Off-House Pergolas

An off-house pergola is a permanent shade structure that mounts directly to the exterior wall of your home, creating a covered outdoor extension over your patio or deck. Our off-house pergolas are built with aluminum-reinforced frames and maintenance-free extruded vinyl, available in traditional and modern styles with slatted roofs for filtered shade or solid polycarbonate roofs for full rain protection. Choose your size, style, shade coverage, and color to configure the right structure for your home.  [read more]

What Is an Off-House Pergola?

An off-house pergola is a permanent outdoor shade structure that attaches directly to the exterior wall of a home or other structure. It uses the wall as one side of its support system, reducing the number of posts required and creating a seamless connection between the home and the outdoor living space beneath it.

How an Off-House Pergola Connects to the Home

The structure mounts to the home's exterior wall using a ledger board — a horizontal member that anchors the pergola in place and transfers load from the roof into the wall. Rafters extend outward from the ledger board and are supported by posts along the outer edge. All of our off-house pergola kits include the ledger board as part of the package.

Off-House Pergola vs. Freestanding Pergola: Key Distinction

An off-house pergola attaches to the home and requires only two or three outer posts, because the wall provides one full side of support. A freestanding pergola stands independently and requires posts on all sides. Off-house layouts are better suited for patios and decks directly adjacent to the home, while freestanding layouts work better for backyard destinations set away from the structure.

Who Should Consider an Off-House Pergola

An off-house pergola is a good fit for homeowners who want to extend their indoor living space outward, create a defined shaded zone directly off the back or side of the home, or add permanent architectural structure to an existing patio or deck. It is also a practical choice when the goal is shade coverage that feels integrated with the home rather than placed independently in the yard.

How an Off-House Pergola Attaches to the House

The attachment process is straightforward but requires proper preparation to ensure the structure is secure, level, and built to last. Our off-house pergola kits are designed to be DIY-friendly while meeting the structural requirements of a permanent installation.

Ledger Board and Wall Attachment

The ledger board fastens to the home's exterior wall using lag screws driven into the structural framing behind the siding. Proper fastener placement and wall material compatibility are the most important factors in a secure installation. Our assembly documentation covers the process for common exterior wall types. Visit our assembly information page for detailed guides and installation videos.

Post Placement and Foundation Prep

The outer posts are set into the ground or mounted to an existing surface such as a concrete patio or deck. Post footings or surface mount hardware are typically required depending on the installation surface. Traditional off-house pergolas allow posts to be placed in the corners or inset up to 36 inches, giving more flexibility around existing patio layouts. Modern off-house pergolas place posts strictly in the corners for a clean rectangular footprint.

DIY Installation vs. Contractor Installation

Our off-house pergola kits include all structural components, hardware, and step-by-step instructions. Many homeowners complete installation without professional help. For those who prefer to hire out the labor, any general contractor familiar with outdoor structures can work from our assembly documentation.

Off-House Pergola Styles: Traditional vs. Modern

Off-house pergolas are available in two design styles — traditional and modern. Both use the same aluminum-reinforced frame construction and extruded vinyl exterior, but they differ in visual profile, decorative options, and post placement rules.

Traditional Off-House Pergolas

Traditional off-house pergolas feature beam and rafter overhangs, decorative end cap options, and post trim rings that give the structure a classic architectural appearance. Overhangs can be set anywhere from flush to 36 inches. Post styles range from 5-inch square to 10-inch round, and end caps are available in scrolled, beveled, or flat profiles. Posts can be placed in the corners or inset up to 36 inches depending on the patio layout.

Modern Off-House Pergolas

Modern off-house pergolas use flush square corners with no beam or rafter overhangs and no decorative end caps. Posts are always placed in the corners, creating a clean rectilinear profile suited to contemporary home exteriors. Post options are 7-inch square (or 8-inch square for black), with or without a lower trim ring.

Choosing a Style Based on Your Home's Architecture

Traditional styles complement craftsman, colonial, farmhouse, and other classic home architectures. Modern styles work well with contemporary, mid-century, and minimalist exteriors. Both are available in white, tan, or black vinyl — white is the most affordable and black is the most expensive across both styles.

Size Ranges by Style

Traditional off-house pergolas are available from 8 to 44 feet along the wall and 8 to 44 feet out from the structure depending on post configuration. Modern off-house pergolas range from 8 to 32 feet in either direction. For help finding the right fit, our shop by dimensions page lets you filter options by width and depth.

Shade and Roof Options for Off-House Pergolas

The shade an off-house pergola provides depends on the roof type selected. Our lineup covers two distinct approaches: slatted roofs for filtered shade and solid polycarbonate roofs for full rain and UV protection.

Slatted Roofs: 50%, 75%, and 90% Shade Coverage

Traditional and modern off-house pergolas use fixed angled roof slats — also called shade purlins — spaced to yield 50%, 75%, or 90% shade coverage. The 50% option allows more light through and suits spaces where some natural sunlight is desirable. The 75% option offers a balanced level of shade for most patio dining and seating uses. The 90% option provides the densest shade available in our slatted systems and works best for patios with heavy direct sun exposure. Browse the full selection of pergolas with slatted roofs.

Solid Roof Patio Covers for Rain Protection

If keeping the space dry during rain is as important as blocking sun, an attached patio cover with a solid polycarbonate roof is the right choice. These structures attach to the home the same way as slatted off-house pergolas but use an enclosed roof panel that blocks rain entirely. Roof panels are available in white or bronze, and both provide 100% UV protection while reducing the temperature under the structure by up to 15 degrees.

Slatted Pergola vs. Solid Roof: Which to Choose

A slatted off-house pergola is the better fit when filtered light and an open-air feel are priorities. A solid roof patio cover is better when year-round usability regardless of weather is the goal. Climate, sun exposure, and how often the space will be used on rainy days are the most useful factors when choosing between the two.

How to Choose the Right Off-House Pergola for Your Home

Selecting the right off-house pergola comes down to five decisions: size, style, shade coverage or roof type, color, and optional add-ons. Working through each in order keeps the process focused and ensures the final configuration fits both the space and the intended use.

Start with Size

Measure the width of your patio along the home's wall and the depth you want to cover going outward. Allow clearance for post placement, furniture, and walkways. Traditional off-house pergolas support widths up to 44 feet and depths up to 44 feet depending on post count. Modern off-house pergolas support up to 32 feet in either direction. Larger configurations require additional posts to maintain structural integrity across longer spans.

Choose a Style Based on Your Home's Exterior

Traditional pergolas offer more decorative customization — overhangs, end caps, and varied post profiles — and suit classic home styles. Modern pergolas offer a cleaner, more minimal look with flush corners and corner-mounted posts, suited to contemporary exteriors. Both are equally durable and carry a lifetime warranty.

Select Shade Coverage or Upgrade to a Solid Roof

If shade is the primary goal, choose slatted roof coverage at 50%, 75%, or 90% based on sun exposure and personal preference. If keeping the space dry is also a priority, consider upgrading to an attached patio cover with a solid polycarbonate roof. Both options are available in the same vinyl colors and across similar size ranges.

Factor in Add-Ons and Long-Term Value

Optional add-ons include fan mounts for ceiling fan installation and hurricane brackets for areas that experience winds of 80 MPH or higher. Adding hurricane brackets to a traditional off-house pergola or attached patio cover also includes a lifetime wind damage warranty. The aluminum-reinforced frame and thick extruded vinyl exterior require no painting, staining, or refinishing over time. For homeowners comparing vinyl pergolas to wood alternatives, the reduction in long-term maintenance is a meaningful factor in total value.
