Pergola Material Costs
Material is the second-biggest cost driver after size. These are material prices per square foot, before labor.
| Material | Material cost per sq ft | Source |
|---|---|---|
| Aluminum or vinyl | $10 to $30 | HomeGuide |
| Pine or pressure-treated pine | $20 to $40 | HomeGuide |
| Cedar | $25 to $40 | HomeGuide |
| Redwood | $40 to $50 | HomeGuide |
| Fiberglass | $50 to $70 | HomeGuide |
Which material works best in Houston?
Houston's heat, humidity and heavy rain are hard on wood. Cedar is a popular choice because it naturally resists rot and insects, and it looks warm and natural. It still needs a stain or sealer every few years.
Aluminum does not rot or rust, which makes it low-maintenance in humid weather. Powder-coated finishes come in many colors. Pressure-treated pine is treated to resist rot and costs less, but it can warp or crack as it dries, so it needs more care.
What Changes the Price of a Pergola
1. Size
A bigger footprint means more posts, beams and rafters. A 10x10 pergola and a 16x20 pergola are very different jobs.
2. Kit vs. custom build
Kits are cheaper, but they come in set sizes. A custom pergola is built to fit your patio, your roofline and your view. It usually uses heavier posts and beams too.
3. Attached vs. freestanding
An attached pergola uses your house for support on one side, so it needs fewer posts. A freestanding pergola needs its own posts and footings on all sides. Attaching to a house also has to be done carefully to protect your roof and siding.
4. Footings and ground conditions
Posts need solid concrete footings. On Houston clay soil, which swells when wet and shrinks when dry, good footings keep the pergola level over time. Setting posts on an existing patio may need special anchors or new footings.
5. Shade and roof options
A basic open-slat roof is the least expensive. Adding shade cloth, a polycarbonate panel roof or a louvered roof adds cost. Louvered roofs let you open and close the slats for sun or rain.
6. Fans, lights and electrical
Ceiling fans, string lights, recessed lights and outlets all need wiring. Electrical work usually needs a licensed electrician and may need its own permit.
7. Permits and HOA approval
Many Houston-area cities require a building permit for a pergola, especially if it attaches to the house. HOAs often need to approve the design as well. Read our guide on whether you need a permit for a pergola in Houston before you start.
Pergola vs. Patio Cover: Which Costs More?
A pergola has an open roof that gives partial shade. A patio cover has a solid roof that blocks sun and rain. Solid roofs need more framing, roofing and gutters, so they usually cost more.
If you want to stay dry during summer storms, compare prices in our patio cover cost guide. If you want airflow and a lighter look, a pergola is often the better value. Want a fully covered freestanding structure? Take a look at our gazebos too.
