Louvered Pergola vs. Retractable Roof Pergola: Which KE Outdoor Design System Is Right for Your New England Home?

March 12, 2026

A side-by-side guide from an authorized KE dealer with 125 years in the New England shade industry

If you’ve been researching pergola options, you’ve probably come across two very different types of systems: louvered roof pergolas (like the KE Kedry series) and retractable roof pergolas (like the KE Isola). Both are beautifully engineered. Both handle New England weather. But they work differently, look different, and suit different homeowners.

This guide breaks down exactly how each system works, where each one excels, and how to decide which is the right investment for your specific space — from a team that installs both across Massachusetts, Cape Cod, Rhode Island, and Southern New Hampshire.

QUICK ANSWER

The Kedry (louvered) gives you year-round weather control with adjustable aluminum blades — ideal for homeowners who want maximum flexibility and a permanent outdoor room. The Isola (retractable fabric) gives you a fully open sky on demand with clean, elegant aesthetics — ideal for seasonal outdoor living with easy open-air access. Both are premium KE Outdoor Design systems installed by Dorchester Awning.

They are built in the USA and carry CE certification for structural performance. As an authorized KE dealer, Dorchester Awning handles design, permit coordination, and professional installation — so you get the full KE system experience backed by 125 years of local expertise.

How Each System Works

Kedry — The Louvered Pergola

The Kedry system uses motorized aluminum louver blades on the roof. At the touch of a button, the blades rotate up to 135° — from fully open (letting in sun and breeze) to fully closed (waterproof, with rain draining down through internal gutters in the posts). The Kedry Skylife model adds a retract function: the blades can both rotate and slide back, opening the roof completely.

Isola — The Retractable Fabric Roof

The Isola uses a high-tech, waterproof fabric roof that retracts fully on a motorized track system. Its softly arched profile channels rainwater into internal gutters. When open, the fabric disappears completely, leaving an unobstructed view of the sky. When closed, it creates a weather-protected outdoor room with a clean, architectural aesthetic.

Both systems are available wall-mounted or freestanding, can be expanded with modular units, and can be enclosed on all sides with optional drop screens, sliding glass panels, or curtains.

Which System Is Right for You?

Choose the Kedry (Louvered) If…

You want to use your outdoor space year-round — the aluminum structure handles New England snow loads and coastal wind.
You want infinite shade control — rotate louvers to any angle for partial sun, filtered light, or full cover.
You live on the coast or Cape Cod — the all-aluminum construction is salt-air resistant and built for exposure.
You want the outdoor room to feel like an extension of your home — add sliding glass panels and drop screens to fully enclose the space.
You want smart home integration — Kedry connects to smartphone apps, tablets, and voice-activated systems like Alexa.
You’re building a long-term, permanent structure — the Kedry is an investment that adds lasting architectural value.

Choose the Isola (Retractable Fabric) If…

You want a completely open sky when the weather is beautiful — the fabric retracts fully and disappears.
You prefer a softer, more elegant aesthetic — fabric roofs give a warm, residential feel that suits traditional New England architecture.
You use your deck or patio primarily in spring through fall — the Isola is exceptional in three-season applications.
You want weather protection without the visual weight of an aluminum structure — the Isola’s profile is notably slim.
You’re enclosing a space that already has some architectural shelter — a covered porch, sunroom addition, or screened-in patio.

Why New England Is Uniquely Suited to KE Pergola Systems

New England outdoor living comes with a set of challenges most shade systems weren’t built for: humid summers, hard autumn rains, nor’easters, salt air on the coast, and winter snow loads. A standard pergola — wood or aluminum with an open lattice top — leaves you exposed from May through October and unusable from November through April.

KE systems change that equation entirely. Here’s why they perform here:

Internal drainage: Both the Kedry and Isola route rainwater through gutters inside the structural posts — no edge drip, no pooling, no rushing water off the edge onto your guests.
Wind resistance: KE systems are engineered and certified to handle significant wind loads — critical for exposed decks on the South Shore, Cape Cod, and coastal Rhode Island.
Aluminum construction (Kedry): Powder-coated extruded aluminum resists oxidation, UV, and salt air. Unlike wood pergolas, it won’t warp, rot, or require annual refinishing.
Snow load engineering (Kedry): The Kedry’s aluminum blade structure is rated for snow loads — you can leave it in place year-round.
Fabric retraction (Isola): The Isola’s waterproof fabric can be retracted entirely in winter, extending its lifespan and protecting the material from harsh freeze-thaw cycles.
Smart sensors: Both systems can be paired with wind and rain sensors to auto-close when conditions change — essential when a summer storm rolls in off the ocean faster than you can react.

