Pergola Cost: Average Prices & Cost Factors

A pergola is an open-roofed frame of posts and beams that defines an outdoor space and casts partial shade. Cost depends on size, the material, the style of roof, and whether you buy a kit or have a carpenter build it from scratch.

The same footprint can cost several times more or less depending on those choices, so start with the size you need and the amount of shade you want.

Larger pergolas need more lumber, bigger posts, and often deeper footings. The ranges below are for installed pergolas and span the cheapest to the most expensive materials.

Pick a size based on how you will use it. A pair of chairs fits in a small one, while a dining table needs room to pull chairs out.

Material changes both the upfront price and the upkeep.

• Pressure-treated pine: Affordable and easy to work with. Needs periodic staining or sealing to resist weather.
• Aluminum: Low maintenance and does not rot, and often sold as prefabricated systems.
• Fiberglass: Strong and weather resistant, and priced at the top of the table.
• Cedar and other woods: Natural resistance to decay and a warm look. Other woods can be priced higher than pine.

A traditional pergola has open rafters. Adding a cover turns it into a shaded room and changes the price.

A solid roof blocks rain and sun but needs stronger framing and, in many places, a building permit. Louvered roofs, which tilt to control light, include motors and wiring, which is why they sit at the high end.

Buying a kit saves on design and carpentry. Hiring a pro to build from scratch gives a custom size and shape.

Some towns require a permit for any freestanding structure, others only above a certain size or height, and most want setbacks from property lines. If the pergola attaches to your house, rules are stricter. Call your building department before you buy materials.

A small kit is a realistic weekend project for two people who are comfortable with tools. The challenge is anchoring. Posts need to be plumb and secured to concrete footings or a solid slab, or the structure can shake in wind. Attaching a pergola to a house requires finding the framing and flashing the connection to prevent leaks. If you are unsure, hire a licensed contractor for the structural parts.

• Site prep: Leveling a slope or removing sod before the build.
• Foundation. Footings versus a bolt-down on an existing patio.
• Extras: Lighting, ceiling fans, curtains, and climbing plant supports.
• Design details: Curved beams, decorative post bases, and cut ends cost more labor.
• Local labor rates: Carpenters price differently by region.

The two sources below start from the same low end but differ at the top. One may lean toward standard wood designs, and the other includes premium materials and larger sizes. Treat the average as a middle point, not a target.

• Is the quote for a kit or a custom build, and which materials?
• What footing depth and anchoring method will be used?
• Does the price include permits and cleanup?
• How will the wood be finished, and how often does it need resealing?
• What warranty covers workmanship and materials?
