posts need real footings below frost and hold-down hardware, not brackets screwed into a four-inch patio slab. We core or cut the slab and pour proper piers where a new structure lands on existing concrete. For attached roofs, the connection to the house gets the same flashing attention as any addition. Materials range from cedar and Douglas fir timbers to pressure-treated frames wrapped in PVC trim, to powder-coated aluminum.

Building out the space

Once there is a roof, everything else follows: a ceiling fan, recessed or pendant lighting, outlets for a TV or a smoker, a gas line for a grill or fire feature, infrared heaters. We run electrical in conduit or inside wrapped posts so nothing is exposed. If a new patio, a larger slab or a stamped or paver surface is part of the plan, we coordinate that under the same contract.

How the work runs

1. Site and sun studyWhere the sun is at the hours you use the patio decides placement and roof style.
2. Design and permitDrawings, structural sizing, building permit and HOA approval.
3. Footings and framePiers, posts, beams, rafters and any roof deck.
4. Roofing, electrical and finishShingles or metal, wiring, stain or paint, fans and lights.

What moves the price

We do not publish square-foot prices, because they mislead more than they help. These are the factors that actually change the number on a proposal.

• Open pergola versus solid roof.
• Timber species and size. Large cedar or fir timbers are a premium.
• Attached versus freestanding.
• Electrical, gas and any new patio surface.

How long it takes

Pergolas take about a week. Roofed patio covers and pavilions take two to four weeks.

Permits

Solid-roof structures and most attached pergolas require a permit. Small freestanding pergolas sometimes do not, depending on the city. See our guide to which projects need a permit.