Turn Your Pergola Into a Four-Season Outdoor Room

Both the Kedry and Isola support a full range of enclosure options that transform an open pergola into a true outdoor living space — extending your season deep into autumn and making early spring comfortable months sooner.

Drop screens: Motorized side screens in transparent, light-filtering, or blackout fabrics roll down from inside the frame and disappear completely when not in use. Perfect for blocking coastal winds without closing off the view.

Sliding glass panels: The KE Line Glass system — available for the Kedry — uses powder-coated aluminum frames with 10mm tempered glass panels to fully enclose the space with sliding doors. This is what takes a pergola from a patio cover to a proper outdoor room.

LED lighting: Integrated LED strips can be added to the perimeter of the structure, inside the frame, and along the posts — creating evening ambiance without exterior fixtures.

Curtains and drapes: For a softer, more residential aesthetic, both systems accept optional curtain kits — adding privacy and elegance without the visual weight of screens.

TIP FOR NEW ENGLAND HOMEOWNERS

The combination that performs best in our climate: a Kedry louvered roof paired with drop screens on the windward side and sliding glass on the side facing the water or prevailing weather. You get full enclosure in a storm, complete openness on beautiful days, and everything in between with the touch of a button.

Frequently Asked Questions

What is the difference between a louvered pergola and a retractable roof pergola?

A louvered pergola uses motorized aluminum blades on the roof that rotate to control sunlight, shade, and ventilation while remaining waterproof when closed. A retractable roof pergola uses a fabric or panel roof that slides back on a track to fully open the space to the sky. The louvered system gives you more intermediate control and is generally better for year-round use. The retractable fabric system gives you a completely clear overhead view when open and a softer aesthetic when closed.

What is the KE Kedry pergola?

The KE Kedry is a family of motorized louvered pergolas made by KE Outdoor Design, an Italian-engineered, American-built manufacturer. The Kedry series — including the Kedry Plus, Kedry Prime, and Kedry Skylife — uses extruded aluminum construction with adjustable blade roofs that rotate up to 135°. The Kedry Skylife model adds a full retract function, allowing the blades to both rotate and slide back. All Kedry systems include internal rain drainage, optional LED lighting, and smart home compatibility.

What is the KE Isola pergola?

The KE Isola is a retractable roof pergola system by KE Outdoor Design. It uses a high-tech, waterproof fabric on a motorized track that retracts fully to reveal an open sky. The Isola’s softly arched roof profile directs rainwater into internal gutters and through the posts. When the fabric is retracted, it disappears completely into the frame, leaving a clean, minimal structure. The Isola is a popular choice for homeowners who want the ability to choose between full shelter and a completely open-air space.

Can a KE pergola handle New England winters?

Yes — with some differences between systems. The Kedry’s aluminum blade structure is engineered for snow and wind loads and can remain in place year-round. The Isola’s fabric roof is best retracted during winter months to protect the material from freeze-thaw cycles and heavy snow accumulation — the underlying aluminum frame stays in place. Both systems are built from powder-coated extruded aluminum that resists corrosion, UV, and salt air, making them well-suited to New England coastal environments.

How much does a KE pergola cost?

KE pergola systems — including the Kedry and Isola lines — are premium products that typically range from $15,000 to $40,000+ installed, depending on size, configuration, enclosure options, and site requirements. Pricing varies based on your specific project. Dorchester Awning provides free on-site consultations and detailed written quotes. We also offer financing options.

Do I need a permit to install a pergola in Massachusetts or Rhode Island?

Permitting requirements vary by municipality. Freestanding structures and wall-mounted pergolas above a certain size typically require a building permit in most Massachusetts and Rhode Island towns. Dorchester Awning has licensed construction supervisors on staff and handles permit applications in-house as part of our full-service installation process.

Does Dorchester Awning install KE pergolas on Cape Cod?

Yes. Dorchester Awning installs KE Outdoor Design pergolas throughout the Cape Cod region, including in Chatham, Falmouth, Barnstable, Sandwich, and Truro, as well as across Greater Boston, the South Shore, Rhode Island, and Southern New Hampshire. We have extensive experience with the coastal and salt-air conditions that make Cape Cod properties unique.
