A pergola has an open or slatted top for partial shade and airflow, so it offers little rain protection. A covered patio is a solid roof attached to your house, giving full shade and weather cover. A pavilion is a freestanding structure with a full roof. In the rainy Pacific Northwest, covered patios and pavilions keep the space usable year-round.
The Quick Difference Between the Three
All three structures create a defined outdoor living space, but they differ most in the one thing that matters most here: how well they keep the rain off. Choosing between them comes down to how much weather protection you want, whether the structure attaches to your home, and how you plan to use the space through our long wet season.
Below, we break down each option, compare them side by side, and give you a simple way to match the right structure to your goals.
Pergolas: Open Structure, Architectural Style
A pergola is an open framework of posts supporting a roof of rafters or slats. It defines a space and casts dappled shade, but the open top means sun and rain still pass through unless you add a canopy, retractable cover, or louvered roof system.
Pergolas shine as architectural features, framing a patio, dining area, or hot tub and supporting climbing plants or string lighting. For a garden-forward backyard, an open pergola strikes a balance between structure and openness. If you want that look with more rain control, a custom pergola from an experienced installer can be built with a solid or louvered top.
- Best for: partial shade, defining a space, and architectural interest
- Rain protection: limited unless upgraded with a solid or adjustable roof
- Attachment: freestanding or attached to the house
Covered Patios: Full Weather Protection, Attached to Your Home
A covered patio is a solid, permanent roof attached to your home, extending the roofline over a patio or deck. Because it ties into the house, it offers full shade and reliable rain protection, so the space stays dry and usable even during a steady Northwest downpour.
This is often the most practical choice for homeowners who want to use their outdoor space year-round. A covered patio can incorporate recessed lighting, ceiling fans, heaters, and even an outdoor kitchen. Since it connects to your home’s structure, design and construction should be handled by a design-build team that understands flashing, drainage, and load. Explore options with a covered patio installation specialist to match the addition to your home’s architecture.
- Best for: full weather protection and year-round use
- Rain protection: excellent, a solid permanent roof
- Attachment: attached to the home
Pavilions: Freestanding Outdoor Rooms
A pavilion is a freestanding structure with a full, solid roof, supported by its own posts and set apart from the house. Think of it as a standalone outdoor room, ideal for anchoring a dining area, lounge, or outdoor kitchen in the middle or far corner of a yard.
Because it is detached, a pavilion gives you flexibility in placement and can become a destination within a larger landscape. It provides the same full rain and sun protection as a covered patio, but without tying into your home’s roofline. Pavilions pair naturally with a professionally built deck or paver patio as a foundation.
- Best for: a freestanding outdoor room set away from the house
- Rain protection: excellent, full solid roof
- Attachment: freestanding

Which Backyard Structure Fits Your Goal?
Start with how you want to use the space:
- Want an open, breezy feel and architectural interest? A pergola is the classic choice.
- Want to use your patio in every season, rain or shine? A covered patio attached to your home delivers the most reliable protection.
- Want a destination structure away from the house? A pavilion creates a freestanding outdoor room.
The right choice also depends on your lot, your home’s architecture, drainage, and any permit requirements. Our team helps homeowners across the Eastside, including Woodinville remodeling projects, weigh these trade-offs and design a structure that fits the way they live outdoors.

Frequently Asked Questions
Which structure gives the best protection from Pacific Northwest rain?
Covered patios and pavilions both have solid roofs, so they keep the space dry through steady rain. A standard pergola offers only partial shade and limited rain cover, though it can be upgraded with a solid or louvered roof to improve protection.
Do I need a permit to build a pergola, covered patio, or pavilion?
Many backyard structures require a permit, especially larger, roofed, or attached ones, though requirements vary by city and project. It’s best to verify with your local jurisdiction or let your contractor confirm what’s needed for your property before the design is finalized.
Can a pergola be modified to keep out rain?
Yes. A pergola can be built or retrofitted with a solid roof panel, a louvered (adjustable) roof, or a retractable canopy. These upgrades add cost but let you keep the open, architectural look while gaining real weather protection.
Should my structure attach to the house or stand alone?
It depends on your layout and goals. Covered patios attach to the home and extend your living space directly off the house. Pavilions stand alone, making them ideal for a destination spot elsewhere in the yard. Both work well when properly designed and anchored.
