2026 Edition
Everything Chicago homeowners need to know about louvered roof systems: costs, permits, brands, and ROI.
What Exactly Is a Louvered Pergola?
Unlike a traditional wooden pergola with fixed slats that only provide partial shade, a louvered pergola features a motorized roof made of aluminum blades. These blades rotate up to 135 degrees, giving you complete control over your outdoor environment.

Frequently Asked Questions
Get answers to the most common questions about louvered pergolas.
How much does a louvered pergola cost in Chicago?
For a high-quality system derived from US aluminum (StruXure, Azenco), expect $120-$180 per sq. ft. fully installed. A typical 12x16 project ranges from $25,000 to $40,000 depending on screens, lights, and heaters.
Do I need a permit for a louvered pergola?
Yes. In almost every municipality from Wilmette to Lake Forest, a louvered pergola is considered a permanent structure. It requires zoning approval (setbacks/coverage) and a building permit. We handle this entire process.
Can it handle Chicago winters?
Absolutely. Our systems are engineered for heavy snow loads. The louvers seal tight and are designed to support wet heavy snow. We recommend leaving them slightly cracked or fully closed depending on the specific model's winter protocol.
Does it add value to my home?
Yes. Unlike a fast-depreciating awning, a permanent aluminum structure is appraised similarly to a sunroom or high-end deck. It expands usable square footage, which is a key value driver.
